**Answer:**** The work done on the object is 110 W**

**Explanation:**

**Work** is defined as the force that is causing the movement or displacement of an object.

**Mathematically,**

where,

W = work done on the object

F = Force applied on the object = 55 N

d = displacement = 10 m

**Putting values in above equation, we get:**

**Hence, the work done on the object is 110 W**

Solution 1

Na2SO4

Hoped this helped a little.

Hoped this helped a little.

Question

A wave is moving at the rate of 40 cm/s. Its wavelength is 8 cm. What is the frequency of the wave?

Solution 1

v=40 cms speed of wave

Î»=8 cm wavelength

f=? frequency of wave

v=Î»â f

40=8â f

f=408

f=5 sâ1Â is the answerQuestion

What does this graph show about the relationship between mass and acceleration? As acceleration increases, mass increases. As acceleration increases, mass is unaffected. As mass is unaffected, acceleration decreases. As mass increases, acceleration decreases.

Solution 1

Describe theÂ relationship betweenÂ net force andÂ accelerationÂ whenÂ mass isÂ held constant. TheÂ relationship isÂ directly proportional. This means when net force increases soÂ does acceleration. ... B.Â GraphÂ the line of Fn (net force) and A (acceleration).

Question

Sully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. The total mass of the snowmobile, including Sully, is 280 kilograms. If Sully accelerates to a velocity of 16 meters/second over 10 seconds, whatâs the force exerted by the snowmobile to accelerate? Use F = ma, where . 160 N 168 N 248 N 280 N 324 N

Solution 1

16 - 10 = 6

6 / 10 = .6 (this sign / means to divide)

F = 280 x .6 = 168

6 / 10 = .6 (this sign / means to divide)

F = 280 x .6 = 168

Solution 2

Answer: 168N

16 - 10 = 6

6 / 10 = .6

F = 280 x .6 = 168

16 - 10 = 6

6 / 10 = .6

F = 280 x .6 = 168

Question

If a bus travels 20 km in 30 minutes. What is the average speed of the bus? A.) 20km/h
B.) 30km/h
C.) 40km/h
D.) 50km/h

Solution 1

Question

Does the moon really change shape? Explain.

Solution 1

Wouldn't say it changes shape but it does look like it does but its because the moon spins around the sun which makes it turn to full moon, half moon, crescentsÂ but it is still a circle its just that the sun shapes it by the rotation.

Question

According to Charles's Law, if the pressure of a gas stays constant, when the temperature increases, the volume __________.

Solution 1

The correct answer is "the volume increases".

In fact, Charle's law states that when the pressure of a gas stays constant, the ratio between the temperature and the volume of the gas is constant:

where T is the gas temperature and V is its volume. We see from the formula that, if the temperature T increases, since the ratio must remain constant, the volume of the gas V increases as well.

The volume increases is right for apex

Question

The atomic mass is important because? a. it tells you the size of the atom
b. it tells you the charge of the atom
c. it tells you the number of electrons

Solution 1

A because mass is sizeÂ

Question

The atomic mass is important because? a. it tells you the size of the atom
b.it tells you the number of electrons

Solution 1

B is correct answer.

The atomic mass is the most important because it tells you the number of electrons.

Solution 2

B.it tells you the number of electrons

Question

Which type of heat transfer occurs through electromagnetic waves? A. insulation B. conduction C. radiation D. convection

Solution 1

Electromagnetic waves are often called "electromagnetic radiation".

That's a really strong clue.

Heat carried in the form of electromagnetic waves is

Solution 2

C is radiation

Convection is the transfer of heat by the flow of material (usually air or water)

Conduction is energy transferred when molecules bump into one another

Radiation is the answer

Convection is the transfer of heat by the flow of material (usually air or water)

Conduction is energy transferred when molecules bump into one another

Radiation is the answer
