Lifting weights, did this yesterday :))
Answer:
0.050V
Explanation:
To solve this problem it is necessary to use the concepts related to the potential between two objects that have a magnetic field, this concept is represented in the equation.
Where,
v= tangencial velocity
B = Magnetic Field
We know for definition that,
Where,
L = length
Angular velocity
We can replace this values in our first equation then,
Integrating we have,
Replacing the values,
Therefore the potential difference between the center of the rod and the other rod is 0.050V
The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
Answer:
470 N.
Explanation:
Using equations of motion:
S = vi*t + 1/2*(a*(t^2))
Given:
S = 0.65 m
t = 1.5 s
vi = 0 m/s
0.65 = 1/2 * (a * (1.5)^2)
a = 1.3/2.25
= 0.578 m/s^2
Force = mass * acceleration due to gravity
= 92 * 0.578
= 53.16 N
Total force = 420 + 53.16
= 473.16 N
= 470 N.
Answer:
The height is the same
Explanation:
Because they were at the same height but they fell at different velocities
