Answer:
D. Humidity refers to the amount of water vapor in the air
It’s none of those because it’s moving at a constant rate
Answer:
F=4040.81 N
Explanation:
Given that
Time ,t= 2.45 ms
Mass ,m= 0.055 kg
v= 1.8 x 10² m/s = 180 m/s
We know that rate of change in the linear momentum is known as force.
Momentum P = m v
Therefore force F
F=4040.81 N
Therefore force on the ball will be 4040.81 N
I would think <em>B,</em> along the Amazon River. This is because of the warm climate ad lots of rainfall.
Not including the endpoints, there are 3 nodes.
<h3>
What is a node?</h3>
In a wave, a node is a stationary point. For example in a vibrating string of a guitar, the endpoints would be nodes.
But here we need to ignore the endpoints, we only know that the wave has two wavelengths.
For a wave with N wavelengths the number of nodes that are not endpoints is just given by 2*N - 1 (while if we counted the endpoints we would have 2*N + 1).
So in this case we have N = 2, then there are 2*2 - 1 = 3 nodes.
