Answers
Answer:
4)Food remains safe at 5 degree Celsius as it prevents the growth of bacteria. Explanation: Food is perishable, meaning it tends to deteriorate in quality as time goes by, and it would be unusable after the date of expiry.
5)The force gravity exerts on a person determines the person's weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.
6)Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
7)Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body
8)When a body falls freely to the ground, it is said to be in free fall. In free fall the acceleration experienced is that of the gravitational force, equivalent to 9.8m/s2. The body is thus said to be uniformly accelerated
