Answer:
Option "D" is the correct answer to the following question.
Explanation:
According to The law of conservation of mass, in a chemical reaction mass neither created nor destroyed.
So,
Total product = Mass of magnesium + Mass of oxygen
Total product = 40 gram + 40 gram
Total product = 80 gram
Therefore, option "D" is the correct answer
with the same generator, so the only factor for producing
the slectric field is only the speed. The faster the rotational speed of the
generator the greater it produce electric field. So the sequence is 3000 rpm
< 3200 rpm < 3400 rpm < 3600 rpm
handle with a force of 87 N, how much work is done?
The work done on the wagon is 3549 J
Explanation:
The work done by a force when moving an object is given by
where:
F is the magnitude of the force
d is the displacement
is the angle between the direction of the force and of the displacement
In this problem we have the following data:
F = 87 N is the magnitude of the force
d = 44 m is the displacement of the wagon
is the angle between the direction of the force and the displacement
Substituting, we find the work done
