Answer:
v = 15 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of linear momentum, which tells us that momentum is equal to the product of mass by Velocity.
where:
P = linear momentum [kg*m/s]
m = mass = 2 [kg]
v = velocity = 15 [m/s]
![P=2*15\\P=30 [kg*m/s]](https://tex.z-dn.net/?f=P%3D2%2A15%5C%5CP%3D30%20%5Bkg%2Am%2Fs%5D)
Since we know that momentum is conserved, that is, all momentum is transferred to the second body, we can determine the velocity of the second body, since the mass is equal to that of the first body.
![30=2*v\\v = 30/2\\v = 15 [m/s]](https://tex.z-dn.net/?f=30%3D2%2Av%5C%5Cv%20%3D%2030%2F2%5C%5Cv%20%3D%2015%20%5Bm%2Fs%5D)
C. Space.
Radiation is a process by which heat energy is transferred through space.
Answer:
The current in the loop will flow in anticlockwise direction , and the magnetic field created by the induced current point up.
Explanation:
A person usually breathes an average of 13 pints of air every minute.
Lungs aren't the same size. To accommodate the heart, the right lung is larger than the left lung — for humans, that is.
Lungs float on water. ...
Lungs and tennis courts can be the same size. ...
Oxygen only plays a small part in breathing.
