what was the initial velocityof the t-shirt as it left the cannon?

According to the question, If you drop a grand piano down a mine shaft, you would get a flat note.

This humorous response plays on the double meaning of the word "note." In the context of music, a "flat note" refers to a musical tone that is lower in pitch than the corresponding natural note. However, in this context, the phrase "flat note" is used to suggest that the grand piano would be damaged or destroyed upon impact with the ground at the bottom of the mine shaft. It is a lighthearted play on words rather than a literal answer.

 P /K = 1,997 10⁻³⁶  s⁻¹

Explanation:

For this exercise let's start by finding the radiation emitted from the accelerator

       \(\frac{dE}{dt}\) = \(\frac{q^{2} a^{2} }{6\pi \epsilon_{o} c^{2} }\)

the radius of the orbit is the radius of the accelerator a = r = 0.530 m

let's calculate

       \frac{dE}{dt} = [(1.6 10⁻¹⁹)² 0.530²] / [6π 8.85 10⁻¹² (3 108)³]

      P= \frac{dE}{dt}= 1.597 10⁻⁵⁴ W

Now let's reduce the kinetic energy to SI units

       K = 5.0 10⁶ eV (1.6 10⁻¹⁹ J / 1 eV) = 8.0 10⁻¹⁹ J

Explanation:

For a conductor with radius r, resistivity p, length L and resistance R;  \([(R\pi r^2)/L]/m\) is an equivalent expression to the ratio \(p/m\).

Resistance refers to the property of a material or an object to resist the flow of electrical current through it. The given information about a conductor indicates that it has a radius r, a length L, and a resistance R.

The resistance R of the conductor can be expressed as:

\(R = (p*L)/A\)

where p is the resistivity of the conductor, L is the length of the conductor, and A is the cross-sectional area of the conductor given by:

\(A = \pi *r^2\)

Therefore,

\(R = (pL)/(\pi r^2)\)

Solving for p, we get:

\(p = (R\pi r^2)/L\)

We can now express the ratio p/m as:

\(p/m = [(R\pi r^2)/L]/m\)

where m is the mass of the conductor.

Since we do not have information about the mass of the conductor, we cannot simplify this expression any further.

Hence, \([(R\pi r^2)/L]/m\) is an equivalent expression to the ratio p/m.

Anti-predator adaptation.

Explanation:

Their habitat is the forest and woodland. Their way of life fits into the anti-predator adaptation but I'm not 100% sure that I'm correct.

The main answer to the problem is:T = m(g + a)where T is the tension force, m is the mass of the object, g is the acceleration due to gravity (9.8 m/s2) and a is the upward acceleration of the object (1.50 m/s2).

The tension force in a rope or cable is the force that is transmitted through the rope when a force is applied at one end of the rope. In this problem, the gymnast is climbing up the rope with an upward acceleration of magnitude 1.50 m/s2. We can use the equation T = m(g + a) to calculate the tension force in the rope

.To use the equation, we need to know the mass of the gymnast. Let's assume that the mass of the gymnast is 60 kg. We also know that the acceleration due to gravity is 9.8 m/s2.Substituting the values into the equation:T = m(g + a)T = 60 kg (9.8 m/s2 + 1.50 m/s2)T = 60 kg (11.3 m/s2)T = 678 NTherefore, the tension force in the rope is 678 N.

The total distance travelled during the vehicle's journey as found from the speed-time graph is 6.125 m

V = d / t

V = ( u + v ) / 2

V = Average Speed

d = Distance

t = Time

u = Initial velocity

v = Final velocity

During the first 0.5 s, u = 0 and v = 1 m / s.

d = ( 0 + 1 ) * 0.5 / 2

d = 0.25 m

During the next 0.5 s, u and v are equal meaning constant velocity ( V = 1 m / s ).

d = 1 * 0.5

d = 0.5 m

During the next 1 s, u = 1 m / s and v = 1.5 m / s.

d = ( 1 + 1.5 ) * 1 / 2

d = 1.25 m

During the next 2.5 s, u and v are equal meaning constant velocity ( V = 1.5 m / s ).

d = 1.5 * 2.5

d = 3.75 m

During the next 0.5 s, u = 1.5 m / s and v = 0.

Answer:

  r2 = 1 m

therefore the electron that comes with velocity does not reach the origin, it stops when it reaches the position of the electron at x = 1m

Explanation:

For this exercise we must use conservation of energy

the electric potential energy is

          U = \(k \frac{q_1q_2}{r_{12}}\)

for the proton at x = -1 m

          U₁ =\(- k \frac{e^2 }{r+1}\)

for the electron at x = 1 m

          U₂ = \(k \frac{e^2 }{r-1}\)

starting point.

        Em₀ = K + U₁ + U₂

        Em₀ = \(\frac{1}{2} m v^2 - k \frac{e^2}{r+1} + k \frac{e^2}{r-1}\)

final point

         Em_f = \(k e^2 ( -\frac{1}{r_2 +1} + \frac{1}{r_2 -1})\)

energy is conserved

        Em₀ = Em_f

        \frac{1}{2} m v^2 - k \frac{e^2}{r+1} + k \frac{e^2}{r-1} = k e^2 (- \frac{1}{r_2 +1} + \frac{1}{r_2 -1})              

        \frac{1}{2} m v^2 - k \frac{e^2}{r+1} + k \frac{e^2}{r-1} = k e²(  \(\frac{2}{(r_2+1)(r_2-1)}\) )

we substitute the values

½ 9.1 10⁻³¹ 450 + 9 10⁹ (1.6 10⁻¹⁹)² [ \(- \frac{1}{20+1} + \frac{1}{20-1}\) ) = 9 109 (1.6 10-19) ²( \(\frac{2}{r_2^2 -1}\) )

          2.0475 10⁻²⁸ + 2.304 10⁻³⁷ (5.0125 10⁻³) = 4.608 10⁻³⁷ ( \(\frac{1}{r_2^2 -1}\) )

          2.0475 10⁻²⁸ + 1.1549 10⁻³⁹ = 4.608 10⁻³⁷     \(\frac{1}{r_2^2 -1}\)

          \(\frac{2.0475 \ 10^{-28} }{1.1549 \ 10^{-37} } = \frac{1}{r_2^2 -1}\)

          r₂² -1 = (4.443 10⁸)⁻¹

          r2 = \(\sqrt{1 + 2.25 10^{-9}}\)

The length of the rope required for the flagpole is approximately 16.8 meters.

Let 'l' be the length of the rope required for the flagpole, 'h' be the height of the flagpole, and 'θ' be the angle between the flagpole and the ground. It is given that the shadow cast by the flagpole is 14.6 meters long. Hence, using trigonometry, we get:tan θ = h/ltan θ = (14.6/l)l = 14.6/tan θHere, θ = 55° (approx). Hence,l = 14.6/tan 55°= 16.8 meters (approx).Therefore, the length of the rope required for the flagpole is approximately 16.8 meters. The angle that the sun makes with the ground is 35 degrees since it is given that the pole casts a shadow 14.6 meters long.

Answer:

The height of the water column = 1.62405\(\overline{30}\) × 10⁻¹ m

Explanation:

The air cavity in the Coke bottle = 0.220 m deep

The fundamental (frequency) it plays when water is added to shorten the column and it is blown across the top, f = 528 Hz

The given speed of sound in air, v = 343 m/s

We note that the air cavity in the coke bottle is equivalent to a tube closed at one end

The fundamental frequency for a tube closed at one end, 'f', is given as follows;

f = v/(4·L) = v/λ

Where;

L = The height of the water column

λ = The wavelength of the wave

∴ 4·L = v/f = (343 m/s)/(528 Hz) = 0.6496\(\overline{21}\) m

∴ L = 0.6496\(\overline{21}\) m/4 = 0.162405\(\overline{30}\) m

Answer:

The answer is A) 247 J, which is the closest to the calculated value.

Explanation:

To calculate the work done on the bag, we need to use the formula:

work = force x distance x cos(theta)

where force is the weight of the bag (mg), distance is the length of the room, and theta is the angle between the force and the displacement (which is zero since the force and displacement are in the same direction).

First, let's calculate the force:

force = weight of the bag = mg = (6.00 kg) x (9.81 m/s^2) = 58.86 N

Next, let's calculate the distance:

distance = length of the room = 4.220 m

Now, we can calculate the work done:

work = (58.86 N) x (4.220 m) x cos(0) = 247.68 J

Answer:

When using the PASS technique with a fire extinguisher, it is important to ensure you stand far enough away from the flames in order to be safe. As a general rule, it is best to stand at least 8-10 feet away from the fire.

This is to ensure that you do not come too close to the heat or flames and to also ensure you are not in danger of being burned. Additionally, standing further away provides you with better access to the fire in terms of directing the extinguisher towards the source of the fire. When spraying the fire, make sure you keep the nozzle pointed towards the base of the fire.

This will ensure you are able to put the fire out quickly and effectively. Lastly, if the fire is too large or close, back away and wait for the fire department to arrive.
