Answer:
The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.
There are three things that dictate how strong this field is:
1.How much kinetic energy you provide the wire
Answer is changed by pushing more current through the wire.
2. How permeable our magnetic rod is
Answer is changed by picking a more magnetic media
3.How many little magnetic fields you generate to make the net, large magnetic field
Answer is changed by increasing the amount of turns of the wire. More turns, more little fields, strong big field
Between noon and 2 pm, the amount of water in the rain gauge decreased.
This can be caused by evaporation, which turns water into water vapor.
Precipitation would increase the amount of rain water in the gauges, not decrease it.
Condensation occurs after evaporation but wouldn't decrease the water in the gauges by itself.
Runoff is when water on land drains into water sources such as lakes, rivers, oceans, etc.
So the answer is A. evaporation.
Answer: Particles cannot bend around the edges of an obstacle, as light waves does.
Explanation:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .When this occurs, the wave bends around the edges of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
Note this phenomenon is a characteristic of waves behaviour and not particles, because <u>particles cannot bend around the edges of an obstacle</u>, as waves (light waves in this case) does.
