Answer:
Explanation:
The energy and the frequency of electromagnetic radiation inversely proportional to the frequency of radiation.
So, as the wavelength increases, the energy and the frequency decreases.
Answer:
The pitching speed of the ball is 19.7 m/s
Explanation:
- Here, we can use the third equation of motion,
- whereas v represents the final velocity, u represents initial velocity, a is the acceleration due to gravity and s is the displacement or distance an object traveled
- Here, the initial velocity of the the ball is given as zero and the acceleration due to gravity is 9.8 , the distance 's' is given as 20 m
- Using the equation,
- Hence, the pitching speed of the ball is 19.7 m/s
Answer:
evolutionary theory
Explanation:
The evidence is overwhelming that the Grand Canyon was dug over a span of millions of years by the erosive power of the Colorado River and that river’s tributary streams.
This evidence does not support catastrophic theory but it does support evolutionary theory, because it was gradual process and took place overtime. It did not happen in a catastrophic manner.
The acceleration due to gravity is less at the top of mt. everest because its so far from the center of the earth .
Answer:
0 m/s
Explanation:
velocity= change in displacement/ time
at rest, the ball does not travel any distance
0/ t
=0
