If the electric field is 108 n/c at a distance of 59 cm from a point charge q,  the charge on the point charge is 9.98 x \(10^{-19}\) Coulombs.

We can use the equation for the electric field produced by a point charge to find the charge:

E = k * q / \(r^{2}\)

where,

E = the electric field, equal to 108 N/C

k = the Coulomb constant, equal to 8.99 x \(10^{9}\) N \(m^{2}\) / \(C^{2}\)

q = the charge

r = the distance from the point charge, equal to 59 cm = 0.59 m

Rearranging the equation to solve for q, we get:

q = E * \(r^{2}\) / k

Plugging in the values, we get:

q = 108 N/C * \((0.59 m)^{2}\) / 8.99 x \(10^{9}\) N \(m^{2}\) / \(C^{2}\) )

q = 9.98 x \(10^{-19}\) C

So the charge on the point charge is 9.98 x \(10^{-19}\) C, or 9.98 x \(10^{-19}\) Coulombs.

If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.

\(s=\frac{d}{t}\)

The cheetah ran 112 meters in 4 seconds.

Substitute the values into the formula.

\(s=\frac{112 \ m}{ 4\ s}\)

Divide.

\(s= 28 \ m/s\)

The cheetah's speed is 28 meters per second and choice B is correct.

The incline angle should be about 4.7 degrees and the block's acceleration would be greater than that of the rolling sphere.

a) Let M be the mass of the sphere, R be its radius, and θ be the incline angle. When the sphere rolls down the incline without slipping, the friction force acting on it causes a torque about its center of mass, which results in a rotational acceleration. If a is the linear acceleration of the center of mass, and α is the angular acceleration, then we have:

a = α R

Also, the torque τ caused by the friction force is given by:

\(τ = I α\)

where I is the moment of inertia of the sphere about its center of mass. For a solid sphere, I is given by:

\(I = (2/5) M R^2\)

Since the sphere rolls without slipping, the friction force is related to the normal force N by:

\(f = μ N\)

where f is the friction force, and μ is the coefficient of static friction. The normal force is related to the weight of the sphere by:

N = M g cos θ

where g is the acceleration due to gravity.

The net force acting on the sphere down the incline is given by:

\(Fnet = M g sin θ - f\)

The linear acceleration of the center of mass is given by:

\(a = Fnet / M\)

Substituting for f and N, we get:

\(a = g (sin θ - μ cos θ)\)

Equating this to α R, we get:

g (sin θ - μ cos θ) = α R

Substituting for α using the expression for I and τ, we get:

\(g (sin θ - μ cos θ) = τ / (2/5 M R)\)

Substituting for τ using the expression for f and N, we get:

\(g (sin θ - μ cos θ) = (μ M g cos θ) R / (2/5)\)

Simplifying, we get:

\(tan θ = (5/7) μ\)

Substituting the given values, we get:

tan θ = (5/7) (0.23)

\(θ = arctan(0.082)\)

θ = 4.7 degrees (approximately)

Therefore, the incline angle should be about 4.7 degrees

b) Since the block is frictionless, its acceleration down the incline is given by:

a' = g sin θ

Substituting the value of θ obtained in part a), we get:

a' = g sin(4.7) ≈ 0.41 g

Since this is greater than 0.23g, the block's acceleration would be greater than that of the rolling sphere.

Answer:

As the color of light changes from red to yellow, the frequency of the light increases.

Explanation:

Red light has the longest wavelength and the lowest frequency among visible light, while yellow light has a shorter wavelength and a higher frequency.

The relationship between the frequency and the wavelength of light is given by the equation:

c = λν

where c is the speed of light, λ is the wavelength of light, and ν is the frequency of light.

Since the speed of light is constant in a vacuum, if the wavelength of light decreases as the color changes from red to yellow, then the frequency must increase. This means that yellow light has a higher frequency than red light.

The spring compresses in stopping the mass will be 11.44 cm.

To determine the compression of the spring when stopping the mass, we need to consider the conservation of mechanical energy.

The initial kinetic energy (KE) of the mass is given by:

KE = (1/2)mv²

KE = 0.5 * 2.5 * 1.2²

KE = 1.8 m/s                               ...{1}

The final potential energy stored in the spring (PE) is equal to the initial kinetic energy.

PE = μmgx + (1/2)kx²

PE = 0.35 * 2.5 * 9.8x + 0.5 * 125x²

PE = 8.575x + 62.5x²                    ...{2}

You were approximately 5.72 meters away from the second baseman. The vertical drop or distance between point A and point B was approximately 0.4576 meters.

To determine the distance between you (the shortstop) and the second baseman, we can use the formula for horizontal distance (d) traveled by an object moving at a constant horizontal velocity:

d = v * t

where:

- d is the horizontal distance traveled,

- v is the horizontal velocity of the ball,

- t is the time taken.

Given that the horizontal velocity (v) is 13 m/s and the time (t) is 0.44 s, we can calculate the horizontal distance (d) as follows:

d = 13 m/s * 0.44 s = 5.72 meters

So, you were approximately 5.72 meters away from the second baseman.

To find the vertical drop or the distance between point A and point B, we need to calculate the vertical component of the ball's motion. Since the ball is thrown horizontally, it will experience a constant vertical acceleration due to gravity.

The formula to calculate the distance (d) traveled vertically in free fall is:

d = 1/2 * g * t²

where:

- d is the vertical distance traveled,

- g is the acceleration due to gravity (approximately 9.8 m/s²),

- t is the time taken.

Given that the time (t) is 0.44 s, we can calculate the vertical distance (d) as follows:

d = 1/2 * 9.8 m/s² * (0.44 s)² = 0.4576 meters

Elasticity is of significant importance in the everyday lives of businesses and consumers as it helps them understand and respond to changes in prices and demand for goods or services. By considering elasticity, businesses can make informed decisions regarding pricing strategies, production levels, and resource allocation. Consumers, on the other hand, can assess the impact of price changes on their purchasing decisions and adjust their consumption patterns accordingly.

Elasticity, specifically price elasticity of demand, measures the responsiveness of consumer demand to changes in price. It indicates the percentage change in quantity demanded resulting from a one percent change in price. Understanding price elasticity allows businesses to determine how sensitive consumers are to changes in price and adjust their pricing strategies accordingly.

For example, let's consider the market for gasoline. Gasoline is a highly price-sensitive good, meaning that changes in its price have a significant impact on consumer demand. If the price of gasoline increases, consumers may reduce their consumption and seek alternatives such as carpooling or using public transportation. In this scenario, businesses need to consider the price elasticity of gasoline to predict and respond to changes in consumer behavior. They might lower prices to stimulate demand or introduce more fuel-efficient options to cater to price-conscious consumers.

In conclusion, elasticity matters because it provides valuable insights into the dynamics of supply and demand, enabling businesses and consumers to make informed decisions in response to price changes. By understanding elasticity, businesses can adapt their strategies to maintain competitiveness, while consumers can optimize their purchasing choices based on price sensitivity.

The total charge of all the electrons in a 22 kg bar of aluminum is approximately 7.854 × 10^7 Coulombs.

The total charge of all the electrons in a 22 kg bar of aluminum can be calculated by first finding the number of aluminum atoms in the bar and then multiplying it by the charge of each electron.
To find the number of aluminum atoms, we need to know the molar mass of aluminum. The atomic mass of aluminum is given as 27 u.
Using the atomic mass, we can calculate the molar mass of aluminum. The molar mass of aluminum is equal to the atomic mass in grams per mole. Therefore, the molar mass of aluminum is 27 g/mol.

Next, we need to calculate the number of moles of aluminum in the bar. This can be done by dividing the mass of the bar (22 kg) by the molar mass of aluminum (27 g/mol).
22 kg is equal to 22,000 g, so the number of moles of aluminum in the bar is:
Number of moles = 22,000 g / 27 g/mol ≈ 814.81 mol
Since there are 13 electrons per aluminum atom, we can now calculate the total number of electrons in the bar by multiplying the number of moles by Avogadro's number (6.022 × 10^23 electrons/mol).
Total number of electrons = 814.81 mol × 6.022 × 10^23 electrons/mol ≈ 4.909 × 10^26 electrons
Finally, we can calculate the total charge of all the electrons by multiplying the total number of electrons by the charge of each electron (1.6 × 10^-19 C).
Total charge = 4.909 × 10^26 electrons × 1.6 × 10^-19 C/electron ≈ 7.854 × 10^7 C
