The force F acting on a body varies with the displacement s from a point O as shown in the graph.
(a) Calculate the work done when the body is displaced
(i) from s=0 to s = 0.4 m
(ii) from s=0 to s =0.8 m
(b) If the mass of the body is 0.20 kg and its initial velocity is 2.00 m/s, find its velocity
(i) when s = 0.4 m
(ii) when s = 0.8 m
Answers
a.i) The work done when the body is displaced from s=0 to s = 0.4 m is 0.8 J.
(a.ii) The work done when the body is displaced from s=0 to s = 0.8 m is 1.2 J.
(b.i) The final velocity of the body when the displacement is 0.4 m is 3.46 m/s.
(b.ii) The final velocity of the body when the displacement is 0.8 m is 4 m/s.
What is work done?The work done on an object is the product of force and displacement of the object.
The work done between 0 to 0.4 m is determined from the area of the triangle formed.
W = ¹/₂(0.4 m - 0 m) x ( 4 N )
W = ¹/₂(0.4 m) x ( 4 N )
W = 0.8 J
The work done from s=0 to s =0.8 m,
W = ( Area of 0 to 0.4 m) + ( Area of 0.4 m to 0.8 m)
W = 0.8 J + ¹/₂(0.8 m - 0.4 m) x ( 2 N )
W = 0.8J + ¹/₂(0.4 m) x ( 2 N )
W = 0.8J + 0.4 J
W = 1.2 J
The final velocity of the body is calculated by applying work energy principle.
change in kinetic energy of the body = work done by the body
¹/₂m(v₂² - v₁²) = W
Where;
m is the mass of the bodyv₁ is the initial velocityv₂ is the final velocitywhen, s = 0.4 m, the final velocity is calculated as;
¹/₂m(v₂² - v₁²) = 0.8 J
¹/₂(0.2)(v₂² - 2²) = 0.8
0.1(v₂² - 2²) = 0.8
v₂² - 2² = 0.8 / 0.1
v₂² - 2² = 8
v₂² = 8 + 4
v₂² = 12
v₂ = √12
v₂ = 3.46 m/s
when s = 0.8 m, the final velocity is calculated as;
¹/₂(0.2)(v₂² - 2²) = 1.2 J
0.1(v₂² - 2²) = 1.2
v₂² - 2² = 1.2 / 0.1
v₂² - 2² = 12
v₂² = 12 + 4
v₂² = 16
v₂ = √16
v₂ = 4 m/s

Explanation:
A tabletop gamer has designed a game that requires three dice to be thrown onto a tray with a measurement grid. To add an extra degree of randomness, the coordinates of the center of mass of the three dice are used as well. The masses of the three dice are 11.10 g, 15.10 g, and 18.90 g, and their respective coordinates after one particular throw are (0.3150 m,−0.4990 m), (−0.4050 m,0.4850 m), and (−0.1150 m,−0.1850 m).
Requried:
What are the resulting coordinates of the center of mass of the dice, xcm and ycm?
Answers
Answer:
The resulting coordinate is \((x,y) = (-0.170 \ m , -0.038 \ m )\)
Explanation:
From the question we are told that
The mass of the first dice is \(m_1 = 11.10 \ g\)
The mass of the second dice is \(m_2 = 15.10 \ g\)
The mass of the third dice is \(m_3 = 18.90 \ g\)
The coordinate of the first dice is \((x_1, y_1) = (0.3150\ m , -0.4990 \ m )\)
The coordinate of the second dice is \((x_2,y_2) = (-0.4050 \ m , 0.4850 \ m )\)
The coordinate of the third dice is \((x_3 , y_3) = (-0.1150 \ m , -0.1850\ m )\)
Generally the resulting coordinate of the center of mass of the dice in the x-axis is mathematically evaluated as
\(x\ cm = \frac{m_1 * x_1 + m_2 * x_2 + m_3 * x_3}{m_1 + m_2 +m_3 }\)
i.e the summation of the moments about their x-axis divided by the magnitude of their masses
substituting values
\(x\ cm = \frac{11.0 * 0.3150 + 15.10 * (-0.4050) + 18.90 * (-0.1150)}{11.100 + 15.10 +18.90 }\)
\(x\ cm = -0.170 \ m\)
Generally the resulting coordinate of the center of mass of the dice in the y-axis is mathematically evaluated as
\(y\ cm = \frac{m_1 * y_1 + m_2 * y_2 + m_3 * y_3}{m_1 + m_2 +m_3 }\)
\(y\ cm = \frac{ 11.10 * (-0.4990) + (15.10) * (0.4850) + (18.90) * (-0.1850)}{ 11.10 + 15.10 +18.90 }\)
\(y\ cm = -0.038 \ m\)
Thus the resulting coordinate is \((x,y) = (-0.170 \ m , -0.038 \ m )\)

A transformer has a primary coil with 175 turns of wire and a secondary coil with 700 turns. An AC voltage source connected across the primary coil has a voltage given by the function
Δv = (200 V)sin(t).
What rms voltage (in V) is measured across the secondary coil?
Answers
The rms voltage measured across the secondary coil is 565.68 V.
What does rms value mean?The root mean square (RMS) value of an alternating current (AC) or voltage is the equivalent steady direct current (DC) value that produces the same heating effect or power dissipation in a resistor. In other words, it is the DC voltage or current that would produce the same amount of heat as the AC voltage or current over a given time period.
The rms voltage (V_rms) across the secondary coil can be calculated using the formula:
V_rms,secondary = (N_secondary/N_primary) * V_rms,primary
where N_secondary is the number of turns in the secondary coil, N_primary is the number of turns in the primary coil, and V_rms,primary is the rms voltage across the primary coil.
The rms voltage across the primary coil can be found from the given voltage function:
V_rms,primary = (1/√2) * V_peak,primary
where V_peak,primary = 200 V is the peak voltage across the primary coil.
Substituting the values, we get:
V_rms,primary = (1/√2) * 200 V = 141.42 V
Now, using the formula above, we can calculate the rms voltage across the secondary coil:
V_rms,secondary = (700/175) * 141.42 V = 565.68 V
Therefore, the rms voltage measured across the secondary coil is 565.68 V.

What is the shape of a line graph that shows the temperature change over time of the liquid before it starts to boil.
Answers
The shape of a line graph displaying temperature change over time before boiling is typically linear and increasing.
In a line graph showing the temperature change over time of a liquid before it starts to boil, the shape is generally linear and increasing.
This is because as heat is applied to the liquid, its temperature increases at a consistent rate.
During this phase, the heat energy is used to increase the kinetic energy of the molecules in the liquid, causing a rise in temperature.
Once the boiling point is reached, the graph may show a plateau, as the energy is then used to change the liquid's state rather than further increase the temperature.

What angle would you use for the greatest distance when the projectile leaves at zero height above ground g
Answers
Answer: 45 degree
Explanation:
Since Range = Ucosø × T
Where T = total time.
Range = distance covered
T = 2usinø/ 2g
If you substitute T into the range formula, you will get
R = (Ucosø×2Usinø) / 2g
But in trigonometry, 2sinøcosø = sin2ø
Substitute it into the formula
R = Usin2ø/ 2g
If ø = 45 degree
R = Usin(2 × 45)/2g
R = Usin90 / 2g
But sin 90 = 1
Therefore,
Range R = U/2g
Therefore, 45 degree angle would be use for the greatest distance when the projectile leaves at zero height above ground.
Answer:
∴ the angle for greatest distance is 90°, where Vy = 0
Explanation:
maximum height of a projected object is highest vertical position of the trajectory object which depends on the initial velocity
formula for maximum height
H= u² sin²θ/2g
if θ = 90°, then sin²90° = 1
∴ the angle for greatest distance is 90°, where Vy = 0
for horizontal distance,
the range of a projectile is the horizontal distance.
R = u² sin2θ/g
if θ = 45°, then 2θ = 90°
∴sin 90°= 1
Which describes the magnetic field that forms when a wire carries an electric current?
Answers
The magnetic field that forms when a wire carries an electric current is a circular field that is strongest at the ends of the wire and weakest in the middle.
What does a current-carrying wire's magnetic field look like?A current-carrying wire's magnetic field looks like a series of concentric circles that extend outward from the wire in both directions.
The magnitude of the magnetic field is greatest at the center of the wire and decreases as you move away from it.
The direction of the magnetic field is determined by the direction of the current flow: if the current is flowing clockwise around the wire, then the magnetic field will be pointing outward from the wire.
The magnetic field also has a north and south pole, so the direction of the field also depends on which direction around the wire the current is flowing.

Un levantador de pesas puede generar 3000 N de fuerza ¿Cuál es el peso máximo que puede levantar con una palanca que tiene un brazo de la fuerza de 2 m y un brazo de resistencia de 50 cm?
Answers
Responder: 12000N
Explicación: Usando la fórmula para encontrar la eficiencia de una máquina. Eficiencia = ventaja mecánica / relación de velocidad × 100%
Dado MA = Carga / Esfuerzo
Relación de velocidad = distancia recorrida por esfuerzo (brazo de fuerza) / distancia recorrida por carga (brazo de resistencia)
MA = Carga / 3000
VR = 2 / 0.5 VR = 4
Asumiendo que la eficiencia es 100% 100% = (Carga / 3000) / 4 × 100%
1 = (Carga / 3000) / 4
4 = Carga / 3000
Carga = 4 × 3000
Carga = 12000N
Esto significa que el peso máximo que se puede levantar es 12000N

two mass damper on a lagos tower consist of a 373mg concrete block.that complete one oscillation in.6.80 secs .the oscillation amplitude in a high wind is 110cm. determine the spring constant
Answers
If two mass dampers on a Lagos tower consist of a 373mg concrete block.that complete one oscillation in.6.80 secs. the oscillation amplitude in a high wind is 110cm. Then the spring constant of the mass-spring system is 6.90 N/m.
The spring constant is a measure of the stiffness of a spring, which describes how much force is required to stretch or compress the spring by a certain amount. It is typically measured in units of newtons per meter (N/m).
We can use the formula for the period of oscillation of a mass-spring system:
T = 2π√(m/k)
where T is the period of oscillation, m is the mass of the block, and k is the spring constant.
We can rearrange this formula to solve for k:
k = (4π²m) / T²
where we substitute the values given in the problem.
m = 373mg = 0.373g = 0.000373kg (convert milligrams to kilograms)
T = 6.80 s
π ≈ 3.14159
Plugging in these values, we get:
k = (4π² × 0.000373) / (6.80)²
≈ 6.90 N/m
Therefore, the spring constant of the mass-spring system is approximately 6.90 N/m.

Two objects are known to have the same momentum. Do these two objects necessarily have the same kinetic energy?
Answers
Answer:
No
Explanation:
Momentum is a measure of mass times velocity. But kinetic energy is one-half the mass times the square of the velocity, so it’s much more dependent on the velocity than on the mass. You could have two objects with the same momentum, one very massive but traveling slowly, and the other with only a little mass but traveling at a high velocity - and the latter one would have the higher kinetic energy.
Answer:
No
Explanation:
Kinetic energy equation
\(e = \frac{1}{2} m {v}^{2} \)
Momentum equation
\(p = mv\)
Therefore
\(e = pv\)
So, they should have same velocity and momentum
