Explanation:

You ask a good question and the answer could be as the following:

A simple machine uses one applied power to do action against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of production force, at the expense /cost of a relative decrease in the distance moved by the load.

Now,the question can be 'How can machines make the work easier?'

Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. ... That's because a machine doesn't change the amount of work and work equals force times distance.

<u>Some simple examples of machines:</u>

The inclined plane.

The lever.

The wedge.

The wheel and axle.

The pulley.

The screw.

Hope you're satisfied with my answer.. Good Luck!

The voyage of the H.M.S what important because

yaroslaw [1]

C. Physicalist chemist and biologist conducted experience in gather collection that changed existing scientific knowledge about the oceans

Explanation:

The voyage of Her Majesty's Ship was highly important because it furnished scientists with rich evidence about a lot of phenomenon under study and this changed existing scientific knowledge about the ocean.

H.M.S II was an expedition to study and map the ocean floor using some sophisticated and newer devices.
It was through this expedition that the theory of plate tectonics was modified and became a theory
The bathymetry of the ocean floor was also carried out.
The mid-oceanic ridge was discovered through the expedition.
Some rare species of organisms were also obtained from the ocean floor in this process.
The H.M.S second expedition after the world war was very crucial and helped furthered scientific knowledge about the oceans.

The gravitational attraction between a 20 kg cannonball and a 0.002 kg

Naya [18.7K]

Answer:

$2.966\times 10^{-11}\ N$

Explanation:

Given:

Mass of the cannonball (M) = 20 kg

Mass of the marble (m) = 0.002 kg

Distance between the cannonball and marble (d) = 0.30 m

Universal gravitational constant (G) = $6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2}$

Now, we know that, the gravitational force (F) acting between two bodies of masses (m) and (M) separated by a distance (d) is given as:

$F=\dfrac{GMm}{d^2}$

Plug in the given values and solve for 'F'. This gives,

$F=\frac{(6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2})\times (20\ kg)\times (0.002\ kg)}{(0.30\ m)^2}\\\\F=\frac{6.674\times 20\times 0.002\times 10^{-11}\ m^3 kg^{-1+2} s^{-2}}{0.09\ m^2}\\\\F=2.966\times 10^{-11}\ kg\cdot m\cdot s^{-2}\\\\F=2.966\times 10^{-11}\ N.........(1\ N = 1\ kg\cdot m\cdot s^{-2})$

The same force is experienced by both cannonball and marble.

Therefore, the gravitational force of the marble is $2.966\times 10^{-11}\ N$
