Answer:

option B

85 J

Explanation:

Given in the question,

mass of the dog = 7.2 kg

height it want to achieve = 1.2m

Formula to use

gravitational energy at maximum height = kinetic energy on the ground level

gravitational energy = mgh

<em> g = acceleration due to gravity = 9.8 m/s² </em>

<em> h = height</em>

plug values in the formula

7.2(9.8)(1.2)

84.672 J

≈ 85 J

What will happen to the force felt between two charged objects if the distance between them is 1/3rd of the original distance

kenny6666 [7]

Answer:

New force = 9(initial force)

Explanation:

The force between two charges is given by :

$F=\dfrac{kq_1q_2}{r^2}$

Where

d is the original distance

Let d' is the new distance such that, r' = r/3

New force,

$F'=\dfrac{kq_1q_2}{r'^2}\\\\F'=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\F'=9\times \dfrac{kq_1q_2}{r^2}\\\\F'=9F$

So, the new force becomes 9 times the initial force.

In which condition the final velocity becomes zero?

alexgriva [62]

Answer:

Terminal velocity is achieved, therefore, when the speed of a moving object is no longer increasing or decreasing; the object's acceleration (or deceleration) is zero.
