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).      

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
