Two charges, -20 C and +4.7 C, are fixed in place and separated by 3.0 m. a. At what spot along a line through the charges is th

e net electric field zero? Give the distance of the spot to the positive charge in meters (m). (Hint: The spot does not necessarily lie between the two charges.) b. What would be the force on a charge of +14 C placed at this spot?

The zero net electric field point is at a point that is 0.98 m away from 4.7C charge.If a 14C charge is placed at this point then, force acted on the charge placed at this point is equal to zero.

Explanation:

Let at A both net electric field is zero then

At A ,E1=E2

E1=k*Iq1I / (d+x)^2

E2=k*Iq2I /x^2

Equating both

A cook had a jar containing a sweet food and a jar containing a sour food. The sweet food has a strong attraction between its mo
patriot [66]

Answer:

The sweet food changed because the molecules were able to move fast enough to overcome the attraction between them with its molecules now moving away from each other.

Explanation:

We are told that the sweet food has a strong attraction between its molecules, and the sour food has a weak attraction between its molecules.

This means that the molecules in the sweet food would be moving at a faster rate than in the sour food because of the strong forces of attraction. Therefore, the molecules in the sweet food would be moving far away from each other hence the change of phase.

What is the effective dose to a worker who receives uniform, whole-body dose of 8.4 mGy from gamma-rays and 1.2 mGy from 80-Kev
Vera_Pavlovna [14]

Given :

Whole-body dose of 8.4 mGy from gamma-rays and 1.2 mGy from 80-Kev neutrons.

To Find :

The effective dose to a worker.

Solution :

By the given information effective dose to a worker is given by :

E.D = ( 8.4 × 1.2 × 0.12 ) + ( 1.2 × 1 × 1 )

E.D = 1.2096  + 1.2

E.D = 2.4096

Therefore, the effective dose to a worker is 2.4096 .

2. Another car weighs 2000kg, you can push it .05 m/s?, how much force are you
Vesna [10]

Answer:

\boxed {\boxed {\sf 100 \ Newtons}}

Explanation:

We are asked to calculate the force you are applying to a car. According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, we can use the following formula to calculate force.

F= m \times a

The mass of the car is 2000 kilograms and the acceleration is 0.5 meters per second squared.

  • m= 2000 kg
  • a= 0.05 m/s²

Substitute the values into the formula.

F= 2000 \ kg \times 0.05 \ m/s^2

Multiply.

F= 100 \ kg *m/s^2

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 100 kilogram meters per second square is equal to 100 Newtons.

F= 100 \ N

You apply <u>100 Newtons</u> of force to the car.
