The motor winds in the cable with a constant acceleration, such that the 20-kg crate moves a distance s = 6 m in 3 s, starting f
Marta_Voda [28]

Answer:

85 N

Explanation:

Given that crate mass = 20kg

Distance = 6m

Time = 3 seconds

Coefficient of kinetic friction = 0.3

We begin by calculating for acceleration

A student wrote the following statements about ocean waves. Statement 1: They have long wavelength. Statement 2: They are driven
Sergio039 [100]
The statements which best describe the properties of tsunami waves are these: 1. THEY HAVE LONG WAVELENGTH.
2. THEY TRAVEL AT VERY HIGH SPEED.
Tsunami typically occur as a result of sudden displacement of gigantic water masses which erupted due to earthquake that occur on the sea bed. One peculiar characteristic of tsunami is the very wide distances between its wavelengths. A tsunami is a very long wavelength waves of water, its wavelength is much more greater than that of ordinary wave and can be as much as 300 kilometer. 
 Wavelength is refers to the distance between two identical points on a wave, that is, between wave crests or wave troughs. 
Tsunami also travels at very high speed; it can travel for a long period of time at high speed without losing much energy.

What is Snell's Law?​
polet [3.4K]

Answer:

law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.

Snell's law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. ... Snell's law asserts that n1/n2 = sin α2/sin α1.

The following equation is an example of decay?<br><br> 232/90 TH---4/2 HE +228/88 RA?
DaniilM [7]

Answer:

Alpha decay

Explanation:

  • Alpha decay is one of the three major types of decays, others being, beta decay and gamma decay.
  • <em><u>When a radioactive isotope undergoes alpha decay it emits alpha particles. An alpha particle is equivalent to the nucleus of Helium atom.</u></em>
  • <em><u>Therefore, an atom undergoing decay, its atomic mass is decreased by 4 and its atomic number is decreased by 2. </u></em>
  • Thus, since 232/90 Th, has undergone alpha decay its mass number is reduced by 4 to 228 and its atomic number by 2 to 88, and becomes 228/88 Ra.
