When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

It acquires a positive electric charge.
Answer:
Explanation:
Work is equal to the product of force and distance.
The box is being pushed with an effort (force) of 45 Newtons and the distance is 3.5 meters.
Substitute the values into the formula.
Multiply.
- 1 Newton meter is equal to 1 Joule
- Our answer of 157.5 N*m equals 157.5 J
<u>157.5 Joules </u> of work are done on the crate.
Cause of high probability of accidents of loaded vehicles in over speed effected by momentum on the basis of first law of motion.
<h3>What does Newton's first law say?</h3>
When we are standing inside a bus and it brakes abruptly, due to inertia, we are thrown forward. When a car is going around a curve it is necessary for a force to act, otherwise the car will go in a straight line.
the cause of high probability of accidents of loaded vehicles in over speed occurs large amount of momentum.
