Answer:

Interference

Explanation:

Interference is the phenomenon in which two waves superimpose to form a wave with smaller, larger or same amplitude.

There are two types of interference namely, constructive interference and destructive interference.

Constructive interference occurs when the waves are in phase and destructive interference occurs when the waves are out of phase.

In a double slit experiment, the two slits acts as sources of light and thus the waves combine to produce interference patterns. When the waves are in phase, that is the angle between them is 0°, they form a constructive interference pattern which gives rise to a light band. When the waves are out of phase, that is the angle between them is 180°, they form a destructive interference pattern which gives rise to a dark band.

Note also that diffraction patterns are also observed for wide slits but can be neglected for smaller slits.

Answer:

Distance = 0.0052 m

Explanation:

Work =1.56J

Force = 300N

Distance = ?

Work=Force*Distance

1.56 J = 300N * Distance

1.56/300 = Distance

0.0052 m = Distance

When the circuit breaker trips and turns off, it can shut off power to the appliance. This not only protects your home from damage, but it also protects the appliance itself.

Explanation:

What is a circuit breaker. A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

Answer:

[tex]0.62\:\mathrm{s}[/tex]

Explanation:

Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:

[tex]10\:\mathrm{ft/s}=3.048\:\mathrm{m/s}[/tex]

We can use the following kinematics equation to solve this question:

[tex]v_f=v_i+at[/tex]

What we know:

Solving for [tex]t[/tex]:

[tex]-3.048=3.048+(-9.8t),\\-6.096=-9.8t,\\t=\frac{-6.096}{-9.8}\approx \boxed{0.62\:\mathrm{s}}[/tex]

Answer:

a) 3.9 x 10⁻⁵ kg

Explanation:

The amount of mass required to produce the energy can be given by Einstein's formula:

[tex]E = mc^2\\\\m = \frac{E}{c^2}[/tex]

where,

m = mass required = ?

E = Energy produced = 3.5 x 10¹² J

c = speed of light = 3 x 10⁸ m/s

Therefore,

[tex]m = \frac{3.5\ x\ 10^{12}\ J}{(3\ x\ 10^8\ m/s)^2} \\\\m = 3.9\ x\ 10^{-5}\ kg[/tex]

Hence, the correct option is:

a) 3.9 x 10⁻⁵ kg

Answer:

Because Jupiter is a much larger planet than Earth, its gravitational pull is 240% stronger than that of earth. This is why sawdust, which is lighter than its equivalent measure of sugar would weigh more on Jupiter.

Explanation:

Let's assume that a type of bag can contain 50 kilograms of sugar. If that same bag was filled up with sawdust instead, it would weigh far less than 50Kg.

If that bag of sawdust, on earth weighed 35Kg for instance, on Jupiter, the new weight would be:

35Kg x 2.4 = 84Kg

Put differently, Jupiter simply has a stronger gravitational pull than earth. This extra pull is attributed to its size.

Answer:

Explanation:

That is a fun question!

Without a hot radiating core like Earth, Mars will have very different geological and seismic events. The Mars core will be relatively cold and there will not be any molten magma. So Mars will not have earthquakes or volcano activities. Both only occur when there is magma flowing or tectonic plate motion and they will not occur with a cold core.

Answer:

Earth rotates on its axis

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.

As a result of the Earth's rotation on it's axis, stars generally appear to move in circular paths through the sky.

Answer:

30 N

Explanation:

The normal force is the component of a contact force that is perpendicular to the surface that an object contacts. This normal force prevents the surfaces from penetrating each other.

Let us assume that the acceleration due to gravity (g) is 10 m/s². Hence the weight of the book (W) is:

W = mass of book * acceleration due to gravity = 3 kg * 10 m/s² = 30 N

The normal force ([tex]F_n[/tex]) is gotten using:

Summation of vertical force = m[tex]a_y[/tex]

[tex]F_y=ma_y\\\\F_n-mg=0\\\\f_n=mg=3kg(10m/s^2)=30\ N[/tex]

Answer:

3.504 MeV

Explanation:

Given that;[tex]\frac{A}{Z} X ---->\frac{A-4}{Z-2} Y +\alpha + Q[/tex]

Also;

[tex]Q= KE_{\alpha } (M_{Y} + M_{\alpha } /M_{Y[/tex])

Mass number of X = 229

Mass number of Y = 225

Mass number of alpha particles = 4

Kinetic energy of alpha particles = 3.443 MeV

Q = 3.443 MeV (225 + 4/225)

Q= 3.504 MeV

Answer:

Explanation:

PE = [tex]\frac{1}{2}k[/tex](Δ[tex]x^2[/tex])

where k is the spring constant and Δx is the displacement of the spring when an object is hung from it. Plugging in:

[tex]PE=\frac{1}{2}(2.5)(.2^2)[/tex] which gives us

PE = .05 J

Answer:

The cup of water at [tex]60^o C[/tex] has more thermal energy.

Explanation:

Warmer objects have faster particles and higher temperatures. If two objects have the same mass, the object with the higher temperature has greater thermal energy.

Answer:

double the force constant

Explanation:

For this exercise we see that the unit mass to the spring executes a simple harmonic motion, the maximum mechanical energy is

             Em = ½ k A²

where A is the range of motion

To double the energy we must increase the amplitude or the spring constant

Therefore, to double the total energy we must increase the amplitude by an amount √2

or we can increase the spring constant to double

The correct answer is to double the force constant

Answer:

El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.

Explanation:

Para determinar la velocidad del perro con respecto al observador sentado desde la playa a través del concepto de velocidad relativa, descrito en la siguiente fórmula:

[tex]v_{P/B} = v_{P} - v_{B}[/tex] (1)

Donde:

[tex]v_{P/B}[/tex] - Velocidad del perro relativo al barco, en kilómetros por hora.

[tex]v_{P}[/tex] - Velocidad del perro con respecto al observador, en kilómetros por hora.

[tex]v_{B}[/tex] - Velocidad del barco con respecto al observador, en kilómetros por hora.

Si sabemos que [tex]v_{B} = 30\,\frac{km}{h}[/tex] y [tex]v_{P/B} = 10\,\frac{km}{h}[/tex], entonces la velocidad del perro con respecto al observador es:

[tex]v_{P} = v_{B} + v_{P/B}[/tex]

[tex]v_{P} = 30\,\frac{km}{h} + 10\,\frac{km}{h}[/tex]

[tex]v_{P} = 40\,\frac{km}{h}[/tex]

El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.

Answer:

Explanation:

I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.

First row, KE = 0

Second row, KE = 220500 J

Third row, KE = 183750 J

Fourth row, KE = 205800 J

That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.
