Answer:
4.8 N
Explanation:
For every action, there is a equal reaction.
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.

It"subjects to the jurisdiction thereof".
Answer:
Option A
20 m/s
Explanation:
From the law of conservation of linear momentum, the sum of momentum before and after collision equals zero hence for this case also, the sum of momentum of the two cars before collision should be equal to momentum after collision.
Momentum is given as the product of mass and velocity, where velocity considers the direction. Momentum, p=mv where m is the mass of the object and v is the velocity.
Momentum before collision
Since the velocities of both cars before collision are zero hence their momentum are zero ie 0.5*0+(1*0)=0
Momentum after collision
For 0.5 Kg car, its momentum will be 0.5*-40=-20 Kg.m/s
For the 1 kg car its momentum will be 1*v=1v
v-20=0
v=20 m/s
