Asmall toy car travels 2.0 meters in 120 seconds. what is the speed of the car?

Explanation:

Speed of an object is defined as the ratio of the distance covered by the object to the time taken to cover that distance.

Let be the speed of the object.

Let be the distance travelled by the object.

Let be the time taken by the object.

So,

s=

So,the speed of the car is

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
