 μ = 0.49

Explanation:

For this exercise we can use Newton's second law

Y Axis

       N - W = 0

       N = W = mg

X axis

       -fr = ma

the equation for the friction force is

        fr = μ N

we substitute

       -μ  m g = ma

        μ = -a / g

we calculate

      μ = 4.8 / 9.8

      μ = 0.49

Explanation:

Shuffling your feet across the floor as you walk is an example of charging by friction. The correct option is A.

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.

There are various kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.

Frictional force is the force produced when two surfaces slide against and touch each other.

The surface texture and amount of force needing them together have the biggest an impact on these forces. The amount of frictional force is influenced by the object's position and angle.

As an illustration of how charge is transferred via friction, consider walking over a carpet.

Thus, the correct option is A.

Answer:

The equivalent resistance of the combination is R/100

Explanation:

Electric Resistance

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]

If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}[/tex]

This sum is repeated 10 times. Operating each term:

[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]

All the terms have the same denominator, thus:

[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]

Taking the reciprocals:

[tex]R_e=R/100[/tex]

The equivalent resistance of the combination is R/100

Answer:

The body becomes a positive charged body.

Explanation:

Given that two objects are shown below. One is neutral and the other is negative. What do you predict would happen?

According to the law of static electricity, like charges repel each other while unlike charges attract each other.

Since one of the object is neutral and the other one is negative, there will neither attraction nor repulsion between them.

Also, according to Electrostatic induction, the neural body can be charged and becomes positive.

The negative body will attract all the positive charges to its side, and repel all the negative charges to the other side. If the body is touched at the other end, the whole negative charges will be earthed and the body will become a positive body.

Answer:

29.4m/s

Explanation:

Given parameters:

Time  = 3s

Unknown:

Average velocity  = ?

Solution:

To solve this problem, we use the expression below:

      v  = u + gt

v is the average velocity

u is the initial velocity  = 0m/s

g is the acceleration due to gravity  = 9.8m/s²

t is the time

So;

        v  = 0 + (9.8 x 3)  = 29.4m/s

Answer:

A table of motion (for a moving object) usually is something like:

Time I Position:

0s           1m

1s            3m

2s           5m

etc...

Where time is the independent variable and position represents the position of the object at that given time.

We can think in these points as coordinate pairs, for example, we can wrote these 3 pairs as:

(0s, 1m)

(1s, 3m)

(2s, 5m)

Now that we have these points, we can go to a coordinate plane and find these points

(The time would be on the horizontal axis, and position in the vertical axis)

Once you found the points, to complete the graph you need to find a line that connects the points.

An example of this is shown below, where the points used are the ones above, and the line should be straight.

Answer:

vB' = 0.075[m/s]

Explanation:

We can solve this problem using the principle of linear momentum conservation, which tells us that momentum is preserved before and after the collision.

Now we have to come up with an equation that involves both bodies, before and after the collision. To the left of the equal sign are taken the bodies before the collision and to the right after the collision.

[tex](m_{A}*v_{A})+(m_{B}*v_{B})=(m_{A}*v_{A'})+(m_{B}*v_{B'})[/tex]

where:

mA = 0.355 [kg]

vA = 0.095 [m/s] before the collision

mB = 0.710 [kg]

vB = 0.045 [m/s] before the collision

vA' = 0.035 [m/s] after the collision

vB' [m/s] after the collison.

The signs in the equation remain positive since before and after the collision, both bodies continue to move in the same direction.

[tex](0.355*0.095)+(0.710*0.045)=(0.355*0.035)+(0.710*v_{B'})\\v_{B'}=0.075[m/s][/tex]

Answer:

2

Explanation:

Due to the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn together by a stronger gravitational attraction. As a result, the gravitational pull between two objects grows as their respective masses rise.

Since the gravitational force is exactly proportional to the mass of both interacting objects, heavier items will be attracted by stronger gravitational forces. Therefore, the gravitational attraction between two objects grows as their respective masses do as well.

The attraction created by gravity is between masses. The gravitational force, commonly known as the gravity force, increases with the size of the masses. With an increase in the distance between masses, the gravitational pull rapidly lessens.

Therefore, second have greater gravitational force.

Answer :

Label A - nucleus.

Label B- electron cloud.

Explanation :

An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.

The electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

In the picture, label A shows the nucleus.

Electrons has the ability to revolve around the nucleus in a fixed circular orbit. Electron cloud represents the spreading of the electrons energy.

In the picture, label B shows the electron cloud.

Hence, the label A - nucleus and label B- electron cloud.

40 ampere current passes through a 1 kW heater with 25 Voltage across it.

The difference in electric potential between two places is known as voltage, often referred to as electric pressure, electric tension, or potential difference. It relates to the amount of labor required to transfer a test charge between two places in a static electric field.

Given that power of the source is 1 kW and voltage is 25 V

current is given as,

Power = Voltage*Current

1kW = 25*Current

Current = 1000/25 = 40 ampere.

40 ampere current passes through a 1 kW heater with 25 Voltage across it.

A rocket ship starts from rest and turns on its forward booster rockets, causing it to have a constant acceleration of 4 m/s² rightward. After 3s, what will be the velocity of the rocket ship?

Answer:

v = 12 m/s

Explanation:

We are given;

Initial velocity; u = 0 m/s (because ship starts from rest)

Acceleration; a = 4 m/s²

Time; t = 3 s

To find velocity after 3 s, we will use Newton's first equation of motion;

v = u + at

v = 0 + (4 × 3)

v = 12 m/s
