77julia77 [94]
Before taking a pressure reading, it is necessary for the technician to first allow the temperature of the cylinder to stabilize to room temperature because a comparison with a temperature-pressure chart is only valid and true when both temperature and pressure of the refrigerant are stable.

What is the approximate weight of a 20-kg cannonball on Earth? 2 N 20 N 196 N 1,960 N
Margaret [11]
Since weight is the force an object is exerting on another object, and the formula to calculate force is Force = Mass * Acceleration, the answer to your question is 196 N, since the mass of the cannonball times Earth's gravitational pull equals 196 N.

Carry's car has a mass of 1000 kg and its brakes can apply 8000 N of force. If she is driving at 24 m/s and sees something in th
-Dominant- [34]

3s

Explanation:

Given parameters:

Mass of car = 1000kg

Force applied = 8000N

speed = 24m/s

Unknown:

time taken for the car to stop = ?

Solution:

According to newton's second law of motion; "the force on a body is the product of its mass and acceleration".

  Force = mass x acceleration

  let us find the acceleration of the car;

     a = \frac{F}{M}  = \frac{8000}{1000}  = 8m/s²

since the car is accelerating at a rate of  8m/s², when the brakes are applied, it will start decelerating at the constant rate, - 8m/s²

Applying the appropriate equation of motion;

     V = U + at

V is the final velocity

U is the initial velocity

a is the acceleration

t is the time taken

        final velocity = 0

       0 = U + at

     -U = at

    -24 = -8t

         t = 3s
