At a point 1.2 m out from the hinge, 14.0 N force is exerted at an angle of 27 degrees to the moment arm in a plane which is per
geniusboy [140]

Answer:

\tau = 7.63 Nm

Explanation:

As we know that moment of force is given as

\tau = \vec r \times \vec F

now we have

\vec r = 1.2 m

\vec F = 14 N

now from above formula we have

\tau = r F sin\theta

here we know that

\theta = 27 degree

so we have

\tau = (1.2)(14) sin27

\tau = 7.63 Nm

Raindrops hitting the side windows of a car in motion often leave diagonal streaks even if there is no wind. Why? Is the explana
labwork [276]

Answer:

because of the raindrop velocity relative of the car has a vertical and horizontal component  

Explanation:

  1. The car moves in a <em>horizontal direction </em>relative to the ground. The raindrops fall in the <em>vertical direction</em> relative to the ground.
  2. Their velocity relative to the moving car has  both vertical and horizontal components and this is the reason for the diagonal streaks on the side window.
  3. The diagonal streaks on the windshield  arise from a different reason.
  4. The drops  are pushed  off to  one side  of the  windshield  because  of air resistance.

When an oxygen atom forms an ion, it gains two electrons. What is the electrical charge of the oxygen ion?
Damm [24]
The oxygen atom, before it gains these two electrons, has a neutral charge, meaning that it has as many protons as electrons. After it gains 2 electrons, it has 2 more electrons than protons. Each electron has a charge of -1, so the whole molecule will  have a charge of -2. The correct answer is a)!
