Answer:

Explanation:

As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

Playing a certain musical note on a trumpet

Virty [35]

Answer:

(1) Resonance

Explanation:

Resonance is the process whereby a system is set into vibration due to the vibration of a nearby system with larger amplitude. The frequency at which this vibration takes place is called the resonant frequency.

It is a phenomenon of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to the natural frequency of the system on which it acts.

What is the power generated by a 45 kg person who walks up a flight of 12 stairs, each 30 cm high, in 12 s?

Free_Kalibri [48]

The total distance covered by the person is 12 times the height of each stair:
$\Delta h=12 \cdot 30 cm=360 cm=3.60 m$

The work done by the person to climb the stairs is equal to the increase in his gravitational potential energy:
$W= \Delta U=mg \Delta h=(45 kg)(9.81 m/s^2)(3.60 m)=1589.2 J$

And therefore, the power generated by the person in 12 s is the work done divided by the time taken:
$P= \frac{W}{t}= \frac{1589.2 J}{12 s}=132.3 W$

So, the correct answer is B.

150kg object takes 1.5minutes to travel 2,500 meter straight path it begins the trip traveling 120m/s and decelerates to a veloc

Free_Kalibri [48]

<h2>Answer:</h2>

Acceleration= -1.11 m/sec²

<h2>Explanation:</h2>

Date Given to us is

Mass = 150 kg

Time = 1.5 minutes = 90 seconds

Distance = 2500 meters

Initial Velocity = 120 m/s

Final Velocity = 20 m/s

Acceleration = ?

<u>Solution:</u>

By using First Equation of motion

Vf = Vi + at

Putting the values

20 = 120 + a (90)

Subtracting 120 on both sides

20-120 = 120 + a(90) - 120

-100 = 90 a

Dividing both sides by 90

-100/90 = 90 a / 90

-1.11 = a

So the acceleration is -1.11 m/s²

A car is making a 60 mi trip. It travels the first half of the total distance 30.0 mi at 8.00 mph and the last half of the total

Alja [10]

Answer:

total time =4.583 hour

Explanation:

We have given total distance = 60 mi

It is given that half of the distance traveled by a speed of 8 mph

We know that $time\ t=\frac{distance }{speed}=\frac{30}{8}=3.75hour$

And second half of the distance traveled by a speed of 36 mph

So time $t=\frac{distance }{speed}=\frac{30}{36}=0.833hour$

So total time = 3.75 + 0.833 =4.583 hour
