The speed of light is the speed all waves travel ?
No, only the speed of all electromagnetic waves.
It's different for ocean waves, rope waves, sound waves,
guitar-string waves, slinky waves, etc.

The speed of light is the speed electromagnetic waves travel ?
Yes. Light is one of the electromagnetic waves.

The speed of light is 3.0 x 108 m/s in space ?
Yes. That's a good approximation, and a nice easy number
to remember.
It's only about 0.07% faster than the real number: 2.99792458 x 10⁸ m/s .

The speed of light is the same in all matter ?
No. It's different in every substance, and the speed in any
substance is less than the speed in space (vacuum).

The speed of higher frequency light slows down
more than lower frequency light in matter ?
Yes, slightly. That's why the colors spread out on the way
through a prism to make a spectrum, or on the way through
raindrops to make a rainbow.

A car of mass m goes around a banked curve of radius r with speed v. If the road is frictionless due to ice, the car can still n

Sholpan [36]

Answer:

horizontal component of normal force is equal to the centripetal force on the car

Explanation:

As the car is moving with uniform speed in circle then the force required to move in the circle is towards the center of the circle

This force is due to friction force when car is moving in circle with uniform speed

Now it is given that car is moving on the ice surface such that the friction force is zero now

so here we can say that centripetal force is due to component of the normal force which is due to banked road

Now we have

$N sin\theta = \frac{mv^2}{R}$

$N cos\theta = mg$

so we have

$v = \sqrt{Rg tan\theta}$

so this is horizontal component of normal force is equal to the centripetal force on the car

Suppose that a sound wave has a wavelength of 12 meters and a frequency of 100Hz. What is the speed of sound

Vesna [10]

Answer:

1200Hz

Explanation:

You would have to multiply 12 by 100 to get the answer.

12 • 100 = 1200 Hz

I hope it helps! Have a great day!
