It has only magnitude of body and not indicate the direction of body.Example. electric potential force.
Answer:
Explanation:
Given data
Distance S=6.10 m
Initial Speed u=12.0 m/s
To find
Final Speed v
Solution
From third equation of motion we know that:
where
v is final velocity
u is initial velocity
a is acceleration
S is distance
Substitute the given values to find v
A electron has a negative charge. They represent energy levels.
An example of the use of an electron is the spherical shell. The larger the shell, the more energy the electron has.
Answer:
Either heat added or mechanical work done.
Explanation:
Since he found stirring rod on the desk and a cigarette lighter. This means that the beaker was probably either heated with the aid of fire from the lighter.
Also, the stirring rod could have been used to stir the water which will increase the kinetic energy which also means an increase in temperature.
Thus, it's either heat was added or mechanical work was done as a result of stirring.
