acceleration is a vector quantity
The answer is A) Electricity in homes spread extremely .....
Answer: 0.04139m
Explanation:
First, we need to calculate the weight of the man which will be:
Weight = mass × acceleration due to gravity
Weight = mg
Weight = 92.5 × 9.8
Weight = 906.5N
Then, we calculate the force which will be:
F = kx
mg = kx
x = mg/k
x = 906.5/21900
x = 0.04139m.
The spring stretched for 0.04139m.
This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
