Answer:
The total work that the rope does to Mangnus is - 5780 Jules.
Explanation:
By definition, the work is defined as:
Where F and d are the force and the total displacement. Note that in the definition the product is a scalar product since F and d are both vectors.
Take into account that according to third Newton's law the force that the rope does to Magnus is opposite to the force that Magnus does to the rope, therefore the scalar product will be negative due the rope's force goes against to Magnus displacement.
For calculating the work, we take 2500 N as the value for the force and 2.312 meters as the value for the displacement:

Answer: 0.1416 kg
Explanation:
Total Mass = Mass of beach ball + Mass of air inside
Mass of beach ball = 0.100 kg
Mass of air = density * volume
Density = 1.30 kg/m^3
Radius (r) = 21.6 cm = 0.216 m
Volume (sphere) = π * r^3 = π * (0.216)^3 = 0.032 m^3
Hence:
Mass of air = 1.30 * 0.032 = 0.0416 kg
Total Mass = 0.100 + 0.0416 = 0.1416 kg
Answer:
68.2 Quadrillion meters
Explanation:
A lightyear is the distance that light travels in one year.
Speed of light is 
So light covers 300,000,000 meters in one second.
One year has 31536000 seconds so , light covers

so 7.2 light years is

so 7.2 light years is
6.82 x 10^(16) meters or
68.2 Quadrillion meters
The demand for these things is very high. Everyone wants to have shelter, water, and food. However the demand for shelter is higher because water and food are more accessible.
