The answer is B. Weak electrolytes are weak because they only partially dissociate into ions in water.
Hope this helps!
The tension in the cable is equal to 323.5 N.
<h3>What is the tension in the cable?</h3>
The tension, T in the cable is determined by taking moments about the pivot marked X.
The angles of the boom and the cable with the horizontal are first calculated.
Angle of the boom with horizontal, θ = tan⁻¹(5/10) = 26.56°
The angle of cable with horizontal, B = tan⁻¹(4/10) = 21.80
Taking moments about the pivot:
175.5 * cos 26.56 + 94.7 * cos 26.56 * 0.5 = T (sin(26.56 + 21.80) * 1
Tension = 241.68/0.747
Tension = 323.5 N
In conclusion, the tension in the cable helps to suspend the crate.

Answer:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
Explanation:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
This is due to the equinoxes. An equinox is an event that occurs twice a year. During these seasons all areas of the Earth's surface experience an equal amount of daylight and darkness. The sun is on the equator line, so the day and night in both hemispheres have the same duration. At that time the part of the Earth closest to the Sun is the equator.
The shape of the Earth means that while the spring equinox is experienced in the northern hemisphere, the autumn equinox is entered in the southern hemisphere.
