A twenty-acre park was created to give residents a place to hike, bike, and enjoy other recreational activities. Kathy was hired

to design a map that would show residents how they could easily access different areas of the park. Sean was hired to monitor the number of visitors they have per month and analyze the park’s popularity for funding possibilities. Joan was hired to offer assistance and teach residents about the plants and animals they may encounter while at the park.
Which best describes the tasks Kathy, Sean, and Joan perform?

Kathy and Joan perform tasks common to the Engineering and Technology pathway and Sean performs tasks common to the Science and Math pathway.

An electron traveling at a velocity v enters a uniform magnetic field B. Initially, the velocity and field are perpendicular to
Brut [27]

If the electron goes a distance d, the amount of work done on it by the magnetic field is zero.

Because magnetic force acts perpendicular to the direction of motion, it has no effect on any moving charge particle. As a result, speed won't change.

<h3>What is Magnetic field?</h3>
  • The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.
  • A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
  • A compass, a motor, the magnets that hold items in refrigerators, railroad tracks, and modern roller coasters are examples of devices that use magnetic force.
  • A magnetic field is created by all moving charges, and any charges that move across its regions are subject to a force.

Helen [10]

Complete Question

Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.

          pV=nRT

so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant

What is the \triangle U as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T

Answer:

\triangle T=0

\triangle V=0

The gas A and B have same internal energy

Explanation:

From the question we are told that

Pa=u atm\\Va=1m^3\\Pb=1 atm\\Vb=4m^3

Generally the equation of temperature is mathematically given as

Ta=\frac{Pv}{nR}

Ta=\frac{u*1}{nR}

And

Tb=\frac{PbVb}{nR}

Tb=\frac{u*1}{nR}

Generally the change in temperature \triangle T is mathematically given as

\triangle T=Tb-Ta=Tb=\frac{u*1}{nR}-\frac{u*1}{nR}

\triangle T=0

Generally the change in internal energy \triangle V

\triangle V=nC_v \triangle T\\

\triangle V=0

Therefore with

\triangle T=0

\triangle v=0

The gas A and B have same internal energy

You push a 50 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.15. N
WARRIOR [948]

Answer:

0.68 seconds

Explanation:

Data provided in the question:

Mass of the box = 50 kg

Speed of the box = 1.0 m/s

Coefficient of friction, μ = 0.15

Now,

Force applied = μmg    

Here,

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

Thus,

F = 0.15 × 50 × 9.8

= 73.5 N

Also,

Force = Mass × Acceleration

thus,

73.5 N = 50 × a

or

a = 1.47 m/s²

After doubling the speed

Final speed = 2 × Initial speed

= 2 × 1 m/s

= 2 m/s

Also,

Acceleration = [change in speed] ÷ Time

or

1.47 = [ 2 - 1 ] ÷ Time

or

Time = 1 ÷ 1.47

or

Time = 0.68 seconds

Different betweenof mass and weight​
Eduardwww [97]

Answer:

The differences are:

Mass:

1) It is the total amount of matter contained in a body.

2) It's SI unit is kilogram (kg).

3) It's measured by using beam balance

Weight:

1) It is the force which pulls an object towards the center of the earth.

2) It's SI unit is newton(n).

3) It's measured by using spring balance.
