A print paper is 11 inches long and 8.5 inches wide. 1 inch = 2.54 cm, what’s the area in cm2? Report the correct number of significant figures and unit.

The area of a print paper is

Explanation:

Length of a print paper is 11 inches and its width is 8.5 inches.

It is required to find the area of the print paper.

Since, 1 inch = 2.54 cm

11 inches = 27.94 cm

8.5 inches = 21.59 cm

The area of a print paper is given by the product of length and width. So,

So, the area of a print paper is

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
