It’s frequency is high and microwaves can pass through the atmosphere of the Earth.
Answer:
a. 12 m/s² down
Explanation:
Acceleration has units of length per time squared. Acceleration is a vector, so it also has a direction.
Moment about the pivot must be equal for the seesaw to balance. Initially, the first cat and the bowl are at 2 m from the pivot.
The moment due to cat = 5.3*2 = 10.6 kg.m
The moment due to bowl = 2.5*2 = 5 kg.m
The unbalanced moment = 10.6 - 5 = 5.6 kg.m
Therefore, the 3.7 kg cat should stand at a distance x from the pivot in left to balance the 5.6 kg.m.
That is,
3.7*x = 5.6 => x = 5.6/3.7 = 1.5134 m to the left (on the side of the bowl)
Answer:
<h3>The answer is 0.54 m</h3>
Explanation:
The wavelength of a wave can be found by using the formula
where
c is the velocity
f is the frequency
So we have
We have the final answer as
<h3>0.54 m</h3>
