A wire from the power supply is carrying 120w of power and 24a of current. which color(s) of cable is the wire

There is no picture given so I can't be really sure what color of the cable you're referring to. However, the only relationship I can think of when the power and the current is given would be: P=IV or P = I²R, where P is power, I is current, V is voltage and R is resistance. Solving both equations:

120 W = (24 A)(Voltage)
Voltage = 5 V

120 W = (24 A)²(R)
R = 0.2083 Ω

So, i think the cable would have specification of 5 Volts and 0.2083 ohms.

Answer and explanation;

Power = voltage × current;

P = V/I

Thus;

V = P/I

= 120W/24A

= 5V

The voltage is therefore; 5 volts

The wire color is either Red or White.

Moon diameter - 2,160 miles Sun diameter - 864,000 miles
So, in terms of diameter the Sun is 400 times bigger then the Moon. If we divide 150,000,000 km by 384,000 km we get 390.625 almost the same number.
The Sun and the Moon have sizes which vary a small amount as seen from Earth.
The Sun appears largest about January 4th and smallest around July 4th.

seropon [69]

Answer:

Part a)

$v = 7.94 m/s$

Part b)

$a = 992.6 m/s^2$

Explanation:

Part a)

As we know that we can use momentum conservation for this

so we will have

$m_1v_1 = (m_1 + m_2)v$

$(50m)8.1 = (50m + m)v$

$v = 7.94 m/s$

Part b)

As we know that acceleration is rate of change in velocity

so we have

$a = \frac{v_f - v_i}{t}$

so we have

$a = \frac{7.94 - 0}{8 \times 10^{-3}}$

$a = 992.6 m/s^2$

If you are anchored in a fixed spot, and a set of six waves pass underneath you during a 60 second time interval, what is the wa

Lunna [17]

Answer:

Explanation:

Six waves passes by under 60second interval

Since it has 6 waves,

Then, it correspond to 3 wavelength

Then,

The period of each Each wavelength is 60 / 3

Then, period = 20seconds

From the relationship between frequency and period

f = 1 / T

f = 1 / 20

f = 0.05 Hz

A car traveling at 91.0 km/h approaches the turn off for a restaurant 30.0 m ahead. If the driver slams on the brakes with the a

eduard

Answer: 49.92 m

Explanation:

In this situation the following equation will be useful:

$V^{2}=V_{o}^{2} +2 a d$

Where:

$V=0 m/s$ is the final velocity of the car, when it finally stops

$V_{o}=91 \frac{km}{h} \frac{1000 m}{1 km} \frac{1 h}{3600 s}=25.27 m/s$ is the initial velocity of the car

$a=-6.4 m/s^{2}$ is the constant acceleration of the car after the driver slams on the brakes

$d$ is the stopping distance

Isolating $d$ :

$d=\frac{-V_{o}^{2}}{2a}$

$d=\frac{-(25.27 m/s)^{2}}{2(-6.4 m/s^{2})}$

$d=41.919 m \approx 41.92 m$

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

lesantik [10]

Answer: The light bulb produces the continuous light. At minimum wavelength the spectrum have maximum intensity.

Explanation:

According to Wein's displacement law, the wavelength is inversely proportional to the temperature.

The intensity depends on the frequency. The frequency is inversely proportional to the wavelength.

Therefore, when the temperature of the light bulb will be maximum then the wavelength will be minimum. At minimum wavelength the spectrum have maximum intensity.
