A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers are mainly used to increase or decrease voltage in power lines or electric power applications. So your answer would be D. transformer
Answer:
F = m a = m v / t where v is the change in velocity in time t
F = p / t since m v is equal to p
F = 2.2 (kg m / s) / 1.1 s = 2 kg-m / s^2 = 2 N
Or you can use the impulse equation
Answer:
Explanation:
From the question, we can see that the elevator is at a constant speed, invariably, acceleration is zero. And thus, there is no external force acting in the man, asides from force of gravitation acting on the man between those 5s. Now, we solve the question using newton's second law of motion.
The second law of motion states that, "the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object."
Summation Fy = ma(y)
F(n) - F(g) = 0
F(n) - mg = 0
F(n) = mg
F(n) = 77*9.81
F(n) = 755.37N
Answer:
0.5A
Explanation:
V=IR where V is 1.5V, R is 3 ohms
Hence 1. 5= I x 3
1.5/3 =I
I =0.5 A
Current is 0. 5 amperes
The answer is "C" because the equator is closest to the sun, because the sun's rays hits the earth surface at the higher angel at the equator and also the sun is directly overhead the equator.
