3. Will the weight of a kg of iron in air and the weight of a kg of cotton in air
larisa [96]

Answer:

A kg of cotton is heavier.

Explanation:

Because in air, cotton gets upthrust that's why weighing machine gives less weight than its actually have.

hram777 [196]

Answer:

20 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

r = Radius of robot = 0.5 m

\alpha = Angular acceleration = 2 rad/s²

Linear acceleration is given by

a=r\alpha\\\Rightarrow a=0.5\times 2\\\Rightarrow a=1\ m/s^2

s=ut+\frac{1}{2}at^2\\\Rightarrow 50=0t+\frac{1}{2}\times 1\times t^2\\\Rightarrow t=\sqrt{\frac{50\times 2}{1}}\\\Rightarrow t=10\ s

While speeding up time taken is 10 seconds

v=u+at\\\Rightarrow v=0+1\times 10\\\Rightarrow v=10\ m/s

s=ut+\frac{1}{2}at^2\\\Rightarrow 50=10t-\frac{1}{2}\times 1\times t^2\\\Rightarrow t=\sqrt{\frac{50\times 2}{1}}\\\Rightarrow 50=10t-0.5t^2\\\Rightarrow -5t^2+100t-500=0

t=\dfrac{-100\pm \sqrt{100^2-4\left(-5\right)\left(-500\right)}}{2\left(-5\right)}\\\Rightarrow t=10\ s

The time taken to slow down is 10 seconds

Total time the trial is rum is 10+10 = 20 seconds
