why is the saturated lapse rate less than the dry adiabatic lapse rate?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.
Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.
WHAT IS THE VOLUME OF A 5.71 G PLASTIC CUBE THAT HAS A DENSITY OF 1.15 G/CM3
Answer:4.96[tex]cm^{3}[/tex]
Explanation: Density is [tex]\frac{Mass}{Volume}[/tex]
so you are now looking for volume.
Volume= Density x Mass so
Volume = (5.78g) x(1.15g/ [tex]cm^{3} \frac{x}{y}[/tex]) =4.96[tex]cm^{3}[/tex]

Explanation:
A 250 g sample of water with an initial temp of 98.8 c loses 7500 joules of heat. What is the final temperature of the water?
The final temperature of the water is 106.0 °C
From the question,
We are to determine the final temperature of water.
From the formula
Q =mcΔT
Where Q is the quantity of heat
m is the mass of substance
c is the specific heat capacity of substance
and ΔT is the change in temperature
Also,
ΔT = T₂ - T₁
Where T₂ is the final temperature
and T₁ is the initial temperature
Then, the formula can be written as
Q =mc(T₂ - T₁)
From the question
Q = 7500 J
m = 250 g
T₁ = 98.8 °C
Putting the parameters into the formula, we get
7500 = 250 × 4.184 (T₂ - 98.8)
(NOTE: specific heat capacity of water, c,= 4.184 J/g °C)
7500 = 1046 (T₂ - 98.8)
7500 = 1046T₂ - 103344.8
Then,
1046T₂ = 7500 + 103344.8
1046T₂ = 110844.8
∴ T₂ = 110844.8 ÷ 1046
T₂ = 105.9701 °C
T₂ ≅ 106.0 °C
Hence, the final temperature of the water is 106.0 °C.

a tennis ball is launched from the floor at a velocity of 90 m/a at an angle of 13 degrees to the horizontal. calculate its range
Answer:
~186
Explanation:
1) R= (V^2 × sin A ) /g
V=90 m/a
A= 13°
g= 9.8 or 10 (I will take 9.8 for right result)
R= (90^2 × sin 13) / 9.8 = 185.928932672 ~ 186

A force unit is defined as the product of a mass unit and a unit of
acceleration.
time.
velocity.
displacement.
Answer:
A force unit is defined as the product of a mass unit and a unit of acceleration.
Answer:
Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.
Explanation:
Force = M (Mass) * A (Acceleration)
The SI unit of Mass = KG
S.I. unit of acceleration is m/sec/sec = m/sec2
Hence, Unit of force is Kg m/Sec2
Since force is used so often, S. I. gives this unit a special name:
1 Newton = 1 kg m/sec2
If the wind is blowing from north to south, where are the areas of high and low pressure?
Answer:
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.
Our Earth is a rotating planet. Fast moving air is deflected by the Coriolis effect, except exactly on the equator. This defines the direction of cyclones, hurricanes, and typhoons rotation. The wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.
The high is west of you, and the low is east of you. (If you're in the northern Hemisphere.)

Apply Newton’s second law to calculate the frictional force needed to hold a 15 g pen in your fingers and keep it from falling
Answer:
0.1962N.
Explanation:
Weight is a force, so we use newtons second law which states F=ma. So the weight of a watermelon on earth is 2kg x 9.81m/s², which is 19.62N (newtons). On the moon it weighs 2 x 1.63 which is 3.26N.
The weight of the pen is 0.02 x 9.81, which is 0.1962N. If the pen is not to fall the frictional force needs to be equal to this force,
so the answer is 0.1962N.

An book fell from a shelf 1.5 meters from the ground. If it took the book 3 seconds to hit the ground, what was the velocity of the book?
The initial velocity of the book before its hits the ground is 14.2 m/s.
The given parameters;
height of the book above the ground, h = 1.5 mtime of motion of the book, t = 3 secondsThe initial velocity of the book is calculated as follows;
h = ut + ¹/₂gt²
where;
u is the velocity of the book1.5 = 3u + (0.5 x 9.8 x 3²)
1.5 = 3u + 44.1
3u = 1.5 - 44.1
3u = -42.6
[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]
Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

When a 12 newton horizontal force is applied to a box on a horizontal
table top, the box remains at rest. The force of static friction acting on
the box is .....
The force of static friction acting on the box is greater than the applied horizontal force.
Force is known to be the reason for motion according to Newton's first law of motion. An object will move when it has been acted upon by an external force.
In this case, a box lying on a table has been acted upon by an external force of 12 newton but the box remains at rest. This simply means that the applied force is less than the force of static friction acting on the box.

An automobile travels the first half of an 80.0 mi trip at 20.0 mi/h and the second half of the trip at 40.0 mi/h. What is the average speed for the entire trip?
This question involves the concepts of uniform speed motion and average speed.
The average speed for the entire trip is "26.67 mi/h".
First, we need to find out the total time taken for the entire trip. For that purpose, we will break the entire trip into two halves of uniform speed motion:
[tex]Total\ Time = t_1+t_2\\\\Total\ Time = \frac{s_1}{v_1}+\frac{s_2}{v_2}\\\\Total\ Time = \frac{40\ mi}{20\ mi/h}+\frac{40\ mi}{40\ mi/h}\\\\Total\ Time = 2\ h + 1\ h\\Total\ Time = 3\ h[/tex]
Now, the average speed for the entire trip will be:
[tex]Average\ Speed = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Speed =\frac{80\ mi}{3\ h}[/tex]
Average Speed = 26.67 mi/h

Which is true for every atom of an element?
A.
It can be seen with a magnifying glass.
B.
It is joined together with another atom.
C.
It has mass and volume.
D.
It is weightless.
Answer:
A
Explanation:
Every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.
What is the matter?Anything which has mass to keep the same when comparing the hardness of the solid and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
As given in the problem statement we have to find the true statement from the given options that is true for every atom of an element,
The size of an atom of an element is a very small order of magnitude so it can not be seen with a magnifying glass, therefore, option A is not the correct response.
Thus, every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.
