Answer:The pressure must be the same throughout the lift, so
P = F1/A1 = F2/A2 ⇒
A2 = (F2/F1)A1
F2 = 1,100 N
F1 = 15,000 N
A1 = 10 m2
Plug in the numbers and evaluate A2. The answer will come out in m2.

Answer:
Explanation:
The simplest kinetic model is based on the assumptions that:
(1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size;
(2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the walls of the container, but otherwise do not interact; and
(3) the transfer of kinetic energy between molecules is heat. These simplifying assumptions bring the characteristics of gases within the range of mathematical treatment.
Answer:
Work hasn't been done by Michael because no distance was covered.
Explanation:
Workdone is given by the formula;
Where;
W is the work done
F represents the force acting on a body.
s represents the distance covered by the body.
Hence, work hasn't been done by Michael because no distance was covered, as the table didn't move at all. Therefore, work done is zero.
The force acting on the object is constant, so the acceleration of the object is also constant. By definition of average acceleration, this acceleration was
<em>a</em> = ∆<em>v</em> / ∆<em>t</em> = (6 m/s - 0) / (1.7 s) ≈ 3.52941 m/s²
By Newton's second law, the magnitude of the force <em>F</em> is proportional to the acceleration <em>a</em> according to
<em>F</em> = <em>m a</em>
where <em>m</em> is the object's mass. Solving for <em>m</em> gives
<em>m</em> = <em>F</em> / <em>a</em> = (10 N) / (3.52941 m/s²) ≈ 2.8 kg
