According to Ohm's law  the the bulb which experience the greater resistance will be brightest in the series.

Ohm's law states that the voltage across a circuit is the product of the current and resistance through it.

Thus, V = IR.

As per this relation, the current and resistance through a circuit are in inverse relation whereas voltage with current and resistance are in direct proportionality.

As the resistance increases, the voltage drop increases, making the more light electrical energy is converted to light energy in bulbs make it brighter. Therefore, the bulb with higher resistance i. e 22 ohms would be the brightest.

To determine the reaction time for an individual using kinematics, we need to first collect data on the distance that the ruler falls and the time it takes for the individual to catch it. We can then use this data to calculate the reaction time for each trial.

Here is a data table that includes the distance the ruler falls and the corresponding reaction time for each trial:

Trial Distance (cm) Reaction Time (s)

1 48 0.80

2 41 0.68

3 29 0.48

4 41 0.68

5 40 0.67

6 42 0.70

To calculate the reaction time for each trial, we need to use the formula:

Reaction Time = √(2 * Distance / Acceleration Due to Gravity)

We can use this formula to calculate the experimental value for the acceleration due to gravity. We can then use this value to calculate the reaction time for each trial.

To calculate the experimental value for the acceleration due to gravity, we can use the following formula:

Acceleration Due to Gravity = (Distance / Reaction Time^2) / 2

Using this formula, we can calculate the experimental value for the acceleration due to gravity as follows:

Acceleration Due to Gravity = (48 / 0.80^2) / 2 = 9.60 m/s^2

Using this value for the acceleration due to gravity, we can then calculate the reaction time for each trial as follows:

Trial Distance (cm) Reaction Time (s)

The ball's parabolic motion causes it to move at a speed of 26.3 m/s right before it strikes the ground, which is faster than its straight-downfall velocity of 17.1 m/s.

How do you determine a golf ball's flight?

The vertical velocity of the ball traveling up the club head face is calculated using the equation 5/7 f v sin 0 where f is the fraction of speed left after the ball is compressed, 0 is the angle of the clubface at impact, and v is the velocity of the club head.

How will the ball's speed change as it descends to the ground?

The ball descends faster and faster. In other words, the ball is moving faster the entire time it is in the air, both during its ascent and at the moment it reaches its peak, as well as throughout its descent. Gravity is what causes the ball to accelerate.

The minimum potential difference between the filament and the target of the X-ray tube to produce X-rays with a wavelength of [tex]\(0.160 \, \text{nm}\)[/tex] is approximately [tex]\(7750 \, \text{V}\)[/tex].

The shortest wavelength [tex](\(\lambda_{\text{shortest}}\))[/tex] produced by the X-ray tube is approximately [tex]\(0.365 \, \text{nm}\)[/tex].

To calculate the minimum potential difference [tex](\(V\))[/tex] between the filament and the target of an X-ray tube to produce X-rays with a specific wavelength, we can use the equation for the energy of a photon [tex](\(E\))[/tex]:

[tex]\[E = \frac{hc}{\lambda}\][/tex]

Where:

[tex]\(h\)[/tex] is the Planck's constant [tex](\(6.626 \times 10^{-34}\) J·s)[/tex],

[tex]\(c\)[/tex] is the speed of light in a vacuum [tex](\(2.998 \times 10^8\) m/s)[/tex], and

[tex]\(\lambda\)[/tex] is the wavelength of X-rays [tex](\(0.160\) nm)[/tex].

We also know that the energy of a photon is related to the potential difference [tex](\(V\))[/tex] by the equation:

[tex]\[E = eV\][/tex]

Where:

[tex]\(e\)[/tex] is the elementary charge [tex](\(1.602 \times 10^{-19}\) C)[/tex].

Now, we can equate these two expressions for energy and solve for [tex]\(V\)[/tex]:

[tex]\[\frac{hc}{\lambda} = eV\]\\\\\V = \frac{hc}{e\lambda}\][/tex]

Substitute the given values:

[tex]\[V = \frac{(6.626 \times 10^{-34} \, \text{J·s}) \times (2.998 \times 10^8 \, \text{m/s})}{(1.602 \times 10^{-19} \, \text{C}) \times (0.160 \times 10^{-9} \, \text{m})}\][/tex]

[tex]\[V = \frac{1.9876 \times 10^{-15} \, \text{J·m}}{2.5632 \times 10^{-28} \, \text{C}}\]\\\\\V \approx 7750 \, \text{V}\][/tex]

So, the minimum potential difference between the filament and the target of the X-ray tube to produce X-rays with a wavelength of [tex]\(0.160 \, \text{nm}\)[/tex] is approximately [tex]\(7750 \, \text{V}\)[/tex].

Now, to find the shortest wavelength [tex](\(\lambda_{\text{shortest}}\))[/tex] produced by the tube, we can rearrange the equation for [tex]\(V\) in terms of \(\lambda\)[/tex]:

[tex]\[\lambda = \frac{hc}{eV}\][/tex]

Substitute the minimum potential difference [tex](\(V = 7750 \, \text{V}\))[/tex] into the equation:

[tex]\[\lambda_{\text{shortest}} = \frac{(6.626 \times 10^{-34} \, \text{J·s}) \times (2.998 \times 10^8 \, \text{m/s})}{(1.602 \times 10^{-19} \, \text{C}) \times (7750 \, \text{V})}\]\\\\\\lambda_{\text{shortest}} = \frac{1.9876 \times 10^{-15} \, \text{J·m}}{1.2385 \times 10^{-15} \, \text{C}}\][/tex]

[tex]\rm \[\lambda_{\text{shortest}} \approx 0.365 \, \text{nm}\][/tex]

If the velocity of moving body decreases by equal amounts in equal interval of time, it is said to have negative acceleration.

What is velocity?

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity. The standard unit of velocity magnitude is the meter per second (m/s).

What is acceleration?

Acceleration is the rate at which an object's velocity with respect to time changes. Negative acceleration is the acceleration that results when a moving object's velocity decreases. When a body's velocity is decreasing, it typically experiences negative acceleration. Given that the velocity is rising in that direction, its direction is the inverse of the body's motion.
