Well by the amount that you weigh by different galaxies
Answer;
= 312 Newtons
Explanation;
The bullet has a mass of 0.005 kg, and a velocity of 320 m/s, so we need to find it's final kinetic energy.
KE = 1/2*m*v^2
= 1/2*0.005*320^2
= 256 Joules.
Divide this by the distance over which this energy was received and you have the force that provided that energy.
= 256/0.820 = 312.195 Newtons
Rounded off, this is 312 N
They can continue moving without the need of an external force
Explanation:
Newton's first law of motion states that:
"An object in motion at constant velocity (or at rest) will continue moving at constant velocity (or will stay at rest) unless acted upon an external force"
In normal daily life, we normally experience something different: when we throw an object on a table, for instance, we notice that the object will eventually stop, instead of keep moving. This is because there is another force acting on the object, the force of friction, opposite to the motion, that "resists" the motion of the object eventually bringing it to a stop.
In space, however, there is no force of friction or air resistance. Therefore, Newton's first law can be applied: and so, if space travellers are in a ship, and this ship is moving at a certain constant velocity, it will keep moving at this velocity without slowing down, and no external force would be needed in order to keep the ship in motion.

Answer:
Induced EMF in the loop is 80 volts.
Explanation:
Given that,
Magnetic field, 
Time, 
Area of the loop, 
We need to find the magnitude of the average value of the emf induced in the loop. Due to change in magnetic field, an emf is induced in the loop which is given by :
So, the value of induced emf is 80 V. Hence, this is the required solution.
Answer:
The statement is false. See the explanation below, please.
Explanation:
The kinetic energy is that which is associated to the movement and the potential energy has been related to the position of a certain object. The sum of both, make up the mechanical energy.
