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 __________
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 )

A 2500 kg truck traveling at 80.0 km/h comes to stop in a time of 4.25 seconds. What is the force exerted on the truck?
Answer:
First there is a need to convert 80.0 km/h to m/s. It is equivalent to (200 / 9) m/s. Because the body stops after 4.25 seconds, its acceleration is -(200/9/4.25) m/s^2. The needed force to stop the 2500 kg truck is equal to the product of its mass and its acceleration.
Solving for the net force to stop the 2500 kg truck
Force = mass * acceleration
Force = 2500 kg * -(200/9/4.25) m/s^2
Force = −13072 N or about −13.07 kN
The force exerted on the truck is −13072 N or about −13.07 kN
In the image below, a worker is pushing a crate with a mass of 25 kg up a ramp at a constant rate. Ignoring friction, how much force must the worker apply so that the crate continues to move at the same speed? (Recall that g =

A. 35.3N
B. 83.8N
C. 50.2N
D. 16.2N
The image is missing, so i have attached it.
Answer:
B. 83.8N
Explanation:
The mass of the worker is 25 kg
From the image, the angle of the ramp is 20°
To find the force that the worker must apply to make the crate continue to move at the same speed, we will use the formula;
F = mg sin θ
F = 25 × 9.8 × sin 20
F ≈ 83.8 N

A constant current source supplies a electric current of 200 mA to a load of 2kΩ. When the load changed to 50Ω, the load current will be
8A
9mA
700mA
12A
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

Planet RMM-1 has a mass of 28,500 kg and the star it revolves around has
a mass of 2.20 x 10^8 kg. If the star emits a gravitational force of 39 N how
far away are the two objects from each other?
Gravitational force = G · (mass₁) · (mass₂) / (distance)
(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)
G = 6.67 x 10⁻¹¹ n-m² / kg² (the "gravitational constant")
Distance² = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)
Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)
Distance² = (418.209 N-m²) / (39N)
Distance² = 10.72 m²
Distance = 3.275 meters
An absurd scenario, but that's by golly what the math says with the numbers provided. I guess it's a teeny tiny planet orbiting 3.275 meters outside a teeny tiny black hole.

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.
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]
An ant is crawling on the sidewalk. At one moment, it is moving south a distance of 5.0 mm. It then turns southwest and crawls 4.0 mm. What is the magnitude of the ant’s displacement?
A) 8.3mm
B) 8.3cm
C) 8.3m
D) 8.3km
The correct answer is (A) 8.3mm.
The total displacement will be the vector sum of the two displacements given in the question.
let the displacement to the south represent vector A = 5mm in magnitude directed toward south.
let the displacement to the south-west represent vector B = 4mm in magnitude directed toward south-west.
The angle between vector A and vector B is 45°, the angle between south and south-west.
SO the resultant
R = vectro A + vector B
[tex]R=\sqrt{A^{2}+B^{2}+2ABcos(45) } \\\\R=\sqrt{25+16+40*\frac{1}{\sqrt{2} } } \\\\R=8.3mm[/tex]
The ant's displacement is 8.3 mm in magnitude.

Answer:
λ = 6 10⁻⁷ m, color orange
Explanation:
This problem is about the interference phenomenon, constructive interference occurs when the path difference is equal to an integer number of wavelengths
d sim θ = m λ
Let's use trigonometry, remembering that the angles for these experiments are very small.
Sin θ = y / L
tan θ = [tex]\frac{sin \theta}{cos \theta}[/tex] = sin θ
sin θ = y / L
we substitute
[tex]d \ \frac{y}{L} = m \lambda[/tex]
A) Donut length is requested

Objects A and B both have mass 2 kg. Object A has temperature 20°C and Object B has temperature 40°C. The specific heat of Object A is larger than that of Object B. The two objects are isolated from the environment and are brought into thermal contact with each other and allowed to come to thermal equilibrium. Is the final temperature of both objects greater than, less than or equal to 30°C? Briefly explain your reasoning.
Answer:
Equal to 30°C.
Explanation:
The final temperature of both objects are equal to 30°C because of the conduction heat from one object to another. Both objects have same mass of 2 kg and both were isolated from the external environment so conduction of heat occurs from the more hotter body to the less hotter body until the temperature of both objects are equal to each other.
The final temperature of both objects is less than 30° C
What is the specific heat of an Object?
The specific heat of an object is the minimum required quantity of heat needed to raise the temperature of 1 gram of the object(substance) by 1° C.
From the parameters given:
The mass of both Object A and B = 2kgThe temperature of Object A = 20° CThe temperature of Object B = 40° CUsing the Calorimetry principle, we need to understand that the heat lost by an object at a high temperature is proportionally equal to that heat gained by the object at a low temperature.
i.e.
[tex]\mathbf{Q_{lost}= Q_{gain}}[/tex]
[tex]\mathbf{ms_B \Big[40^0 \ C - \theta_o\Big]= ms_A \Big [ \theta_o - 20^0 \ C \Big]}[/tex]
Given that:
The specific heat of object A is larger than that of object B i.e. [tex]\mathbf{S_A> S_B}[/tex]Then, let us consider a scenario where [tex]\mathbf{S_A = 1.5S_B}[/tex]
Thus;
[tex]\mathbf{S_B \Big[40^0 \ C - \theta_o\Big]= 1.5S_B \Big [ \theta_o - 20^0 \ C \Big]}[/tex]
[tex]\mathbf{40^0 \ C - \theta_o= 1.5 \theta_o - 20^0 \ C}[/tex]
[tex]\mathbf{ 2.5\theta_o= 70^0 \ C}[/tex]
[tex]\mathbf{ \theta_o= \dfrac{70^0 \ C}{2.5}}[/tex]
[tex]\mathbf{ \theta_o=28 ^0 C}[/tex]
Therefore, we can conclude that since the specific heat of object A is larger than that of object B i.e. [tex]\mathbf{S_A> S_B}[/tex], then the final temperature [tex]\mathbf{ \theta_o<30 ^0 C}[/tex]

When a man is walking exhibit which type of equilibrium?
Answer:
Dynamic equilibrium
Explanation:
This is because dynamic equilibrium is when the body is set on motion at constant velocity. When humans are walking, when achieve unstable equilibrium that is not static or dynamic on the first foot and a non equilibrium when the other foot is involved. In human movement,it is at constant velocity and the Total number of forces acting is zero. This type of equilibrium always return to it's initial point after disturbances since humans did not continually walk all the time .
