Answer:
The answer is 10.857mJ
Explanation:
The energy stored in this solenoid is given by the below mentioned equation,
where L the inductance of this solenoid is given by the below mentioned equation,
Plugging this into the energy equation you obtain the equation for the total energy stored in the magnetic field of the solenoid, given by,
where is the permeability of free space which equals to . Plugging all the quantities into the above equation from the data in the question after converting to standard units. of meters instead of centimeters, we get for the energy stored in the coil,
Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Part a)
Since the gymnast is holding the rope and remains stationary
So total force is balanced on it
so we will have
T = mg
Part b)
Now gymnast start climbing the rope at uniform speed
so here we have
so again we will have same force equation
Part c)
Now gymnast start climbing up the rope at uniform acceleration
so now we will have
Part d)
Now gymnast start sliding downwards with same uniform acceleration
so now we will have
now we have
Watt is a unit of Power and we know that Power is simply
the ratio of Energy over time. Therefore:
Power = Energy / time
Energy = Power * time
where time is in seconds therefore convert 24 hour to
seconds:
time = 24 hours * (3600 seconds / hour) = 86,400 s
Energy = 60 Watt * 86,400 s
<span>Energy = 5,184,000 Joules</span>
Solid. And it's where molecules don't move at all which means that no energy is required at all.
