Answer 1

Answer:

1. A moment is a particular point in time. Some moments you remember forever: like the moment you earned your driver's license or the moment you learned that you passed your organic chemistry class. A moment is a short, but unspecified, amount of time.

2. Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

3. The SI unit of pressure is Pascal (represented as Pa) which is equal to one newton per square metre (N/m-2 or kg m-1s-2).

4. Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

5. The buildings and dams are made broader at the base than at the top just to decrease the pressure on the ground.

6. The pressure exerted by the sharp knife edge is more than that exerted by the blunt one because the area on which force is exerted with a sharp knife is very small. Thus, it is easier to cut with the former than with the latter.

7. Broad shoulder straps provide larger surface area. So, the pressure exerted by the bag on the shoulder is less and carrying the bad is easier.

8. The size of a moment depends on two factors: the size of the force applied. the perpendicular distance from the pivot to the line of action of the force.

Answer 2

Answer:

1.In physics, a moment is an expression involving the product of a distance and physical quantity, and in this way it accounts for how the physical quantity is located or arranged.
