C= 5/9*(F - 32) so F=C*9/5 + 32
F= 25*9/5 +32 = 77 Fahrenheit
Answer:
Well, it's because the air offers much greater resistance to the falling motion of the feather than it does to the brick. ... Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together.
Explanation:
Explanation:
(a) Mass of the cars, m₁ = m₂ = 1160 kg
Distance between cars, d = 35 m
The gravitational force between two cars is given by :



So, the force of gravity between the cars is
.
(b)The weight of a car is given by :


W = 11368 N
On comparing,



So, the weight of the car is
times the force of gravitation between the cars.
