Answer:
The required elastic potential energy is 0.068J
Explanation:
Given,
Spring force constant, k= 3.4 N/M
Spring stretch length/ Displacement, x= 0.2m
We know,
Elastic potential energy, V= [tex]\frac{1}{2} kx^{2}[/tex]
=[tex]\frac{1}{2}*3.4*(0.2)^{2}[/tex]
=[tex]\frac{0.136}{2}[/tex]
=0.068
∴The required elastic potential energy is 0.068J

What is the centripetal acceleration of moon II? Note: The constant of universal gravity (G) equals 6.674 X 10-11 N·m²/kg?
0.069 m/s2
m
0.024 m/s2
0.081 m/s2
0.040 m/s2
0 0.19 m/s2
Answer:
Explanation:
Centripetal acceleration's equation is:
[tex]a_c=\frac{v^2}{r}[/tex] where v is the velocity of the object (moon II) and r is the radius. We have the radius, but we don't have the velocity, and we can't solve for acceleration until we do have it. Assuming moon II is a circle, or close enough to be called a circle, it has a circumference.
C = 2πr. If we can find the circumference of the circle, we can plug in the orbital period for the time, the circumference for the distance, and solve for velocity in d = rt. So let's do that and see what happens.
C = 2(3.14)(9.0 × 10⁷) and
C = d = 5.7 × 10⁸. Plugging in and solving for v:
[tex]5.7*10^8=v(3.0*10^5)[/tex] and
v = 1.9 × 10³. That is the velocity we can use in the centripetal acceleration equation.
[tex]a_c=\frac{(1.9*10^3)^2}{9.0*10^7}[/tex] and
[tex]a_c=.040\frac{m}{s^2}[/tex]
These are fun!
Motion is
displacement
a change of position in relation to another object
an object you look at to determine if something is moving
speed
Explanation:
When something is moving, we call it is in motion. It can be also defined as a change of position in relation to another object.
When an object is not moving at all, we call that it was at rest.
To be in motion, there must be a change in position.
Hence, the correct options are "a change of position in relation to another object" and "something is moving".
As elevation increases, temperature decreases. At which elevation will sound travel fastest? 500 meters 1,000 meters 1,500 meters 2,000 meters
Answer:
500 meters
Explanation:
Sound travels faster in warmer air because the air particles have more kinetic energy. The highest temperature air is found at the lowest altitude, therefore 500 meters is the elevation that sound travels the fastest from the options provided.

500 meters

Explanation:
HOPE IT HELPS YOU!!
Answer:
7. (C) 12 m/s
8. (D) 44.1 m
9. (C) 9.8 m/s^2
Explanation:
8. y = -(1/2)gt^2
= -(1/2)(9.8 m/s^2)(3 s)^2
= -44.1 m
This means the ball traveled 44.1 vertically downwards.
11. (a)What downward force is acting on you when you go down a waterslide? (b)What type of friction is
present? (c)If the waterslide were dry explain what type of friction in would be and (d)how that
changes your speed? (4 points)
Answer:
a) "gravitation" is the force causing you to go down a waterslide
b) It is "fluid friction" as a solid object (our body) moves over a fluid (the water)
c) It would become "sliding friction" since two solid surfaces slide over each other
d) fluid friction being the weakest friction, switching to sliding friction means a higher decrease in speed and therefore removing the water from a slide will decrease our speed
please help i would really appreciate it
Answer:
Did you try searching it up
Explanation:
what is force of gravity
Answer:
On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

The Doppler shift can be observed when ____________. Check all that apply. Group of answer choices the source of sound moves towards an observer the source of sound moves away from an observer an observer moves towards a stationary sound source an observer moves away from a stationary sound source the observer and sound source move at the same speed in the same direction the observer and sound source move at the same speed towards one another none of these
Answer:
the source of sound moves towards an observe
Explanation:
The Doppler effect is related to waves such as sound or light. the effect causes an increase or decrease in the frequency of sound light or other waves when the souces either move towards or away from the observer. For example the siren of the train to a person on the platform, the redshift seen by astronomers.
Therefore, The Doppler shift can be observed when the source of sound moves towards an observer From a place closer to the observer than the last wave's crest, each consecutive wave crest is sent. Each wave therefore, takes a little less time than the preceding wave to reach the observer.
write a short note on Andromeda galaxy.
Answer:
[tex]\sf\pink{Andromeda \: galaxy}[/tex]
The Andromeda is a galaxy which is nearest to the milky way. It is also named as Messier 31 or M31 or NGC 224. It is a spiral galaxy located at a distance of approximately 2.5 million light years from earth.
another name Andromeda in Hindi is Vaikunth.
Explanation:
The Andromeda Galaxy (IPA: /ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way.

Un proyectil es lanzado con un ángulo de 30⁰ y una velocidad inicial de 20m/s ¿cual es el punto más alto de su trayectoria? ¿cual es su alcanzar horizontal? ¿cuánto tiempo está en el aire¿
Answer:
Thus, the horizontal range is 17.7 m, and the maximum height is 10.2 m.
Explanation:
velocity of projection, v = 20 m/s
Angle of projection, A = 30 degree
The horizontal range is
[tex]R =\frac{v^{2}sin2A}{g}\\R=\frac{20\times 20\times sin60}{2\times 9.8}\\R=17.7 m[/tex]
The maximum height is
[tex]H =\frac{v^{2}sin^{2}A}{2g}\\H=\frac{20\times 20\times sin^{2}30}{9.8}\\H=10.2 m[/tex]

Explanation:
At apogee the moon is at its farthest from earth and thus appears smaller than normal. Because of this it has the smallest angular size in the sky at this time. At apogee the moon is at its farthest from earth and thus appears smaller than normal. Because of this it has the smallest angular size in the sky at this time. True False
Answer:
the statement is FALSE
Explanation:
In the movement of celestial bodies the most common orbit is the ellipse, in this the sun orbits or in this case the planet Earth is in a focus and the lighter body rotates around in a closed orbit.
The closest point is called perigee and the farthest apogee, but throughout the movement the kinetic moment must be conserved, so at the farthest point the speed decreases so that the angular momentum remains constant since the radius is greater.
This phenomenon is also described in Kepler's second law as that the areas must be equal in equal periods of time, so the speed decreases when being further from the Earth.
Consequently the statement is FALSE

A spring is hung from the ceiling. A 0.442-kg block is then attached to the free end of the spring. When released from rest, the block drops 0.150 m before momentarily coming to rest, after which it moves back upward. (a) What is the spring constant of the spring
Answer:
[tex]K=58.8N/m[/tex]
Explanation:
From the question we are told that:
Mass [tex]M=0.442[/tex]
Drop distance [tex]d=0.150[/tex]
Generally the equation for Spring Constant is mathematically given by
[tex]K=\frac{2mg}{x}[/tex]
[tex]K=\frac{2*0.442*9.8}{1.150}[/tex]
[tex]K=58.8N/m[/tex]

What is kinetic energy formula???
Answer :— Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
