a car dealer sells 4 makes of cars in 5 colors with either standard or automatic transmissions. how many variations does the dea
Anuta_ua [19.1K]

<u>The number of variations the dealership have is 40 cars</u>.

Data given;

  • The number of different product = 4
  • The number of transmission = 2 (standard or automatic)
  • The numbers of colors available = 5

<h3>Dealership variation </h3>

This is the total numbers of cars available in the dealer shop at the moment.

To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.

This is equal to

4*2*5=40

From the above calculation, we can say that <u>the variations the dealership offers is 40</u>

What is the average power supplied by a 60.0 kg secretary running up a 4.0 m tall flight of stairs in 4.2 s?
Alchen [17]

A 60.0 kg secretary running up a 4.0 m tall flight of stairs in 4.2 s has an average power of 560 W (Option b).

<h3>What is power?</h3>

Power is the work done over a period of time.

A secretary with a mass (m) of 60.0 kg runs up a 4.0 m (d) tall flight of stairs. Given gravity (g) is 9.81 m/s², the work (W) done is:

W = m × g × d = 60.0 kg × 9.81 m/s² × 4.0 m = 2.35 × 10³ J

They do 2.4 × 10³ J of work in 4.2 s (t). The average power (P) is:

P = W / t = 2.35 × 10³ J / 4.2 s = 560 W

A 60.0 kg secretary running up a 4.0 m tall flight of stairs in 4.2 s has an average power of 560 W (Option b).

what of instead of other forms of energy we use sound energy to power every thing since sound is there every where
Bad White [126]

So is light, but we don't use light either to power anything, even though we do know how to capture them and extract their energy.

The reason we don't use sound or light as sources of energy is because the amount of energy in the sound and light that surrounds us is pitifully small ... in the milliwatts or microwatts, whereas the things we build and operate with oil or electricity need watts or kilowatts to function.

1 watt of sound will drive you out of the room and wake the neighbors, and 1 watt of light ... if it all enters your eye ... can permanently damage your sight.
