Aperson pushes against the raft as he dives into the water. as he moves forward the raft moves backwards in the water. the action force is his feet against the raft. what is the reaction force? water against the raft. raft against the water. raft against his feet.

The correct choice is

Raft against his feet.

according to newton's third law , every action has equal and opposite reaction. the action and reaction forces acts on two different objects in interaction with each other.

in the question given, the interacting objects are person's feet and raft. the feet apply action force on the raft, hence the reaction force must act on feet as applied by the raft . and the direction of two forces must be opposite.

Raft against his feet.

Explanation:

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
