The flexibility in plants is due to Collenchyma. It also provides mechanical support to plants.

Given, s = ct₂ Here, c = constant of proportionally Acceleration, a = d₂s/dt₂ = d₂/dt₂ (ct₂) = 2c = constant So, the object is moving with a uniform acceleration.

a = dv/dt The increase in speed = (30 -12) = 18 m/s. Then, A = 18/15 = 1.2 metre per second square

In constant speed, acceleration does not change. So, it covers equal distances in equal time intervals.

Let “s” be total displacement, then s/2 = V⁰ t₁ or t₁ = s / 2V⁰ and, s/2 = V₁ t₂ + V₂t₃ = (V₁ + V₂) t₂ To find, Average velocity = Total displacement / Total time (should be ...
