Answer:
40J
Explanation:
work is force x distance = 4 x 10 = 40 J
Answer:
Lever
Explanation:
Fulcrum point is the point where the lever turns.
It is the center of a key activity
Hydraulic jacks, automobile brakes and even the lift generated on airplane wings can be explained using Pascal's principle. Pascal's principle is based on the idea that fluids at rest are incompressible, allowing very large forces to be transmitted with the application of a smaller force.
The Mass of the barter and the ball is 3.1kg
Data Given;
- F = 1.1*10^-9N
- r = 0.76m
- G = 6.67*10^-11 m^3 kg^-1 s^-1
Assuming the barter and the ball have equal mass, we can apply gravitational force formula.
<h3>Gravitational Force</h3>
This is product of the mass of the two bodies and divided by the square of their distance apart.
Substituting the values into the formula
From the calculations above, the mass of the barter and the ball is 3.1kg

Answer:
reservoirs and flows of the carbon cycle and how human activities
explication :
Today, the carbon cycle is changing. Humans are moving more carbon into the atmosphere from other parts of the Earth system. More carbon is moving to the atmosphere when fossil fuels, like coal and oil, are burned. More carbon is moving to the atmosphere as humans get rid of forests by burning the trees.
