Question

on the
The position of a partice moving along
x- asis depends on the time
according to the equations = at + bts,
where x is
what are
co
in metre and t in second.
the units and dimensions
of as a and b.​

Answer 1

Answer:

i don't no sorry very sorry

Answer 2

The position of a particle moving along x-axis depends on time according to the equation x=at2+bt3,x=at2+bt3, where x is in metre and t is in sec. What are the units and dimensions of a and b : what do they represent?

Text Solution

Answer : 

ms−2,ms−2,LT−2;LT−3;a.ms-2,ms-2,LT-2;LT-3;a. 

and rate of change of acc.

Solution : 

x=at2+bt3x=at2+bt3 

Each term on RHS must have dimensions of x. 

Therefore, a=x/t2=m/s2=[LT−2]a=x/t2=m/s2=[LT-2] 

'a' represents acceleration. 

Also, b=x/t3=m/s3=[LT−3]b=x/t3=m/s3=[LT-3] 

∴'b'∴′b′ represents rete of change of 

acceleration with time.
