Answer:
Explanation:
Potential difference is created when a long object of length l moves perpendicular to magnetic field . The potential difference created is
V = Blv where B is magnetic field , l is length and v is velocity of length l .
here V = 45 x 10⁻⁶ x 44000 x 1.2
= 2.376 volt .
b )
Electric field = V / l ; V is potential difference between length l .
= 2.376 / 44000
= 54 x 10⁻⁶ V/m
Answer:
Angle of refraction.
Explanation:
Refraction is simply a change in direction of light rays as it enters into another medium.
In the diagram given above, θ2 is simply the angle of refraction showing us that the light ray has changed direction as it moves from one medium to another medium.
Answer:
Explanation:
I dont know if this will help but A two force member is a body that has forces (and only forces, no moments) acting on it in only two locations. In order to have a two force member in static equilibrium, the net force at each location must be equal, opposite, and collinear.
The talk test can be used to measure the <u>intensity of an activity</u>
<u>Option: B</u>
<u>Explanation:</u>
The talk test is usually used to measure the intensity of a particular activity when a person talks during that activity. This is mostly used in cardiovascular patients to measure the intensity of the exercise.
For example, when a person can talk during exercising, it means that he is able to use the oxygen to create energy for the muscles. i.e he will be in aerobic state. Incase, he is not able to talk any more during his exercise, it means that the breathing rate has reached a particular ventilatory threshold.
So now the body is creating energy from the stored system such as muscle glucose and creatine. Thus this talk test helps to determine in which way your body creates energy, aerobic or non aerobic.
I want to help really bad but is there a photo of this ?
