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.
Answer:
1000kg
Explanation:
We can use the equation "p=mv"
- p is the momentum in kg m/s
- m is the mass measured in kg
- v is the velocity measured in m/s
If we rearrange the equation to find mass (m), then the equation becomes:
m=p/v
We can substitute in the values of p and v as they are already given in the question.
So, now we just substitute in the values to get our answer.
m=p/v
m=25,000/25
m=1000kg
It's because honey has a different viscosity than water.
Answer:
the factor that contributed to the fact that he was able to survive this fall is due to the fact that his body is made up of bone which are strong and his skeleton also protected all his vitals internal organs. His body went limp after he was knocked in the head when he fell, all of these made room allowing his muscles to relax and this gave his bones the opportunity to absorb the impact of the fall
