If there is no difference in the dry and wet bulb, you can assume that the relative humidity is __________.a. 100%
b. 75%
c. 50%
d. 0% E. It cannot be determined.

Answers

If there is no difference in the dry and wet bulb temperatures,
you can assume that the relative humidity is 100% . . . since
no water was able to evaporate from the wet bulb.

Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below.A) Alice reaches the surface the lake first. B) Tom of reaches the surface of the first. C) Alice and Tom will reach the surface of the lake at the same time. D) Information is not enough

Answers

Answer:c

Explanation:

Given

Alice launches with horizontal velocity $u=25\ m/s$

Tom simply drops straight down from the edge

Time taken by both the person is same as they have same initial vertical velocity i.e. zero so the time taken to reach the ground is zero.

Although Alice will travel more horizontal distance compared to Tom.

Thus option c is correct

Which of the following is not one of da Vinci's contributions to technology?a. effect of the moon on tides
b. modern theory on the formations of the continents
c. precise observations of human anatomy
d. ideas for space travel

Answers

Answer: Option d: ideas of space travel.

Explanation:

Leonardo da Vinci was an Italian. He had numerous skills in various different fields. Leonardo contributed to technology for the effect of moon on the tides, his theory on formation of continents, human anatomy, art and much more. But he did not contribute in the ideas for space travel. Hence, the correct option is d.

Answer:D

Explanation:
