Explanation:
a.) kg(m/s)(1/s) = force (N)
b.) (kg/s)(m/s) = force (N)
c.) (kg/s)(m/s) = force (N)
d.) (kg/s)(m/s) = force (N)
Answer:
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Wavelength can be defined as the distance from one peak to the next peak. Also, this distance is equal to the distance from one trough of a wave to another.
Mathematically, the speed of a wave is given by the formula;
V = fλ
Where;
V is the speed of the wave.
f is the frequency of the wave.
λ is the wavelength of the wave.
The speed of a wave (wave speed) is directly proportional to the frequency of a wave.
This ultimately implies that, an increase in the speed of a wave would cause an increase in the frequency of a wave and vice-versa.
The Law of reflection would still hold even off a curved surface. Since the angles are measured from the normal, which is perpendicular to the surface, curved surfaces don't matter. This is basis of curved mirrors such as concave and convex
Temperature will rise until reaching 0°C.
Answer:
Following are the answer to this question:
Explanation:
In option (a):
- The principle of Snells informs us that as light travels from the less dense medium to a denser layer, like water to air or a thinner layer of the air to the thicker ones, it bent to usual — an abstract feature that would be on the surface of all objects. Mostly, on the contrary, glow shifts from a denser with a less dense medium. This angle between both the usual and the light conditions rays is referred to as the refractive angle.
- Throughout in scenario, the light from its stars in the upper orbit, the surface area of both the Earth tends to increase because as light flows from the outer atmosphere towards the Earth, it defined above, to a lesser angle.
In option (b):
- Rays of light, that go directly down wouldn't bend, whilst also sun source which joins the upper orbit was reflected light from either a thicker distance and flex to the usual, following roughly the direction of the curve of the earth.
- Throughout the zenith specific position earlier in this thread, astronomical bodies appear throughout the right position while those close to a horizon seem to have been brightest than any of those close to the sky, and please find the attachment of the diagram.
