The kinetic energy of a ball with the mass of 0.5 kg and a velocity of 10 m/s is what
slamgirl [31]

Answer:

25J

Explanation:

Kinetic energy = 1/2 mv²

Mass = m= 0.5kg

Velocity = v = 10m/s

K. E = 1/2 x 0.5 x 10 x 10

K. E = 0.5 x 5 x 10

K. E = 2.5 x 10

K. E = 25 J

The S. I unit of energy is joules with symbol J

Two identical small charged spheres are a certain distance apart, and each initially experiences an electrostatic force of magni
Rom4ik [11]

Answer:

New force, F'=\dfrac{1}{4}F

Explanation:

The electrostatic force between two spheres is given by :

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

According to given condition, each of the spheres has lost half its initial charge, new force is given by :

F'=\dfrac{kq_1/2q_2/2}{r^2}

F'=\dfrac{1}{4}\times \dfrac{kq_1q_2}{r^2}

F'=\dfrac{1}{4}F

So, the new force becomes (1/4)th of the initial force. Hence, the correct option is (d).
