Answer:
Its a MAGNETIC FIELD that can let a magnet attracts more iron dusts
Answer:
The answer to the question is
The magnitude of the displacement needed to get the ball into the hole in just one putt is 1.746m in the direction of 23.41° north east
Explanation:
With trigonometric relation and the attached diagram we have
From the diagram the location of the hole is 3.32m- (1.57 cos45 +0.78co45)m North and
1.57sin 45 – 0.78 sin 45 meters west
1.658m north and
0.55m east
Thus the direction of the hole is 26.41 degrees
North east
The magbitude of the displacement is displacement is gotten from the relation diplacement of x and y =√(x²+y²)
∠26.41°
Answer:
The capacitor will charge
Explanation:
When the capacitor is connected to the circuit containing the battery and the resistor, charges (electrons) will start flowing through the circuit, pushed by the electromotive force produced by the battery. In particular:
- electrons will flow from the negative terminal of the battery to one plate of the capacitor
- electrons will flow from the other plate of the capacitor to the positive terminal fo the battery
(It's important to keep in mind that the electrons never cross the gap between the plates of the capacitor.)
Therefore, negative charge will accumulate on one plate of the capacitor and positive charge will accumulate on the other plate: and so, there will be an increasing potential difference across the plates of the capacitor. Due to this increasing potential difference, it will become more and more difficult for the battery to "push" electrons on the negative plate (and to remove them from the other plates), so the current in the circuit will keep decreasing.
The process stops when the potential difference across the gap of the capacitor is equal to the e.m.f. of the battery: at this point, there is no more current in the circuit, and the capacitor is said to be fully charged.
Answer:
a. 77.9 nT
Explanation:
Given;
average value of the electromagnetic wave, E = 0.724 W/m^2
The average value of a Poynting vector is given by;
Therefore, the maximum value of the magnetic field in the wave is 77.9 nT.
