Answer:
Vertical motion is the movement of an object in a straight line.
When an object is thrown up, it always comes down, as it is affected by the acceleration due to gravity. This is called as vertical velocity.
Power is defined as the rate at which the body is doing work:
Work is defined as displacement done by the force times that displacement:
We know that we need 62N to move the box, so when we apply this force along the path of 10m we have done:
of work.
Now we just divide that by 5s to get how much power is required:
Answer:
14 cm
Explanation:
F = (frac{uv}{u – v})
F = +ve
v = -ve
30 = (frac {25 {times} (-v)}{25 – (-v)})
v = (frac {25 {times} (-v)}{25+v})
v = 14cm
(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)
So happy that i could help you!
Now this question could turn out to be easy for you!!
Answer:
The answer will be 1.344 cents
Explanation:
100 W = 0.1 kW
the kWh =Power(W) x Time(Hour)
0.1 kW x 24 hours = 0.24 kWh
0.24 kWh x 5.6 cents per kWh = 1.344 cents
