Answer:

a transverse wave consisting of changing electric fields and changing magnetic fields

Explanation:

Electromagnetic waves are waves consisting of changing electric fields and magnetic fields oscillating perpendicularly to each other.

Moreover, the electric and the magnetic field oscillate in a plane perpendicular to the direction of propagation of the wave: for this reason, we say that electromagnetic waves are transverse waves.

All electromagnetic waves travel through a vacuum at the same speed, called speed of light, whose value is approximately

$c=3\cdot 10^8 m/s$

Moreover, electromagnetic waves are classified into 7 different types according to their different wavelengths. From shorter to longer wavelengths, these types are called:

Gamma rays

X-rays

Ultraviolet

Visible light

Infrared

Microwaves

Radio waves

The children at the local park think the slide is too slow. There is too much fiction. What could you do to decrease the amount

igor_vitrenko [27]

In order to decrease the friction on the slide,
we could try some of these:

-- Install a drippy pipe across the top that keeps continuously
dripping olive oil on the top end of the slide. The oil oozes
down the slide and keeps the whole slide greased.

-- Hire a man to spread a coat of butter on the whole slide,
every 30 minutes.

-- Spray the whole slide with soapy sudsy water, every 30 minutes.

-- Drill a million holes in the slide,and pump high-pressure air
through the holes. Make the slide like an air hockey table.

-- Keep the slide very cold, and keep spraying it with a fine mist
of water. The water freezes, and a thin coating of ice stays on
the slide.

-- Ask a local auto mechanic to please, every time he changes
the oil in somebody's car, to keep all the old oil, and once a week
to bring his old oil to the park, to spread on the slide. If it keeps
the inside of a hot car engine slippery, it should do a great job
keeping a simple park slide slippery.

-- Keep a thousand pairs of teflon pants near the bottom of the ladder
at the beginning of the slide. Anybody who wants to slide faster can
borrow a set of teflon pants, put them on before he uses the slide, and
return them when he's ready to go home from the park.

The two-second rule applies to any speed __________ A. in all weather conditions. B. in ideal weather and road conditions. C. in

kumpel [21]

Answer:

The answer is A

Explanation:

A large risk of tailgating is the collision avoidance time being much less than the driver reaction time. Driving instructors advocate that drivers always use the "two-second rule" regardless of speed or the type of road. During adverse weather, downhill slopes, or hazardous conditions such as black ice, it is important to maintain an even greater distance.
