When two pulses meet up with each other while moving through the same medium, they have a tendency to bounce off each other and return back to their origin?

When you drive along the right-rear side of another vehicle, you are in one of the driver's blind spots and in danger of a collision.

Driving is the controlled operation and movement of a vehicle, including cars, motorcycles, trucks, buses, and bicycles.

The most critical thing to do before you pass another vehicle is check to the right side.  It is also very important never to drive faster than the the speed limit, or at a speed that is unsafe for the current traffic,

weather or road condition in order to pass other vehicles. The law requires you to only pass other vehicles on the left (using the left lane). This is why you should check the right side.

Hence when you drive along the right-rear side of another vehicle, you are in one of the driver's blind spots and in danger of a collision.

Answer: The velocity of the wave is 20m/s

Explanation: The velocity of a wave can be obtained by the equation:

Velocity = wavelenght*frequency.

or v = λ*f

In this case, we know that: λ = 100 meters, f = 0.2Hz (where Hz means 1/s)

then, we have that the velocity of the wave is:

v = 100m*(0.2*1/s) = (100*0.2)m/s = 20m/s

The speed of a wave is mathematically given as

[tex]\lambda= 20m/s[/tex]

Question Parameters:

the speed of a wave with a frequency of 0.2 Hz

and a wavelength of 100 meters

Generally, the equation for the  Wave speed (m/s)  is mathematically given as

The phone has fallen approximately 36.621 meters after 2.7 seconds.

In order to determine how far the phone has fallen after 2.7 seconds, we can use the equation of motion: s = ut + (1/2)at², where s is the distance, u is the initial velocity, t is the time, and a is the acceleration. Since the phone is dropped from rest, its initial velocity is 0 m/s. Neglecting air resistance, the only force acting on the phone is gravity, which accelerates it at a rate of 9.8 m/s². Plugging in the values, we get:

s = (0)(2.7) + (1/2)(9.8)(2.7)²

s = 36.621 m

Therefore, the phone has fallen approximately 36.621 meters after 2.7 seconds.

The acceleration of a cheetah that can increase its speed from 0 to 70 mph in 2.2 seconds is 14.224 m/s² after converting the velocity into meters per second.

To calculate the acceleration of a cheetah that can go from 0 to 70 mph in 2.2 seconds, we first need to convert the speed from miles per hour (mph) to meters per second (m/s). The conversion factor is 1 mph = 0.44704 m/s. So, 70 mph is equivalent to 70 × 0.44704 m/s, which equals 31.2928 m/s. According to the formula for acceleration (a), which is the change in velocity (Δv) divided by the time (Δt), the cheetah's acceleration would be:

a = Δv / Δt = (31.2928 m/s - 0 m/s) / 2.2 s = 14.224 m/s²

Therefore, the cheetah's acceleration is 14.224 m/s².

There are the points which describe the non similarities between symbolic and analogical representation:

Answer:

Z: Gamma rays

X: Visible light

Explanation:

A close look at the diagram attach shows the core of the sun and then the external surface.

Gamma rays are intricately associated with the nuclear reactions that go on in the core of the sun that makes it to produce light. Hence Z must refer to gamma rays emitted in these nuclear processes at the core of the sun.

Visible light is given out by the sun and seen externally. Hence X is visible light.

The efficiency of the light bulb is 75%.

Calculating The Efficiency Of A Light Bulb.

To calculate the efficiency of the light bulb, you can use the following formula:

Efficiency (%) = (Useful Energy Output / Total Energy Input) * 100

In this case:

- Useful Energy Output is the light energy produced, which is 450 J.

- Total Energy Input is the electrical energy used, which is 600 J.

Efficiency (%) = (450 J / 600 J) * 100 = (3/4) * 100 = 75%

So the efficiency of the light bulb is 75%. This means that 75% of the electrical energy input is converted into useful light energy, while 25% is wasted as other forms of energy, such as heat.

Final answer:

Q represents the amount of heat energy required for phase change in the context of latent heat equations. It is calculated using mass and the substance-specific latent heat constants for fusion and vaporization.

Explanation:

In the context of the latent heat formulas, Q represents the heat required to change the phase of a substance. Specifically, for the latent heat of fusion, Q = mLf where Lf is the latent heat of fusion, the constant that denotes the amount of heat energy required to change 1 kilogram of the substance from a solid to a liquid without changing its temperature. For the latent heat of vaporization, Q = mLv where Lv is the latent heat of vaporization, indicating the amount of heat energy needed to change 1 kilogram of the substance from a liquid to a gas. The values of Lf and Lv are determined experimentally for different materials. For instance, for water, Lf is 334 kJ/kg, thus Q for turning 1 kilogram of ice at 0°C into water is Q = 3.34 × 105 J. The latent heat of vaporization for water is Lv = 2256 kJ/kg, meaning the energy required to vaporize mass m of water is Qv = mLv.

Explanation:

To determine the concentration of Pb2+ in the anode compartment, we can use the Nernst equation. By rearranging the Nernst equation and plugging in the given values, we can calculate the concentration of Pb2+ in the anode compartment.

To determine the concentration of Pb2+ in the anode compartment, we need to use the Nernst equation. The Nernst equation relates the cell potential to the concentration of ions in each compartment of the cell. It is given by: Ecell = E°cell - (0.0592/n) × log([Pb2+]/[Sn2+]), where Ecell is the cell potential, E°cell is the standard cell potential, [Pb2+] is the concentration of Pb2+ in the anode compartment, [Sn2+] is the concentration of Sn2+ in the cathode compartment, and n is the number of electrons transferred in the balanced redox reaction.

In this case, the cell potential is 0.24 V, [Sn2+] is 1.50 M, and n is 2 (since it is a Sn2+/Pb2+ redox reaction). Therefore, the equation becomes: 0.24 = E°cell - (0.0592/2) × log([Pb2+]/1.50). We can rearrange this equation to solve for [Pb2+]: [Pb2+] = (10^((E°cell - 0.24) × 2 / 0.0592)) × 1.50.

Hello!

I believe the answer is C) The Moon and Earth rotate at the same rate. The moon and the earth rotate at the same rate. Meaning that the moon orbits the earth in 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. So as a result, the moon does not seem to be spinning, but appears to observers from Earth to be keeping almost perfectly still.

I hope it helps!
