1. What is a moments of a force?
2. Give two examples where moments are applied.
3. What are the two factors that affect a moment?
4. What is the principle of moments?
5. Calculate force W.

1) Force is a quantity that is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N." To say "10.0 N" means 10.0 Newton of force. One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. 2) The Principle of Moment states that when a system is in equilibrium the sum of its CLOCKWISE MOMENTS equals the sum of its ANTICLOCKWISE MOMENTS. Some examples where moments (turning effect) are applied involve levers, like seesaws, opening and closing doors, nutcrackers, can openers, and crowbars. 3) the size of the force applied.
the perpendicular distance from the pivot to the line of action of the force. 4) The principle of moments states that when in equilibrium the total sum of the anti clockwise moment is equal to the total sum of the clockwise moment. When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out. 5) Force is equal to mass times acceleration. Force is measured in Newtons. You can use the force equation to also find the mass or acceleration of an object. To calculate the net force acting on an object, it helps to draw a free body diagram.

Answer:

9.9 years

step-by-step explanation:

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
