Answer:
Explanation:
We know that,
Where m is mass and v is velocity or speed.
Putting the required values,
divide both side by 144
So the mass of the diver is 70 kg respectively.
B. d = wf
C. f = wd
D. f = dw
A.) sodium and sodium chloride
B.) sodium chloride and chlorine
C.) sodium and chlorine
The correct choice is
C.) sodium and chlorine
In a reaction, reactants are the compound or elements which gets combined or reacts to give another compound known as product. Here sodium is getting combined with chlorine gas to give the product as sodium chloride. hence Sodium and chlorine can be termed as reactants and sodium chloride can be termed as product.

mechanical waves?
(1) Both types of waves travel at the same speed.
(2) Both types of waves require a material medium
for propagation.
(3) Both types of waves propagate in a vacuum.
(4) Both types of waves transfer energy.
Answer: The correct answer is (4).
Explanation:
Electromagnetic wave is the transverse wave. It is produced by the moving charged particle. It travels at the speed of the light. It does not require a medium to travel. It can travel through the vacuum.
In mechanical wave, there is an oscillation of matter. It requires a medium to travel.It cannot travel through vacuum. The three types of mechanical waves are longitudinal wave, transverse wave and surface wave.
The common characteristics to all electromagnetic waves and mechanical waves are both can move through matter and both can occur as a result of a disturbance. This disturbance is a result of wave transfer energy.
Therefore, the common characteristic to all electromagnetic and mechanical waves is both types of waves transfer energy.

sac
hole
Answer: sac
Tunicates are sea squirts that are found in the marine water. These animals remain attached to the rocks and sea beds. They exhibit a body shape which looks like a barrel. The barrel has two openings called siphons. These siphon helps in the intake of the food particles and oxygen. These animals look like a sac on the sea floor.
Hope this helps :)
