Correct option is

B

1m/s

2

in the given question we have

u=36 km/hr =36×

18

5

m/s=10m/s

v= 72 km/hr=72×

18

5

m/s=20m/s

t=10 s

a=?

we know the formula

v= u +at

20 = 10+ a 10

20-10 =10 a

10 = 10 a

a = 1 m/s

Why can an object still be seen when it is at absolute zero?
zavuch27 [327]
<span>As the temperature goes down, the chaotic motion (velocity) of atoms start decreasing. If the temperature hits the absolute zero (which, in reality, is impossible to achieve), the atoms of the body would freeze, making the body still and stiff. One thing to note here is that the atoms do not get destroyed when the temperature reaches the absolute zero. That is the reason why the object can still be seen when it is at absolute zero.</span>
