Answer:
C. Chemical energy
Explanation:
The different types of energy listed in this question are:
A) Electrical energy: it is the energy related to the flow of electrical charges (current)
B) Nuclear energy: it is the energy contained in the nuclei of the atoms, and released during nuclear reactions
C) Chemical energy: it is the energy contained in the bonds between molecules, and it is released during chemical reactions
D) Thermal energy: it is the energy associated with the motion of molecules
Photosynthesis is the process that plants use to transform the light energy (coming from the Sun) into chemical energy. In fact, in this process, plants absorb CO2 (from the atmosphere) and solar energy (from the light), and they convert them into sugars (glucose) and oxygen. Therefore, the initial energy coming as solar energy is converted into energy of the bonds of the molecules of glucose (so, chemical energy).
So, the correct option is C).
Answer:

Explanation:
Using Kepler's third law, we can relate the orbital periods of the planets and their average distances from the Sun, as follows:

Where
and
are the orbital periods of Mercury and Earth respectively. We have
and
. Replacing this and solving for

Answer:9m
Explanation:
Ball starts from rest . Time taken = 6 seconds. Distance travelled by ball. ∴Distance travelled = 9 m

Answer:
(a). The density of the object is 1382 kg/m³.
(b). The density of the oil is 536.4 kg/m³.
Explanation:
Given that,
Weight in air = 79.1 N
Weight in water = 21.8 N
Weight in oil = 48.4 N
We need to calculate the volume of object
Using formula of buoyant force




Put the value into the formula



We need to calculate the density
Using formula of buoyant force




The density of the object is 1382 kg/m³.
(b). We need to calculate the volume of object
Using formula of buoyant force



We need to calculate the density
Using formula of buoyant force




The density of the oil is 536.4 kg/m³.
Hence, This is the required solution.
Answer:
for one they will stay there. And another thing it will do is collect rust pretty much destroying it.
