**Answer:**

B ) position

**Explanation:**

- speed shows how much of a distance the object is moving per unit time
- position is the place where the object is located
- acceleration is the rate of change of velocity of an object with the time
- applied force here means the force that is acting on the object

moving object can have a constant speed ,constant acceleration and no change in the applied force

(when there is no applied force on the object ,it keep its motion uninterruptedly - Newton's first law of motion )

But if an object is moving , it must change its position as if it is still remain in the same position , there can never be a motion at all

In an electric field force,F= q₁q₂/4πε₀ r² (coulomb's law) as we know,F=qE ** E=F/q**

**E=q/4πε₀ r²**

here,r= 0.0075 m

q= 0.0035 C

**1/4πε₀ = 9×10⁹**

E= 9×10⁹× 0.0035/(0.0075)²

=5.6 ×10¹¹ N/C

**Answer:**

Can help cure acne

**Explanation:**

Studies show that drinking more drinking water can help with blemishes on your face.

**Answer:**

The water usually rushes back too enthusiastically, causing a splash – and the bigger the rock, the bigger the splash. The splash then creates even more ripples that tend to move away from where the rock went into the water.

**Answer:**

**Explanation:**

As we know that the current through the battery is given as

here from above equation we know that current will become zero when time elapsed is very large

so here we can say that charge will flow through the battery from t = 0 to t = infinite

now we have

As we know that
