3.

When speed remains constant, velocity

may change

remain constant

must changes

slightly increases

a

4.

If Pressure of a fixed amount of gas is denoted as 'P' and volume is denoted as 'V' then Boyles law can be expressed as

P = k × V (where 'k' is a proportionality constant)

P = k ⁄ V (where 'k' is a proportionality constant)

P = k × V² (where 'k' is a proportionality constant)

P = k ⁄ V² (where 'k' is a proportionality constant)
