Consider three starships that pass by an observer on Earth. Starship A is traveling at speed v=c/3v=c/3 relative to Earth and ha

s a clock placed aboard. Starship B is traveling at speed v=c/3v=c/3 relative to Earth and in the same direction as Starship A. Starship C is traveling at speed v=c/3v=c/3 relative to Earth, but in the opposite direction as Starship A. In which reference frame can a time interval be measured that equals the time interval measured by the clock aboard Starship A?

Answer:

T = 1633N

Explanation:

The weight of the man is given by m×g =112×9.8= 1097.6N

Coefficient of Kinetic Friction = frictional force / Normal reaction ( Weight of object)

The coefficient of Kinetic Friction= Tan A

Where A is the angle of inclination

The angle of inclination is Tan^-1{0.876} = 41.21°

By identity sin A = Opposite( weight)/ hypothenus ( Tension)

Hence the tension is T = 1097.6/sin 41.21 =

T = 1633N

A mass of 7.5kg has a weight of 30n on a certain planet calculate the acceleration due to gravitt on this planet
Over [174]

Answer:

Acceleration due to gravity on a certain planet = 4 m/s²

Explanation:

According to the question,

Weight = 30 N

Mass = 7.5 kg

Let acceleration due to gravity be 'a'

<u>Formula</u>:

Weight = Mass × Acceleration due to gravity

30 = 7.5 × a

a = 30/7.5

a = 4 m/s²
