The kinetic energy of the proton is 3.4 kev
1 kev = 1.602 × 10^-16 joules
therefore 3.4 kev is equivalent to;
3.4 × (1.602 ×10^-16)= 5.4468 × 10^-16 J
Kinetic energy is calculated by the formula 1/2mv² where m is the mass and v is the velocity.
Therefore V = √((2 × ( 5.4468×10^-16))/ (1.67 ×10^-27))
= 8.077 × 10^5 m/s
<h3><u>Answer;</u></h3>
B. the rotation of Earth on its axis
<h3><u>Explanation;</u></h3>
- <em><u>The Coriolis effect describes how the Earth's rotation steers winds and surface ocean currents. The Coriolis effect causes the motion of a freely moving object to appear as a curve.</u></em>
- <em><u>Therefore, since air and water move freely, the Coriolis effect makes their movement to be curved. This is why the movement of winds and oceans does not follow a straight line but it is bent and curved.</u></em>
Answer:
at ( or below)
Explanation:
at the dewpoint.......water will condense out of the air onto the surface
The average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.
<h3>How to calculate the Average speed?</h3>
The average speed can be calculated by adding the speed of each trial divided by the number of trials,
For 0.25 m the average speed will be:
For the 0.50 m, the average speed will:
Therefore, the average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.

Answer:
No
Explanation:
I don't think the universe has a starting and ending point because the universe is vast and has not been fully discovered. I think that the universe is endless because all of the stars, planets, and galaxy's have yet to be found and the end or start of the universe is also yet to be discovered so I think that the universe could go on forever.
