Question

pls give me answers with solution all the 1,2,3,4,5,questions pls

Answer 1

1)no. of horses=2
force applied by each=1000N
therefore,resulatant force=2×1000N
=2000N

2)total force applied by team A=300N(80+100+120)
total force applied by team B=315N(85+125+105)
therefore, resultant force=315-300=15N.
also as team B applied more force than team A it is the winner.

3)weight=thrust=250N
surface area=10m^2
as we know that, pressure=thrust/area
=250/10=25pa

4)weight=thrust=16N
length (l)=32cm=0.32m
breadth (b)=10cm=0.1m
area=l×b
=0.32m×0.1m
=0.032m^2
as we know that, pressure=thrust/area
=16/0.032
=500pa

5)force=weight=thrust=120N
surface area=3m^2
as we know that pressure=thrust/area
=120/3=40pa



hope this helps! please mark me as brainliest:")
