The body for which its
(Mass) / (radius squared)
is the greatest.
Answer:

Explanation:
Let
be % of
at time
(time in minutes).
Amount of
in room=Volume of room 
Rate of change of
in room=Volume of room x 

Rate of inflow of
=

Rate of
outflow

Therefore rate of change of
is 
% rate of change is
Therefore we have:

Integrate both:


In
In

Raise both sides to base

Initially, there's only 0.25% of
,
Now substitute
and 


Answer:
Sublimation occurs more readily when certain weather conditions are present, such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes, where the air pressure is less than at lower altitudes. Energy, such as strong sunlight, is also needed.
In solid, atoms are compact. Hence they have definite shape and volume. Hence it is true.
Explanation:
force = mass × acceleration
Solving for acceleration:
acceleration = force / mass
To find the acceleration, divide each force by the mass. For example:
a = 480 N / 62 kg
a = 7.74 m/s²
