What us the difference in the ways objects move at a speed of a car and an object mkvinf close to the speed of light?​

Physics
1 answer:
Charra [1.4K]2 years ago
5 0

Answer:

The difference is in who or what is observing the speed.

Explanation:

Giving that speed is relative between the objects and the reference point from which it is being observed.

It is concluded that speed alone has no direct effect on a moving object, hence it is just a determining unit for the difference in distance between two objects.

Therefore, in this case, the difference is in who or what is observing the speed.

A right triangle has sides measuring 5 and 12 inches. If the two vectors have a magnitude of 5 and 12 and are at right angles to
ollegr [7]

Answer:

x=13

Explanation:

From the question we are told that

Magnitude 1 M_1=5

Magnitude 1 M_2=12

Generally the Pythagoras equation for the magnitudes is mathematically given as

\sqrt{x^2}=\sqrt{M_1^2 +M_2^2}

\sqrt{x^2}=\sqrt{5^2 +12^2}

x=13

Therefore resultant magnitude is

x=13

explain how potential and kinetic energy are at play when we talk about Newton's second law of motion
KIM [24]

Potential and kinetic energy are at play when we talk about Newton's second law of motion through the various positions in relation to the bodies involved.

<h3>What is Newton's second law of motion?</h3>

This law states that force is equal to the rate of change of momentum and is denoted as F = mv where m is mass and v is velocity.

Potential energy is the energy is possessed by a body by virtue of its position while kinetic energy is possessed by a body by virtue of its motion. Both forms of energy are influenced by forces and are equal to the total momentum.

A constant net torque is applied to an object. Which one of the following will NOT be constant?
love history [14]

Answer:

B) Angular velocity

Explanation:

The equivalent of Newton's second law for the rotational motions can be written as:

\tau = I \alpha

where

\tau is the net torque applied to the object

I is the moment of inertia

\alpha is the angular acceleration

From the formula we see that when a constant net torque \tau is applied, then the object also has a constant angular acceleration, \alpha.

But we also know that

\alpha = \frac{d\omega}{dt}

where \omega is the angular velocity: so, a constant angular acceleration means that the angular velocity of the object is changing, so the correct answer is

B) Angular velocity

(moment of inertia and center of gravity do not change since they only depend on the mass and the geometry/shape of the object, which do not change)

The data table shows how the amplitude of a mechanical wave varies with the energy it carries. Analyze the data to identify the
Maslowich

The energy of a wave is directly proportional to the square of the amplitude of the wave.

<h3>What is the relationship between energy and amplitude?</h3>

There is direct relationship between energy of the wave and the amplitude of the wave. The energy transported by a wave is directly proportional to the square of the amplitude of the wave. This means if energy is increase the amplitude of wave becomes double and vice versa.

Energy = (amplitude)2

So we can conclude that the energy of a wave is directly proportional to the square of the amplitude of the wave.
