While spending the day relaxing on the beach, Keisha notices that the Sun appears to move across the sky. What is the best explanation for why this is happening?
a. Earth's revolution
b. the Sun's tilt on its axis
c. the Sun's revolution
d. Earth's rotation on its axis

Answers

Answer 1

While spending the day relaxing on the beach, Keisha notices that the Sun appears to move across the sky. The best explanation for this is the Earth's rotation on its axis.

So basically, the earth keeps on rotating about its axis constantly. The change from day to night is due to the phenomenon of Earth's rotation on its axis only. The sun remains fixed, but the earth rotates. So for a person on earth, it seems like the sun rises and moves across the sky and then sets, but in reality, it is the earth that rotates on its axis.

Which of the following actions, if done independently; would increase the maximum height reached by the ball?

a. reducing the spring constant k
b. increasing the spring constant k
c. decreasing the distante the spring is compressed
d. increasing the distance the spring is compressed
e. decreasing the mass of the ball

Answers

Increasing the spring constant k, increasing the distance the spring is compressed, decreasing the mass of the ball will increase the maximum height reached by the ball.

What is meant by maximum height reached by the object?

An object thrown vertically up will rise to its maximum height in direct proportion to its initial velocity, u.

First, as compression distance and spring constant k are raised while mass is decreased, maximum height will increase. As a result, we can select the best course of action by first raising the spring constant. Next, we have the option of extending the distance. Lastly, the spring is compressed, reducing the ball's bulk.

two people are pulling on the ends of a rope. each person pulls with a force of 100 n. the tension in the rop is:

Answers

Option C 100 N is correct. Given that no element of the system is in motion, a person pulling with 100 N of force at either end of the rope is met with a 100 N tension in the rope.

Because the rope is subjected to the same pulling force on both sides, it is in a state of static equilibrium (i.e. it is at rest consequently has a net force of zero). Tension on a rope will be zero if it is pulled from its ends by two opposing forces of 100N each since both forces have identical magnitude but operate in different directions on the same body and cancel each other out.

Is gravitational potential energy a renewable or non-renewable?

Answers

Answer:

It is renewable.

Explanation:

The gravity of the earth is infinite and so it is renewable energy.

Gravitational potential energy is neither renewable nor non-renewable as it is a form of energy that exists due to the position of an object in a gravitational field. It is a type of potential energy that is associated with an object's position in a gravitational field and its mass. The amount of gravitational potential energy an object has depends on its mass, height above the reference level, and the strength of the gravitational field.

What is renewable or non renewable energy ?

Renewable and non-renewable energy sources refer to the sources of energy that are used to generate electricity or power and are consumed over time. Examples of renewable energy sources include solar, wind, and hydropower, while non-renewable energy sources include fossil fuels such as coal, oil, and natural gas.

Therefore, gravitational potential energy is not considered a renewable or non-renewable energy source as it is not a source of energy that is harvested or consumed. Rather, it is a property of an object that can be converted into other forms of energy such as kinetic energy when the object falls or is released from its position in a gravitational field.

Answers

Yes, the damping coefficient of a spring-cart system independent of mass. Mass doesn't affect the damping coefficient (since that is assumed constant).

Damping coefficient - The system’s damping coefficient is a measure of how quickly it returns to rest as the frictional force dissipates its oscillation energy.

Damping is experienced by most oscillatory systems such as harmonic oscillators. These systems, when displaced from their equilibrium position, experience a restoring force proportional to their displacement. If a frictional force proportional to the velocity is also applied, the system exhibits damped harmonic oscillation. In a damping phenomenon, the amplitude of the oscillation is decreasing gradually instead of sudden decreasing. When there is a damping in the system then the amplitude decreases and the period increases.

So, We can see that mass will absolutely affect the damping ratio, but not the damping coefficient (since that is assumed constant).

What is the unit of wavelength?

Answers

The unit of wavelength depends on the type of wave being described. In the International System of Units (SI), the unit of wavelength is the meter (m). This is the case for most types of waves, including electromagnetic waves (such as light), sound waves, and mechanical waves.

What is wavelength?

Wavelength is the distance between two consecutive points of the same phase on a wave. It is the distance traveled by a wave in one period (the time it takes for the wave to complete one cycle). The wavelength is usually denoted by the Greek letter lambda (λ).

For example, the wavelength of a radio wave might be measured in meters, the wavelength of visible light might be measured in nanometers (nm), and the wavelength of a sound wave might be measured in centimeters (cm).

In some fields of physics, other units of length may be used to express wavelength. For example, in the field of quantum mechanics, the unit of length is often the angstrom (Å), which is equal to 0.1 nanometers (nm).

The process through which electrons leave a metal's surface after absorbing electromagnetic radiation is known as the photoelectric effect.

Since photons are the units of light, according to Einstein's theory, when a photon collides with a metal's surface, the full photon's energy is transferred to the electron. A portion of this energy is utilized to free the electron from the metal atom's hold, while the remainder is transferred as kinetic energy to the ejected electron.

Three crucial aspects of the photoelectric effect are not explicable by classical physics: (1) the lack of a lag time; (2) the independence of the photoelectrons' kinetic energy from the strength of the incident radiation; and (3) the presence of a cut-off frequency.

Answers

if Ezra reduced the length of the rope to 0.25 meters and  rotational speed is held constant, There is a change of 3.14 m/sec in the velocity when length of rope is reduced from 0.50 to 0.25 m.

What is rotational speed?

The no. of revolutions made by a rotating object in a given defined time is termed as rotational speed.

Solution:

Given:

initially length of rope i.e. R = 0.50m

2 rotations per second = 1 rotation =0.5 sec= T

now after changing ropes length R=0.25 m

Initially velocity of the ball rotating on R =0.50m

⇒v=2πR/T

⇒v=2*3.14*0.50/0.5

⇒v=6.28 m/sec

6.28 m/sec is the velocity of the ball rotating on R =0.50m.

Now to find the velocity of the ball rotating on R =0.25m we use the following eq.

⇒v=2πR/T

⇒v=2*3.14*0.25/0.5

⇒v=3.14 m/sec

3.14 m/sec is the velocity of the ball rotating on R =0.25m

"If the darts are thrown at the same speed then (B) Projectile that travels along trajectory B was projected earlier and (C) Second dart must be projected at angle, such that 0 + 0,8 = 90° is correct."

Initial speed of dart A = u'

Angle of dart A = θ'

Initial speed of dart B = u''

Angle of dart B = θ''

Both darts start out at the same speed,

Thus, u' = u'' = u

The darts are launched one at a time from the same location A, but not simultaneously. However, they cover the same horizontal distance and arrive at B simultaneously.

Since both darts' horizontal ranges are equal,

= [ u²sin(2θ') / g ] =  [ u²sin(2θ'') / g ]

= sin(2θ') = sin(2θ'')

Although θ' is not equal to θ", we can infer that θ" >θ' from the figure.

Since both are acute angles,

= sinθ'' > sinθ'

Multiplying both sides by 2u/g, we get,

= [ 2u X sinθ'' / g ] > [ 2u X sinθ' / g ]

so that the two darts' respective trajectories are as follows:

The electromagnetic spectrum's infrared region is where the earth emits the most energy. When the energy from the sun reaches the surface of the Earth, 49.4% of it is infrared radiation, 42.3% of it is visible light, and 8.3% of it is ultraviolet radiation.After being received from the sun, energy is reflected back into the atmosphere ( in the form of light ). The energy radiated by the Earth is significantly weaker than the Sun because it is much cooler. As a result, it emits infrared radiation ( long wavelength )

As a result, the planet emits the most energy in the infrared region of the electromagnetic spectrum is correct statement .
