Answer:

\beta= 51.65^{\circ}

F_r=19.35\ N

Explanation:

Given:

  • force acting to the horizontal right direction, F_1=10\ lbf
  • force acting -135° to the horizontal, F_2=25\ lbf
  • force acting 150° to the horizontal, F_3=5\ lbf

<u>Now the total components of force in the horizontal direction:</u>

F_H=F_3\cos 150^{\circ}+F_2\cos(-135^{\circ})+10

F_H=5\times cos150^{\circ}+25\times cos(-135^{\circ})+10

F_H=-12.0078\ N -ve sign means acting in negative x-axis

<u>The total vertical components in the vertical direction:</u>

F_v=5\times sin150^{\circ}+25\times sin(-135^{\circ})

F_v=-15.1776\ N -ve sign means acting in negative y-axis

Now the resultant:

F_r=\sqrt{F_H^2+F_v^2}

F_r=\sqrt{(-12.0078)^2+(-15.1776)^2}

F_r=19.35\ N

<u>The angle of the force:</u>

tan\ \beta=\frac{F_v}{F_H}

tan\ \beta=\frac{-15.1776}{-12.0078}

\beta= 51.65^{\circ}

3. How do astronomers explain the lack of a meteorite in Tunguska? What evidence exists to support this
Vaselesa [24]
No traces of a meteorite were found, it many scientists concluded that the culprit was a comet. Comets, which are essentially muddy ice balls, could cause such a devastation and leave no trace.

But now, 105 years later, scientists have revealed that the Tunguska devastation was indeed caused by a meteorite. A group of Ukrainian, German, and American scientists have identified its microscopic remains. Why it took them so many years makes for a fascinating tale about the limits of science and how we are pushing them.
