Answer:
wavelength.
Explanation:
One complete expression of a waveform beginning at a certain point, progressing through the zero line to the wave’s highest (crest) and lowest (trough) points, and returning to the same value as the starting point is called a is called wavelength. Its can be also defined as the distance between two successive crests or trough points in wave form.
Stratosphere is THE LAYER OF ATMOSPHERE THAT PROTECTS US because it contains OZONE. Ozone is also a layer that protects us from the direct rays/ UV RAYS of the SUN
Astronomers discover an exoplanet, a planet orbiting a star other than the sun, that has an orbital period of 4.50 earth years in a circular orbit around its star, which has a measured mass of 3.60×1030 kg.
The length of time it takes an astronomical object to complete one orbit around another object is known as the orbital period (also known as the revolution period). In astronomy, it typically refers to bodies like planets or asteroids revolving about the Sun, as well as moons circling other stars, exoplanets, and double stars.
A year refers to the orbital period of the Earth. A day is a period of rotation. 24 hours make up a solar day, although the Earth rotates around the sun by one degree every day. We can determine the orbital period by noting the interval between transits. If the mass of the orbiting star is known, one may use Kepler's Third Law to calculate the orbital radius of the planet (R3=T2Mstar/Msun; the radius is in AU and the period is in earth years).

Answer:
Explanation:
Using Newton's second law:
Where is the force applied on the object, is the mass of the object, and is the acceleration.
In this case we need the acceleration, so we clear for :
we know that the force is: , and the mass:
so the acceleration:
the acceleration of the block is:
