Explanation:
Power is the rate of change of force dotted into displacement which is added to the force dotted to the rate of change of displacement.If the force is constant, then you get the instantaneous power is the force dotted to the instantaneous velocity.
Answer:
<u>Speed = 1.2 m/s</u>
Explanation:
<em>Convert 20 min into seconds</em>
<em>1min= 60sec</em>
20min = 20*60 sec
<em>20 min= 1200sec</em>
Time = 1200 sec
Distance = 1000m
Speed =
Speed =
<u>Speed = 1.2 m/s</u>
<u></u>
<em>Hope this helps.</em>
Answer:
9 and 3 N
Explanation:
Forces in the same direction sum up to produce the resultant force;
One force subtract the other will give the resultant force when they are in opposite directions;
Lets say one direction is forwards and the opposite backwards;
We have one force, let's say force A, in the forwards direction and another force, force B, acting in the same (forwards) or opposite (backwards) direction;
If B is acting in the same direction, then the resultant force (in this case) will be as follows:
A + B = 12
If B is acting in the opposite direction, then the resultant force will be as follows:
A - B = 6
Summing the two equations will allow us to solve for A:
A + B + (A - B) = 12 + 6
2A = 18
A = 9
Substitute this into either of the above equations and we can solve for B:
(9) - B = 6
B = 9 - 6
B = 3
Answer:
Do u have a picture of the graph?
Explanation:
I can solve it with refraction
The orbit of a space shuttle is surprisingly like an apple falling from a tree to earth. The space shuttle is simply moving so fast that the path of its fall is an orbit around our planet. Which of Newton’s laws helps explain the orbit of a space shuttle around earth and the orbit of earth around the sun
