Answers

Answer 1
Answer: Radio Telescopes measures the galaxy's distribution of stars, galaxies, blackholes and other astronomical objects. It is used to study naturally -occuring radio light which is emitted by these astronomical bodies. Radio observatories are located far away from major cities to avoid electromagnetic interference from radio, televisions and radar.
Answer 2

A wave has a speed of 23 m/s and a frequency of 13 Hz. What is the wavelength?

Answers

Answer:

1.76923077 meters

Explanation:

wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz

Which type of waves is important to have for a surfer who wants to do aerial maneuvers? A. Plunging waves B. Surging waves C. Orbital waves D. Spilling waves

Answers

Plungingwaves is important to have for a surfer who wants to do aerial maneuvers.

The correct options is A.

What is a plunging wave?

When the ocean floor is steep or has abrupt depth changes, crashingwaves occur. They could be large close-outs or strong barrels. Combining pouring and plungingwaves creates a collapsing wave.

What causes plunging waves to form?

When the incoming surf strikes a steep ocean floor or a sea bottom with abrupt depth changes, plungingwaves are created. The wave's peak curves over and erupts on the trough as a result. A crashing sound is frequently audible due to the compression of the airbeneath the wave's lip.

Aerial maneuvers in surfing demand taking the surfboard into the air. The best type of waves for such maneuvers are:

- the section of a wave coming towards you should be  smaller than the section you are on

- you should try to find closeout sections of waves (  formations that do not allow a tubular ride )

- the wave should be either wedging or bowling in towards you, it should not be a straight wave.

The speed you read on a speedometer is______

Answers

The speed you read on a  speedometer is instantaneous.

Final answer:

The speed you read on a speedometer is your instantaneous speed, which is the speed your vehicle is moving at a specific moment. This is usually measured in miles per hour (mph) or kilometers per hour (km/h), and it's calculated based on the rotation of your vehicle's wheels or drive shaft.

Explanation:

The speed you read on a speedometer is your instantaneous speed. This is the speed at which your vehicle is moving at a specific moment in time. On a standard speedometer, you'll see this represented as miles per hour (mph) or kilometers per hour (km/h), depending on your location and the standard measure of distance in your country.

The speedometer works by taking into account the rotation of the wheels or drive shaft and converting that rotational speed into a speed of linear motion.

For example, if you're driving and your speedometer says 60 mph, this means that at that particular moment, you are moving at a speed of 60 miles in one hour.
