1. How is a whistling teapot like a volcano?

Because of the build up of pressure. There is so much steam coming from such a compressed point, it’s coming out in force.

Now think of that same spot being closed, it only has one place to go but it can’t leave, so that pressure will build and build and then BOOM, it explodes.

In short, the answer is the pressure being released from a small point, and how that energy is released.

Answer:

It isn't exactly known what causes the harmonic tremor or small earthquakes, but Hotovec-Ellis' belief is that they are caused by magma being forced through narrow channels in the Earth sticking to rock surfaces along the way. When it sticks, it takes a buildup of pressure to push it along further.

Here is something to blow your mind. In one slice of "everything" pizza there are 650 Calories (1000 chemistry calories). That e

Answer:

Number of slices of pizza is 993.

Explanation:

It is given that, in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :

1 calorie = 4.184 joules

650 calories = 2719.6 joules

Total energy in the pizza, E = 2700000 J

Let there are n number of slices of pizza. It is given by :

$n=\dfrac{2700000}{2719.6}$

n = 992.79

n = 993

So, there are 993 slices of pizza. Hence, this is the required solution.

If C moves to position 5 (60 meters), what is its average velocity during these 5 seconds?

Hoochie [10]

Velocity:

60 meters/ 5 seconds= 12 meters/second

Velocity=12meters/second

(60 meters divided by 5 seconds equals 12 meters per second)

Hope this helps!

How do air mass conditions ahead of the squall line support the development of new cell?

IRISSAK [1]

<span>Storm cells in a squall line typically move from the southwest to the northeast, and as the mature cells in the northeast begin to die off, new ones are formed at the opposite end to advance the line. The air in the southwest corner has strong vertical updrafts that allow new cells to grow and develop into thunderstorms.</span>

Students in an introductory physics lab are producing a region of uniform electric field by applying a voltage to two 20-cm-diam

earnstyle [38]

Answer:

69000 V

Explanation:

E = Electric field = $3\times 10^6\ V/m$

d = Distance between plates = 2.3 cm

When we multiply the electric field strength and the distance between the plates of a capacitor we get the maximum voltage.

Maximum voltage is given by

$V_m=Ed\\\Rightarrow V_m=3\times 10^6\times 2.3\times 10^{-2}\\\Rightarrow V_m=69000\ V$

The highest voltage the students can use is 69000 V
