Answer:
Unit of precision for force is the Newton.
Explanation:
It is the official unit used to describe force in science and mostly abbreviated with the symbol N.
 
        
             
        
        
        
Answer:
F=m x a 
(F is force ,M is mass and A is acceleration)
in thisncase the Mass is given but we need to find ou the acceleration
Formula for acceleration-
a=(v - u)/t
(v is final velocity , u is initiatal velocity and t is time)
a = (0 - 80)/4
a= -80/4
a= -20
By substituting the values-
F= m x a
F= 1500 x -20
F=-30000N
Thus the force acted is -30000N

The force is -12,000 N
Explanation:
First of all, we calculate the acceleration of the ball, by using the following suvat equation:

where:
v = 0 is the final velocity of the baseball (it comes to rest)
u = 40 m/s is the initial velocity
a is the acceleration
s = 2.0 cm = 0.02 m is the displacement of the ball
Solving for a,

Now we can calculate the average force exerted on the ball, by using Newton's second law:

where
m = 300 g = 0.3 kg is the mass of the ball
 is the acceleration
 is the acceleration
Substituting,

where the negative sign indicates that the direction of the force is opposite to the direction of motion of the ball.

Answer: 
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
 
where,
 = initial pressure of gas at STP = 1 atm
 = initial pressure of gas at STP = 1 atm
 = final pressure of gas = 2.67 atm
 = final pressure of gas = 2.67 atm
 = initial volume of gas =
 = initial volume of gas =  
 = final volume of gas = ?
 = final volume of gas = ?
 = initial temperature of gas at STP =
 = initial temperature of gas at STP =  
 = final temperature of gas =
 = final temperature of gas =  
Now put all the given values in the above equation, we get:
 

Thus the final volume will be
