10C of charge flow through a resistor in 4 seconds. What is the current?
Answer:
Very simple. The charge Q= 20 C. the formula for Q= I* t. now I= Q/t = 20/1s = 20 Amps.
Explanation:
The current given that the charge is 10C and the time is 4 seconds is gotten as Current = 2.5 Amps
Given Data
Charge = 10 Columbs
Time = 4 seconds
Current = ?
Current, charge and time RelationshipElectrical current is defined by how much electric charge has been transferred per second, giving the following relationship:
Charge = Current*Time
Rearranging this we get:
Current = Charge/Time
The symbol for charge is Q , it is measured in coulombs (C).
The symbol for current is I , it is measured in amperes (A).
The symbol for time is T, it is measured in seconds (s).
Substituting our given Data into the expression we have
Current = 10/4
Current = 2.5 Amps

Calculate the charge on two identical spheres that are similarly charged if they are separated by 20cm and the electrostatic force between them is 0.006 N.
Answer:
[tex]Q = 21.09 \times 10^{-8} C[/tex]
Explanation:
We know from theory that the magnitude of the force between two charges is measured by the expression
[tex]F=\frac1{4\pi\epsilon} \frac{Qq}{r^2}[/tex]
We know that two spheres have the same charge, and let's assume they're in a vacuum, so [tex]\epsilon = \epsilon_0 =8.85\times10^{-12} C^2/Nm^2[/tex]
At this point we can solve for Q
[tex]Q^2 = 4\pi\epsilon F r^2 = 4\pi \times (8.85 \times 10^-12)\times (6\times 10^-3) \times (2 \times 10^-1)^2 = 444.624 \times 10^{-17} = 4446.24\times 10^-16 C^2 \rightarrow Q = 21.09 \times 10^{-8} C[/tex]

The strength of the electric field 0. 5 m from a 6 µC charge is _______ N/C. (Use k = 8. 99 × 109 N•meters squared per Coulomb squared and round answer to the nearest whole number. ) 215760 539400 697976 512356.
The strength of the electric field at a distance of 0.5 m from a 6 μC punctual charge is 143,840 N/C.
We want to calculate the strength of the electric field 0.5 m (r) from a 6 μC charge (Q).
What is the electric field?The electric field (E) is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
We can calculate the electric field at some distance from a punctual charge using the following formula.
E = (k × Q) / r²
E = [(8.99 × 10⁹ N.m².C²) × (4 × 10⁻⁶ C)] / (0.5 m)² ≈ 143,840 N/C

k is the Coulomb's law constant.The strength of the electric field at a distance of 0.5 m from a 6 μC punctual charge is 143,840 N/C.

What acceleration occurs if the friction force in #4 is now 4N?
The acceleration of the 20 N force is 6.67 m/s^2. The acceleration of the 4N force is 1.33 m/s^2.
What is force?We define the force that acts on a body as that which is able to cause an acceleration or that which is able to change the direction of an object. Recall that from the Newton first law, an object would continue in its state of rest or uniform motion unless the object is acted upon by an external force.
Now the frictional force is the force that tends to resist the motion of two surfaces that are in contact. Owing to the fact that it is a resistive force its direction is always opposite the force that seeks to move the object forward.
Now;
F = ma
a = F/m
a = 20 N/3Kg
a = 6.67 m/s^2
If the force is 4N;
a = F/m
a = 4N/3Kg
a = 1.33 m/s^2

The reading on a metronome indicates the number of oscillations per minute. What are the frequency and period of the metronome's vibration when the metronome is set at 180?
Answer:
Period: 1/3= 0.33 seconds.
The frequency and period of the metronome's vibration when the metronome is set at 180 is 3Hz and 0.33 s.
What is the frequency?Frequency is the number of oscillations per second.
The time period is the reciprocal of the frequency.
Given is the metronome set at 180.
The reading of metronome = frequency in seconds = 180 / 60 = 3 Hz
The time period of the metronome's vibration T = 1/3 = 0.33 seconds.
Thus, the frequency and the time period is 3Hz and 0.33 s.

1. A student pushes horizontally on a book with a force of 2 N, which causes the book to slide at a constant velocity. What is the force of friction on the book?
Answer:
The horizontal forces are equal in size and opposite in direction. They are balanced, so the horizontal resultant force is zero. This means that there is no horizontal acceleration just a horizontal constant speed. If a submarine is not moving horizontally, then there are no horizontal forces.

25 n object requires a 5. 0 n to start moving over a horizontal surface. What is the coefficient of static friction?.
Answer:
μ=1/5=0.2
Explanation:
using the formula
Fs=Fn*μ
Where
Fs is the static force
Fn = Normal force
μ= coefficient
so if Fn=25n
and it requires 5 n to start moving, means the max Fs is 5n
5=25μ
μ=5/25
μ=1/5=0.2
