Alever has a mechanical advantage of 5. how large would a force need to be to lift a rock with a mass of 100kg

196 Newton force is needed to lift a rock.

Explanation:

We know a formula, Mechanical advantage × effort applied = Load lifted. In this question, mechanical advantage of lever = 5 Load lifted = Mass of the rock × acceleration due to gravity = 100 × 9.8 = 980N so, putting the given values in the formula, Therefore a force of 196 Newton is required to lift a rock of 100 kg with mechanical advantage 5.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
