Answer:
yes it was a constant speed and the car traveled 10 meters in 20 seconds.
Explanation:
Answer:
Subtract the kinetic energy at the bottom from the potential energy loss. The remainder becomes frictional heat.
Potential energy loss:
M g H = 21.7*9.81*3.5 = 745.1 J
Kinetic energy at bottom of slide:
= (1/2) M v^2 = 52.5 J
Answer:
The total angular momentum is 292.59 kg.m/s
Explanation:
Given that :
Rotation of the horizontal circular platform
= 0.919 rad/s
mass of the platform (m) = 90.7 kg
radius (R) = 1.91 m
mass of the poodle
= 20.5 kg
Your mass
= 73.5 kg
speed v = 1.05 m/s with respect to the platform

r = 0.955
Mass of the mutt
= 18.5 kg

Your angular momentum is calculated as:
Your angular velocity relative to the platform is 



For poodle :

Actual 




Disk 

Total angular momentum of system is:
L = 
= (152.04 + 98.76 + 6.9003 + 34.89) kg.m/s
= 292.59 kg.m/s
Nuclear energy is is used practically for many energy requirements because the reactions are controlled to regulate energy output
<h3>What is nuclear energy?</h3>
Nuclear energy is the energy reaelesed during nuclear relations.
Nuclear energy is a clean form of energy which is available in enormous amounts.
Nuclear energy is is used practically for many energy requirements because the reactions are controlled to regulate energy output.
Therefore, the control of nuclear reactions make the use if nuclear energy possible.
