Answer:
1470Joules
Explanation:
Workdone = Force * distance
Since the worker pushes the crate up the 3m ramp. The distance covered is 3m
Force = Mass * Acceleration due to gravity
Force = 50*9.8
Force = 490N
Workdone = 490 * 3
Workdone = 1470Joules
Hence I did 1470Joules of work
Answer:
Neutrons are the particles which are present in the nucleus of an atom. These have a neutral charge, means that the don't have a positive charge like proton or a negative charge like an electron, but these are far more dense than electrons and protons. Under normal reaction, neutron may seem to just exist, as usually electrons are the particles which forms bonds or breaks them.
However, Neutrons play an important role in the weight and Radioactive properties of a material. During radioactive decay, which occurs in radioactive elements, the nucleus of an atom breaks down and releases energy and matter, which is primarily due to the knocking out of a neutron. These knocked out neutrons forms the basis of the nuclear fission and fusion reactions.
Answer:
51.04 joules
Explanation:
The movement by the gloves = 11cm
Force by the baseball = 464N
First of all we are going to convert cm to metres
11cm = 11/100 meters = 0.11m
The formula for workdone is given as:
W = f x d
W = workdone
F = force
D = distance
Workdone = 464 x 0.11
= 51.04 joules
The workdone by the ball is 51.04 joules
