Answer:
Yes
Explanation:
Yes, the orbital direction of a planet affect its Synodic period as seen from earth. The synodic period of mercury is about 116 days on Earth. Whereas the sidereal period of mercury as seen from Earth is 88 days. This difference is caused by the simultaneous motion of Earth in its orbit. Hence we can say that the orbital direction of a planet affect its synodic period as seen from earth.
Answer:
A., B. & C.
Explanation:
All apply, because all these happen in a plant.
Matter means the things that occupies space and has a mass.
So from this rule, we can identify the things given.
Toothpaste is a matter.
Happiness is not matter, it doesn't occupies space.
Gasoline is matter.
Sound doesn't have a mass, so it's not matter.
Bacteria is matter, it's one of the organisms in the 5 main kingdoms. It has a mass and it dies occupies space even its so small.
Cell is matter, because every living thing is made up of cells.
Answer:
Increase in total energy will be equal to the increase in the internal energy i.e 
Joules
Explanation:
Given
Weight of sledge hammer 
kilogram
Speed of sledge hammer 
meter per second
Kinetic energy is equal to half the product of mass and velocity square
Substituting the value of mass and velocity, we get -
It is given that one fourth of the energy is converted into internal energy
One fourth of kinetic energy is equal to
Increase in total energy will be equal to the increase in the internal energy i.e Joules
Heat required to decrease the temperature of body is given as
here given that
now by above equation
now in order to evaporate water the heat is given as
so 97 g of water will evaporate from the body
