A rocket of mass 40000kg propelled by a force of 10^6N acquires a speed of 3000m/s determine the power expended
Katyanochek1 [597]

Answer:

3×10⁹ W

Explanation:

Power = work / time

Power = force × distance / time

Power = force × velocity

P = Fv

P = (10⁶ N) (3000 m/s)

P = 3×10⁹ W

Shalnov [3]

Answer:

T_F=\frac{9}{5}(T_K-273)+32

Explanation:

Since the temperature in degrees Fahrenheit in terms of the Celsius is given by the formula T_F=\frac{9}{5}T_C+32 and the temperature in degrees Celsius in terms of the Kelvin temperature is given by the formula T_C=T_K-273, we can use the second formula and substitute it straight into the first formula (since a simplification is not being asked), obtaining T_F=\frac{9}{5}(T_K-273)+32.

jeremie ran around the track at the ymca for 2 hours. when he was done he figured that he had traveled 20 kilometers. what was h
laila [671]
(1) Speed is the ratio of the total distance covered by the object and the total time it takes for him to finish it. 

    Speed = distance / time 

In this item, we are given that the distance is 20 kilometers and that the time it takes for the trip is 2 hours. Substituting the known values,
   Speed = 20 kilometers / 2 hours 
    speed = 20 km/h

(2) Velocity on the other hand takes into account the displacement of the object from his original position. It is assumed that Jeremie was basically back to his original position after two hours. Hence, the velocity is equal to zero.
