If light photons are massless then why are they attracted by black holes?

Answers

Answer 1

Answer:

Answer:

Photons have no mass, they do have energy, and the gravity of a black hole (or any other gravitating body) will attract them.

B. Switch

Explanation:

A device designed to open or close a circuit under controlled conditions is called a switch. The terms “open” and “closed” refer to switches as well as entire circuits. An open switch is one without continuity: current cannot flow through it.

Your grandmother in Ireland sends you her favorite cookie recipe. Her instructions say to bake the cookies at190.5°C. To what Fahrenheit temperature would you set the oven to bake the cookies?

Answers

$F=(9)/(5)C+32$

$F=(9)/(5)190.5C+32$

$F=342.9+32$

$F=374.9$

$374.9F=190.5C$

Answer:

350 Degrees Fahrenheit

Explanation:

A wave with a wavelength of 15 m travels at 330 m/s. Calculate its frequency.

Answers

Given the value of wavelength and speed at which the wave travels, the frequecy of the wave is 20 Hertz.

What is Wavelength?

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the wavelength, frequency and speed relation;

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

Wavelength λ = 15m
Speed of the wave v = 300m/s
Frequency f = ?

To determine the frequency of the wave, we substitute our given values into the expression above.

λ = v ÷ f

f = v ÷ λ

f = 300m/s ÷ 15m

f = 20s⁻¹

f = 20Hz

Given the value of wavelength and speed at which the wave travels, the frequecy of the wave is 20 Hertz.

Bats use ultrasound in echolocation. This sound is characterized by __low frequencylow amplitudehigh frequencyhigh amplitude

Answers

Bats use high frequency. Whenever somebody says a quantity is "high",
you have to ask "compared to what ?". In this case, it's compared to human
hearing ... we can't hear bats at all, or if we can, it just sounds like a 'click'.

Answer:

Both use reflected sound waves.
