The normal force decreases, this is the frictional force. It will be counteracted by the force which accelerates the brick to slide downward opposite to the end where the board is raised. As the angle increases the force acting upon the brick opposite to the normal force will decrease.
The distance it traveled and the time that it took to travel that distance
Answer:
532.0725 m
102.17270893 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = g
H = Height of cliff
Distance traveled in 3 seconds
Distance traveled by sound = 2H-44.145 m
The height of the cliff is 532.0725 m
Her speed just before she hits the ground is 102.17270893 m/s
Answer:
Amplitude
Explanation:
A wave is a periodic oscillation that carries energy, but not matter, through space or through a medium.
A wave is characterized by the fact that the particles in the medium oscillate around a fixed point, but there is no overall movement of particles in the direction of the wave (this means, only energy is transferred, while matter is not transferred).
A wave is also characterized by several properties, namely:
Amplitude: it is the maximum distance the particles of the medium move from their resting positions
Frequency: the number of oscillations of a certain particle per second
Wavelenght: the distance between two points of the wave that have same shape
Period: the time it takes for one particle of the wave to complete one oscillation
So, the answer is
Amplitude
