Answer:
<h2>900 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question is we have
force = 75 × 12
We have the final answer as
<h3>900 N</h3>
Hope this helps you
Answer:
The three types of impact that occur are those involving the vehicle, the body of the vehicle occupant, and the organs within the body of the occupant.
Answer:
(a)
(b)
Explanation:
Hello.
(a) In this case, since the initial volume is 18.5 dm³ and the final volume is 21 dm³ (18.5 +2.5), we can compute the work at constant pressure as shown below:
Which is negative as it expands against the given pressure.
(b) Moreover, of the process is carried out reversibly, the pressure can change, therefore, we need to compute the work via:
Whereas the moles are computed from the given mass of argon:
Thus, the work is:
Regards.
Mass doesn't affect velocity at all; gravity affects everything the same (9.8meters/seconds^2)
Answer:
Scientists can discuss and compare very large numbers, which is useful because substances in everyday quantities contain very large numbers of atoms and molecules.
