What kind of wave exists when a musician plays a note on a trombone?
kykrilka [37]
The trombone is a wind musical instrument and as all musical instruments can produce a standing (or stationary) wave.

This kind of waves is the result of the composition of two waves that produces a pattern that looks like it is not moving but just vibrating. Some points of the wave look like they are not even vibrating, they just stand still, and they are called nodes. Other points of the wave vibrate from the maximum positive value to the maximum negative value and are called antinodes.

What are two reasons the period of Venus is shorter than the period of earth
Setler79 [48]

Answer: The planet, named after the Roman goddess of art and beauty, can actually be bright enough to cast shadows on a moonless night. It appears so close to the sun because its orbital radius is smaller than the Earth's, and because it also moves faster than Earth, its orbital period is shorter.

A spaceship accelerates uniformly for 1220km how much time is needed for the spaceship to increase its speed from 11.1km/s to 11
snow_lady [41]

The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s is 107 s

<h3>Data obtained from the question</h3>

The following data were obtained from the question given above:

  • Initial velocity (u) = 11.1 Km/s
  • Final velocity (v) = 11.7 Km/s
  • Distance (s) = 1220 Km
  • Time (t) =?

<h3>How to determine the time</h3>

The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s can be obtained as illustrated below:

s = (u + v)t / 2

Cross multiply

(u + v)t = 2s

Divide both sides by (u + v)

t = 2s / (u + v)t

t = (2 × 1220) / (11.1 + 11.7)

t = 2440 / 22.8

t = 107 s

Thus, the time taken for the spaceship to change its speed is 107 s
