Answer:
Explanation:
19116 being the distance from the centre of the earth to the point you want to check in metres. So after all that you get G = 1.0888m/second squared. Hope that helps you/ you should be able to pop in any height you want.

I think Y is the answer to number 4
Answer:
Option D.
A fan is turned from high speed to low speed.
Explanation:
It is important to note that air is also a fluid.
In a system, static pressure of air increases with the speed of rotation of the fan. This is because when the speed of the fan is increased, the force with which it is pushing the air molecules is increased. Since pressure is a relationship between force and area, the pressure of the air molecules will be increased.
Conversely, when the speed of the fan is reduced, the priming force on the air molecules will be reduced, hence the pressure of the air will drop.
This makes option D the correct option
The LC circuit will also need a capacitance of 1.01 μF.
<h3>
What is capacitance?</h3>
Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.
<h3>Capacitance needed for the resonance circuit</h3>
Xl = Xc
where;
- Xl is the inductive reactance
Xl = ωL
Xc = 1/ωC
ωL = 1/ωC
ω²LC = 1
C = 1/(ω²L)
C = 1/(2πf)²(L)
C = 1/(4π²f² L)
C = 1/(4π² x 100² x 2.5)
C = 1.01 x 10⁻⁶ F
C = 1.01 μF
Thus, the LC circuit will also need a capacitance of 1.01 μF.

The resultant of the two vectors is 141 km/h.
Explanation:
When two vectors are at right angles to each other, their resultant can be calculated by using the Pythagorean's theorem:
where
A is the magnitude of the first vector
B is the magnitude of the second vector
In this problem, we have two velocity vectors of magnitude
A = 100 km/h
B = 100 km/h
Substituting into the formula, we find their resultant:
