Why does putting baking soda on a fire put it out?

1 answer:

Hii there,
Baking soda produces carbon dioxide when extinguishing a fire as only oxygen is needed for the fire to light up and carbon dioxide puts it off.

Hope this helps :))

A transformer has two sets of coils, the primary with N1 = 160 turns and the secondary with N2 = 1400 turns. The input rms volta

vovikov84 [41]

To solve the problem it is necessary to apply the concepts related to the voltage in a coil, through the percentage relationship that exists between the voltage and the number of turns it has.

So things our data are given by

$N_1 = 160$

$N_2 = 1400$

$\Delta V_{1rms} = 62V$

PART A) Since it is a system in equilibrium the relationship between the two transformers would be given by

$\frac{N_1}{N_2} = \frac{\Delta V_{1rms}}{\Delta V_{2rms}}$

So the voltage for transformer 2 would be given by,

$\Delta V_{2rms} = \frac{N_2}{N_1} \Delta V_{1rms}$

PART B) To express the number value we proceed to replace with the previously given values, that is to say

$\Delta V_{2rms} = \frac{N_1}{N_2} \Delta V_{1rms}$

$\Delta V_{2rms} = \frac{1400}{160} 62V$

$\Delta V_{2rms} = 1446.66V$

Which of these is an example of acceleration? A a bicyclist turning around a corner B a car traveling south with its cruise cont

Airida [17]

The answer is A.

Acceleration means when you go faster in speed. Since the bicyclist is turning, he has to slow down but when he finishes turning, he is going to pedal harder and gain more speed. This is called Acceleration.

Best of Luck!

An astronaut sings a song upon arriving on Planet Mongo. When her vocal cord produces an oscillation at 600 Hertz, she detects t

Paraphin [41]

The speed of sound on planet is 210 m/s.

<h3>What is Oscillation?</h3>

Oscillation is the repeating or periodic change of a quantity around a central value or between two or more states, often in time. Alternating current and a swinging pendulum are two common examples of oscillation.

There are 3 main types of Oscillation –

Free
damped
forced oscillation

f = frequency = 600 Hz

lambda = wavelength = 35 cm = 0.35 m

Now,

V = speed = f × lambda = 210 m/s

Hence, speed of sound on planet is 210 m/s.

Light travels at the speed of approximately 3.0 × 108 meters per second. Find the time in minutes required for light to travel f

Solnce55 [7]

Answer:

t = 8.33 minutes

Explanation:

given,

Speed of Light, v = 3 x 10⁸ m/s

distance between sun to Earth = 1.5 x 10¹¹ m

time taken to reach earth = ?

we know,

Distance = speed x time

$t = \dfrac{d}{s}$

$t = \dfrac{1.5\times 10^{11}}{3\times 10^8}$

t = 500 s

1 min = 60 s

now, $t = \dfrac{500}{60}\ minutes$

t = 8.33 minutes

time taken by the light to reach earth is equal to 8.33 minutes.
