Answer:
Mechanical advantage = 3
Explanation:
You exert a 100-N force on a pulley system to lift 300-N.
The mechanical advantage of the system is given by the ratio of output force to the input force.
Here, output force = 300 N and input force = 100 N
Mechanical advantage,
Mechanical advantage is 3 it means that there are 3 sections of rope support. Hence, this is the required solution.
Answer: yeah it is reflection
Answer:
d = 506.25 ft
Explanation:
As we know by kinematics that
here we know that initially the stone is dropped from rest from the edge of the roof
so here initial speed will be zero
now we have
also the acceleration of the stone is due to gravity which is given as
now we have
so from above equation
Answer:
Nuclear Fusion
Explanation:
The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
Your answer is electricity, light and magnetism. They can be determined usinf elecromagnetic radioation.

Even the energy can't be detected by our eyes, there are a lot of measurement instruments that can measure infrared (IR), gamma rays, radio or X-rays or ultraviolet (UV)</span>
