Astronomers are getting information about dark energy from
Thepotemich [5.8K]

The only way of telling about dark energy is our observation of how the universe has been expanding. It basically works the opposite as gravity, pushing things away from it. Thus, the closest answer would be D. The shape of galaxies in cluster galaxies.

A student uses the right-hand rule as shown.
Kipish [7]

Answer:

right is the correct answer to the given question .

Explanation:

In this question figure is missing

The main objective right-hand rule to decide the position of the magnetic force on the positive force acting, either the position of the thumb of a right hand with in position of v, the fingers throughout the position of B1, and a right angles throughout the position of F1 to the hand positions.

So    F1 \ =\ q\ v \ B1\ Sin\alpha

  • So from the magnetic right hand rule the direction of the magnetic field in front of a wire is right .
  • All the others options are incorrect because they do not give the direction of the magnetic field in front of a wire is right .

A wave has a wavelength of 125 meters is moving at a speed of 20 m/s. What is it’s frequency?
Ann [662]

Answer: 0.16Hz

Explanation:

Given that:

wavelength (λ) = 125 meters

speed (V) = 20 m/s

frequency (F) = ?

Recall that frequency is the number of cycles the wave complete in one second. And its value depends on the wavelength and speed of the wave.

So, apply the formula V = F λ

Make F the subject formula

F = V / λ

F = 20 m/s / 125 meters

F = 0.16 Hz

Thus, the frequency of the wave is 0.16 Hertz.
