PLEASE HELP ASAPPA man pushes a box with a force of 75.0 N across a 12.0 m loading dock. How much work did he do on the box? (Use formula W = F x d)

Work done, W = 900 joules

Explanation:

It is given that,

Force acting on the man, F = 75 N

Distance, d = 12 m

We need to find the work done by the man on the box. Let it is given by W. The work done of an object is equal to the product of force and distance. Mathematically, it can be calculated as :

W = F × d

W=75\ N\times 12\ mW=75 N×12 m

W = 900 joules

So, the work done by the man on the box is 900 joules. Hence, this is the required solution.

hope it is helpful

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
