Answer:

2 * 10^4

Explanation:

(3 * 10^4)(4 * 10^4) / (6 * 10^4)

= (12 * 10^8)/(6 * 10^4)

= 2 * 10^4

<h3>What are the color of bears?</h3>

Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.

The color of bears, may be brown, black or white depending on how far North the bears are found.

Bears found close to the Arctic or North pole are white polar bears.

Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.

Therefore, the color of the bear will be white.

In a transformer a 120 volt dc Primary of 500 turns is connected to a secondary of 75 turns. What is the Induced voltage in the

oee [108]

Answer:

The induced voltage in the Secondary is 18 volt.

Explanation:

Given that,

Voltage = 120 volt

Number of turns in primary = 500

Number of turns in secondary = 75

We need to calculate the induced voltage in the Secondary

Using relation number of turns and voltage in primary and secondary

$\dfrac{V_{p}}{V_{s}}=\dfrac{N_{p}}{N_{s}}$

Where, $N_{p}$ = Number of primary coil

$N_{s}$ = Number of secondary coil

$V_{p}$ = Voltage of primary coil

Put the value into the formula

$\dfrac{120}{V_{s}}=\dfrac{500}{75}$

$V_{s}=\dfrac{120\times75}{500}$

$V_{s}=18\ Volt$

Hence, The induced voltage in the Secondary is 18 volt.

natima [27]

Answer:

Nature of Sound Waves Sound is a wave that is created by perturbations and propagated through a medium from one location to another. Type of Wave: longitudinal wave. A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a medium of propagation and a disturbance. Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. Anatomy of a Wave:

SpyIntel [72]

D. When velocity at a maximum, acceleration is also at a maximum.

Acceleration is the rate of change of velocity so, it is directly proportional to it, hence, when it will increase velocity will also increase

Hope this helps!
