Answer:
45m
Explanation
Using third equation of motion which's vf^2 - vi^2 = 2gh in case of vertical motion so ,
step 1 : (30)^2 - (0)^2 = 2(10) h
step 2 : 900 = (20)h
step 3 : 900/20 = h
Answer:
Explanation:
Work can be found by multiplying the force by the distance.
The force is 100 Newtons and the distance is 5 meters. Therefore,
We can substitute the values into the formula.
Multiply.
- 1 Newton meter is equal to 1 Joule.
- Thus, our answer of 500 Newton meters is equal to 500 Joules.
You did <u>500 Joules </u>of work to push a shopping cart 5 meters with a force of 100 Newtons.
Newton's motion laws state that if an object is at rest or in movement, it will tend to maintain its basal state.
<h3>What are Newton's motion laws?</h3>
Newton's motion laws are a set of scientific statements aimed at explaining the physical property of movement.
These laws explain why objects in movement tend to maintain the same velocity for a short period of time.
In conclusion, Newton's motion laws state that if an object is at rest or in movement, it will tend to maintain its basal state.

Answer:
(3) mass-energy must be conserved
Explanation:
As we know that gamma rays are mass less and charge less photons which will have sufficient energy.
Now in case of Pair production the gamma photons convert its whole energy into mass by the law of Einstein's mass energy equivalence relation.
As per his relation we can say
here we will have
[tex]\Delta m[\tex] = mass produced
now we also have to think that here the two particles must have a pair of particles and antiparticles so that the combined mass system will have energy equivalent to the energy of gamma photons and also it must follow the conservation of charge
So here it will form an electron and a positron such that total charge will be zero and the energy will be same as energy of gamma photon.
while discovered less than 100 years ago isotopes are now used in a wide variety of scientific applications that touch the lives of almost every citizen.
