Science Component

Question 1

In the presence of starch, brown iodine solution turned dark blue. Mary tested some food with iodine and recorded the results in a table as shown below.

Based on the results, state the difference in the food that comes from plant and food comes from animals.

Question 2

When an object falls from a height, its gravitational potential energy transforms to kinetic energy.

The kinetic energy of an object can be calculated by using the formula:

The gravitational potential energy of the ball can be calculated by using the formula: 10mh, where m = mass, and h = height.

When an object is released from a height 4 times greater, what is the increase in its speed?

A v is 1.4 times greater

B v is 2 times greater

C v is 3 times greater

D v is 4 times greater
