A mold fossil is a 3D example of an object, while a mold fills up with a sediment like mud. The mold fossil is related to the cast fossil because both can hold an organism or part of an organism.
Answer:
Particles of electromagnetic radiation exhibit wave behavior
Electromagnetic radiation includes visible light
The specific amount of energy a particular photon possesses is called a quantum
Explanation:
Electromagnetic waves propagate through space perpendicularly to a oscillating magnetic and electric field producing it. Both of these fields oscillates perpendicular to one another, and to the direction of propagation of the wave.
Electromagnetic waves exhibit both wave and particle light behaviors, this phenomenon is known as the wave-particle duality.
Visible light is part of the broad spectrum of waves in the electromagnetic wave spectrum. And each particle of an electromagnetic wave is known as a photon, and they carry energy in discrete amounts called quantum.
You didn't say so, but we must assume that the "200 km/hr" is
the glider's air-speed, that is, speed relative to the air.
If the air itself is moving at 30 km/hr relative to the ground and
across the glider's direction, then the glider's speed relative to
the ground is
√(200² + 30²)
= √(40,000 + 900)
= √(40,900) = 202.24... km/hr (rounded)
