Through what angle does it turn during that time interval if the angular acceleration is constant: 32.0rad.
<h3>What is
angular acceleration?</h3>
- Angular acceleration is the term used to describe the temporal pace at which angular velocity varies. Radians per second is the accepted unit of measurement. Consequently, = d d t. Angular acceleration is also known as rotational acceleration.
- Angular acceleration can be calculated by dividing the angular velocity by the acceleration duration. (t). Use pi instead, or the drive speed (n) divided by the acceleration time (t) multiplied by 30. The usual SI unit for the rotational acceleration that results from this equation is radians per second squared (Rad/sec2).
Through what angle does it turn during that time interval if the angular acceleration is constant:
v(initial) = 4rad/s
v(final) = 12
t = 4 sec
a = ?
v(final) = v(initial) + at
12 = 4 + a(4)
a = 2 rad/sec2
s = ?
v(initial) = 4rad/s
v(final) = 12
a = 2rad/sec2
144 = 16 + 4s
s = 32 rads
d) 32.0rad.

Answer: a dark (absorption) line
Explanation:
This is as a result of absorption of electromagnetic a specific wavelength. The pattern followed by such lines is characteristic of specific atoms in the path of radiation.
Answer:
All of the following are true EXCEPT, the angle of refraction is 30 degrees
Explanation:
It is given that,
The index of refraction of the water is 1.33 and the angle of incidence is 30 degrees. We know that when a ray of white light moves through the air and strikes the surface of water in a beaker, refraction occurs. Let r is the angle of refraction. It can be calculated using Snell's law as :
So, the angle of refraction is 22.08 degrees.
According to the law of reflection, the angle of incidence is equal to the angle of reflection. Since, it is incident at an angle of 30 degrees, so the angle of reflection will be 30 degrees. Also, total internal reflection will result, depending on the critical angle.
So, the wrong statement is the angle of refraction is 30 degrees. It is equal to 22.08 degrees.
Answer:
The acceleration produced is
Explanation:
By the second law of Newton, the force F is equal to:
F = ma
Where m is the mass of the object and a is the acceleration produced. So if The force gives the standard 1 kg mass an acceleration of 1.00 m/s2, that means that the force apply on A and B is equal to:
F = (1Kg) * (1.00m/s2) = 1 N
Then, if this force on A produce an acceleration of 0.530 , the mass of A is:
At the same way, if this force on B produce an acceleration of 0.344 , the mass of B is:
Therefore, if they are attached and the same force is applied, the acceleration is:
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
