J(denoted byj) can be defined as a function of acceleration (denoted by a) and time (denoted by t) using this formula
j=a/t
acceleration is measured in m/s^2 and time is measured in s.
a= m^3/s^2
b= m^3/s^3
c=m/s^3
d=m/s^2

J = m/s³ ⇒ answer c

Step-by-step explanation:

* Lets explain how to solve the problem

- J (denoted byJ) can be defined as a function of acceleration

  (denoted by a) and time (denoted by t) using this formula  J = a/t

∵ j = a/t is a function of acceleration and time , where a is the

  acceleration and t is the time

- The acceleration is measured in m/s²

- The time is measured by the second

∵ The acceleration a = m/s²

∵ The time = s

- Substitute these values of acceleration and time in the function j

∴ J = m/s² ÷ s

- Change the division sign by the multiplication sign and reciprocal

  the term after the division sign

∴ J = m/s² × 1/s

- Remember that a^n × a^m = a^(n + m)

∵ s² × s = s³

∴ J = m/s³

Unit of J is .

Step-by-step explanation:

It is given that, J can be defined as a function of acceleration and time using this formula as :

Here, a is measured in and time is measured in s (seconds). We need to find the formula of J.

Since,

This gives,

So, the unit of J is m/s³. Hence, the correct option is (c).
