Yes this true because Someone moves forward for 5 seconds and moves back for 5 seconds
Which 5+5=10
so you would have in ten seconds
-- Momentum is (mass) x (speed).
Object B has 1.5 times as much momentum as Object A has.
-- Kinetic energy is (1/2) x (mass) x (speed) .
Object B has 1.5 times as much kinetic energy as Object A has.
-- If they would both stop long enough to get on the scale,
Object B would weigh 1.5 times as much as Object A does.
<h2>The atomic mass of silicon is 28.0855</h2>
Answer:
the presence or absence of functional groups
Explanation:
The functional group is the group of atoms that characterize a chemical function and that have well-defined characteristic properties.
In organic chemistry, the functional group is a set of submolecular structures, characterized by a specific elementary connectivity and composition that confers specific chemical reactivity to the molecule that contains them. These structures replace the hydrogen atoms lost by saturated hydrocarbon chains. Aliphatic, or open chain, groups are usually represented generically by R (alkyl radicals), while aromatic ones, or derivatives of benzene, are represented by Ar (aryl radicals).
Explanation:
As we know that the maximum of thermal energy will be converted into mechanical energy.( The thermal energy will be given to us by engine.)
But the total thermal energy will not be converted into the mechanical energy, there will be some lost of energy. The lost of mechanical energy will be in multiple forms. 2 of them are
1.Heat : The mechanical energy heats up the engine and then it will lost some energy.
2.Noise : Some energy also lost in the sound or the noise comes out from the engine. It will consume some energy.
Also, the engine never be 100% efficient some amount of energy lost in environment also.
