A van is traveling with an initial velocity of 12 m/s. The driver takes a time of 45 seconds to speed up to a velocity of 20 m/s
Rufina [12.5K]
  • Initial velocity=u=12m/s
  • Final velocity=v=20m/s
  • Time=t=45s

\\ \rm\hookrightarrow Acceleration=\dfrac{v-u}{t}

\\ \rm\hookrightarrow Acceleration=\dfrac{20-12}{45}

\\ \rm\hookrightarrow Acceleration=\dfrac{8}{45}

\\ \rm\hookrightarrow Acceleration=0.1m/s^2

Now

  • Distance=s

\\ \rm\hookrightarrow v^2-u^2=2as

\\ \rm\hookrightarrow (20)^2-12^2=2(0.1)s

\\ \rm\hookrightarrow 400-144=0.2s

\\ \rm\hookrightarrow 256=0.2s

\\ \rm\hookrightarrow s=\dfrac{256}{0.2}

\\ \rm\hookrightarrow s=1280m

Answer:

Chemical change

Explanation:

A chemical change is what happens. The food digested changes smell due to some enzyme the has acted on the food which catalyzes the rate of digestion. The enzymes acts on the food in order to speed up the rate of the reaction (digestion) and in turn causing the smell.

An iron nail is made up of particles. What is true about the particles?
nordsb [41]

Answer:

All these particles behaves like small magnets which is known as domains

Explanation:

As we know that iron is a ferromagnetic substance so in this type of ferromagnetic substance all the medium particles will behave like small magnets which is known as small domains.

These domains have their own magnetic field which is very weak but if all the domains will align in same direction then all domains will combined and give strong magnetic field.

So in general case when iron nail is placed at room temperature then all these domains are randomly arranged and they do not give any net magnetic field while if we place the iron nail in external magnetic field then in that case the domains will align itself and give strong magnetic field in the direction of external field.

This is known as magnetization
