Conductivity in metallic solids is due to the presence of free

Answers

Answer:

due to the presence of fee electrons.

Explanation:

these electrons conduct electric current.

Conductivity in metallic solids is due to the presence of free electron. No of the electron will decide the flow of the electric current.

What is the charge?

When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.

Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term “neutral” refers to an item that has no net charge.

A valence electron is an electron in the outermost shell. Hence, associated with an atom that can experience the innovation of a chemical bond if the outer shell is not closed.

Conductivity in metallic solids is due to the presence of free electron.

Hence, electron is the correct answer for blank.

Answers

Answer:

friction

Explanation:

The property of matter that resists changes in motion is called friction. Details about friction can be found below.

What is friction?

Friction is a force that resists the relative motion of two bodies in contact.

Friction is a resisting force that is experienced when two bodies are moving over one another, hence, is said to resist changes in motion. Examples of cases of friction are as follows:

Vehicle moving over a tarred roadSliding of both hands over one another

Therefore, the property of matter that resists changes in motion is called friction.

Describe the mechanical energy and the thermal energy of a bouncing basketball

Answers

Answer:

when the ball is bounced gravitationally energy is released (more info below)

Explanation:

When a force is applied down to the ball, the gravitational potential energy is converted into kinetic energy before it hits the earth. Cinetic energy is converted into vibration, thermal, and static electrical energy, before the momentum of the ball pushes the ball back up into the hands of the people.

A car starts 10 m north of a reference point. It moves at a constant velocity over the next 5 s, reaching a position of 10 m south of the reference point.


What is the car’s average velocity?


2 m/s south

0 m/s

4 m/s south

4 m/s north

Answers

Answer:

v_avg = 4 m/s

Explanation:

The average velocity of the car is given by the distance traveled by the car, in a specific time.

The total distance is 20m, because the car moved to the reference point (10m), and then moves to 10m to the south. THe total distance is 20m.

Then, you use the following formula:

[tex]v_{avg}=\frac{x_t}{t}[/tex]

x_t: total distance traveled by the car =  20m

t: time in which the car made the trajectory =  5s

You replace the values of x_t and t:

[tex]v_{avg}=\frac{20m}{5s}=4\frac{m}{s}[/tex]

hence, the average velocity is 4m/s

1. If a soldier lifts a 2-kg counterweight 0.5 meters, what is the gravitational force of the counterweight? (Include the equation and appropriate units.)


2. If a soldier lifts a 2-kg counterweight 0.5 meters, how much work is done? (Include the equation and appropriate units.)


please please please please help!!!

Answers

Answer:

the gravitational force of the counterweight is 19.6 Nthe work done is 9.8 J

Explanation:

Question 1:

Given;

a counterweight of mass, m = 2-kg

distance moved by this weight, d = 0.5 meters

the gravitational force of the counterweight is calculated as;

F = mg

where;

F is gravitational force

m is the mass

g is acceleration due to gravity

F = 2 x 9.8 = 19.6 N

Thus, the gravitational force of the counterweight is 19.6 N

Question 2:

Given;

a counterweight of mass, m = 2-kg

height moved by this weight, h = 0.5 meters

the work done is calculated as;

Work done = Force x distance moved by this weight

Work done = 19.6 x 0.5 = 9.8 J

Thus, the work done is 9.8 J

It is 52° below the celestial equator. It is 52° to the left of the celestial equator. It is 52° to the right of the celestial equator.

Answers

Answer:

It is 52° below the celestial equator.

Explanation:

The declination is the angle in degrees measured north (+) or south (-) of the an imaginary line called the celestial equator.

The celestial equator is a projection of the earth's equator on the celestial sphere. imaginary

The star named Canopus has a declination of approximately –52°.

Since the angle is negative, this shows that it is south or below the celestial equator and at 52° south of the celestial equator.

Thus, the star named Caponus is 52° below the celestial equator.

Answers

Explanation:

It is given that, a robot starts from a certain point and moves east for a distance of 5.0 meters, then goes north for 3.0 meters, and then turns west for 2.0 meters.

Let east is +x, west is -x north is +y.

When it moves east for a distance of 5.0 meters, it means (5,0)

When it goes north for 3.0 meters, and then turns west for 2.0 meters, it means (0,3) +(-2,0)

An astronaut is on a new planet. She discovers that is she drops a space rock from 12m above the groundnut has a final velocity of 3m/s just before it strikes the planet surface. What is the acceleration due to gravity on the planet?

Answers

Answer:

-0.375 m/s2

Explanation:

To find the acceleration due to gravity in this planet, we can use the Torricelli formula of UALM (uniformly accelerated linear motion):

V^2 = Vo^2 + 2*a*S

Where V is the final velocity, Vo is the inicial velocity, a is the acceleration and S is the total displacement.

With V = 3, Vo = 0 and S = -12, we have:

3^2 = 0^2 - 2*a*12

24a = -9

a = -9/24 = -0.375 m/s2
