A brick of mass 0.8 is accidentally dropped from a high scaffolding. It reaches the ground with kinetic energy of 240J How high is the scaffolding take acceleration due to gravity g be 10 m/s

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

momentum of soft ball three times less than baskey ball

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
