The gravitational force on the car is
(9.8 m/s^2) x (the car's mass in kg).
The unit is newtons.
Answer:
The perimeter of the rectangle is 60 units.
Explanation:
The perimeter of a rectangle is given by the equation P = 2L + 2W. With W = 12 units and L = 18 units, substituting the values in the equation above:
P = 2(18 units) + 2(12 units)
P = 36 units + 24 units
P = 60 units
To find power, you have to find work first.
Given :
F = 32kg —> 313.6 N
d = 0.1m
Work = Fd
= (313.6)(0.1)
= 31.36
P=W/t
=(31.36)/(0.83)
≈ 38 W
The correct answer is
<span>Density
In fact, the density of an object is the ratio between its mass m and its volume V:
</span>

<span>if the size of the object changes, its volume V changes as well, therefore the density d must change.</span>
