Is there a link between number of bulbs and current drawn from the power pack?

Answers

Answer:

Yes, there a link between number of bulbs and current drawn from the power pack.

Explanation:

In an Electrical circuit, we have resistors present in that circuit. These resistors can be connected in two ways.

a) Series connection

b) Parallel connection

There is a link or a relationship between number of bulbs and the current drawn from the power pack. This is because the number of bulbs is equivalent to or equal to the number of resistors.

Hence,

a) In a series connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) decreases.

b) In a parallel connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) increases.

a motorcar is moving with a velocity of 108 km / h and it takes 4s to stop after the brakes are applied calculate the force exerted by the brakes on the motorcar if it's mass along with the passengers is 1000 kg​

Answers

Answer: - 7500N

Explanation:

Given the following :

Initial Velocity of car = 108km/hr

Time taken to stop after applying brakes = 4s

Mass of passengers in car = 1000kg

Force exerted by the brakes on the car =?

After 4s, then final Velocity (V) = 0

Initial Velocity (u) of the car = 108km/hr

108km/hr = (108 × 1000)m ÷ (3600)s = 30m/s

Force exerted = mass(m) × acceleration(a)

Acceleration of car = Change in Velocity with time

a = (v - u) / t

a = (0 - 30) / 4

a = - 30/ 4

a = - 7.5m/s^2

Therefore,

Force exerted = mass(m) × acceleration(a)

Force exerted = 1000kg × (-7.5)m/s^2

Force exerted = - 7500N

Answer:

The force exerted by the brakes on the motor car is -7500 N.

Explanation:

Given :-

Mass of the motor car along with passengers (m)= 1000 kgInitial velocity (u) = 108 km/hTime taken (t) = 4 s

To find :-

The force exerted by the brakes on the motor car.

Solution :-

Since the car stops, the final velocity (v) will be 0 m/s.

• Initial velocity (u) = 108 km/h.

Converting initial velocity into m/s.

We know that,[tex] \sf{1\:km/h=\dfrac{5}{18}\:m/s}[/tex]

Then initial velocity,

= [108 × 5/18 ] m/s

= 30 m/s

Now find the force exerted by the brakes.

Formula used :

[tex]{\boxed{\sf{F=\dfrac{m(v-u)}{t}}}}[/tex]

   [put values]

[tex]:\implies \sf \: F= \dfrac{1000(0 - 30)}{ 4} \\ \\ : \implies \sf \: F \: = \dfrac{ - 30000}{4} \\ \\ : \implies \sf \: F \: = - 7500[/tex]

The force exerted by the brakes on the motor car = -7500 N.

•The negative sign of force(F) means that the force was applied in opposite direction of motion.

b) Explain the method of preparing electromagnet. How do you test the
poles of an electromagnet with the help of magnetic compass ?

Answers

Answer:

An electromagnet is made by forming a coil around a soft iron bar (known here as the metal) such as a nail or  screw and connect with an insulated copper wire (known here as the electric current conductor) the ends of the wound copper is then connected separately to the positive and negative terminals of a battery (known here as the source of electric current)

The north seeking needle of the magnetic compass will move away when brought close to the north pole of the formed electromagnet which can then be labelled N

The magnetic compass needle will be attracted to the south pole of the electromagnet which can then be labelled S

Explanation:

An electromagnet is an electric powered magnet that is formed (temporarily) by the perpendicular movement of electric current with respect to a metal core

The magnitude and the poles of an electromagnet can be changed by changing the magnitude and the direction of flow of the electric current respectively.

A 2 kg billiard green ball is moving toward the 2 kg white billiard ball on a pool table. The green ball is moving with an initial speed of 4 m/s and the white ball is at rest. The two balls collide and move apart. The white ball moves away from the green ball with a speed of -6 m/s. With what speed does the green ball move away?

Answers

Answer:

10m/s

Explanation:

collisions results in objects sticking together or not sticking together after collision and so they do move with a common velocity or uncommon velocity respectively.

Parameters from the question:

Mass of green billiard balls, m1=2kg

Mass of white billiard balls, m2=2kg

Initial velocity for green billiard balls ,u1=4m/s

Initial velocity for white billiard balls ,u2 = 0m/s( since the body is at rest meaning it wasn't moving)

Final velocity of green billiard ball after collision is,v1= unknown

Final velocity of white green billiard ball after collision is, V2 = -6m/s.

Now from Newton's third law of motion that action and reaction must be equal and opposite;hence change in momentum before collision would be the same after collision since energy is conserved.

Hence,

m1U1 + m2U2 = m1V1 +m2V2

2×4 + 2×0 = 2×V1 + 2× (-6)

8 = 2V1 -12

8+12=2V1

20=2V1

10=V1

V1=10m/s

A car accelerates from 10m/s to 20m/s over a distance of 80m. What is its acceleration?

Answers

Answer:

0.125m/s^2

Explanation:

20-10=10

10 divided by 80=0.125m/s^2

The average velocity of the car is 15 m/s. The time taken to travel over the distance with this velocity is 5.3 seconds. Then the acceleration of the car is 1.8 m/s².

Wat is acceleration ?

Acceleration is a physical quantity measuring the rate  of change in velocity of a moving object. Like velocity, acceleration is a vector quantity having magnitude and direction.

Acceleration is the ratio of change in velocity to the change in time.

a = Δv/Δt

Given, the car is accelerating from 10 to 20 m/s. Hence, it travelled with average velocity of 15 m/s over the distance of 80 m.

Then , time taken  = distance/velocity

t = 80 m/15 m/s = 5.3 s

Acceleration = Δv/t = (20 -10 m/s) /5.3 s = 1.8 m/s².

Therefore, the acceleration of the car is about  1.8 m/s².

What is the magnitude of impulse of a 2.7 gram ping pong ball initially moving at 15 m/s, if hit by a ping pong paddle and then moves the opposite direction at 14/ms

Answers

Answer:

impulse = 0.0783 kg.m/s

Explanation:

The impulse is the product of the force and an interval of time. This can be represented in terms of the mass of the body and the change in the velocity of the body in such a time:

[tex]F\Delta t=m\Delta v[/tex] [tex]=|m(v_f-v_i)|[/tex]

m: mass of the body = 2.7gm = 0.0027 kg

vf: final velocity = -14m/s

vi: initial velocity = 15m/s

vf is negative because the direction of the ball is opposite to the initial direction:

[tex]|m(v_f-v_i)|=|(0.0027kg)(-14m/s-15m/s)|=0.0783\frac{kg.m}{s}[/tex]

hence, the impulse of the ping pong ball is 0.0783 kg.m/s

Q1: A step-up transformer has 80 turns on its primary coil and 1200 turns on its secondary coil. The
primary circuit is supplied with an alternating current at 120 V.
a) What voltage is being applied across the secondary circuit?
b) The current in the secondary circuit is 2.0 A. What current is in the primary circuit?
c) What are the power input and output of the transformer?

Answers

Answer:

a. 1.8 kV b. 30 A c. power input = 3.6 kW, power output = 3.6 kW

Explanation:

a. Since turns ratio N₁/N₂  = V₁/V₂ where N₁ = number of turns of primary coil = 80 turns, N₂ = number of turns of secondary coil = 1200 turns, V₁ = voltage in primary circuit = 120 V and V₂ = voltage in secondary circuit = unknown

So, V₂ = N₂V₁/N₁

= 1200 × 120 V/80

= 1800 V

= 1.8 kV

b. Also, N₁/N₂ = I₂/I₁ where I₁ = current in primary circuit = unknown and I₂ =  current in secondary circuit = 2.0 A

So, I₁ = N₂I₂/N₁

= 1200 × 2.0 A/80

= 30 A

c. The power input of the transformer P₁ = I₁V₁

= 30 A × 120 V

= 3600 W

= 3.6 kW

The power output of the transformer P₂ = I₂V₂

= 2 A × 1800 V

= 3600 W

= 3.6 kW

a) The voltage applied across the secondary circuit is 1.8 kV

b) The current in the primary circuit is  30 A

c) The power input and output of the transformer are 3.6 kW and 3.6 kW.

What is transformer?

A transformer transfers electric energy from one AC circuit to one or more other circuits, either stepping up or stepping down the voltage.

a)  Turns ratio N₁/N₂  = V₁/V₂ where N₁ = number of turns of primary coil = 80 turns, N₂ = number of turns of secondary coil = 1200 turns, V₁ = voltage in primary circuit = 120 V

Substitute the values and we get the voltage in secondary circuit is

V₂ = N₂V₁/N₁

V₂ = 1200 × 120 V/80

V₂ = 1800 V

V₂ = 1.8 kV

Thus, the voltage applied across the secondary circuit is 1.8 kV

b) Turn ratio also represented as  N₁/N₂ = I₂/I₁ where  I₂ is the current in secondary circuit = 2.0 A
Put the values, we have current in primary circuit is

I₁ = N₂I₂/N₁

I₁ = 1200 × 2.0 A/80

I₁ = 30 A

Thus, the current in the primary circuit is  30 A

c) The power input of the transformer P₁ = I₁V₁

P₁ = 30 A × 120 V

P₁ = 3600 W

P₁ = 3.6 kW

The power output of the transformer P₂ = I₂V₂

P₂= 2 A × 1800 V

P₂= 3600 W

P₂= 3.6 kW

The power input and output of the transformer are 3.6 kW and 3.6 kW.
