Answer:

D

Explanation:

When the spring is wound, then it gathers potential energy in the form of tension energy. As it slowly unwinds, the potential energy is converted to kinetic energy of the hands' movements of the clock. This energy is channeled through the use of cogs/gears in the clock.

A wave has a frequency of 2 Hz. How many waves are produced in one minute?
Vlad1618 [11]

Answer:

see below

Explanation:

2 Hz, means 2 complete waves are produced in one second, so

2 waves ----- 1 second

2 x 60 -------1 x 60

120 waves ------60 seconds

SOMONE PLEASE HELP ASAP!!!!

Answer:

from vacuum to air

Explanation:

Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.

  • When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
  • Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.

The correct option must be from a less dense medium to a denser medium.

density of glass = 2500 kg/m³

density of air = 1.275 kg/m³

density of ice = 919 kg/m³

density of water = 1000 kg/m³

density of plastic = 940 kg/m³

density of vacuum = 6.5 x 10⁻²⁷ kg/m³

The two possible options are;

from ice to water

from vacuum to air

The difference in densities of ice and water is not larger compared to vacuum and air.

If you are required to choose two options, the two options are correct

But if it is only one option, then from vacuum to air is the correct answer.

Therefore, the correct option is from vacuum to air

Define upthrust simply (don't copy)​
EleoNora [17]

Upthrust is the force that is pushing you up. Kinda to stop you from sinking right into the Earth. Upthrust is simply any force that is causing something to be pushed upwards. Kinda like the opposite of gravity, which is pulling you down =]

Hope this helps ❤️
