Amotor has the electrical energy equivalent to 400. joules of work. it can lift a 5.0 kg mass 2.0 meters. calculate the work done by the motor.

Answer : Work done, W = 98 J.

Explanation :

It is given that,

The electrical energy equivalent to 400. joules of work.

The mass that is lifted by the motor, m = 5 kg

Height, h = 2 m

The work done by the motor is given by :

g is acceleration due to gravity

So, the work done by the motor is 98 J

Hence, this is the required solution.  

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

1/0.14nm = 10^10/1.4 a lot
