2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
Answer:
Time=7.84hrs
Explanation:
This is an inverse proportionality questions
Mathematically time t varies as 1/distance d
Hence T= dk/r
But speed r = distance/t
d= r*t= 9*20=180km/hr
We're k= constant of proportionality
At t=9hrs d=180km/hr
Hence k=r*t/d=20*9/1620=0.111
Finding t at at 1620km for 23km/hr
t=1620*0.111/23=7.84hrs
Total flour was 5 pounds
Ramsey divided it in 3 bowls equally
it means now
3 bowls has = 5 pounds of flour
to get in 1 bowl we we can divide by 3 both sides
3/3 bowl has = 5/3 pounds of flour
1 bowl has = 5/3 pounds
Depends on what type of gass
