Using
KE = ½mv² = ½×1500×19×19 = 270750 joules
In general the higher we go the cooler it becomes . temperature fall continues within the lowermost layer of our atmosphere, known as the troposphere. Above the troposphere, the stratosphere exists and in this region the temperature increases with an increase in altitude. The mesosphere is the part of the atmosphere that lies above the stratosphere. In this region, the temperature falls with an increase in altitude. And finally as we continue rising up, we reach the thermosphere, where the temperature increases with increased altitude.
Explanation:
The potential energy is stronger at the start of the bounce and when it is near the end bounce the balls accelerated rate will be lower because the force has decreased . Also I love your profile picture miraculous rocks !
Answer:
τsolid = 0.15 N•m
τhoop = 0.30 N•m
Explanation:
θ = ½αt²
α = 2θ/t² = 2(14)/8.3² = 0.406445 rad/s²
Solid disk I = ½mr² = ½(4.2)0.42² = 0.37044 kg•m²
τ = Iα = 0.37044(0.406445) = 0.150563... N•m
Hoop disk I = mr² = (4.2)0.42² = 0.74088 kg•m²
τ = Iα = 0.74088(0.406445) = 0.301127... N•m
Answer:
Explained
Explanation:
1.Each of the spring scale will read 10N,considering acceleration due to gravity as 10 m/s^2
2.Each of the spring scale will read 10N because each string exerts a force of 10 N to counterbalance the force of 1 kg mass attached to it. This means the tension on the both side of the string is 10 N. So the scale will read 10 N. Also as spring balances are attached in series and kept on table so both spring balances will read same readings.
