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 ...

Time travel to cover 24 m with the speed of 4 metre per second, t₁ = 24/4 = 6 s Time travel to cover 32 m with the speed of 8 metre per second, t₂ = 32/8 = 4 ...

Total length of path covered by train = 400 + 150 = 550 m Train to cross the bridge (Find, Time Taken) = Total distance / speed = 550 / 50 = 11 s

On the sudden, application of break, the tanker will come in the state of rest but the water remains in the state of motion. So, the water will move forward.

Inertia of body is directly proportional to the mass of the body.

When we beat blanket with the help of stick, then it comes into motion. But the dust particles continue to be at rest due to inertia and get detached from the blanket.
