Answer:
None of the above.
The correct answer would be momentum
Answer:
C) >A)>B)
Explanation:
We know that force per unit area is known as pressure.But we have to understand that this force should be perpendicular to the area.
P = F/A
P=Pressure
F= Force
A=Area
A)
Given that
ΔP=2.9 N/m²
A=1500 m²
F= ΔP x A
F= 2.9 x 1500
F=4350 N
B)
Given that
ΔP=4.7 N/m²
A=900 m²
F= ΔP x A
F= 4.7 x 900
F= 4230 N
C)
Given that
ΔP=8.8 N/m²
A=500 m²
F= ΔP x A
F= 8.8 x 500
F=4400 N
4400 N > 4350 N > 4230
C) >A)>B)
The land form is formed by lava flows of low viscosity
Hope this helps! :)
<h3>
Answer:</h3>
539.56 Joules
<h3>
Explanation:</h3>
- Efficiency of a machine is the ratio of work output to work input expressed as a percentage.
- Efficiency = (work output/work input) × 100%
- Efficiency of a machine is not 100% because so energy is lost due to friction of the moving parts and also as heat.
In this case;
Efficiency = 94%
Work input = 574 Joules
Therefore, Assuming work output is x
94% = (x/574 J) × 100%
0.94 = (x/574 J)
<h3>x = 539.56 J</h3>
Thus, you get work of 539.56 J from the machine
