Plz help me in sloving calculation

The Acceleration of the object is 2 m/s².

Step-by-step explanation:

Given :

Initial velocity = 10 m/s

Final velocity = 20 m/s

Time taken = 5 seconds

To find:

The acceleration of the body

Solution :

v = 20

u = 10

t = 5

a = Acceleration

\boxed{\tt{a = \frac{v - u}{t}}}a=tv−u

⇒ a = \tt{ \dfrac{20 - 10}{5}}520−10

⇒ a = \tt{\dfrac{10}{5}}510

⇒ a = 2

Acceleration = 2 m/s²

Therefore, the Acceleration of the object is 2 m/s².

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

i believe the answer is true.
