I'm not from that school but I can help you.
A toaster needs a 110-volt outlet because it doesn’t need
too much electricity. Electricity can be
converted to heat, and toaster only needs to be heated and nothing else that
requires extra electricity while clothes dyer requires higher voltage because
it needs more effort and electricity in order to do its function.
Answer:
Both objects will undergo the same change in velocity
Explanation:
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
m = Mass of object
Any object which is falling has only the acceleration due to gravity.
The acceleration due to gravity on Earth is 9.81364 m/s²
So, the speeds of the objects will change at an equal rate of 9.81364 m/s² but the change will be negative when an object is thrown up.
Hence, both objects will undergo the same change in velocity.
I hope I am correct my Science teacher said this was the answer to your question
