Light travels through space at a speed of 3.0 x 108 m/s. A space probe is
traveling toward Earth at 2.5 * 108 m/s when one of its spotlights is turned
on. What speed would an observer on Earth measure for the light from the
spotlight?
O A. 2.5 * 108 m/s
O B. 3.0 x 108 m/s
O c. 5.5 x 108 m/s
O D. 0.5 x 108 m/s

Answers

Explanation:

The answer is (B). The speed of light is the same for all observers regardless of their motion relative to the light source.

The speed would an observer on Earth measures for the light from the spotlight will be 3×10⁸ m/sec.

What is speed?

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its si unit is m/sec.

The given data in the problem is;

The speed of light is, [tex]\rm C =3 \times 10^8\ m/sec[/tex]

All frames of reference have the same speed of light in a vacuum. Therefore the speed would an observer on Earth measures for the light from the spotlight will be 3×10⁸ m/sec.

Hence option B is correct.

A virtual image is produced by a convex mirror that is 1.60 cm from the mirror. If the magnification is 0.20, how far from the mirror is the object?

Answers

1.80 If I had to guess

The distance of the object from the mirror Is = –8 cm

Calculation of the object distance of a mirror

The image distance from the mirror = –1.60cm

The magnification of the image = 0.20

The distance of the object from the mirror can be calculated using the formula below:

magnification= – image distance/ object distance

Substitute the available values into the equation above,

0.20 = – 1.60/ X

Make X the subject of formula,

X = – 1.60/0.20

X = – 8cm

The negative sign indicates that the image is virtual which is formed behind the mirror.

Therefore, the distance of the object from the mirror Is = –8 cm.

You have just learned that the planet core of Mars is no longer radiating heat like the core of Earth. With this information what would you communicate to building designers as the lead geologist in regards to suitable building locations on the surface of Mars? Remember your informing builders about locations that would best avoid natural disasters like marsquakes and volcanoes? What evidence or theories do you have to support your statements?

Answers

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.

A bird in flight pushes itself upward with
a 7.28 N force. If the bird is climbing at a
constant rate of 1 m/s (no acceleration),
what is the weight of the bird?
[?] N

Answers

Answer:

The weight of the bird is equal to 7.28 N.

Explanation:

The upward force acting on the bird = 7.28 N

The bird is climbing at a constant rate of 1 m/s.

We need to find the weight of the bird.

We know that the weight of an object is the force of gravity acting on it. It can be calculated as follows :

W = mg

In this case, 7.28 N of force is acting on the object. Hence, the weight of the bird is equal to 7.28 N.

Answers

Answer:

Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.

Explanation:

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. ... Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths.

An alpha particle (charge 2e) is sent at high speed toward an atomic nucleus. The electric force acting on the alpha particle is 79.8 N when it is 2.29 x 10(-14) m away from the nucleus. What is the charge on the atomic nucleus? (e = 1.60 x 10(-19) C, Kc = 9 x 10(9) N•m(2)/c(2)

Answers

Answer:

1.45×10⁻¹⁶ C

Explanation:

Applying,

F = kqq'/r²................ Equation 1

Where F = force acting on the alpha particle, k = coulomb's constant, q = charge on the alpha particle, q' = charge on the atomic nucleus, r = distance of seperation between the alpha particle and the atomic nucleus.

make q' the subject of the equation

q' = Fr²/(kq)................. Equation 2

From the question,

Given: F = 79.8 N, r = 2.29×10⁻¹⁴ m, q = 2e = (2×1.6×10⁻¹⁹) = 3.2×10⁻¹⁹ C, k = 9×10⁹ Nm²/C²

Substitute these values into equation 2

q' = [79.8×(2.29×10⁻¹⁴)²]/(3.2×10⁻¹⁹×9×10⁹)

q' = (4.18×10⁻²⁶)/(2.88×10⁻¹⁰)

q' = 1.45×10⁻¹⁶ C

Explain why a kangaroo can jump higher as it's speed increases

Answers

Answer:

See explanation

Explanation:

The ability of the Kangaroo to jump higher is due to the stretching of its tendons as its speed increases.

As the tendons are being stretched more and more, the elastic potential energy increases with each increasing stretch.

This elastic potential energy is translated into gravitational potential energy hence the Kangaroo jumps higher as it's speed increases.

The kangaroo can  jump higher as it's speed increases due to the ability of its tendons to stretch more and more.

The jumping of kangaroo can be related with the concept of spring force and spring potential energy. The spring force is given as,

F = kx

And spring elastic potential energy is,

[tex]U=\dfrac{1}{2}kx^{2}[/tex]

In both the cases, k is the spring constant and x is the stretching distance.

When kangaroo try to jump, the tendons provide extra flexibility to jump higher due to the more stretching. Here, the value of x increases. As value of x increases, ultimately more acceleration is provided to increase its speed.

As the tendons are being stretched more and more, the elastic potential energy increases with each increasing stretch.

This elastic potential energy is translated into gravitational potential energy hence the Kangaroo jumps higher as it's speed increases.

Thus, we can conclude that the kangaroo can  jump higher as it's speed increases due to the ability of its tendons to stretch more and more, such that more energy conversion of energy takes place.

A 20 ohm and 60 ohm light bulb are put in series together which one would be brighter?

Answer:

Explanation:

Hi there!

Ohm's Law: [tex]V=IR[/tex] where V is voltage, I is current and R is resistance

Power equation: [tex]P=VR[/tex]

The greater the power of a bulb, the brighter it is.

The bulbs are connected in series, meaning the the current travelling through each will be the same. Plug Ohm's law into the power equation so we just have I and R:

Because the current stays the same, the bulb with greater resistance will have greater power, hence being brighter. Therefore, the 60 Ohm bulb would be brighter than the 20 Ohm bulb.

What is the temperature difference between 65 degree Celcius and 212 degree Farenheit.
Find the temperature difference in both Celcius and Farenheit scale.

212 - 63 = 149

So 65 deg C = 149 deg F
