Explanation:
20 joule is your answer
Answer:
here
mass m =100kg
distance d=50m
acceleration due to gravity a =10m/s²
work =force×displacement
= ma/d=100×10/50=20joule
We have: Work done = Force × Displacement
Here, Force = 300 N
Displacement = 120 m
Substitute their values into the formula:
W = 300 × 120
W = 36000
In scientific notation, it would be: 3.6 × 10⁴
Finally, option C would be your correct answer.
Hope this helps!
Answer:
Change in force = 1.66 × 10⁵ N
Explanation:
Given:
Initial pressure = 837 mmHg
Final pressure = 842 mmHg
Rectangle (10 m ⨯ 25 m)
Find:
Change in force
Computation:
Change in force = (Change in pressure)(Area)(133 pa / 1 mmHg)
Change in force = (842 - 837)(10 m ⨯ 25 m)(133 pa / 1 mmHg)
Change in force = (166,250)
Change in force = 1.66 × 10⁵ N

Answer:
0.012 seconds
Explanation:
The time at which the soccer player maintain contact with the ball is as follows:
Given that
Change in momentum = 11 kg.m.s^-1
The Net force applied = F = 910 N
Now the following formulas should be applied:
For acceleration:
For momentum
Now
Put the values to the above formula
= 11 ÷ 910
= 0.012 seconds
