Explanation:
Given that,
Mass of a brick, m = 3.1 kg
The dimensions of the brick 225 m x 112 m x 75 m
We need to find the maximum pressure created by the brick. We know that, the force acting per unit area is called pressure exerted. It is given by the formula as follows :
F = mg
A = area with minimum dimensions i.e. 112 m x 75 m
Pressure is maximum when the area is least.
So,
So, the maximum pressure created by brick is .
Answer:
<h2>15m/s</h2>Explanation:
The equation for a traveling wave as expressed as y(x, t) = A cos(kx − t) where An is the amplitude f oscillation,
is the angular velocity and x is the horizontal displacement and y is the vertical displacement.
From the formula; where;
Before we can get the transverse speed, we need to get the frequency and the wavelength.
frequency = 1/period
Given period = 2/15 s
Frequency =
frequency = 1 * 15/2
frequency f = 15/2 Hertz
Given wavelength = 2m
Transverse speed
Hence, the transverse speed at that point is 15m/s
