**Answer:**

The converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller.

**Explanation:**

Diverging lenses are placed in the path of a beam of parallel rays that allow the rays to diverge after refraction.

Glasses use diverging lenses to correct for nearsightedness a diverging lens will diverge light before it reaches the eye.

Farsightedness refers to the inability to see close objects for which a converging lens is required to increase power.

In the given situation,

<u>the converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller</u>

Let the cold water go up x degrees.

Let the hot water go down 100 - x degrees.

The formula for heat exchange is m*c*delta t

**Givens**

Ice

deltat = x

m = 0.50 kg

c = 4.18

Hot water

deltat = 100 - x

m = 1.5 kg

c = 4.18

**Formula**

The heat up = heat down

0.50 * c * x = 1.5 * c * (100 - x) Divide both sides by c

**Solution**

0.50 *x = 1.5*(100 - x) Remove the brackets.

0.5x = 150 - 1.5x Add 1.5x to both sides.

0.5x + 1.5x = 150 - 1.5x + 1.5x Combine like terms

2x = 150 Divide by 2

x = 75

**Answer:**

**Equal to change in momentum of larger mass.**

**Explanation:**

We are given that

Two difference masses .

Force act on both masses for the same length of time.

We have to find the change in momentum of the smaller mass.

Let M and m are two masses

M>m

We know that

Change in momentum for large mass=

Change in momentum for small mass=

Because Force and length of time are same for both masses .

Hence, the change in momentum of smaller mass is equal to **change in momentum of larger mass.**
