Captain Young lost a total of 1 hour and 20 minutes from the original flight plan by avoiding the storm. He made two detours, each lasting for one hour, and an additional 20 minutes for the third turn.

Captain Young initially travels east at a speed of 720 km/h. When he encounters the electrical storm, he makes a 20-degree turn north to avoid it. He continues in this new direction for one hour, which accounts for the first detour.

After one hour, he makes a second turn back toward his original flight path. Eighty minutes after this second turn, he makes a third turn to return to the original course.

Adding up the time durations, we have:

- First detour: 1 hour

- Second detour: 80 minutes (1 hour and 20 minutes)

- Third turn: 20 minutes

The total time lost from the original flight plan is the sum of these durations, which is 1 hour + 1 hour and 20 minutes + 20 minutes = 2 hours and 40 minutes. Therefore, Captain Young lost a total of 1 hour and 20 minutes from the original flight plan by avoiding the storm.

The speed of the wave remains unchanged.

The speed of a wave is determined by the product of its wavelength and frequency. This can be represented by the formula: speed = wavelength x frequency

If the frequency of a wave is doubled while the wavelength remains the same, then the product of the wavelength and frequency will remain constant. This means that the speed of the wave will also remain constant.

To understand this, let's consider an example:

Suppose the original frequency of a wave is f, and its wavelength is λ. Then, the speed of the wave is given by:

speed = λ x f

Now, if the frequency is doubled, the new frequency becomes 2f. The wavelength remains the same at λ. So, the new speed of the wave can be calculated as: new speed = λ x 2f = 2(λ x f) = 2 x speed

As we can see, the new speed is twice the original speed, which contradicts our assumption that the speed remains constant. Therefore, the speed of the wave remains unchanged when the frequency is doubled while the wavelength remains the same.

The minimum force needed to make the crate start tipping is 294 N.

To find the minimum force required, we need to determine the point at which the torque created by the applied force overcomes the torque created by the crate's weight.

At the tipping point, the applied force acts at a distance equal to the height of the crate (1.6 m), and the weight of the crate acts at a distance of half the crate's depth (0.4 m).
The formula for torque is: torque = force × distance
At the tipping point, the torques balance each other, so:
applied_force × height = weight × (depth/2)
Let's calculate the crate's weight: weight = mass × gravitational_acceleration
weight = 60 kg × 9.8 m/s² = 588 N
Now, we can find the applied force:
applied_force × 1.6 m = 588 N × 0.4 m
applied_force = (588 N × 0.4 m) / 1.6 m
applied_force = 294 N

Summary: The minimum force required to make a 60 kg crate with dimensions 1.6 m x 0.8 m x 0.8 m start tipping is 294 N.

Answer:

There are \(9.537\times 10^{-23}\) kilograms of radioactive material after 300 seconds.

Explanation:

From Physics we know that radioactive materials decay at exponential rate, whose differential equation is:

\(\frac{dm}{dt} = -\lambda\cdot m\) (1)

Where:

\(\frac{dm}{dt}\) - Rate of change of the mass of the radioactive material, measured in kilograms per second.

\(m\) - Current mass of the radioactive material, measured in kilograms.

\(\lambda\) - Decay constant, measured in \(\frac{1}{s}\).

The solution of the differential equation is:

\(m(t) = m_{o}\cdot e^{-\lambda\cdot t}\) (2)

Where:

\(m_{o}\) - Initial mass of the radioactive material, measured in kilograms.

\(t\) - Time, measured in seconds.

If we know that \(m_{o} = 20\,kg\), \(\lambda = 0.179\,\frac{1}{s}\) and \(t = 300\,s\), then the initial mass of the radioactive material is:

\(m(t) = (20\,kg)\cdot e^{-\left(0.179\,\frac{1}{s} \right)\cdot (300\,s)}\)

\(m(t) \approx 9.537\times 10^{-23}\,kg\)

There are \(9.537\times 10^{-23}\) kilograms of radioactive material after 300 seconds.

The frequency of a photon with an energy of 1.33 × 10^−21 joules can be calculated using the equation E=hf, where E is the energy of the photon, h is Planck's constant (6.626 × 10^-34 joule-seconds), and f is the frequency of the photon. Rearranging this equation, we get f=E/h.

Substituting the given values, we get f= (1.33 × 10^-21)/ (6.626 × 10^-34) = 2.006 × 10^12 Hz. Therefore, the frequency of the photon is 2.006 × 10^12 Hz.

In summary, the frequency of a photon with an energy of 1.33 × 10^-21 joules is 2.006 × 10^12 Hz. It is important to note that the energy and frequency of a photon are directly proportional, meaning that as the energy increases, the frequency also increases. This relationship is described by the equation E=hf, where h is Planck's constant.

The velocity of the astronout, weighted of 60kg, is 0.5m/s to the left when a wrench he throwed moves to the right.

To solve this problem we will use the Conservation of Momentum theory. Conservation of momentum stated that the total momentum in a system remains constant without any external forces.

From the case, we know that:

m1 = 60kg

m2 = 3kg

v1 = v2 = 0m/s

v2' = 10m/s to the right

v1' ?

Using the conservation of momentum concept, we know that the astronaut's velocity is:

ΔP = ΔP'

m1.v1 + m2.v2 = m1.v1' + m2.v2'

60(0) + 3(0) = 60.v1' + 3(10)

0 = 60.v1' + 30

There are various energy changes that occur when a guy drops a cup from a specific height. The cup's elevation above the ground gives it potential energy.

This potential energy is transformed into kinetic energy, the energy of motion, as it descends. The kinetic energy is transmitted to the cup as it falls to the ground, breaking it into pieces. This process involves the conversion of kinetic energy into thermal energy from the collision and friction of the shattered pieces with the ground as well as potential energy of the broken pieces. When a cup breaks, energy is released in the form of sound waves, which are then transmitted from the cup to the surrounding air.

Instruments with a minimum value of least count provide a more precise measurement because the least count represents the smallest increment that can be measured by the instrument.

The least count is typically defined by the instrument's design and its scale or resolution.

When you use an instrument with a small least count, it allows you to make more accurate and precise measurements. For example, let's consider a ruler with a least count of 1 millimeter (mm).

If you want to measure the length of an object and the ruler's markings allow you to read it to the nearest millimeter, you can confidently say that the object's length lies within that millimeter range.

However, if you were using a ruler with a least count of 1 centimeter (cm), you would only be able to estimate the length of the object to the nearest centimeter.

This larger least count introduces more uncertainty into your measurement, as the actual length of the object could be anywhere within that centimeter range.

Instruments with smaller least counts provide greater precision because they allow for more accurate measurements and a smaller margin of error.

By having a finer scale or resolution, these instruments enable you to distinguish smaller increments and make more precise readings. This precision is especially important in scientific, engineering, and other technical fields where accurate measurements are crucial for experimentation, analysis, and manufacturing processes.
