Answer:
no work is said to be done by standing man carrying 500kg load because
Explanation:
for the work to be done there should be two conditions i.e force should be applied and displacement must be covered.So for a man carring a 500 kg load force is there but he covers no distance by standing so displacement will be zero and since
work =force\displacement
displacement is zero so we can say that no work is done
Use choice B. 1 km / 1000 m
from what result that 18 km = 18 000 m
hope helped
<span>According to Gas Law, PV =nRT
where, P : Pressure
V : Volume
n : number of moles
R : Gas Constant
T : Temperature
since, P is indirectly proportional to V
therefore, P1/V1 = P2/V2
P2 = 3*P1
P1/12 = 3*P1/V2
V2 = 36 L
Answer : 36 L</span>
20,028 feet is 3.793 miles
The summit of Mt. Everest is 29,029 ft above sea level. That's 5.498 miles.
The examples may be;
making yogurt; If you heat beyond 130F you kill the cultures. The higher the temperature up until that point the faster it cultures until you close in on killer temperature.
Mixing 2 part epoxy; Keep it cool and the reaction time is delayed. On the other hand, heat it up and epoxy reacts quicker. In the winter time and close to 35 Degrees, the reaction time for cement to harden can take 400% more time to set.
