can someone please help me in physics :( i need to scale this so i can draw it. i will be so thankful <33
Answer:
Explanation:
This sounds complicated but , Butternight, and maybe there is some difficulty in the ricochet. I think the question is asking if the bullet bounces off a rock and heads North East.... or NE, but you've got it as EN ? Then how far does it go. In my drawing, what is X, is the question.
We need to know how far the bullet travels East, and how far the bullet travels North.
Then we could put those two parts together and find the length of the red line in my drawing. The red line is also referred to as the Magnitude.
To find how far the bullet travels East, use sine and cosine. Do you know these? if not, start knowing :D
Sine(36) = 0.587785....
Cosine(36)=0.809016....
640 * Sine(36) => 640 * 0.587785 = 376.1825.... m North
640 *Cosine(36) => 640 * 0.809016 = 517.7708... m East
Then the total distance traveled by the bullet to the East is 850 + 517.7708 = 1367.7708... m East
we can find the magnitude by using this [tex]\sqrt{North^{2} + East^{2} }[/tex]
[tex]\sqrt{376.1825^{2} + 1367.7708^{2} }[/tex] = 1418.559.... m NE

In neuroanatomy, the advanced colliculus (from the Latin 'upper hill') is a shape mendacity at the roof of the mammalian midbrain. In non-mammalian vertebrates, the homologous shape is known as the optic tectum or optic lobe. The adjective shape tectal is typically used for each system.
In mammals, the superior colliculus forms a chief thing of the midbrain. it's far a paired structure and collectively the paired inferior colliculi form the corpora quadrigemina. The superior colliculus is a layered shape, with a pattern, this is just like all mammals. The layers can be grouped into the superficial layers (stratum opticum and above) and the deeper last layers. Neurons within the superficial layers acquire direct input from the retina and reply nearly solely to visible stimuli.
Many neurons in the deeper layers additionally respond to different modalities and some reply to stimuli in a couple of modalities. The deeper layers also incorporate a populace of motor-related neurons, capable of activating eye actions as well as other responses. In different vertebrates, the number of layers in the homologous optic tectum varies.

According to the Brewster's law The angle of incidence is θ=tan −1n.
What is Brewster's law?
Brewster's law is a relationship for light waves that states that if a light ray is allowed to fall on the surface of the a transparent medium in a way that refracted ray makes a 90° angle with the reflected ray, the maximum polarisation (vibration in one aircraft only) can be achieved. The law bears Sir David Brewster's name, a Scottish physicist who first suggested it in 1811. The illustration depicts a ray of regular (nonpolarized) light with a particular wavelength striking a transparent medium's reflecting surface (e.g., water or glass).
According to Brewster's law,
the angle of incidence at which the reflected light is totally polarized for reflection from air to glass is governed by the relation
n=tanθ
∴θ=tan −1n

A 100gm GOLF BALL MOVING WITH A VELOCITY OF 20m/s COLLIDES WITH A 8kg STEEL BALL AT REST. IF THE COLLISION IS ELASTIC, COMPUTE THE VELOCITIES BOTH THE BALLS AFTER COLLISION
Answer:
Golf ball ([tex]0.1\; {\rm kg}[/tex]): approximately [tex](-19.506)\; {\rm m\cdot s^{-1}}[/tex] (backwards).
Steel ball ([tex]8\; {\rm kg}[/tex]): approximately [tex]0.49383\; {\rm m\cdot s^{-1}}[/tex] (forward.)
Explanation:
Apply unit conversion and ensure that the unit of all mass are in kilograms: [tex]100\; {\rm g} = 0.1\; {\rm kg}[/tex].
In an elastic collision, both momentum [tex]p = m\, v[/tex] and kinetic energy [tex]\text{KE} = (1/2)\, m\, v^{2}[/tex] are conserved. Momentum of the two balls before the collision are:
[tex]0.1\; {\rm kg} \times 20\; {\rm m\cdot s^{-1}} = 2\; {\rm kg \cdot m \cdot s^{-1}}[/tex] for the golf ball, and [tex]8\; {\rm kg} \times 0\; {\rm m\cdot s^{-1}} = 0\; {\rm kg \cdot m\cdot s^{-1}}[/tex] for the steel ball initially at rest.Hence, the total momentum of the two balls was [tex]2\; {\rm kg \cdot m\cdot s^{-1}}[/tex] before the collision and (by conservation) will still be [tex]2\; {\rm kg \cdot m\cdot s^{-1}}\![/tex] after the collision.
Kinetic energy of the two balls before the collision are:
[tex](1/2)\times 0.1\; {\rm kg} \times (20\; {\rm m\cdot s^{-1}})^{2} = 200\; {\rm kg \cdot m^{2} \cdot s^{-2}}[/tex] for the golf ball, and[tex](1/2) \times 8\; {\rm kg} \times (0\; {\rm m\cdot s^{-1}})^{2} = 0\; {\rm kg \cdot m\cdot s^{-1}}[/tex] for the steel ball initially at rest.Thus, the total kinetic energy of the two balls will be [tex]200\; {\rm kg \cdot m^{2} \cdot s^{-2}}[/tex] before and after the collision.
Let [tex]m_{a}[/tex] and [tex]v_{a}[/tex] denote the mass and velocity of the golf ball after collision; [tex]m_{a} = 0.1\; {\rm kg}[/tex].
Let [tex]m_{b}[/tex] and [tex]v_{b}[/tex] denote the mass and velocity of the steel ball after collision; [tex]m_{b} = 8\; {\rm kg}[/tex].
Total momentum after the collision shall be [tex]2\; {\rm kg \cdot m\cdot s^{-1}}\![/tex]. Thus:
[tex]m_{a}\, v_{a} + m_{b}\, v_{b} = 2\; {\rm kg \cdot m\cdot s^{-1}}[/tex].
Total kinetic energy after the collision shall be [tex]200\; {\rm kg \cdot m^{2} \cdot s^{-2}}[/tex]. Thus:
[tex]\displaystyle \frac{1}{2} \, m_{a}\, v_{a} + \frac{1}{2}m_{b}\, v_{b} = 200\; {\rm kg \cdot m^{2}\cdot s^{-2}}[/tex].
Assume that the unit of [tex]v_{a}[/tex] and [tex]v_{b}[/tex] are both "meters per second" ([tex]{\rm m\cdot s^{-1}}[/tex].) Combine and solve this system of two equations and two variables:
[tex]\left\lbrace\begin{aligned}&0.1\, v_{a} + 8\; v_{b} = 2 \\ &\frac{1}{2}\, {v_{a}}^{2} + 4\, {v_{b}}^{2} = 200\end{aligned}\right.[/tex].
Rewrite the first equation to obtain [tex]v_{a} = 20 - 80\, v_{b}[/tex]. Substitute this equation into the second one to eliminate [tex]v_{a}[/tex]:
[tex]\displaystyle \frac{1}{2}\, (20 - 80\, v_{b})^{2} + 4\, v_{b}^{2} = 200[/tex].
Solve this equation for [tex]v_{b}[/tex]:
[tex]324\, {v_{b}}^{2} - 160\, v_{b} = 0[/tex].
There are two solutions to this quadratic equation: [tex](40 / 81)[/tex] and [tex]0[/tex]. Note that the velocity of the steel ball must be non-zero right after the collision. Hence, [tex]v_{b} \ne 0[/tex]. Therefore, the only possible value for [tex]v_{b}[/tex] will be [tex](40 / 81)\![/tex], which is approximately [tex]0.49383\; {\rm m\cdot s^{-1}}[/tex].
Substitute [tex]v_{b} = (40 / 81)[/tex] back into the first equation of the system and solve for [tex]v_{a}[/tex]: [tex]v_{a} = 20 - 80\, v_{b} \approx (-19.506)\; {\rm m\cdot s^{-1}}[/tex]. Note that the velocity of the golf ball [tex]v_{a}\![/tex] is negative since the golf ball is travelling backwards, opposite to its initial direction of motion.
In other words, the velocity right after collision will be approximately [tex](-19.506)\; {\rm m\cdot s^{-1}}[/tex] (backwards) for the golf ball and approximately [tex]0.49383\; {\rm m\cdot s^{-1}}[/tex] (forwards) for the steel ball.

The students double the mass that hangs from the string. They also replace the original cart with a new cart that has double the mass. By doubling both masses, how will the tension in the string and the acceleration of the cart change?.
The difference between the string's tension and the cart's acceleration is that the tension doubles while the acceleration stays the same.
What does life's stress mean?In common language, tension is the physical and emotional stress that comes along with life's events. Positive or bad situations can cause this stress, which can be physical, psychological, or emotional.
What's an illustration of tension?Compression force's opposite is tension. All of the things in the scene that are in contact with one another apply forces to one another. The best demonstration of a tension force is when a rope is being pulled. The rope builds up a lot of tension when a pulling force is applied to it.

Why do telescopes have to have a good motorized drive system to move them quickly and smoothly?.
Telescopes have to have a good motorized drive system to move them quickly and smoothly so that they can continue to point at the object being observed.
Astronomers use a telescope to observe distant things. Curved mirrors are used by the majority of telescopes, including all large telescopes, to collect and concentrate light from the night sky. The original telescopes employed lenses, which were curved pieces of clear glass, to focus light. The ability of an optical telescope to gather light is its most crucial ability. This capability is solely dependent on the telescope's aperture, or the diameter of the clear objective.
The telescope has a motorized drive mechanism that drives it smoothly from east to west at precisely the same rate that Earth is rotating from west to east in order to maintain the telescope's pointing at the object being seen because Earth is revolving.

there is an inverse relationship between energy of light and wavelength group of answer choices true false
False Relationship between energy to wavelength is also inverse as wavelength to frequency. As wavelength gets shorter ,the energy will increases and vice versa.
Energy can also be linked to light, and there is a clear relationship between energy and wavelength. The energy decreases as the wavelength lengthens and vice versa. Visible light has a lower energy than, for example, X-rays or ultraviolet light and a higher energy than infrared radiation or radio waves. The wavelength has an inverse relationship with the amount of energy because the electromagnetic frequency of the photon is directly proportional to it. The frequency of a photon determines its energy. The energy of a photon decreases proportionally to its wavelength. Longer wavelengths and lower frequencies correspond to warmer colors. Shorter wavelengths and higher frequencies correspond to cooler colors. The Greek letter lambda λ, which represents wavelength, is frequently used.

The critical angle for the total internal reflection using snell's law is
θ(c) = sin⁻¹(n₂/n₁).
Total internal reflection:
Full reflection of a light ray from the surrounding surface is back into a medium like glass or water. If the incidence angle exceeds a specific limitation angle known as the critical angle.
critical angle:
The critical angle is the angle of incidence for which the angle of reflection is 90 degrees. the incidence angle above which 100% internal reflection takes place is known as the critical angle.
Critical angle by using shell's law :
n₁ sinθ₁ = n₂sinθ₂

An in-line skater first accelerates from 0. 0 m/s to 5. 0 m/s in 4. 5 s, then continues at this constant speed for another 4. 5 s. What is the total distance traveled by the in-line skater?.
The total distance traveled by the in-line skater is 33.75 metres.
The total distance will be calculated by the sum of distance due to acceleration and distance due to constant speed. Converting the above mentioned formula in mathematical expression to be used:
d = (v+u/2)×t + v×t
Keep the values in formula to find the total distance.
d = (5+0/2)×4.5 + 5×4.5
Performing addition and multiplication on Right Hand Side of the equation
d = 2.5×4.5 + 22.5
Performing only multiplication on Right Hand Side of the equation
d = 11.25 + 22.5
Performing only addition on Right Hand Side of the equation
d = 33.75 metres
