Question

Please finish these 4 questions will really help me I will give brainlist thank you’s Etc!! Pls and ty :)

Answer 1

Answer:

2. Force applied by the stored water=It's weight

Weight=mass*gravity

Mass=100kg

W=100*9.8 N

=980N

Pressure =980/area

=980/0.5

=490 pa

3. Pressure applied by Tom=70/30=2.33 N/cm2

Pressure applied by Sean=50/20=2.5N/cm2

So,pressure by Sean is greater.

4. Force in this case=Weight of the box

Pressure=Force/area

P=Weight /area

W=P*area

24kpa=24000Pa

80cm2=0.008m2

W=24000*0.008=192N
