Answer:
The acceleration of the satellite is 
Explanation:
The acceleration in a circular motion is defined as:
(1)
Where a is the centripetal acceleration, v the velocity and r is the radius.
The equation of the orbital velocity is defined as
(2)
Where r is the radius and T is the period
For this particular case, the radius will be the sum of the high of the satellite (
) and the Earth radius (
) :
Then, equation 2 can be used:
⇒ 
Finally equation 1 can be used:
Hence, the acceleration of the satellite is
Yes
Explanation:
Blowing a room-temperature air over an ice block will heat it because of convection.
Convection is one of the heat transfer modes that occurs in fluids.
- In convection, a hot and lighter fluid replaces a denser and cold fluid.
- It involves the actual motion of the particles of the medium.
- In this analogy, the blowing room-temperature is hot and lighter.
- It will replace the air close to the ice block body that is cold and denser
- As the hot air comes near the ice block, it loses some of its heat and warms the cold ice.
- In turn, the air becomes colder and moves away.
- This is simple convection in action.

Answer:
While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter
Explanation:
Answer:
0.196
Explanation:
According to Newton's second law
\sumFx = ma
Fm-Ff = ma
Fm is the moving force
Ff is the frictional force
m is the mass = 9kg
a is the acceleration = 2.4m/s²
Fm = Wsin theta
Fm = 9(9.8)sin25°
Fm = 37.28N
Ff is the frictional force = nmgcos theta
Ff = n(9)(9.8)cos25°
Ff = 79.94n
Substitute the given values into the formula
37.28-79.94n = 9(2.4)
-79.94n = 21.6-37.28
-79.94n = -15.68
n = 15.68/79.94
n = 0.196
Hence the coefficient of kinetic friction between the potted plant and the incline is 0.196
