Answer:

Explanation:
The buoyant force F is equal to the weight of the displaced fluid. The weight of the displaced fluid is
, where
is the mass of the displaced fluid. The mass of the displaced fluid is
, where
is the density of the fluid and
is the displaced volume, which is equal to the submerged volume of the cilinder
.
Putting all together we have:

The answer is
.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
Determine the escape speed for the rocket from the planet-satellite system:
The potential energy of the rocket due to Ganymede when it is on the surface of the Ganymede is,

The potential energy of the rocket due to Jupiter
when it is on the surface of the Ganymede is,

Here, R is a separation between Jupiter and Ganymede.
To escape from the surface of Ganymede potential energy of the rocket due to Jupiter and Ganymede is equal to the kinetic energy of the rocket.

Answer:
Explanation:you know
circumference of a circle =2*pi*r=?
r=radius of a circle =3m
total distance of 6 revolution =s=6*2*pi*r
again, linear speed =v=s/t=?
t=time =60sec
Answer:
The answer is 1/16
Explanation:
1. Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. 2. The persistence of vision for normal eye is 1/16 if a second.
Explanation:
you take 50 divide by 6 to get the speed and you also do the same as the other one then after you find both speed you first change in km/h and add
