Answer: D. solids and liquids only

Explanation:

Solids have definite volume because they have almost no inter-molecular space between its molecule, they are closely packed and rigid in their structure and hence they also have a definite shape.

In case of liquids we have a little inter-molecular space which makes the liquid-bulk flexible enough to attain any shape but this inter molecular space is not sufficient enough to make them compressible making them negligibly compressible. Therefore liquids are also  considered to have a difinite volume.

But in the case of gases there is very large inter molecular space and the molecules make a random motion due to very weak force of attraction between them and the space between the molecules is compressible on the application of force. So, they don't have a definite shape and definite volume.

A car is being driven at a rate of 60 ft/sec when the brakes are applied. The car decelerates at a constant rate of 19
Hunter-Best [27]

The car will take 300 m before it stops due to applying break.

<h3>What's the relation between initial velocity, final velocity, acceleration and distance?</h3>
  • As per Newton's equation of motion, V² - U² = 2aS
  • V= final velocity velocity of the object, U = initial velocity velocity of the object, a= acceleration, S = distance covered by the object
  • Here, U = 60 ft/sec, V = 0 m/s, a= -6 ft/sec²
  • So, 0² - 60² = 2×6× S

=> -3600 = -12S

=> S = 3600/12 = 300 m

Thus, we can conclude that the distance covered by the car is 300 m before it stopped.
