A bus moves with 500000joules the driver applies brakes how much work is needed for the bus to stop

Answers

The bus is moving and its initial kinetic energy is
[tex]K_i=500000J=5 \cdot 10^5 J[/tex]

We want the bus to stop, so that its final kinetic energy is zero:
[tex]K_f = 0[/tex]

The work-energy theorem states that the work done by an object is equal to its variation of kinetic energy:
[tex]W=K_f - K_i[/tex]
Therefore:
[tex]W=0-5 \cdot 10^5 J = -5 \cdot 10^5 J[/tex]
This is the amount of work that needs to be done in order to stop the bus, and its sign is negative because the force applied (the force of the brakes) is opposite to the direction of motion of the bus.

When the north pole of a bar magnet is moved into a solenoid, the needle on a galvanometer attached to the solenoid moves to the left, indicating that a current is produced. the magnet is then pulled out at a faster speed.what will be the result?a larger current in the same directiona larger current in the opposite directiona smaller current in the same directiona smaller current in the opposite direction?

Answers

answer BBBBBBBBBBBB on EDGE

Answer:

a larger current in the opposite direction

Explanation:

As we know by Faraday's law of electromagnetic induction that rate of change in magnetic flux will induce electric current in a conducting coil linked with it

so it is given as

[tex]EMF = \frac{d\phi}{dt}[/tex]

now in this situation we know that first a magnet is entering into the coil so here the magnetic flux is increasing linked with the solenoid coil.

So it will induce some current in the coil which shows deflection in galvanometer coil.

Now when we pull the magnet out then it will decrease the flux linked with the coil so here the direction of induced current must have to decrease.

Also it is given that coil is removed at faster rate due to which the rate of change in flux will be more so here it will induce more current

so correct answer would be

a larger current in the opposite direction

Have a great day!!

Final answer:

A skydiver in free fall describes constant acceleration in one direction since gravity provides a constant acceleration downwards near Earth's surface.

Explanation:

The question asks which scenario describes constant acceleration in one direction. The correct answer is a skydiver in free fall. This is because, near the surface of the Earth, an object in free fall experiences a constant acceleration due to gravity, with a magnitude of approximately 9.8 m/s².

The direction of this acceleration is vertically downwards, and it remains constant in both magnitude and direction in the absence of air resistance.

In contrast, a car rounding a bend, a merry-go-round increasing speed, or a pendulum swinging all experience changing directions or types of motion which do not represent constant acceleration in one direction.

According to charles' law, the volume of a fixed amount of gas is directly proportional to

Answers

Final answer:

According to Charles's law, the volume of a fixed amount of gas is directly proportional to its Kelvin temperature, assuming constant pressure. It means that volume of the gas increases with increase in temperature and decreases with decrease in temperature.

Explanation:

According to Charles's law, the volume of a fixed amount of gas is directly proportional to its Kelvin temperature when the pressure is held constant. This law was named after the French scientist Jacques Alexandre César Charles, a pioneer in balloon flight. It essentially means that when the temperature of gas increases under constant pressure, the volume of the gas also increases and vice versa.

For instance, if you raise the gas temperature from 283 K to 303 K at a constant pressure, you will see an increase in its volume from 0.300 L to 0.321 L, corroborating Charles's law.

what is the difference between series and parallel circuits and examples of when you would use them ?

Answers

Difference between series and parallel circuits:

In circuits, two or more elements are in series if they exclusively share a single node and consequently carry the same current. On the other hand, two or more elements are in parallel if they are connected to the same two nodes and consequently have the same voltage across them.

We know that a node is the point of connection between two or more branches and a branch represents a single element such as a voltage source or a resistor or other elements.

In the figures below there are the representations of this type of circuits.

Example of when I would use them:

*Lighting systems, such as in a house or on a Christmas tree, often consistof N lamps connected either in parallel or in series,

*These type of circuits find continual applications in electronics, communications, and control systems.

*Lawnmowers have two switches in series with each other. Therefore, both switches need to be pressed before the mower will turn on.

How does a gas do work?

A. By changing volume
B. By creating energy
C. By conserving energy
D. By flowing

Answers

A gas does work by changing its volume, adhering to the law of conservation of energy and resulting in increases in energy, pressure, and/or temperature.

A gas can do work by changing its volume. When a gas in a cylinder expands, it exerts a force on the piston and moves it, doing work. According to the Ideal Gas Law, work done by a gas results in an increase in its energy, which can manifest as an increased internal kinetic energy due to the motion of its atoms and molecules. This concept adheres to the law of conservation of energy, meaning that energy within a closed system is neither created nor destroyed, but can change forms. An example of work being done by a gas is when you inflate a bicycle tire; the air pressure and temperature increase inside the tire due to the work done by the pump.

Thus, the correct answer to how a gas does work is A. By changing volume.

A car turns a corner that has a radius of 5 m and experiences a centripetal acceleration of 20 m/s². If the radius of turn were increased to 10 m, calculate the centripetal acceleration.

Answers

The centripetal acceleration is given by:

v is the velocity of the object
r is the radius of the trajectory

Initially, the car has an acceleration of [tex]a_c = 20 m/s^2[/tex] and the radius of its trajectory is [tex]r=5 m[/tex], so its velocity is
[tex]v= \sqrt{a_c r}= \sqrt{(20 m/s^2)(5 m)} =10 m/s [/tex]

Then the radius is increased to r=10 m, so the new centripetal acceleration is:

Buffers contains both acids and bases in equilibrium.when base is added to buffers, they adjust the pH value by releasing hydrogen ions.when acid is added to buffers, they adjust the pH value by consuming hydrogen ions. hence these substances resist any change in their pH value by releasing or absorbing hydrogen ions.This process keeps the pH value constant.

A sound from a source has an intensity of 270 dB when it is 1 m from the source.


What is the intensity of the sound when it is 3 m from the source?

30 dB
90 dB
810 dB
2430 dB

Answers

Remember that sound intensity decreases in inverse proportion to the distance squared. So, to solve this we are going to use the inverse square formula: [tex] \frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2 [/tex]
where
[tex]I_{2}[/tex] is the intensity at distance 2
[tex]I_{1}[/tex] is the intensity at distance 1
[tex]d_{2}[/tex] is distance 2
[tex]d_{1}[/tex] is distance 1

We can infer for our problem that [tex]I_{1}=270[/tex], [tex]d_{1}=1[/tex], and [tex]d_{2}=3[/tex]. Lets replace those values in our formula to find [tex]I_{2}[/tex]:
[tex] \frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2 [/tex]
[tex] \frac{I_{2} }{270} =( \frac{1}{3} )^2[/tex]
[tex]\frac{I_{2} }{270} = \frac{1}{9} [/tex]
[tex]I_{2}= \frac{270}{9} [/tex]
[tex]I_{2}=30[/tex] dB

We can conclude that the intensity of the sound when is 3 m from the source is 30 dB.

Which of the following would decrease the magnetic field around a wire?
A. decreasing the current
B. reversing the poles of the wire
C. looping a section of the wire into a solenoid
D. increasing the current

Answers

The correct answer is
A. decreasing the current

In fact, the magnetic field produced by a current carrying wire is given by
[tex]B(r) = \frac{\mu_0 I}{2 \pi r} [/tex]
where
[tex]\mu_0 [/tex] is the vacuum permeability
I is the current in the wire
r is the distance from the wire at which the field is calculated

We see from the formula that the intensity of the field, B, is directly proportional to the current I, so if the current decreases, the magnetic field strength B decreases as well.

C) A positive charge crosses an equipotential line toward the source charge.
D) A positive charge moves along an equipotential line.

UPDATE: ANSWER IS C

Answers

The correct answer is: Option (C) A positive charge crosses an equipotential line toward the source charge.

Explanation:
The red circles drawn are the equipotential circles. It means that on the line of the circle the work that YOU have done from bringing the positive test charge from infinity to every point on the line of the circle is same. Imagine you are moving towards the source charge from very far away. The more you move towards the source charge the more you will experience the force on you due to the increasing electric field near the charge and the more POSITIVE work you do. It means the work increases and in Electromagnetism that work is translated as the voltage. Hence a positive charge crosses an equipotential line toward the source charge with the increase in voltage. Therefore the correct option is (C).

A radioactive sample has a count rate of 800 counts per minute. One hour later, the count rate has fallen to 100 counts per minute. What is the half-life of the sample?

Answers

Radioactivity equation states:

N = No e^(-0.693t/t1/2) --- Where t = time, t1/2 = half-life, N = count after time t, No = Initial count

Using the values given;

100 = 800 e^(-0.693*1/t1/2)
100/800 = e^(-0.693t/t1/2)
0.125 = e^(-0.693/t1/2)
Taking natural logs on both sides;
log 0.125 = -0.693/t1/2 * log (e)
-0.9031 = -0.693/t1/2 * 0.4323
t1/2 = (-0.693*0.4323)/(-0.9031) = 0.3317 hours

The image shows a pendulum that is released from rest at point A. Which energy transformation is correct? From A to C, kinetic energy is transformed into gravitational potential energy. From C to D, kinetic energy is transformed into gravitational potential energy. From C to E, gravitational potential energy is transformed into kinetic energy. From D to E, gravitational potential energy is transformed into kinetic energy.

Answers

Answer:

Partially: From C to D, kinetic energy is transformed into gravitational potential energy and From D to E, gravitational potential energy is transformed into kinetic energy

Explanation:

What happens in this pendulum is that at point A, there's only gravitational potential energy (no velocity=no kinetic energy)

At point C, it has maximum speed since all of the potential energy is transformed into kinetic energy (no potential gravitational  energy at this point)

At point E, it is the same as at point A. (no kinetic energy)

At the intermediate points (B and D) there are both kinetic and potential energy. At point B the kinetic energy is increasing and at point D it is decreasing.

Now let's see each case:

- From A to C, kinetic energy is transformed into gravitational potential energy: It is actually the opposite, so no.

- From C to D, kinetic energy is transformed into gravitational potential energy: Yes, but not all of it is transformed since it still has kinetic energy that allows it to get til point E.

- From C to E, gravitational potential energy is transformed into kinetic energy: No, it is the opposite.

- From D to E, gravitational potential energy is transformed into kinetic energy: Yes, but not all of it, since at point D it also has kinetic energy.

The kinetic energy is transformed into gravitational potential energy from point C to B. But complete transformation is not happening. Thus, the statement is somehow correct.

The analysis of pendulum is given as follows:

At point A, there's only gravitational potential energy and no kinetic energy, because the pendulum is at rest at A.   At point C, it has maximum speed since all of the potential energy is transformed into kinetic energy. Therefore, at this point there is only kinetic energy and no potential energy. At point E, it is the same as at point A, but in opposite side. So, at this point there is no kinetic energy. At  points B and D there are both kinetic and potential energy. At point B the kinetic energy is increasing and at point D it is decreasing.

Now as per the given statements:  

From A to C, kinetic energy is transformed into gravitational potential energy.  It is actually the opposite. Thus, the statement is incorrect. From C to D, kinetic energy is transformed into gravitational potential energy. At this interval, the kinetic energy is converting into potential energy but the conversion is not complete. Thus, the statement is somehow correct. From C to E, gravitational potential energy is transformed into kinetic energy. At this point, the kinetic energy is converting into the potential energy. Thus, the statement is incorrect. From D to E, gravitational potential energy is transformed into kinetic energy. This statement incorrect because there is conversion of kinetic energy into potential energy.

Thus, we can conclude that from C to D, the kinetic energy is transformed into gravitational potential energy, but the transformation is not complete. Hence, statement (B) is correct.

What is the correct current value if the selector is in the 0.5 dcma position?

Answers

Final answer:

The correct current value is 1.35 A.

Explanation:

The correct current value in the 0.5 dcma position can be determined using the given information. According to the information provided in the question, after 5.00 ms, the current declines to 0.368 of the initial value at t=0. Therefore, we can find the initial value of the current by dividing the value at t=5.00 ms by 0.368. Let's calculate:

Initial current = (0.368)(3.68 A) = 1.35 A

So, the correct current value if the selector is in the 0.5 dcma position is 1.35 A.

A 72 kg sled Is pulled forward from rest by a snowmobile and accelerates at 2 m/s squared forward for five seconds. The force of friction acting on the sled is 120 N backwards. The total mass of the snowmobile and driver is 450 kg. The drag force acting on the snowmobile is 540 N backwards. What is the tension in the rope.

Answers

Final answer:

The tension in the rope is 516 N.

Explanation:

To find the tension in the rope, we need to calculate the net force acting on the sled. The net force is equal to the mass of the sled multiplied by its acceleration. Given that the sled has a mass of 72 kg and accelerates at 2 m/s² for 5 seconds, we can use the equation:

Net force = mass x acceleration

Net force = 72 kg x 2 m/s² = 144 N

However, there are two forces acting in the opposite direction - the force of friction (120 N backwards) and the drag force (540 N backwards). So, the net force is:

Net force = 144 N - 120 N - 540 N = -516 N

The negative sign indicates that the net force is acting in the opposite direction of motion. Therefore, the tension in the rope is equal in magnitude and opposite in direction to the net force, so the tension in the rope is 516 N.
