Nuclei of uranium atoms split apart is . . . . <u><em>known as nuclear fission</em></u>
Potential difference across the entire cd player is 12 V
Answer:
F= 224 N
Explanation:
Given that
mass ,m = 80 kg
Radius ,r= 5 m
speed at the top v= 8 m/s
The force at the top = F
Now by using the Second law of Newton's
Now by putting the values
Take g = 10 m/s²
F= 224 N
Therefore the force exerted by the track at the top position will be 224 N.
Thanks for points...

Answer:
Pressure,
Explanation:
A 60 kg acrobat performs a balancing act on a cane. The end of the cane, in contact with the floor, has an area of 0.92 cm2. Calculate the pressure the cane exerts on the floor (neglect the weight of the cane).
We have,
Mass of acrobat, m = 60 kg
The end of the cane, in contact with the floor, has an area of,
It is required to find the the pressure the cane exerts on the floor. Pressure exerted by an object is defined as the force acting per unit its area. Its formula is written as :
So, the pressure the cane exerts on the floor is .
