A ball rolls from x = -5 m to x = 0 m in 1 second. What was its average velocity?(Units = m/s)
Don't forget: velocities and displacements to the right are +, to the left are -.

Answers

Answer:

\(5\; {\rm m\cdot s^{-1}}\).

Explanation:

Displacement is the change in position. In this example, the position of this ball changed from the initial value of \(x_{0} = (-5)\; {\rm m}\) to the final value \(x_{1} = 0\; {\rm m}\). Subtract the initial position from the final position to find the change in position:

\(\begin{aligned} & (\text{Displacement}) \\ =\; & (\text{Change in Position}) \\ =\; & (\text{Final Position}) - (\text{Initial Position}) \\ =\; & 0\; {\rm m} - (-5)\; {\rm m} \\ =\; & 5\; {\rm m} \end{aligned}\).

Velocity is the rate of change in position. To find average velocity (average rate of change in position), divide the total change in position (displacement) by the time required for the change:

\(\begin{aligned} & (\text{Average Velocity}) \\ =\; & \frac{(\text{Total Change in Position})}{(\text{Time Required})} \\ =\; & \frac{(\text{Displacement})}{(\text{Time Required})}\\ =\; & \frac{5\; {\rm m}}{1\; {\rm s}} \\ =\; & 5\; {\rm m\cdot s^{-1}} \end{aligned}\).

Therefore, the average velocity will be \(5\; {\rm m\cdot s^{-1}}\).

Fighter jets on aircraft carriers are accelerated down a 270 foot "runway" in two seconds when they are taking off. A fully loaded, combat ready F-15 has a maximum take-off weight of 62,000 pounds. To ensure the pilot can reach sufficient velocity within 2 seconds a pneumatic cannon propels the plane down the runway. If this same cannon was used to launch your Toyota Corolla (mass is 2646lbs), how fast in miles per hour would you be going after reaching the end of the runway?

Answers

The speed of the  Toyota Corolla would have  been 143.9 mph.

What is the acceleration of the F-15?

The acceleration of the F-15 can be calculated as follows:

Acceleration = Velocity Change / Time = (Take-off Speed) / Time

where;

Take-off Speed = √(2dg /t²)

Take-off Speed = √(2 x  (270 ft)  x 32.2 ft/s² / (2 s)²)

T  = √(17496) = 131.6 ft/s

Acceleration = Velocity Change / Time

= (131.6 ft/s) / (2 s) = 65.8 ft/s²

We can use the same acceleration to launch the Toyota Corolla, and calculate its final velocity:

Final Velocity = Initial Velocity + Acceleration x Time

where;

Initial Velocity = 0 (because the car is not moving initially), Time = 2 s

Final Velocity = 0 + (65.8 ft/s²) * (2 s) = 131.6 ft/s

Finally, we can convert the velocity from feet per second to miles per hour:

Velocity (mph) = Velocity (ft/s) x (1 hour/3600 s) x (5280 ft/mile)

= 131.6 ft/s x  (1 hour/3600 s)  x (5280 ft/mile)

= 143.9 mph

Explanation:

From the question,

F = ma................... Equation 1

Where F = force exerted on the ball, m = mass of the ball, a = acceleration

But,

v² = u²+2as.............. Equation 2

Where v = final velocity, u = initial velocity, s = distance.

Given: v = 12 m/s, u = 0 m/s (from rest), s = 5.0 m

Substitute into equation 2 and solve for a

12² = 0²+2×a×5

144 = 10a

10a = 144

a = 144/10

a = 14.4 m/s²

Also Given: m = 5.2 kg,

Substitute into equation 1

F = 5.2×14.4

F = 74.88 N

Hence the force exerted on the ball is 74.88 N

what is v(b), the electric potential at the inner surface of the conducting shell? define the potential to be zero at infinity.

Answers

In order to determine the electric potential at the inner surface of a conducting shell, we need to know the charge distribution on the shell and the potential at a reference point.

Assuming the conducting shell is a spherical shell with uniform charge density, we can use the following steps to determine the electric potential at the inner surface:

Define a reference point as the point at infinity where the potential is zero. Since the conducting shell is an equipotential surface, the potential is constant at all points on the inner surface. Use the definition of electric potential to calculate the potential difference between the reference point and a point on the inner surface of the shell.

The potential at the inner surface of the shell is the sum of the potential difference and the potential at the reference point. Therefore, the electric potential at the inner surface of the conducting shell, V(B), is given by:

V(B) = V(infinity) + ΔV

where V(infinity) is the potential at infinity, which is defined to be zero, and ΔV is the potential difference between infinity and the inner surface of the shell.

Assuming the conducting shell has a total charge Q and a radius R, the potential difference can be calculated as:

ΔV = kQ/R

where k is the Coulomb constant. Therefore, the electric potential at the inner surface of the conducting shell is:

V(B) = 0 + kQ/R

which indicates that the potential at the inner surface of the shell is proportional to the total charge on the shell and inversely proportional to the radius of the shell.

pi t - 2 pi/3 = pi/3
pi t - 2 pi/3 = 5pi/3
Solving the first equation:
pi t = pi/3 + 2 pi/3

241 W/(m · K)

253 W/(m · K)

232 W/(m · K)

Answers

The thermal conductivity of the metal is approximately B, 241 W/(m · K).

How to determine thermal conductivity?

To find the thermal conductivity (k) of the metal, use the formula:

Q = k × A × (ΔT/Δx) × t

Where:

Q = Heat conducted by the rod (in Joules)

A = Cross-sectional area of the rod (in square meters)

ΔT = Temperature difference across the rod (in Kelvin)

Δx = Length of the rod (in meters)

t = Time (in seconds)

Given:

Q = 8.5 g of ice melted = 8.5 × Lf (latent heat of fusion of ice)

Lf = 3.34 × 10⁵ J/kg

Δx = 60 cm = 0.6 m

A = 1.25 cm² = 1.25 × 10⁻⁴ m²

t = 10 min = 600 seconds

ΔT = (100°C - 0°C) = 100 K

Substituting the given values into the formula:

8.5 × Lf = k × (1.25 × 10⁻⁴) × (100 K / 0.6 m) × 600 s

Simplifying the equation:

k = (8.5 × Lf) / [(1.25 × 10⁻⁴) × (100 K / 0.6 m) × 600 s]

Calculating the value:

k = (8.5 × 3.34 × 10⁵) / [(1.25 × 10⁻⁴) × (100 / 0.6) × 600]

k ≈ 241 W/(m · K)

g What inductance is needed in series with a 4.7-μF capacitor so the circuit will oscillate at a frequency of 10 kHz?

Answers

To determine the required inductance, we can use the formula for the resonant frequency of an LC circuit:
f = 1 / (2π√(LC))
where f is the desired frequency (10 kHz), C is the capacitance (4.7 μF), and L is the unknown inductance. Solving for L, we get:
L = 1 / (4π^2f^2C)
Plugging in the given values, we get:
L = 1 / (4π^2 × 10,000^2 × 4.7 × 10^-6) ≈ 7.23 mH

Therefore, an inductance of approximately 7.23 mH is needed in series with the 4.7-μF capacitor for the circuit to oscillate at a frequency of 10 kHz.
To find the inductance needed in series with a 4.7-μF capacitor for the circuit to oscillate at a frequency of 10 kHz, you can use the formula for resonant frequency in an LC circuit:
f = 1 / (2 * π * √(L * C))
where f is the frequency, L is the inductance, and C is the capacitance. Rearrange the formula to solve for L:
L = 1 / (4 * π^2 * f^2 * C)

Substitute the given values:
L = 1 / (4 * π^2 * (10,000 Hz)^2 * 4.7 * 10^-6 F)

Answers

While standing in a low tunnel, you raise your arms and push against the ceiling with a force of 100 N and mass is 70 kg.

Hence, the correct option is C.

When you push against the ceiling with a force of 100 N, the ceiling exerts an equal and opposite force on you (Newton's third law). This means that the ceiling exerts a force of 100 N on you downwards.

The force that the ceiling exerts on you is also known as the normal force (N) because it is perpendicular to the surface (ceiling) on which you are applying the force.

To calculate the force that the floor exerts on you, we need to consider the forces acting on you in the vertical direction. There are two forces your weight (due to gravity) and the normal force from the floor. When these forces are in equilibrium, you are not accelerating in the vertical direction, i.e. you are at rest.

The weight of you is given by

W = mg

Where W is the weight, m is the mass, and g is the acceleration due to gravity (9.8 m/\(s^{2}\)).

W = (70 kg)(9.8 m/\(s^{2}\)) = 686 N

W = 686 N

Since you are at rest, the forces in the vertical direction must balance each other out. Therefore, the normal force from the floor must be equal to your weight.

Normal force from floor = W = 686 N

Therefore, the force that the floor exerts on you is 686 N.

Hence, the correct option is C.

Capacitance is a property of a capacitor and represents its ability to store electrical charge. It is denoted by the symbol C and is measured in farads (F).

The capacitance of a capacitor is determined by its physical characteristics, such as the size, shape, and materials used. It can be calculated using the equation:

C = Q / V

C =  capacitance in farads,

Q = charge stored in the capacitor in coulombs,

V = voltage across the capacitor in volts.

In practical terms, capacitance describes the amount of charge that a capacitor can store per unit voltage. A capacitor with a higher capacitance can store more charge for a given voltage, while a capacitor with a lower capacitance can store less charge.

The farad (F) is a relatively large unit of capacitance, and in many cases, capacitors are commonly measured in smaller units such as microfarads (μF), nanofarads (nF), or picofarads (pF), which are equivalent to 10⁻⁶ F, 10⁻⁹ F, and 10⁻¹² F, respectively.

Thus, a capacitor's capacitance reflects its capacity to hold an electrical charge. It is measured in farads (F) and has the sign C.

A recent study revealed that one in five teenagers has at least some hearing loss. The rate of hearing loss among young people has grown significantly since about 1990. Now, experts are urging kids to turn down the volume on their digital music players. These experts suggest that listening to loud music through earbuds may be responsible for the increase.For the study, researchers compared data from two nationwide health surveys of hearing loss in 12- to 19-year-olds. The first study was done between 1988 and 1994. The second was done between 2005 and 2006. In the first study, about 15 percent of teens were found to have at least some hearing loss. In the more recent study, 19.5 percent of teens had at least some hearing loss. This means that about 6.5 million young people have at least some difficulty hearing.Most of the hearing loss in the teens was "slight." Researchers defined "slight" as an inability to hear at 16 to 24 decibels. A teen with slight hearing loss might not be able to hear sounds such as leaves rustling or someone whispering. Dr. Gary Curhan was the study's senior author. According to Curhan, people with slight hearing loss can hear vowel sounds clearly. However, they might miss sounds from some consonants, such as t, k, and s. Experts warn that this minor loss of hearing is sufficient to cause problems in school. It also sets the stage for hearing aids later in life."Although speech will be detectable, it might not be fully intelligible," Curhan said. Researchers lack final evidence that listening to iPods and other music devices is to blame for hearing loss in teens. However, researchers did note a significant increase in high-frequency hearing loss. This particular type of hearing loss, researchers said, indicates that noise may be to blame. Researchers cited a 2010 Australian study. The study linked the use of personal listening devices with a 70 percent increased risk of hearing loss in young people"I think the evidence is out there that prolonged exposure to loud noise is likely to be harmful to hearing, but that doesn't mean kids can't listen to MP3 players," Curhan said. "Our hope is we can encourage people to be careful."Loud music isn't anything new, of course. Each recent generation of teens has found a new technology to blast music. Teens listened to bulky headphones in the 1960s and used the handheld Sony Walkmans in the 1980s. Today's teens, however, spend more time than ever listening to music. In fact, according to audiologist Brian Fligor, young people spend more than twice as much time listening to music than previous generations.One of Fligor's patients is 17-year-old Matthew Brady of Foxborough, Massachusetts. Matthew has a mild hearing loss. He has trouble hearing his friends in the school cafeteria. He has admitted to occasionally faking comprehension. Matthew used to listen to an iPod turned up too loud and for too long. Fligor believes this caused Matthew's muffled hearing.Matthew used to crank up the volume on his favoritesDaughtry, Bon Jovi, and U2while walking on a treadmill. He did this at least four days a week for 30-minute stretches at a time. One day last summer, he got off the treadmill and couldn't hear anything with his left ear. His hearing gradually returned, but it was never the same.Matthew's fondness for listening to loud music in not uncommon. During a study of college students, Fligor found that more than half of those tested listened to music at 85 decibels or louder. That's about as loud as a hair dryer or a vacuum cleaner. According to Fligor, regular listening at those levels can turn microscopic hair cells in the inner ear into scar tissue. Fligor believes that some people, such as Matthew, may be more likely to experience damage than others.These days, Matthew still listens to his digital music player. But now he listens at lower volumes."Do not [blast] your iPod," Matthew cautions other teens. "It's only going to hurt your hearing. I learned this the hard way."The Associated Press contributed to this story.The news article says all of the following except __________.A.Listening to loud music can turn microscopic hair cells in the inner ear into scar tissue.B.Most young people listen to music that is twice as loud as a hair dryer or vacuum cleaner.C.Experts believe that about 6.5 million young people have at least some difficulty hearing.D.Hearing loss was discovered in 19.5 percent of teenagers tested between 2005 and 2006.
