Answer: The temperature and the number of molecules must reamain constant for the law to apply, and as the pressure increases, the volumen decreases proportionally.
Boyle's law states that if the temperature, T, of a given mass of gas, remains constant, the Volume, V, of the gas is in inverse relation to the pressure, p; i.e.
pV = constant (for a given mass of gas, at constant T)
Then, if p increases, V decreases proportionally to keep the relation pV = constant.
Answer:

Explanation:
As per energy conservation we can say that energy stored in the spring at the position of maximum compression must be equal to the kinetic energy of bullet and block system
so here we have

here we know that
k = 205 N/m
x = 35 cm

now by momentum conservation we know that


now plug in all values in it

now from above equation


by solving above equation we have

Answer:
(a). The ball's centripetal acceleration is 
(b). The magnitude of the net force is 232.9 N.
Explanation:
Given that,
Mass of baseball = 144 g
Speed = 81 mph = 36.2 m/s
Distance = 81 cm
(a). We need top calculate the ball's centripetal acceleration just before it is released
Using formula of centripetal acceleration

Where, v = speed
r = radius
Put the value into the formula



(b). We need to calculate the magnitude of the net force that is acting on the ball just before it is released
Using formula of force

Put the value into the formula


Hence, (a). The ball's centripetal acceleration is 
(b). The magnitude of the net force is 232.9 N.
There are 3 states of matter. Solid, Liquid, Gas. An example of each would be ice, water, steam,
