The answer is "B" - If there are no windows then there will be no light coming in, and therefore you don't have to worry about what time of day you do the experiment at.
C. crests. The wavelength is the distance between two specific parts of a wave. This might also be the trough.
Given:
speed of 0.40meters/seconds
1,800 Newton's horizontal force
Required:
Power of the horse
Solution:
P = F(D/T) where P is power in
watts, F is the force, D is the distance and T is time
P = (1,800N) (0.40 meters/seconds)
P = 720 Watts
Answer:
in a kitchen
Explanation:
only if they're producing
Answer:
Induced emf through a loop of wire is 3.5 V.
Explanation:
It is given that,
Initial magnetic flux, 
Final magnetic flux, 
The magnetic flux through a loop of wire decreases in a time of 0.4 s, t = 0.4 s
We need to find the average value of the induced emf. It is equivalent to the rate of change of magnetic flux i.e.



So, the value of the induced emf through a loop of wire is 3.5 V.
