Answer:
Explanation:
given,
mass of the car,m = 0.2 Kg
height to width of ramp, y/x = 12/75
initial displacement, L_i = 2.25 m
change in momentum, Δp = 0.58 kg.m/s
distance of change in direction of the ramp, L_f = ?
Using equation
inserting all the values
The car will cost back up to the distance of 0.0196 m
Answer:
The particle of a gas are very far apart from each other.
Explanation:
The states of matter comprises of solid, liquid and gas. The molecules of gas are free because they are not tightly held together by molecular force. The force between the molecules has been broken, hence the particles possesses the freedom to move about thereby possessing high kinetic energy (energy possessed by a body due to its motion). Since this molecules can easily move freely, they are always far apart from each other under ordinary temperature and pressure.
Answer:
400 J
Explanation:
Work is done when a force that is applied to an object moves that object.
The work is calculated by multiplying the force by the amount of movement of an object
W = F * d
here the man has to work against the gravitational field. (against his weight)
F =100 N
Work done = F * d
= 100 * 4
= 400 J
As the wave length increases the energy of the wave decreases as the equation that relates the c=λυ λ is the wave length and υ is the frequency (which is directly proportional to the energy).
In the wave length spectrum, x-ray has a shorter wave length, meaning that
x-ray has a higher energy than ultraviolet waves.
Hope this helps.
