We know that centripetal acceleration is nothing but the ratio of the square of the tangential velocity to that of the radius vector.
a=v*v/r=ωωrr/r
=ωωr
=2πf2πfr
=2π2πr/TT
=97m/secsec
Answer:
Mass of the second block is 1.4 kg
Explanation:
When a weight (mg) is displaced from its equilibrium position in a spring mass system, a restoring force (kx) will act on the weight.
so, mg = -kx
where, k is a constant
Mass of block () = 0.70 kg
For one spring mass system,
For the two spring mass system,
divide equation 2 by 1
on further rearranging,
So, mass of the second block is 1.4 kg.
Answer:
Explanation:
There are two main ways to de-starch leaves of a plant - the 'Light Exclusion' Method and the 'Carbon Dioxide Deprivation' Method. The 'Light Exclusion' method is a simpler procedure and is used often. Leaves can be destarched by depriving them of light for an extended period of time, usually 24-48 hours.
i believe the answer would be C.
Hope this helps!
