The efficiency of any machine is given by:
efficiency = output obtained / input given
Substituting the values,
Efficiency = 105 / 150
Efficiency = 0.7
Converting this to a percentage, the efficiency of the hammer is 70%.
This is a fairly high efficiency, and this is due to the fact that the hammer is a simpler machine. The more complex a machine is, the greater are the losses in it due to friction, meaning there is a lower efficiency.
Answer:
D.Geologists use data from three or more data stations to determine the location of the epicenter.
I think co 2 maybe
I cant remember
Answer:
Explanation:
Gravity:
It is the force by which the elements of matter pulls together.
Explanation:
The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.
The earth is most heavier than all other matter that's why all matter pulls towards the earth.
For example;
when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.
The gravitational force is inversely proportional to the square distance of interacting objects.
As the two objects are more distance apart from each other the less will be the gravitational force.
Answer:
26 Hydrogen atoms
Explanation:
H2O
Each hydrogen atom: 2+16 = 18g
Hence,
1 atom -> 18g
x atoms -> 709g
709/18 = 39 atoms
Therefore, 39 atoms give 709g
Hence, 26 Hydrogen atoms are used
