1. if the work done to move a box to a distance of 6 metres equals 120 joules. calculate the force

Serga [27]

Explanation:

1. W = F x D

F = W/D

F = 120/6 = 20Newton

2. P. E = mgh

P. E = 1.5x10x2 = 30Joules

3. It means that the energy the body possesses at that point is 20Joules

A tank whose bottom is a mirror is filled with water to a depth of 19.6 cm. A small fish floats motionless a distance of 6.40 cm

ANEK [815]

Answer:

A. 4.82 cm

B. 24.66 cm

Explanation:

The depth of water = 19.6 cm

Distance of fish = 6.40 cm

Index of refraction of water = 1.33

(A). Now use the below formula to compute the apparent depth.

$d_{app} = \frac{n_{air}}{n_{water}} \times d_{real} \\= \frac{1}{1.33} \times 6.40 \\= 4.82 cm.$

(B). the depth of the fish in the mirror.

$d_{real} = 19.6 cm + (19.6 cm – 6.40 cm) = 32.8 cm$

Now find the depth of reflection of the fish in the bottom of the tank.

$d_{app} = \frac{n_{air}}{n_{water}} \times d_{real} \\d_{app} = \frac{1}{1.33} \times 32.8 = 24.66\\$

In which of the following cases would sound reach each ear out of phase?

notsponge [240]

Answer:

Explanation:

Because when you stand directly near the source of sound the distance is less and sound is directly proportional to area.
