Answer:
<h2>
14.4 m</h2>
The distance covered by the body is <u>1</u><u>4</u><u>.</u><u>4</u><u> </u><u>m</u><u>.</u>
<u>Sol</u><u>ution</u><u>,</u>
Initial velocity(u)= 0 m/s( according to Question, the body starts from rest.that's why initial velocity(u) becomes zero.
Acceleration (a)= 0.2 m/s
Time (t):


Now,
Applying third equations of motion:

Thus, the distance covered by the body is 14.4 metre.

- When a certain object comes in motion from rest, in the case, initial velocity(u)= 0 m/s
- When a moving object comes in rest,in the case, final velocity(v)= 0 m/s
- If the object is moving with uniform velocity, in the case, (u=v)
- If any object is thrown vertically upward, in the case, acceleration (a)= -g
- When an object is falling from certain height, in the case, u= 0 m/s
- When an object is thrown vertically upwards in the case, final velocity at maximum height becomes 0.
Answer:
Reactants are initiators of a chemical reaction whereas products are substances produced as the end of that reaction.
Explanation:
In a chemical reaction, there are two categories of substances involved: reactants and products.
The reactants are those substances utilized in a chemical reaction which undergo certain changes to produce different substances at the end of the reaction known as products.
On can write a chemical equation as:
M+N→MN, where M and N are the reactants and MN is the product.
For example,
Zn + S → ZnS
|___| ↓
Reactants Products
As you can notice when writing a chemical equation, reactants are always written on left hand side of the arrow and the products on the right hand side.
Answer:
500 J.
Explanation:
Work done = force * distance
= 25 * 20
= 500 Joules.
