500J
Explanation:
Given parameters:
Weight of the body = 50N
Height = 10m
Unknown:
Work done = ?
Solution;
Work done is the force that moves a body through a particular distance in the direction of the force.
In this problem, we can solve the problem by relating work done to the potential energy used in lifting the mass.
The weight on a body, a force in the presence of gravity
weight(weight) = mg
where m = mass of body
g = acceleration due to gravity
Work done = Fxd
Where F = force on the body
d = distance moved
Potential energy = mgh
where h is the height
P.E = work done = Weight x height = 50 x 10 = 500J

Answer:
utilization / effects
Explanation:
Utilization equipment are those equipment that makes use of electric energy for the purpose of chemical, electronic, lighting, heating, electro-mechanical or other alike purposes. Hence utilization best suits the first question mark in the question. Secondly, there are associated effects when current flows through a conductor, not responses.
It will be potential because the roller coaster is going down so it’s not giving off energy to the roller coaster.
The correct choice is
B. Double-replacement reactions
in this type of reaction , two ionic compounds react and swaps their cations or anions giving two new compounds in the product. hence the double replacement reactions does not deal with the nucleus. all other terms like strong nuclear forces, radioactivity and nuclear decay deal with the nucleus.
