Answer:
The answer is;
The mass of the cable is 7.428 kg
Explanation:
Force = 110 N
Mass of block = 20 kg
velocity = 3.9 m/s
We apply the law of motion which is
v² = u² + 2·a·s
Where a = acceleration
s = distance = 1.9 m and
u = initial velocity = 0 m/s
v = velocity = 3.9 m/s
∴ v² = 2·a·s
3.9² = 2×1.9×a which gives
a = 4.003 m/s²
F= m×a
Where F= Force = 110 N
m = mass
a = acceleration = 4.003 m/s²
∴ m = F/a = 110/4.003 = 27.482 kg
Since the mass of the block = 20 kg
Mass of cable + block = 27.482 kg
Mass of cable = 27.428 kg - mass of block = 27.428 kg - 20 kg = 7.428 kg
Mass of cable = 7.428 kg

The answer is B. The less massive object to orbit the more massive object.
Explanation: The more massive the object, the larger its gravitational pull.
Example: the moon orbits the earth because the moon’s mass is smaller than earth, earth orbits the sun because the earth’s mass is smaller than the sun..
Answer:
USING LAW OF CONSERVATION OF ENERGY
Explanation:
As we know that energy can not be created nor be destroyed.The pendulum cannot continue moving on its own because it meets energy losses due to friction.Its energy is converted into heat energy which dissipates in the air
