A mature thunderstorm will contain both updraft and downdrafts. The given statement is true.

When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.

This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.

How does a mirage occur in a deser?explain with a labelled diagram.

Ronch [10]

Answer:

Mirages happen when the ground is very hot and the air is cool.

Explanation:

They happen when light passes through two layers of air with different temperatures. The desert sun heats the sand, which in turn heats the air just above it. The hot air bends light rays and reflects the sky.

When you see it from a distance, the different air masses colliding with each other act as a mirror.

The engine in an imaginary sports car can provide constant power to the wheels over a range of speeds from 0 to 70 miles per hou

kirill115 [55]

Answer:

Part A

it would take 6 sec

it would take 3 sec

Explanation:

We are told that the power supplied to the wheel is constant which means that the sport car is gaining energy i.e

$power \ \alpha \ energy$

Hence if power is constantly supplied energy constantly increase

From the formula of the Kinetic energy

$KE = \frac{1}{2} mv^2$

we can see that as the speed doubles from 29 mph to 58 mph the energy needed is $2^2$ = 4 times of the energy from the formula

Also the time needed would also be 4 times because energy i directly proportional to time

Hence to reach 58mph the time that it would take is

= $4* 1.5sec = 6sec$

We are told that the ground pushes the car with a constant force and

F = ma

this means that the acceleration is also constant

now from newtons law

v = u +at

Looking at it we see that final velocity is directly proportional with time

hence it would take twice the time to reach twice the final velocity

Time to reach 58mph = 3 s

since time to reach 29 mph( $\frac{1}{2} \ of \ [58mph]$ ) =( $\frac{1}{2} \ of \ 3sec$ )1.5 s

Five liters of air at 50 c is warmed to 100c what is the new volume if the pressure remain constant

KonstantinChe [14]

To solve the problem, we can use Charle's law, which states that for an ideal gas at constant pressure the ratio between absolute temperature T and volume V remains constant:
$\frac{T}{V}=k$
For a gas transformation, this law can be rewritten as
$\frac{T_1}{V_1}= \frac{T_2}{V_2}$ (1)
where 1 and 2 label the initial and final conditions of the gas.

Before applying the law, we must convert the temperatures in Kelvin:
$T_1 = 50^{\circ}C + 273 = 323 K$
$T_2 = 100^{\circ}C+273=373 K$
The initial volume of the gas is $V_1 = 5 L$ , so if we re-arrange (1) we find the new volume of the gas:
$V_2 = V_1 \frac{T_2}{T_1}=(5 L) \frac{373 K}{323 K}=5.77 L$

Object A has a mass of 8.0 kg and is accelerating at 4.0 m/s2. Object B has a mass of 10.0 kg and is accelerating at 3.0 m/s2. O

Leviafan [203]

Answer:

b. B, A, C

Explanation:

To solve this problem, let us find the net forces they are experiencing.

Net force = mass x acceleration

Object A; mass = 8kg and acceleration = 4m/s²

Net force = 8 x 4 = 32N

Object B; mass = 10kg and acceleration = 3m/s²

Net force = 10 x 3 = 30N

Object C: mass = 7kg and acceleration = 5m/s²

Net force = 7 x 5 = 35N

So, increasing order of their net force;

B < A < C
