Answer:
A
The current through the solution is
B
The current is moving from B to A
Explanation:
From the question we are told that
The number of that move from A to B is
The time taken to move from A to B
Since the value of 1 charge is
The quantity of charge Q that flow from A to B is mathematically given as
The number of that move from A to B is
Since time taken to move from A to B is equal to time taken to move from B to A
The quantity of charge Q that flow from B to A is mathematically given as
The total quantity of charge is
The current flowing through the solution is
The flow is from B to A cause current flow from the positive terminal to negative terminal
Answer:
Explanation:
The intensity of a sound wave is given by
where
P is the power of the wave at the source
A is the area over which the sound wave propagates
In this problem, we have
P = 70.0 W is the power
We want to know the intensity at a distance of r = 25.0 m from the orchestra, so since the sound waves propagates radially, we must consider a spherical surface of radius r, so the area is
Therefore, the intensity of the wave is
Answer:
x = 727.5 km
Explanation:
With the conditions given using trigonometry, we can find the tangent
tan θ = CO / CA
With CO the opposite leg and CE is the adjacent leg which is the distance from the Tierral to Sun
D =150 10⁶ km (1000m / 1 km)
D = 150 10⁹ m.
We must take the given angle to radians.
1º = 3600 arc s
π rad = 180º
θ = 1 arc s (1º / 3600 s arc) (pi rad / 180º) =
θ = 4.85 10⁻⁶ rad
That angle is extremely small, so we can approximate the tangent to the angle
θ = x / D
x = θ D
x = 4.85 10-6 150 109
x = 727.5 103 m
x = 727.5 km
Answer:
Protons, Neutrons, and electrons
Explanation:
Protons, electrons and neutrons are subatomic particles
Protons is positively charged particle yan
The electrons a negatively cacricated particle
Neutrons are particles that have no charge
Answer: If you let a helium balloon go, and if, as it rises, it stays at a constant temperature, the volume of the balloon will. The magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same total volume as the object.
