The object will sink in any liquid whose density is less than 0.75 g/mL .
A few examples are butane, ether, gasoline, hexane, octane, naphtha, pentane, and propane.
Answer:
Whether the force exerted by the locomotive on the wall was larger
Than the force the locomotive could exert on the wall.
Explanation:
The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.
So we have;
F12=-F21
F12 is the force in a direction
-F21 is the force in the opposite direction.
Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.
By definition;
M = fo/fe
Where,
M = Angular magnification
fo = Focal length of objective lens
fe = Focal length of eyepiece lens
From the information given;
M = 180/30 = 6
Because the Earth<span> is a sphere, the surface gets much more intense </span>sunlight<span>, hence heat, at </span>the equator<span>than at the poles.</span>
