What is the length of an aluminum rod at 65°C if its length at 15°C is 1.2 meters?

Answers

Answer 1
Answer:

Answer:

The new length is 1.20138 m

Explanation:

1- We get the increase in length:

The old length = 1.2 m

The coefficient of expansion of of aluminum is 23 * 10⁻⁶ /K.

The old temperature is 15°C.

The new temperature is 65°C

The increase in length= old length * coefficient of expansion *change in temperature

The increase in length = 1.2 * 23 * 10⁻⁶ * (65-15)

The increase in length = 0.00138 m

2- getting the new length:

new length = old length + increase in length

new length = 1.2 + 0.00138

new length = 1.20138 m

Hope this helps :)

Discuss the force that exists between the Earth and the moon by referring to the mass of each.

Answers

The word gravity is used to describe the gravitational pull (force) an object experiences on or near the surface of a planet or moon. The gravitational force is a force that attracts objects with mass towards each other. Any object with mass exerts a gravitational force on any other object with mass.

Gravity causes___ objects to accelerate

Answers

Gravity causes falling objects to accelerate.
all? 

Most likely all.

The reason is since the acceleration of gravity is about 10 m/s^2 this means that gravity would cause all objects to accelerate at the same rate. So most likely all objects.

(c)The marble acquires a positive charge and repels the piece of silk. (d)The marble acquires a positive charge and attracts the piece of silk. (e)The marble acquires a negative charge and attracts the piece of silk. (f)The marble acquires a negative charge and repels the piece of silk. There may be more than one answer.

Answers

The right answer for the question that is being asked and shown above is that: "(b)The marble has acquired the same number of electrons acquired by the piece of silk; (f)The marble acquires a negative charge and repels the piece of silk."

What is one disadvantage of a series circuit?A. The bulbs in a series circuit will give off more heat then the same bulbs in a parallel circuit.
B. If one bulb burns out, then none of the others will light up.
C. It is difficult to tell which path an electric charge is following in a series circuit
D. Only one bulb can be connected in a series circuit.

Answers

If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺
