Answer:

The electric field at the location of the point charge is defined as the force F divided by the charge q: Figure 23.1. Electric force between two electric charges. The definition of the electric field shows that the electric field is a vector field: the electric field at each point has a magnitude and a direction.

Answer:

In a primary cell, two electrodes (one of copper and other of zinc) of metal atoms are used. These electrodes are dipped in an electrolyte solution that causes the metals to produce their respective positive and negative ions.

In this way, the flow of charges takes place and supply the electricity to the source.

Unlike a primary cell, a dry cell contains paste of an electrolyte instead of the solution. The contents of electrolyte paste react with each other through a chemical process and convert the chemical energy into electrical energy.

Who exerts more pressure? a) A girl of 50 kg, wearing heels with an area of 1 cm2. b) An elephant of 4000 kg with foot area of 2

Mrrafil [7]

Answer:

The girl exerts more pressure.

Explanation:

Pressure can be defined as the force exerted normally or perpendicularly per unit area.

i.e P = F/A

Girls

Area of the heel = 1cm² = 10^(-4) m²

Force = mg = 50 × 10 = 500N

Pressure =

$\frac{500}{10 ^{ - 4} }$

$= 5 \times {10}^{6}$

Elephant

Area = 250cm² = 2.5 x 10^(-2)b m²

Force = mg = 40000N

Pressure =

$\frac{40000}{2.5 \times {10}^{ - 2} }$

$= 1.6 \times {10}^{6}$

5280 feet to meters

lesya [120]

Answer:

1m= 3.2 feets

? = 5280 feets

let ? be n

cross multiply

3.2n = 1×5280

n= 5280÷3.2

n= 1650

so, 5280 feets is equal to 1650 metres

ANSWER FAST PLZZ!!

Dahasolnce [82]

Answer:

See the answer below

Explanation:

The two correct options are:

1. The student traveled the fastest between 4 and 5 minutes

2. The average speed of the student is 4 meters per minute

Between 4 and 5 minutes, the approximate distance of 7 meters covered by the student is the longest of all the distances covered per minute. Since speed is a measure of distance covered relative to time, it means that the student traveled the fastest between these periods.

The average speed is calculated by dividing the total distance traveled by a body by the total time taken to cover the distance.

From the graph:

Total distance covered = 20

Total time taken = 5

Average speed = 20/5 = 4 meters per minute

All the remaining conclusions are incorrect or indeterminate going by the information on the graph.

How are NGC 1427A and U different? How are they the same?

Lelechka [254]

Answer: NGC 1427A has no general shape, so it is an irregular galaxy. U has a bulge in the center and arms, so it is a spiral galaxy. They are similar in that both contain plenty of dust and gas. Both also have active star-forming sites.
