Answer: there is 0.02 sec between when the capacitor voltage maximizes and the inductor voltage maximizes
Explanation:
Given that time period T = 0.04 sec
Now as the voltage across inductor maximizes, voltage across the capacitor minimizes and vice - versa;
Now, between capacitor maximizing and Inductor maximizing, there is a time of T/2
i.e t = T/2
so from our question; Time period is 0.04sec
now
t = 0.04 / 2
t = 0.02 sec
Therefore there is 0.02 sec between when the capacitor voltage maximizes and the inductor voltage maximizes

A horizontal spring required a force of 1.0 N to compress it 0.1 m. How much work is required to stretch the spring 0.4 m?
Answer:
0.5JExplanation:
given data
Force applied F= 1N
extension e= 0.1m
let us find the spring constant first
applying
F=ke
k=F/e
k=1/0.1
k=10N/m
Step two:
Required is the work done
we know that the expression/formula for the work done by a spring is given as
Wd=1/2kx^2
x=0.4m
substitute
Wd= 1/2*10*0.4^2
Wd=0.5*10*0.16
Wd=0.5J

Explanation:
An object has an acceleration of 18 m/s/s. If the mass of this object were tripled (with no change in its net force), then its new acceleration would be
Answer: 6
If the mass of this object were tripled (with no change in its net force) =>Its acceleration will decrease by 3 times
=> the new acceleration would be: 18/3 = 6(m/s²)

A soccer ball is kicked from the ground with a velocity of 30m/s directed at an angle of 45 degrees with respect to horizontal. Resolve this velocity vector into horizontal and Vertical components
Answer:
Vertical = 21.2 m/s
Horizontal = 21.2 m/s
Explanation:
For the vertical component:
sin (45) = v/30
sin (45) x 30 = v
21.2 m/s = v
For the horizontal component:
cos (45) = h/30
cos (45) x 30 = h
21.2 m/s = h
A 60.0-cm, uniform, 5.00-kg shelf is supported horizontally by two vertical wires attached to a sloping ceiling. The front wire is inset by a distance of 20 cm. A very small 2.50-kg tool is placed on the shelf midway between the points where the wires are attached to it.
Required:
Find the tension in the back wire.
Image is missing, so i have attached it
Answer:
Tension in back wire = 24.5 N
Explanation:
let the tension in the back wire be Tₒ
let the tension in the front wire be T
Applying static equilibrium in the vertical direction, we have:
T + Tₒ = (5 × 9.8) + (2.5 × 9.8)
T + Tₒ = 73.5
Where Tₒ = (2.5 × 9.8) = 24.5 N
Thus, Tension in back wire = 24.5 N
The tension in the back wire equals 24.5 N.
We can arrive at this answer with the static equilibrium formula, for that, let's consider that the tension in the back wire is represented by the letter "t," while the tension in the front wire is represented by the letter "T."
Therefore, we can use the following formula:
[tex]t= W*g\\t= 2,5*9.8\\t= 24.5 N[/tex]
In this case, the letter "W" refers to the tool weight, while the letter "g" refers to gravity.

A car travels at a constant speed up a ramp making an angle of 28 degrees with the horizontal component of velocity is 40 kmh^-1, find the vertical and horizontal component of velocity.
Answer:
Vx = 35.31 [km/h]
Vy = 18.77 [km/h]
Explanation:
In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.
[tex]v_{x} = 40*cos(28)\\V_{x} = 35.31 [km/h][/tex]
In order to find the vertical component, we must use the sine function of the angle.
[tex]V_{y}=40*sin(28)\\V_{y} = 18.77 [km/h][/tex]

Calculate the total energy of 2.0 kg object moving horizontally at 10 m/s 50meters above the surface.
1080 J
2 00 J
1 00 J
10. J
Answer:
1080J
Explanation:
Given parameters:
Mass of object = 2kg
Velocity = 10m/s
Height = 50m
Unknown:
Total energy = ?
Solution:
The total energy of the moving object is obtainable by summing the kinetic and potential energy;
Total energy = P.E + K.E
P.E is the potential energy = mgh
K.E is the kinetic energy = [tex]\frac{1}{2}[/tex]mv²
Now insert the parameters and solve;
Total energy = mgh + [tex]\frac{1}{2}[/tex]mv²
m is the mass
g is the acceleration due to gravity
h is the height
v is the velocity
Total energy = (2 x 9.8 x 50) + ( [tex]\frac{1}{2}[/tex] x 2 x 10²)
Total energy = 980 + 100 = 1080J
When the force at the ends of a bar pushes rather than pulls, the bar experiences
Answer:
Compression
Explanation:
Force is defined as a push or pull on any object. Now, Force could either be in Compression or tension which are the push and pull that allow overhead bridges to remain erect after many years.
Now, Compression is a force that compresses objects together. Meanwhile, Tension is the opposite of compression and it is the force that pulls objects apart.

) A friend of yours complains that he often has lower back pain. One day while he picks up a package, you notice he bends at his hips rather than keeping his back straight and bending his knees. Assume he pivots at the hips so that his spine is horizontal. His back muscles then exert a force at 48 cm away from the hips at 13.5 degrees above the horizontal (directed slightly up and to the left in the picture shown). The weight of his upper body is 560 N, and his center of mass is 38 cm from the hips. Draw a force diagram of the spine. What total force is exerted by the back muscle when he picks up a 10 kg package at 82 cm from the hips? Extra credit: Find the force exerted by the hips on the spine/pelvis
Answer:
Explanation:
Please see the figure attached for free body diagram .
Taking torque about the hip joint ,
560 x 38 + 100 x 82 = F sin13.5 x 48
21280 + 8200 = 11.2 F
F = 2632.14 N .
Force exerted by the hip on the spine = 2632.14 N .

When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). The racquet exerts a force of 443 N on the ball for 4.30 ms, giving it a final velocity of 45.7 m/s. Using these data, find the mass of the ball.
Answer:
0.041kgExplanation:
Step one:
given data
initial velocity u= 0m/s
Force F= 443N
time t= 4.3 ms= 0.0043seconds
final velocity v= 45.7m/s
Step two:
Required
mass m
we know that the expression for impulse is given as
Ft=mv
make m subject of the formula
m=Ft/v
substitute we have
m=443*0.0043/45.7
m=1.90/45.7
m=0.04kg
The mass of the ball is 0.041kg
