Answer:

D) in a cup of boiling water

Explanation:

The question is incomplete. The following options are missing:

A) in a bowl of hot soup

B) in a glass of iced tea

C) in a glass of tap water

D) in a cup of boiling water

The four options involve liquids (option B probably includes some ice and option D includes steam water). As temperature increase, the speed of the individual molecules of a substance also increases. Ordering the options by temperature, from the higher to the lower, we get:

D) in a cup of boiling water

A) in a bowl of hot soup (its temperature is above ambient but not enough to boil its water)

C) in a glass of tap water (ambient temperature)

B) in a glass of iced tea (below ambient temperature)

Therefore, in option D the molecules move faster.

Answer: Some conversions from one system of units to another need to be exact, without increasing or decreasing the precision of the first measurement. This is sometimes called soft conversion. It does not involve changing the physical configuration of the item being measured.

As mass increases what happens to the kinetic energy

AnnyKZ [126]

As mass increases kinetic energy also increases; kinetic energy is directly proportional to mass so whatever is done to either affects the other one the same. i hope this helps :)

You are a meteorologist. While taking present weather observations, you note that the sky is full of wispy cirrus clouds estimat

Goshia [24]

Answer:

It will take 60 hours to pass your area

Explanation:

From the question we are told that

The the distance of wispy cirrus clouds is $d_w =6km = 6*10^3 m$

The slope is given as $S = 1:300 = \frac{1}{300}$

The speed is $v = 40km/hour$

Since the slope is 1:300 which indicates the change in the distance of the wispy cirrus clouds overhead to the distance of the warm front

Now if

1 km → 300 km

Then

$8km$ → x km

Cross multiplying and making x the subject

$x = 8 *300 = 2400 \ km$

Velocity is mathematically denoted as

$velocity(v) = \frac{Distance(d) }{Time(t) }$

Now making time the subject

$Time (t) = \frac{Distance }{Velocity}$

Now substituting values we have

$t =\frac{2400}{40}$

$= 60\ hours$

Which is the correct product of the significant figures 3278 and 42?

Svetradugi [14.3K]

Answer:

$1.4\cdot 10^5$

Explanation:

In multiplications or divisions, the result must be written using a number of significant figures equal to the smallest number of significant figures contained in the original numbers.

For instance, in this case the two numbers are:

3278 --> 4 significant figures

42 --> 2 significant figures

So, the product must be written using 2 significant figures.

Calculating the product, we get:

$3278\cdot 42=137676$

Therefore, using 2 significant figures only, the result is

$1.4\cdot 10^5$
