Answer:
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:
- It can be infer that it has a lower frequency.
<em>In the case of electromagnetic waves.</em>
- A short wavelength means a lower energy,
Explanation:
The wavelength is the distance between two consecutive crests or valleys while the frequency is the number of crests that pass for a specific point in an interval of time.
For example, a person makes laundry once a weak.
In this example, the event is represented by the laundry and the interval of time is once a weak
The velocity of a wave is defined as:
(1)
Where is the frequency and
is the wavelenth
(2)
Notice from equation 2 that the wavelength is inversely proportional to the frequency (when the wavelength increases the frequency decreases).
In the case of electromagnetic waves, a short wavelength means a lower energy, as it can be seen in equation 4 (inversely proportional).
