Tommy and John are trying to move a large table. John pushes with a force of 1150N and Tommyhelps him by pushing on the same side of the table with a force of 800N. Sketch the individual forces exerted on thetable and then calculate and show the net force exerted on the table.
Answer:
Net force = 1150 + 800 = 1950 N
Explanation:
The diagram above illustrate the force applied to the large table by Tommy and John. The force are exerted in the same direction . The first arrow represent the force applied by John which was 1150 Newton and the second arrow represent the force exerted by Tommy which was 800 newton. There was no opposing force indicated like gravity from the question so no need to sketch that.
The forces were applied in the same direction, therefore, the Net force can be computed by adding their individual forces .
Net force = 1150 + 800 = 1950 N

Answer:
proteins.
and the essential functions will not be occurred
Answer:
The tea with milk and lemon curdles due to the acidic nature of lemon.
Explanation:
Milk is made up of a number of proteins like casein. The proteins in milk are denatured by the addition of lemon juice. When lemon juice is added to tea or milk, the proteins such as the negatively charged casein become neutralized. Now, as no negative charge is present on them so they start to crumple together rather then pushing each other apart. Hence, the clumping causes the milk to curdle in tea.
Answer:
because of the acidic nature of the lemon
