Answer:

<em>The correct option is C) spreads out over a large area on the object. </em>

Explanation:

In physics, a ground can be described as a reservoir object in which charge can be stored. Grounding refers to the removal of charge in an object by using the ground object. When an object with excess if charge is placed on the ground object, the electrons are transferred from the charges object to the ground object. This charge begins to spread evenly in the ground object with the passage of time.

14. What is the mass of a 250 N bag of groceries?

Veseljchak [2.6K]

Answer:

mass = 25.5kg

Explanation:

The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the value of gravitational acceleration on Earth, g, of about 9.8 m/s².

Mass, m = $\frac{Force}{acceleration due to gravity}$

$mass,m=\frac{F}{g} = \frac{250}{9.8}= 25.5 kg$

Answer:

(i) C=3Co

(ii) V=Vo/3

(iii) Decrease

Explanation:

(i) capacitance increase K times.

(ii) As charge remain constant so by using Q=CV

you will get potential decrease by K time.

(iii) Decrease due to induced electric field inside

Select the correct answer.

Triss [41]

Answer:

Jim's kinetic energy is 54.67 J.

Explanation:

Given that,

Mass, m = 15 kg

Velocity, V = 2.7 m/s

We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :

$E=\dfrac{1}{2}mv^2$

$E=\dfrac{1}{2}\times 15\ kg\times (2.7\ m/s)^2$

E = 54.67 J

So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
