<h3><u>Answer;</u></h3>

Nuclear fusion

<em><u>Nuclear fusion</u></em> reactions convert protons into helium; thus, becoming the source of all energy radiated by the sun.

<h3><u>Explanation;</u></h3>
  • <em><u>Nuclear fusion is a type of nuclear reaction</u></em> in which two or more nuclei of atoms join to form one or more different atomic nuclei and subatomic particles.
  • <em><u>Nuclear fusion takes place in the sun where protons or hydrogen nuclei collide in a nuclear fusion reaction at very high temperatures to form Helium.</u></em> This nuclear fusion results in the conversion of 4 hydrogen atoms into helium atom.

Kelly is riding a bicycle, moves with an initial velocity of 5 m/s. Ten seconds later, she is moving at 15 m/s. What is her acce
sladkih [1.3K]

Answer:

her acceleration is 1 m/sec

Explanation:

The following information is given in the question

The initial velocity is 5 m/s

After 10 seconds, she would be moved at 15 m/s

We need to find the acceleration

As we know that

Acceleration = Change in speed ÷ time

Acceleration = (15 - 5) ÷ (10)

= 1 m/sec

Hence, her acceleration is 1 m/sec

The same would be considered

An ice skater accelerates backward for 5.0 second to final speed of 12m/s. If the acceleration backward was at a a rate of 1.5m/
Lisa [10]

Answer:

Initial velocity, U = 4.5m/s

Explanation:

Given the following data;

Final velocity, v = 12m/s

Time, t = 5 seconds

Acceleration, a = 1.5m/s²

To find the initial velocity, we would use the first equation of motion.

V = U + at

Where;

V is the final velocity.

U is the initial velocity.

a is the acceleration.

t is the time measured in seconds.

Substituting into the equation, we have;

12 = U + 1.5*5

12 = U + 7.5

U = 12 - 7.5

Initial velocity, U = 4.5m/s
