An electron is moving in a circular orbit in a uniform magnetic field. Is the kinetic energy of the electron changing? select the correct answer and explanation.

Answers

Answer 1

No, the kinetic energy of the electron will not change.

The relationship of electron moving in a circular orbit in a uniform magnetic field:

The electron receives no work from the magnetic force. In actuality, the magnetic force's work is provided by:

where F is the magnetic force, d is the electron's displacement, and is the angle between the force's direction and the electron's motion.

However, because the magnetic pull is always perpendicular to the charged particle's direction and velocity, there is no work done.

The work-energy theorem states that the change in an electron's kinetic energy is equal to the work that has been done on it; therefore, because there has been no work done, the electron's kinetic energy has not changed.

How high would a skater need to start on a previous incline to make it up and around a loop that is 6.1meters high?

Answers

The skater need to start 7.525 meter high.

Let,

The skater need to start on a previous incline at height = h.

Mass of the skater = m

Given, height of the loop = 6.1 meter.

Radius of the loop; r = 6.1/2 meter = 3.05 meter.

Let to make it up and around a loop that is 6.1meters high, the man required minimum velocity v on the highest point of the loop.

So, centripetal force at highest point = weight of the man

⇒ mv²/r = mg

⇒ v = √(gr)

Then, potential energy of the skater at height h is = mgh.

And, minimum energy  of the skater at the highest point of the loop is = potential energy + minimum kinetic energy.

= mg(2r) + 1/2 mv²

= 2mgr + 1/2 mgr

= 5/2 mgr

According to conservation of energy,

potential energy of the skater at height h = minimum energy  of the skater at the highest point of the loop

⇒ mgh = 5/2 mgr

⇒ h = 5/2 r =( 5/2 )× 3.05 meter = 7.525 meter.

Hence, required height is 7.525 meter.

a 45.0-kg woman stands up in a 60.0-kg canoe 5.0 m long. she walks from a point 1.00 m from one end to a point 1.00 m from the other end. if you ignore resistance to motion of the canoe in the water, how far does the canoe move during this process?

Answers

Answer:

Measure the CM from the left end of the canoe

M x = (45 * 1 + 2.5 * 60)      M = 105

x = (45 + 150) / 105 = 1.86 m         from left end

After she walks 3 m the CM is from the left end

M y = (45 * 4 + 60 * 2.5)

y = (45 * 4 + 60 * 2.5) / 105 = 3.14 m

The left end of the canoe has moved 1.28 m to left

(The CM cannot move without an external force)

Check:

She increases the CM by 45 (3 - 1.28) = 77.4

Canoe movement decreases the CM by 60 * 1.28 = 76.8

1.28 is close

A 2 kg toy caramels at a speed of 5 m/s if a child applies a three new enforce for 2 m in the same direction the car is already moving how much work is done on the car

Answers

The work done on the car is equal to the force applied to the car multiplied by the distance over which that force is applied. In this case, the force is applied for 2 meters, so the work done is equal to 3 Newtons multiplied by 2 meters, or 6 Joules.

What is force?
A force is indeed an influence that can alter an object's motion in physics. An object with mass can change its velocity, or accelerate, as a result of a force. An intuitive way to describe force is as a push or even a pull. A force is a vector quantity because it has both direction and magnitude. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P). The net force acting on an object seems to be equal to the rate that its momentum changes over time, according to Newton's second law in its original formulation. This law suggests that an object's acceleration is directly proportional to the total force acting on the object if the object's mass remains constant.

Work is defined as force multiplied by distance, so the work done on the car is (3 N)(2 m) = 6 Nm. Since 1 Nm = 1 J, the work done on the car is 6 J.

Answers

The velocity of the bullet is  1100 m/s.

When the bullet lodges into the block, as there is no net external force, the momentum of the system will be conserved. After that when the block + bullet system compresses the spring, the energy of the system remains conserved. The kinetic energy is conserved into the potential energy of the spring.

Velocity is the directional speed of an object in movement as an illustration of its price of the trade-in position as found from a particular frame of reference and as measured through a specific standard of time.

Calculation:-

Mass of block, M = 4 Kg

Mass of bullet, m = 8 g = 0.008 Kg

Compression in spring, x = 8.7cm = 0.087 m

An orbital is a region where it is possible to estimate the likelihood of finding any electron, whereas an orbit is a fixed path that electrons follow around the atom's nucleus.

The Kuiper Belt is thought to contain a trillion comets or more and hundreds of thousands of icy bodies bigger than 100 km (62 miles).

Therefore, there may be hundreds of thousands of icy bodies larger than 100 km have been observed to be orbiting in the Kuiper belt is approximately.

A ball is pushed downhill with an initial velocity of 3. 0 m/s. The ball rolls down a hill with a constant acceleration of 1. 6 m/s2. The ball reaches the bottom of the hill in 6. 0 s. What is the ball's velocity at the bottom of the hill?.

Answers

The ball's velocity at the bottom of the hill is 12.6 m/s. The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar quantity.

Velocity can be defined as the rate at which something moves in a specific direction. as the speed of a car driving north on a highway or the pace at which a rocket takes off. Because the velocity vector is scalar, its absolute value magnitude will always equal the motion's speed. Additionally, it is inversely proportional to transit duration and proportionate to displacement. Its measurement is in meters per second (m/s). The velocity formula is shown below: V = s/t.

Where V is the end velocity, u the beginning velocity, a the acceleration, and t the duration,

We obtain the response by substituting the data. 12.6 m/s.

cables provide most of the support to keep a suspension bridge up. the elastic force of tension pulling u is 28,000 N and the force of gravity is 28,000 N down. find the net force

Answers

The net force to keep a suspension bridge up is zero, 0N.

An action-reaction pair of forces acting at each end of the aforementioned elements is tension. Consider a rope. Aside from the ends, every portion of the rope experiences tension force in both directions. The attached weight exerts force and tension on one side of the ends. The tension of the string fluctuates under different conditions. The net force formula is provided by when the body is at rest.

The tension exerted on an item is determined by adding the products of its mass, acceleration, and gravitational force. It is denoted mathematically as follows:

T = mg + ma

Where,

T is tension

m is mass

a is acceleration

g is the acceleration due to gravity

Here,

T = 28000N

mg = 28000N

ma = T - mg

ma = 28000 - 28000

ma = 0N

The net force to keep a suspension bridge up is zero, 0N.

*IN JAVA*Program Specifications Write a program to calculate U.S. income tax owed given wages, taxable interest, unemployment compensation, status (dependent, single, or married), and taxes withheld. Dollar amounts are displayed as integers with comma separators. Ex: System.out.printf("Cost: $%,d\n", cost);Note: this program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress.Step 1. Within main() input wages, taxable interest, unemployment compensation, status (0=dependent, 1=single, and 2=married), and taxes withheld as integers.Step 2 (2 pts). Complete the calcAGI() method. Calculate the adjusted gross income (AGI) that is the sum of wages, interest, and unemployment. Convert any negative values to positive before summing to correct potential input errors. Return the AGI. Note the provided code in main() calls calcAGI() and outputs the returned value. Submit for grading to confirm two tests pass.Ex: If the input is:20000 23 500 1 400The output is:AGI: $20,523Step 3 (2 pts). Complete the getDeduction() method. Return the deduction amount based on status: (0) dependent = 6000, (1) single = 12000, or (2) married=24000. Return 6000 if the status is anything but 0, 1, or 2. Within main() call getDeduction() and output the returned value.
