Answer:
[tex]\boxed {\boxed {\sf 6 \ meters}}[/tex]
Explanation:
Work is the product of force and distance.
[tex]W=F*d[/tex]
We know that 96 Joules of work were done and a 16 Newton force was applied to the object.
W= 96 J F= 16 NSubstitute the values into the formula.
[tex]96 \ J= 16 \ N * d[/tex]
First, let's convert the units. This will make cancelling units easier later in the problem. 1 Joule (J) is equal to 1 Newton meter (N*m), so the work of 96 Joules equals 96 Newton meters.
[tex]96 \ N*m= 16 \ N * d[/tex]
Now, solve for distance by isolating the variable, d. It is being multiplied by 16 Newtons and the inverse of multiplication is division. Divide both sides of the equation by 16 N.
[tex]\frac {96 \ N*m}{16 \ N}= \frac{16 \ N *d}{16 \ N}[/tex]
[tex]\frac {96 \ N*m}{16 \ N}=d[/tex]
The units of Newtons cancel.
[tex]\frac {96}{16} \ m = d[/tex]
[tex]6 \ m = d[/tex]
The object moved a distance of 6 meters.

Dos cargas puntuales q1 = 6 x 10-6 C y q2 = 8 x 10-6 C están separadas 5 cm y ubicadas en el vacío. Calcule el valor de la fuerza entre las cargas.
Answer:
El valor de la fuerza entre las cargas es 172.8 N.
Explanation:
La fuerza electromagnética o electrostática es la interacción que se da entre cuerpos que poseen carga eléctrica.
La ley de Coulomb se emplea para calcular la fuerza eléctrica que actúa entre dos cargas en reposo y habla sobre la influencia que tienen las cargas y la distancia sobre la fuerza de atracción o repulsión de un cuerpo cargado eléctricamente. Esta ley indica que la magnitud de cada una de las fuerzas eléctricas con que interactúan dos cargas puntuales en reposo es directamente proporcional al producto de la magnitud de ambas cargas e inversamente proporcional al cuadrado de la distancia que las separa. La fuerza es de repulsión si las cargas son de igual signo, y de atracción si son de signo contrario.
La ley de Coulomb se representa matemáticamente mediante:
[tex]F=k*\frac{q1*q2}{r^{2} }[/tex]
donde:
F = fuerza eléctrica de atracción o repulsión en Newtons (N). k = es la constante de Coulomb o constante eléctrica de proporcionalidad. q1, q2 = valor de las cargas eléctricas medidas en Coulomb (C). r = distancia que separa a las cargas y que es medida en metros (m).En este caso:
k= 9*10⁹ [tex]\frac{N*m^{2} }{C^{2} }[/tex] Valor de la constante en el vacío. q1= 6*10⁻⁶ Cq2= 8*10⁻⁶ Cr= 5 cm= 0.05 mReemplazando:
[tex]F=9*10^{9} \frac{N*m^{2} }{C^{2} }*\frac{6*10^{-6}C *8*10^{-6}C}{(0.05 m)^{2} }[/tex]
Resolviendo se obtiene:
F= 172.8 N
El valor de la fuerza entre las cargas es 172.8 N.

If a train starts from rest and after 0.5 hours travels at a speed of 75 km/hr, what is its
acceleration?
Answer:
150 km/hr²
Explanation:
The data for the motion of the train includes;
The train starts from rest, therefore, the initial velocity of the train, u = 0 km/hr
The speed of the train after 0.5 hours, v = 75 km/hr
The change in time during the motion of the train, Δt = 0.5 hours
The acceleration, 'a', is the rate of change of velocity with time;
[tex]a = \dfrac{\Delta v}{\Delta t} = \dfrac{v - u}{\Delta t}[/tex]
Therefore, we have;
a = (75 km/hr - 0 km/hr)/(0.5 hr) = 150 km/hr²
a = 150 km/hr² = 150 km/hr² × 1,000 m/km × hr²/(3,600 s)² = 5/432 m/s²
The acceleration of the train, a = 150 km/hr² = 5/432 m/s².

A flashlight bulb is connected to two dry cells with an equivalent voltage of 4.50 V. If the bulb draws a current of 12.0 mA (1000mA = 1A), its resistance is (2 points) a 540. Ohms b 375 Ohms c 266 Ohms d 2.66 Ohms e 145 Ohms
Answer:
b. 375 Ohms
Explanation:
Given the following data;
Voltage = 4.5 V
Current = 12 mA
To find the resistance;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.Conversion:
1000 mA = 1 A
12 mA = 12/1000 = 0.012 A
[tex] R = \frac {V}{I} [/tex]
Substituting into the formula, we have;
[tex] R = \frac {4.5}{0.012} [/tex]
Resistance, R = 375 ohms

Two people push on the same door from opposite sides as shown. A man pushes on a door from the left. A woman pushes on the door from the right. They will only see the door move when
Answer:
The door will move when the forces exerted by each individual becomes unbalanced.
Explanation:
The Door will only move when the forces exerted by each of the individual is unbalanced i.e. when the Torque is unbalanced
This is because there will only be a reaction or movement of an object when the applied force > resistant force acting on the object.
example : An object at rest will only move when the applied force is greater than the frictional forces acting on the object at rest.
A leftward force of 7N is applied to a box while the force of friction is 3N. The weight of the box is 4N as is the normal force. Determine the net force, and its direction acting on the box. (Hint: draw a free body diagram to help you figure it out)
Answer:
0N
Explanation:
When you draw a free body diagram, You have a 7N arrow pointing left, and a 3N arrow pointing right. When you subtract the two, you still have a force of 4N on the left. However, seeing as how gravity is in play at a force of 4N, the two forces cancel out and you get 0N.
A charged particle is placed in an external magnetic field and it is moving in a circular path of radius 26m.The magnetic force acting on the particle is 16N.What is the kinetic energy of the particle
Answer:
208 Joules
Explanation:
The radius of the circular path the charge moves, r = 26 m
The magnetic force acting on the charge particle, F = 16 N
Centripetal force, [tex]F_c[/tex] = m·v²/r
Kinetic energy, K.E. = (1/2)·m·v²
Where;
m = The mass of the charged particle
v = The velocity of the charged particle
r = The radius of the path of the charged particle
Whereby the magnetic force acting on the charge particle = The centripetal force, we have;
F = [tex]F_c[/tex] = m·v²/r = 16 N
(1/2) × r × [tex]F_c[/tex] = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.
∴ (1/2) × r × [tex]F_c[/tex] = (1/2) × 26 m × 16 N = = (1/2)·m·v² = K.E.
∴ 208 Joules = K.E.
The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

devices to carry out specific tasks.
TRUE
FALSE
Answer:
True.
Explanation:
An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.
Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.
This electrical network which is usually a closed loop comprises of a device that provides the energy (voltage) to drive electrons or electric current; the device is referred to as a source such as a generator or battery.
Similarly, an integrated circuit (IC) also referred to as microchip can be defined as a semiconductor-based electronic component that comprises of many other tiny electronic components such as capacitors, resistors, transistors, and inductors.
Generally, integrated circuits (ICs) are used in virtually all modern electronic devices to carry out specific tasks or functions such as amplification, timer, oscillation, computer memory, microprocessor, etc.
An electron is moving at 7.4x105 m/s perpendicular to a magnetic field. It experiences a force of 2.0x10–13 N. What is the magnetic field strength?
Answer:
1.69 T
Explanation:
Applying,
F = BvqsinФ.................. Equation 1
Where F = Force, B = magnetic field, v = velocity, q = charge on an electron, Ф = angle between the electron and the field.
make B the subject of the equation,
B = F/(vqsinФ)............. Equation 2
From the question,
Given: F = 2.0×10⁻¹³ N, v = 7.4×10⁵ m/s, Ф = 90°
Constant: q = 1.60×10⁻¹⁹ C
Substitute into equation 2
B = 2.0×10⁻¹³/(7.4×10⁵×1.60×10⁻¹⁹×sin90°)
B = 0.169×10
B = 1.69 T

PLEASE HELP ILL MARK BRAINLIEST!!! A ball is initially thrown downwards with an initial speed of 20 m/s from the top of a 300 m tall building. The ball has a constant downward acceleration of 10 m/s ^ 2 a). What is the velocity of the ball immediately before it hits the ground at the base of the building?
Using the 3rd equation of motion:
= v² - u² = 2gs ------ [g = Acceleration due to gravity]
= v² - 20² = 2 × 10 × 300
= v² - 400 = 6000
= v² = 6000 - 400
= v = √5600
= v = 74.83 m/s

do transistors amplfy a.c or d.c
Explanation:
thet amplify DC, because of the voltage ( small current input signal)
Answer:
Yes,by using direct coupling(transistors) amplifier we will amplify low frequency (DC) signals. A transistor is certainly capable of taking a small-current input signal and controlling a high-current output at the same voltage, thereby amplifying the power of the input signal whether it's AC or DC.
