The hall voltage is the potential created across a current-carrying metal-strip when the strip is placed in a magnetic field per

pendicular to the current flow in the strip. it is used as a research tool to probe the movement of charges in materials, as well as determining the blood flow rate. one fundamental use of the hall effect is the determination of the charge of the charge carriers. what of the following statements is true concerning the strips with a positive versus a negative hall voltage?
a) the top strip has positive charge carriers, and the electric field points in the same direction as the electric force.
b) the bottom strip has positive charge carriers, and the electric field and electric force point in the same direction.
c) the top strip has negative charge carriers, which get deflected to the top of the plate.
d) the bottom strip has negative charge carriers, and the magnetic force points upward along the plate.

The statements true concerning the strips with a positive versus a negative hall voltage are a and d.

<h3>What is hall voltage?</h3>

The hall voltage is the potential created across a current-carrying metal-strip when the strip is placed in a magnetic field perpendicular to the current flow in the strip. it is used as a research tool to probe the movement of charges in materials, as well as determining the blood flow rate.

The top strip possess positive charge carriers, and the electric field points are in the same direction as the electric force.

The bottom strip has negative charge carriers, and the magnetic force points upward along the plate.

This will create an equilibrium of the magnetic force and electrostatic force.

Thus, the correct option are a and d.

How much energy must a refrigerator absorb from 225 g of water so that the temperature of the water will drop from 35°c to 5°c
patriot [66]

Heat energy required to change the temperature is given by

Q = ms\Delta T

here we know that

m = 225 g = 0.225 kg

s = 4186 J/kg C

T_i = 5 ^0C

T_f = 35 ^0C

now from above formula we will have

Q = (0.225 kg)(4186 J/kg C) (35 - 5)

Q = 28255.5 J

So it will remove 28255.5 J heat from the water

Which molecules dramatically increases the rate of diffusion of water across cell membranes?
Lorico [155]

Answer:

AQUAPORINS dramatically increases the rate of diffusion of water across cell membranes.

Explanation:

Aquaporins are integral membrane proteins also called water channels that forms pores in the membrane mainly for facilitating diffusion of water molecules in and out of the cell. Aquaporins selectively allow the passage of water molecules while preventing the passage of ions and other solutes through it as they are impermeable to protons, and large solutes. These proteins therefore increases the permeability of the membrane to water molecules and the rate of diffusion of water increases through them. Flow of water molecules in aquaporins follows the direction of osmotic pressure across the membrane. Aquaporins in some organisms have been modified to voltage gated aquaporins which helps them to close the water channels in unfavorable conditions such as drought and flooding. This is to prevent excessive loss of water to the surrounding or intake of water into the cells.

A student decides to spend spring break by driving 50 miles due east, then 50 miles 30 degrees south of east, then 50 miles 30 d
PolarNik [594]

Answer:

a. 600 ml, 12

Explanation:

The movement described in the question exhibits that of a polygon. Exhibiting a constant distance and angle with only varying direction until the starting point is reached.

The sum of exterior angles of a polygon = 360 degrees.

Exterior angle of a polygon = (360 ÷ number of sides)

Therefore,

Number of sides = 360 ÷ exterior angle

Exterior angle = 30 degrees

Hence,

Number of sides = 360 ÷ 30 = 12 sides

Since distance traveled of 50 miles is the same for each displacement ;

Total displacement = distance traveled * number of sides

Total displacement = 50 * 12 = 600 miles.

What two things must exist for an electric current to be produced?A pair of highly conductive materials and a conducting path be
Andrei [34K]

The two things that must exist for an electric current to be produced are:

An electric potential between two bodies and a conducting path joining the bodies.

This comes from the fact that when there is a potential difference there is an electrical field and hence a force that makes some free charges to move in the conductor. For this reason, there's an electrical current.

A 50-foot flagpole is at the entrance of a building that is 300 feet tall. If the length of the flagpole's shadow is 30 feet at
natka813 [3]
First you will want to sketch out both of the situations. It should be two sketches, one for the flagpole and one for the building.

To solve this, you will want to create a proportion.

Flagpole height/flagpole shadow=building height/building shadow

Therefore, it should look like this:
50/30= 300/x

Solve for x:
50x=9,000
X= 180 feet
