Answer
B. F=ma
Explanation
The Newton's laws of motion tries to explain the how bodies behave and the energy changes when theys are in motion. For the 3 of them to hold, the bodies must be moving in a straight line and with constant velocity.
The second one states that, "the change of momentum of a moving body is directly proportional to the force producing it and it takes place to the direction of force."
From the choices given, the appropriate answer is B. F=ma
Dipper effect of an oncoming train get louder as it approaches and sound diminishes as it goes away sound traveling
<em>Ten games</em> will be played.
The first team can be any one of 5 . For each of those, the opponent can be any one of the other 4 .
Number of ways to pair them up = (5 x 4) = 20 ways .
<em>BUT</em> ... Whether the Reds play the Blues, or the Blues play the Reds, it's the SAME GAME. Each possible game shows up twice in the list of 20 ways. So there are really only 10 different pairs ==> <em>10 games</em> .
So, the average speed of the Cheetah is 17.6 m/s.
<h3>Introduction</h3>
Hello ! I'm Deva from Brainly Indonesia. This time, I will help regarding the average speed. The average speed is obtained from finding the average of the speeds that occur or can be detected from the division between distance and travel time. The average speed can be formulated by :
With the following condition :
= average speed (m/s)- s = shift or distance objects from initial movement (m)
- t = interval of the time (s)
<h3>Problem Solving</h3>
We know that :
- s = shift = 88 m
- t = interval of the time = 5 seconds
What was asked :
- = average speed = ... m/s
Step by step :
So, the average speed of the Cheetah is 17.6 m/s.
