Answer:
10.8s
Explanation:
Given parameters:
Force on the car = 3250N
Distance = 35m
Power = 11375W
Unknown:
Time taken = ?
Solution:
To solve this problem;
Power is the rate at which work is done
Power =
Work done = force x distance = 3250 x 35 = 123200J
Now;
11375 =
11375t = 123200
t = 10.8s

Answer:
Assuming the charged density in the insulated solid sphere of radius 3.1m is 8.8e-9, the electric field at 5.2 meters is 73.1256 .
Explanation:
The electric charge linear density is equal to 8.8 x
the radius of the sphere is 3.1m
The magnitude of the electric field at the radius of the sphere equal to 5.2 meters can be calculated with the formula ;
- E = λ / 4πε₀ [ r / α ( α + r ) ]
Solution:
E = 8.8 x / 4πε₀ [ 3.1/ 5.2( 5.2 + 3.1) ]
= 1018.0995 [0.07183]
= 73.1256
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
