Answer:
<em> 3980.89 ohms</em>
Explanation:
The capacitive reactance is expressed as;
f is the frequency
C is the capacitance of the capacitor
Given
f = 60H
C = C1+C2 (parallel connection)
C = 15μF + 25μF
C = 40μF
C =
Substitute into the formula:
<em>Hence the total capacitive reactance is 3980.89 ohms</em>
<span><em>Continental drift</em> is one of the earliest ways that geologists thought <em>continents</em><span> moved
over time. It is believed in this theory that the Earth’s movement of the
continents are relative to each other.
This idea was subsumed by the plate tectonics theory. Now, what is the
speed of the continental drift?</span></span>
Continental drift speed is 1x 10^-9 m/s.
This is equivalent to a speed of:
1 x 10 ^-9 m/s
= 1 x 0. 000 000 000 1 m/s
= 0. 000 000 000 1 m/s
The period of the Sun's galactic motion: 2.26= years. The galaxy's rotation around its core, which all of its parts share to varied degrees.

What is galactic motion?</h3>
- The galaxy's rotation around its core, which all of its parts share to varied degrees. Most of the time, the motion of the galactic disc is circular and parallel to the galactic plane. Moving through the immensity of intergalactic space is the Milky Way itself.
- Our galaxy is a member of the Local Group, a collection of nearby galaxies, and as a group, we are lazily moving toward the cluster's nucleus at a speed of 25 miles per second. The galactic disk's gravity causes the Sun to oscillate every 64 million years, which is a much more accurate picture of the Sun's orbit around the Milky Way galaxy (though it is exaggerated vertically for clarity).

Answer:28 m
Explanation:
Given
Direction is North of east i.e. with x axis
Also ball moved by 33 m
therefore its east component is 33cos58=17.48 m
Northward component
