What is the mechanical advantage of a wedge that is 2 inches at its widest part and has a sloped side with a length of 10 inches?a. 0.2b. 5c. 8d. 20

Answers

Answer:

B) 5

Explanation:

Mechanical advantage = D/W

= 10/2

= 5.

It has no unit because the inches in the length and width will cancel out.

Climate gets colder closer to the poles becausea, the ice at the poles absorbs the Sun`s rays.

, atmospheric and oceanic clrulation patterns move cold air toward the poles.

c, heat from the poles is transferred toward the equaror.

d. the Sun`s rays are less concentrated near the poles.

Answers

Answer: The correct answer is- the Sun's rays are less concentrated near the poles.

The axis of the Earth is tilted, which causes the temperature difference between the Equator and polar regions of Earth.

Equator gets direct sunlight during the entire year whereas due to the tilted axis, polar regions are prevented to receive direct sunlight.

Also equator is aligned at 90 degrees to the sun, but as we move towards the poles, the angle of incident sunlight is increased exponentially.

So the intensity of the sun's rays is decreased or sunlight becomes less concentrated near the poles, resulting in colder climate closer to the poles.

Climate gets colder closer to the poles because the Sun`s rays are less concentrated near the poles. The answer is letter D. Also, the Earth is tilted causing the Sun’s ray to be farther from the poles.

Ted wants to hang a wall clock on the wall by using a string. If the mass of the wall clock is 0.250 kilograms, what should be the tension of the string so that it can sustain the weight of the wall clock?

Answers

The clock is pulling the force towards earth's center because of gravity.
That force is equal to:
F = m*g where g is gravitational acceleration.

We will take that g = 9.81m/s^2

Now:
F = 0.25 * 9.81 = 2.4525 N

The string needs to sustain that force, therefore minimum Force that string has to be able to sustain is:
2.4525 N

The answer is 2.45 newtons because 1 kg = 9.8 newtons so when we use that ratio, we get around 2.45 newtons for 0.25 kg. This would be your (B) option I think.

A mole or fraction of a mole represents a _______number of atoms or molecules.a. specific
b. nonspecific

Can I get some help matching these from the left to the right?

1) increased surface area concentration decreases around solute
2) like polarity increases rate rate proportional to K.E.
3) temperature matching solvent and solute
4) stirring finely divided solute

Answers

A mole or fraction of a mole represents a nonspecific number of atoms or molecules. The answer is letter A.

The correct answer is number 2, like polarity increases rate rate proportional to K.E.

According to the information in your study unit, which of the following locations requires the highest illuminance? A. A residential stairway
B. A school locker room
C. A bank lobby
D. A study area

Answers

The correct answer is letter D. A study area. According to the information in your study unit, the location that requires the highest illuminance is the study room because it is the place the students can stay to study. The more brighter the place is, the more people are using that area.

Green light has a lower frequency than blue light. Which color of light has a longer wavelength?

Answers

Although green light has a lower frequency than the blue light, but green light has the longer wavelength than the wavelength of blue light. The wavelength of green light is longer by a small margin than the wavelength of the blue light. Red light has the highest wavelength among all the available colors of light. Any color of light is nothing but an electromagnetic wave that enables us to see things around us. Humans mostly can see wavelengths between the Electromagnetic spectrum and the Ultra violet region.
