Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
Use pythagorean theorem
to find the opposite side, which is 7.3
so then you can just use inverse sinA=7.3/10 which equals 46.9 degrees
Power is the rate of energy. Mathematically, it is
Power (p) = Energy(E) / Time(t)
Hope this helps!
Answer:
The angular velocity is
Explanation:
From the question we are told that
The mass of each astronauts is
The initial distance between the two astronauts
Generally the radius is mathematically represented as
The initial angular velocity is
The distance between the two astronauts after the rope is pulled is
Generally the radius is mathematically represented as
Generally from the law of angular momentum conservation we have that
Here is the initial moment of inertia of the first astronauts which is equal to the initial moment of inertia of the second astronauts So
Also is the initial angular velocity of the first astronauts which is equal to the initial angular velocity of the second astronauts So
Here is the final moment of inertia of the first astronauts which is equal to the final moment of inertia of the second astronauts So
Also is the final angular velocity of the first astronauts which is equal to the final angular velocity of the second astronauts So
So

Answer:
Technician B
Explanation:
here on analyzing both the statements from technician A and technician B. The Statement from Technician B is more logical and correct. That the power-assisted brake system reduces the force that the driver must exert on the brake pedal.
The power-assisted brake system does not reduce the distance of stopping. What it does is it reduces the force to be applied by the driver. Thus, making the drive more comfortable.
