4. If 1 car is going faster than another traveling in the same direction, can they have the same velocity? Why or why
not?
Help please 15 points ??? ASAP
Answer:
No, because objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. The average velocity of an object moving in a constant direction is calculated with the formula: velocity = distance/time.

Suppose we increase the temperature of the air through which a sound wave is traveling.
a. What effect does this have on the speed of the sound wave? Explain.
b. For a given frequency, what effect does increasing the temperature have on the wavelength of the sound wave? Explain.
a. When the temperature of the air increases, the speed of the sound wave also increases.
b. For a given frequency, increasing the temperature increases the wavelength of the sound wave.
a. The temperature of the medium and the speed of sound wave traveling within the medium is directly proportional. Hence as the air temperature increases, sound wave speed travelling through the air also increases. This happens because the air molecules gain more kinetic energy due to the higher temperature, which causes them to move faster and transfer energy more efficiently, thus increasing the speed at which the sound wave travels.
b. For a given frequency, increasing the temperature results in an increase in the wavelength of the sound wave. This is because the speed of the sound wave increases, as explained earlier. Since the speed of sound (v) is related to its frequency (f) and wavelength (λ) through the equation v = fλ, if the speed increases while the frequency remains constant, the wavelength must also increase to maintain the equation's balance.

How many gy of gamma-ray photons cause the same biological damage as 0.34 gy of alpha radiation?
Therefore, approximately 0.017 gy of gamma-ray photons would cause the same biological damage as 0.34 gy of alpha radiation.
To determine the number of gy (gray) of gamma-ray photons that would cause the same biological damage as 0.34 gy of alpha radiation, we need to understand the concept of relative biological effectiveness (RBE). RBE is a measure of the relative damage caused by different types of radiation.
In this case, we can use the RBE values for gamma-ray photons and alpha radiation to compare their biological effects. The RBE of gamma-ray photons is generally considered to be 1, meaning that 1 gy of gamma-ray photons has the same biological effect as 1 gy of X-rays or gamma rays.
On the other hand, the RBE of alpha radiation is much higher, typically around 20. This means that 1 gy of alpha radiation causes about 20 times more biological damage compared to gamma-ray photons.
To find the number of gy of gamma-ray photons that would cause the same biological damage as 0.34 gy of alpha radiation, we divide 0.34 gy by the RBE of alpha radiation (20).
0.34 gy / 20 = 0.017 gy
Therefore, approximately 0.017 gy of gamma-ray photons would cause the same biological damage as 0.34 gy of alpha radiation.

Capacitor electric field [8 pts.] A fully charged parallel-plate capacitor with a plate separation of 12.5 mm and a capacitance of 10 uF stores 8 m) of energy. Find the electric field strength inside the capacitor. (A) 42 V/m (B) 320 V/m (C) 1250 V/m (D) 2260 V/m (E) 3200 V/m << +8 (F) 4200 V/m
We know that the energy stored in a parallel-plate capacitor can be expressed as:$$E=\frac{1}{2}CV^2$$where E is the energy in joules (J), C is the capacitance in farads (F), and V is the voltage across the plates in volts (V).Now we can find the electric field inside the capacitor.
Let E be the electric field strength, d be the plate separation, and A be the area of each plate. The capacitance C can be expressed as:
\($$C=\frac{\epsilon_0A}{d}$$\)
where ε0 is the permittivity of free space, which is approximately equal to 8.85 x 10-12 F/m.
Therefore, we have:
\($$C=\frac{\epsilon_0A}{d}$$\)
Rearranging this equation gives:
\($$A=\frac{Cd}{\epsilon_0}$$$$A=\frac{(10×10^{-6})×(12.5×10^{-3})}{8.85×10^{-12}}=1.418×10^{-2}m^2$$\)
Now we can find the electric field inside the capacitor. The potential difference V between the plates can be found using the energy stored in the capacitor. Therefore, we have:
\($$V=\sqrt{\frac{2E}{C}}$$$$V=\sqrt{\frac{2×(8×10^{-3})}{10×10^{-6}}}=\sqrt{16}=4V$$\)
The electric field strength E inside the capacitor can be expressed as:\($$E=\frac{V}{d}=\frac{4}{12.5×10^{-3}}=320V/m$$\)
Therefore, the answer is (B) 320 V/m.

A tennis ball "A" is released from rest down a 10.0 m long inclined ramp with a uniform acceleration of 5.0 m/s2 . Another tennis ball "B" is initially located at the same height as ball "A" right above the lower edge of the ramp. Ball "B" is thrown upward with some initial speed at the same instant as the release of ball "A". A) What was the initial velocity of ball "B" so that "A" and "B" reach the bottom of the ramp at the same time?
Answer:
4.8 m/s
Explanation:
For tennis ball "A", we are told that;
Initial velocity; u = 0 m/s
Distance; h = 10 m
Acceleration; a = 5 m/s²
Thus, using Newton's equation of motion, we can find time(t).
h = ut + ½at²
10 = 0 + ½(5)t²
10 = ½(5t²)
t² = 2 × 10/5
t² = 4
t = √4
t = 2 seconds
Now, this time would be the same for ball B since we are told that they reach the bottom at the same time.
Now, since ball B is thrown upwards, it means it is thrown against gravity. Thus;
h = -ut + ½gt²
10 = -2u + ½(9.8)(2²)
Where u is initial velocity of Ball B.
Thus;
10 = -2u + 19.6
2u = 19.6 - 10
2u = 9.6
u = 9.6/2
u = 4.8 m/s
Explain the term the refractive index of glass is 1.5
Answer:
Refractive index of a glass is 1.5 means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.
Explanation:
Refractive index is defined as a ratio between the speed of light in a vacuum and the speed of light in a medium. Since the refractive index is a ratio between two speeds it is a dimensionless number. For the glass, having a refractive index of 1.5, means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.
for gas with a constant mass, in the ideal gas equation is constant. what can you say about the relationship between pressure, volume, and temperature?
The relationship between pressure, volume, and temperature is given by the ideal gas equation states that the pressure, volume, and temperature of a gas with a constant mass are inversely proportional to one another.
This means that as one increases, the other two must decrease. For example, when the temperature rises, the pressure and volume must decrease, and vice-versa. This is because a higher temperature increases the kinetic energy of the molecules, causing them to move faster and take up more space, while a decrease in temperature slows down the molecules, resulting in a decrease in volume and an increase in pressure.
Therefore, when one of these three variables is changed, the other two must adjust accordingly in order to maintain the equation.

It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously
The sound intensity level of 100 physics professors talking simultaneously is equal to 72 decibel.
Given the following data:
Sound intensity = 52 dB.What is sound intensity?Sound intensity can be defined as a measure of the power of a sound wave per unit area. Thus, sound intensity is a quantity that can be used to measure the energy of sound and its unit of measurement is Watts per square meter.
How to calculate the sound intensity level.Mathematically, sound intensity level is given by this formula:
\(\beta = 10 log(\frac{I}{I_{ref}} )\)
Note: The reference value of sound intensity is equal to \(1.0 \times 10^{-12}\;W/m^2\)
Thus, the sound intensity for one (1) professor is given by:
\(I_1 = 1.0 \times 10^{-12} \times 10^{5.2}\\\\I_1=1.585 \times 10^{-7}\;W/m^2\)
For 100 professors, the sound intensity is:
\(I_{100} = 1.585 \times 10^{-7} \times 100\\\\I_{100}=1.585 \times 10^{-5}\;W/m^2\)
Substituting the parameters into the formula, we have;
\(\beta = 10 log(\frac{1.585 \times 10^{-5}}{1.0 \times 10^{-12}})\\\\\beta = 10 log(15.58 \times 10^{6})\\\\\beta = 10 \times 7.2\\\\\beta =72\;dB\)

One physics professor talking produces a sound intensity level of 52 dB. It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously?
Answer:
72dB
Explanation:
The sound intensity level of one prof is given, that's your β1 (which is equal to 52dB).
Using the sound intensity level formula:
β1= 10log (\(\frac{I}{I_{o} }\)) = 52 dB
*This will be useful later on [even if β1 is known]
Set up the formula for β2 (β2 is going to be the new sound intensity, the one for the 100 profs):
β2 = 10 log( \(\frac{ 100 I}{I_{o} }\) )
*You need to multiply the intensity of one professor by 100 (because now there's more)
*do some algebra- pull out the 100
β2 = 10 log (100 \(\frac{I}{I_{o} }\))
*use log laws
β2 = 10 ( log(100) + log (\(\frac{I}{I_{o} }\)) )
*Now, isn't there a familiar part? Well, yes! The expression for β1!
β2 = 10log(100) + β1
β2 = 10log(100) + 52dB
*use your calculator
β2 = 73dB
