Answers
Answer:
700ma
Explanation:
all u do is have to add them up.
Ohm's law allows us to calculate the result for the value of the current when we change the resistance of the circuit:
The current is: i = 8 A
Ohm's law establishes that voltage is proportional to current and we call the constant of proportionality resistance in a circuit.
V = i R
Where V is the voltage, i the current and R the resistance of the circuit.
They indicate that the source supplies a current of i = 200 mA = 0.200 A at a load of R = 2 kΩ = 2 10³ Ω
Let's find the source voltage.
V = 0.200 2 10³
v = 400 V
Now with this voltage let's find the current for the new load of R = 50 Ω
i = V / R
i = 400/50
i = 8 A
In conclusion using Ohm's law we can calculate the result for the value of the current when we change the resistance of the circuit is:
The current is: i = 8 A

Explanation:
|F_1on3| = |F_2on3|
k×q1×q3/x^2 = k×q2×q3/(d-x)^2
q1/x^2 = q2/(d-x)^2
(d-x)^2/x^2 = q2/q1
(d-x)/x = sqrt(q2/q1)
(2 - x)/x = sqrt(4×q/q)
(2 - x)/x = 2
2 - x = 2x
2 = 3x
x = 2/3
x= 0.667 cm

Explanation:
a mass of 0.8kg at the end of a rope 0.5m long is whirled round ina horizontal circle at an angular speed of 10 rads^-1. what is it's angular momentum?
Answers
Answer:
L = 2 J.s
Explanation:
The angular momentum of an object travelling in a horizontal circle is given by the following formula:
[tex]L = mvr[/tex]
where,
L = Angular momentum = ?
m = mass = 0.8 kg
v = linear speed = rω
r = radius of circular path = length of rope = 0.5 m
ω = Angular Speed = 10 rad/s
therefore,
[tex]L = mr^2\omega\\L = (0.8\ kg)(0.5\ m)^2(10\ rad/s)\\[/tex]
L = 2 J.s
The magnetic field strength in an experiment is 5.0 x 10–4 Newtons per Amp meter (or 5.0 x 10–4 N A–1m–1), where the unit of force is the Newton (N = kg m s–2) and the unit of current is the Ampere (A = C s–1). A Coulomb, C, is a unit of charge. The electric field strength in another experiment is 1.8 x 104 N C–1. From these parameters, both the magnetic displacement and the electric displacement were each measured to be 6.0 cm. Calculate the velocity of the particles.
Answers
Answer:
The velocity of the particles is "0.36×10⁸ m/s".
Explanation:
The given values are:
Magnetic field strength,
B = 5.0×10⁻⁴ N/Amp
In another experiment,
F = 1.8×10⁴
By considering the Lorentz force, the velocity will be:
⇒ [tex]qE=qvB[/tex]
then,
⇒ [tex]v=\frac{F}{B}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{1.8\times 10^4}{5.0\times 10^{-4}}[/tex]
⇒ [tex]=0.36\times 10^8 \ m/s[/tex]
Imagine a negative test charge sitting at the coordinate origin (0,0). Two bunches of positive charges are located on the x-axis and the y-axis, respectively, so that the vectors of the respective electric forces, which the test charge experiences, point from the origin at points (1,0) and (0,1), respectively. The total force vector, which the test charge experiences, points from the origin at the point __________
Answers
Answer:
the total force vector, on test charge is points from origin to point C( 1, 1 )
Explanation:
Given the data in the question, as illustrated in the image below;
from the Image, OA = 1, OB = AC = 1
so using Pythagoras theorem
a² = b² + c²
a = √( b² + c² )
so
OC = √( OB² + AC² )
we substitute
OC = √( OA² + AC² )
OC = √( 1² + 1² )
OC = √( 1 + 1 )
OC = √2
Coordinate of C( 1, 1 )
Hence, the total force vector, on test charge is points from origin to point C( 1, 1 )

We are given:
Mass of the Crate(m) = 71 kg
Applied force(F) = 577 N
Resolving the applied force:
To solve this problem, we will first make a free-body diagram (attached)
The Applied force has been resolved into 2 components denoted by a thinner line and 'g' is the acceleration due to gravity
We found the values by using basic trigonometry
Finding the Normal Force:
Normal force is equal and opposite to the net force applied on the ground. So, we will subtract the vertical component of the applied force from the weight of the crate.
Normal force = mg - F*Sin(27°)
Normal force = [(71)*(9.8)] - [ (577)(0.454) ] [g = 9.8 m/s²]
Normal Force = 433.84 N

A voltage is applied to a resistor,
which creates a 1.50 A current. If
you double the resistance, keeping
the voltage the same, what will the
new current be?
(Unit = A)
Answers
Answer:
Explanation:
By Ohms Law, Voltage = Current * Resistance
Keeping the voltage the same and doubling the resistance, the current will be halved.
So the new current = 1.5/2 = 0.75A
By using Ohms law, the current will be 0.75A.
What is Ohm's law?Ohm's law states that the current flowing through a resistance is proportional to potential difference across the resistance under constant temperature and pressure conditions. Ohm's law can be expressed as:
V =IR
Here, I = 1.50 AR = R Ωso, V = 1.50 R Now Voltage is same but resistance is doubled so new resistance is
Now, put the values of given data in ohms law formula:
2RI = 1.50 R/ 2R = 0.75A
Hence current is 0.75A
