Calculate the mechanical advantage of a lever that is able to lift 300 N rock with an effort force of 50 N. Please help

6 with speed advantage
0.16666 with speed advantage
6 with force advantage
0.16666 with no advantage

6 with force advantage

Explanation:

The following data were obtained from the question:

Load = 300N

Effort = 50N

Mechanical advantage =.?

Mechanical advantage is defined by the ratio of load that of the force (effort) applied. It is represented mathematically as:

Mechanical advantage = load/effort

Using the above equation, we can obtain the mechanical advantage of the lever as follow:

Mechanical advantage = load/effort

Mechanical advantage = 300/50

Mechanical advantage = 6

Since a force force was applied to raised the load, therefore, the mechanical advantage is 6 with force advantage.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
