A suitcase of mass 20 kg moves along a conveyer belt at 0.5 m/s. Calculate its kinetic energy.

K.E.=2.5Nm

Explanation:

m=20kg

v=0.5m/s

K.E.=?

K.E.=1/2mv²

K.E.=1/2×20kg×(0.5m/s)²

K.E.=10kg×0.25m²/s²

K.E.=2.5Nm

i hope this will help you :)

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.

explanation:

object 2 because all the other ones are wrong
