Which of the following quantities have the dimensions of an acceleration? which of the following quantities have the dimensions of an acceleration?
a. v²/x
b. xt²
c. x/t²
d. v/t

Explanation:

The acceleration of an object is given by :

Dimension of velocity is,      

Dimension of time is,        

Dimension of acceleration is,    

Option 1.

Option 2.

Option 3.

Option 4.

So, from above calculations, it is clear that option (1),(3) and (4) have the dimensions of acceleration. Hence, this is the required solution.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
