Answer:

Earplugs

Explanation:

The objects that absorb the most sound waves are usually soft and flexible or porous. So, the object that satisfies the first two characteristics is Earplugs. It means that the answer is Earplugs.

Sound travels at approximately 343 meters (or 1,125 feet) per second in dry air at room temperature.

To determine how far away lightning is when thunder sounds 10 seconds after the lightning flash, we can use the speed of sound.

Distance = Speed × Time

Distance = 343 m/s × 10 s

Distance = 3,430 meters

Therefore, if thunder sounds 10 seconds after the lightning flash, the lightning is approximately 3,430 meters (or 3.43 kilometers) away.

Answer:

please ask this question separately

Explanation:

The formula for angular velocity as a function of time when it rises linearly can be used to address this issue:

ωz(t) = ωz,0 + αz t

If t is time, z,0 is the angular acceleration at rest, and z is the starting angular velocity.

Applying the information provided, we have:

ωz,0 = -6.00 rad/s (initial angular velocity)

z (6.0 s) = +4.0 rad/s (final angular velocity)

t = 6.00 s (time elapsed) (time elapsed)

The angular acceleration z is what we're looking for.

Using the formula's supplied values as substitutes, we obtain:

-6.00 rad/s + z = +4.00 rad/s (6.00 s)

When we simplify and find z, we obtain:

Z = (5.00 rad/s - 6.0 rad/s)

/6.00 s = 1.67 rad/s^2

As a result, the wheel's angular acceleration is 1.67 rad/s2.

The barriers to success for an Electric Automated Bike could include technological limitations, high costs, limited infrastructure, regulatory challenges, and consumer acceptance.

The success of an Electric Automated Bike could face several barriers.

Firstly, technological limitations could impact the performance and reliability of the bike's electric and automated systems. Issues such as battery range, charging infrastructure, and the efficiency of automated features may need to be addressed for widespread adoption.

Secondly, high costs can hinder the market penetration of electric automated bikes. The advanced technology, including electric motors, sensors, and automated systems, may contribute to higher prices, making them less affordable for the average consumer.

Limited infrastructure is another barrier. Electric automated bikes may require dedicated charging stations or infrastructure to support their operation, which may not be widely available or accessible in certain areas.

Regulatory challenges may also arise, as there may be a need for specific regulations and standards to govern the operation and safety of electric automated bikes. Ensuring compliance with existing laws or advocating for new regulations can be a complex process.

Finally, consumer acceptance and behavior play a crucial role. The market may require time to adapt to new technologies and embrace the concept of automated biking.

Consumer concerns about safety, reliability, and convenience need to be addressed to build trust and encourage adoption.

Overcoming these barriers requires a collaborative effort between technology developers, policymakers, infrastructure providers, and consumer awareness campaigns to address the challenges and create an environment conducive to the success of electric automated bikes.

In this given circuit, there are two resistors, R2 and R3 connected in series with a battery of 12 V as shown below;\(\Delta V = V = 12 V\)Let us first find the total resistance of the circuit.

Using the formula, resistances in series add up to give the total resistance of the circuit\(R_T = R_2 + R_3 = 8\ \Omega + 12\ \Omega = 20\ \Omega\)

Using Ohm's Law; the current through the circuit can be calculated as follows;

\(I_T = \frac{V}{R_T} = \frac{12\ V}{20\ \Omega} = 0.6\ A\)

Thus, the current through each of the resistors, R2 and R3 is the same and it is equal to the total current of the circuit;\(I_1 = I_2 = 0.6\ A\)

The potential difference across each of the two resistors, R2 and R3 is different because of the difference in resistance. Using Ohm's Law, the potential difference across each resistor can be calculated as follows;

\(\Delta V_2 = V_{R_2} = I_2 \cdot R_2 = 0.6\ A \cdot 8\ \Omega = 4.8\ V\)

\(\Delta V_3 = V_{R_3} = I_2 \cdot R_3 = 0.6\ A \cdot 12\ \Omega = 7.2\ V\)

Thus, the potential difference across resistor R2 is 4.8 V and across resistor R3 is 7.2 V.

Assuming the squirrel is jumping off the ground, here's what we know but don't really know...

v₀ = 4.0 at 50.0°

So that's not really the velocity we are looking for. We are dealing with a max height problem, which is a y-dimension thing. Therefore, we need the squirrel's upward velocity, which is NOT 4.0 m/s. We find it in the following way:

\(v_{0y}=4.0sin(50.0)\) which gives us that the upward velocity is

v₀ = 3.1 m/s

Moving on here's what we also know:

a = -9.8 m/s/s and

v = 0

Remember that at the very top of the parabolic path, the final velocity is 0. In order to find the max height of the squirrel, we need to know how long it took him to get there. We are using 2 of our 3 one-dimensional equations in this problem. To find time:

v = v₀ + at and filling in:

0 = 3.1 - 9.8t and

-3.1 = -9.8t so

t = .32 seconds.

Now that we know how long it took him to get to the max height, we use that in our next one-dimensional equation:

Δx = \(v_0t+\frac{1}{2}at^2\) and filling in:

Δx = \(3.1(.32)+\frac{1}{2}(-9.8)(.32)^2\) and using the rules for adding and subtracting sig fig's correctly, we can begin to simplify this:

Δx = .99 - .50 so

Δx = .49 meters

The answer is E. One-ninth as bright as star B if two star are of equal luminosity.

The apparent brightness of a star depends on its distance from the observer. According to the inverse square law, the apparent brightness of a star decreases as the square of the distance from the observer increases. In this case, star A is three times farther away from the observer than star B. Therefore, the apparent brightness of star A will be nine times less than that of star B.

Since the two stars are of equal luminosity, we can conclude that star A appears one-ninth as bright as star B. This is because the apparent brightness of a star is proportional to its luminosity divided by the square of the distance from the observer. Since the two stars have the same luminosity, the ratio of their apparent brightness is equal to the inverse square of the ratio of their distances from the observer.

We want to see if the Trust SSC can archive a higher maximum speed.

Remember the second Newton's law:

Force = mass*acceleration.

And acceleration is the rate of change of the velocity.

Assuming the mass of the Trust SSC does not change, increasing the force would mean that we increase the acceleration, and thus, larger velocities can be reached.

Now there are some problems.

How we do increase the force?.

It is hard to ve precise, mostly because we don't really know how the system works, we just got some given random data that we can't use without context.

Another thing we need to remember, this velocity is measured in only one mile. So because we have a fixed distance to measure it, we only can get larger velocities by increasing the acceleration.

And to increase the acceleration we can increase the force, as discussed, or, decrease the mass.

How to decrease the mass? Using lighter materials.

Now let's see an example on how decreasing the mass would affect the acceleration.

Then an aproximate force is given by:

F = 10,700kg*20.8 m/s^2 = 222,560 N

Now, if we decrease the mass a little bit, for example to 10,000kg, and we do not change the force, the new acceleration will be given by:

10,000kg*a = 222,560 N

a = (222,560 N)/(10,000kg) = 22.3 m/s^2

So decreasing the mass a little, increases the acceleration, which would make a larger maximum velocity.

Concluding, there are two ways of increasing the maximum velocity:

Increasing the force.
