Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.
Explanation:
That is called a physical trainer or a fitness coach. Hope I helped!
Momentum = mv
= .15 *20
= 3 kgm/s^2
To solve this problem we will apply the linear motion kinematic equations. In which the speed is defined as the distance traveled in a certain period of time. In turn we must emphasize that 1 light year is equivalent to 
. Mathematically the speed is described as,
Replacing,
Therefore the correct answer is D.
Answer:
A net torque applied to an object causes the angular velocity of the object to change.
Explanation:
The rotational equivalence of force is called a Torque. Thus, a net torque will make an object to rotate with an angular acceleration. Due tothe fact that all rotational motions have an axis of rotation, then a torque must be defined about a rotational axis. A force applied to a point on an object about the axis of rotation is known as a torque.
