A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?

A. The kinetic energy increases as its speed increases.

B. The kinetic energy decreases as it is converted into speed.

C. The kinetic energy remains the same because speed and kinetic energy are not
related.

D. There is no way to know what happens to the kinetic energy.

A. The kinetic energy increases as its speed increases.

Explanation:

The kinetic energy of an object is energy possessed by an object by virtue of its motion.

Now, kinetic energy of a moving body is given by;

KE = 1/2 mv^2

Where;

m = mass of the body

v = velocity (speed) of the body

It follows that if the mass of the spaceship is constant, a sudden increase in speed leads to a corresponding increase in the kinetic energy of the spaceship in accordance with the relationship show above.

explanation:

the marks go by 4s

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
