The vertical displacement D(t) between two jumping basketball players can be found using the kinematic equation for vertical motion. By accounting for the later jump time of the second player, we can subtract their height functions to find the displacement as a function of time in terms of initial height H, gravitational acceleration g, and time t.

The student's question involves calculating the vertical displacement of two basketball players, Arabella and Boris, during their jumps, with Arabella starting her jump before Boris. To find the vertical displacement D(t) as a function of time, we need to consider the kinematic equation for vertical motion H(t) = V0t - (1/2)gt2, where V0 is the initial vertical velocity, g is the acceleration due to gravity (9.8 m/s2), and t is the time.

Assuming both players have the same V0 and are affected by the same g, the displacement of each player at any time t is given by:

Given that Boris starts jumping at time tr later than Arabella, his height function H(b) has t - tr. The vertical displacement D(t) between Arabella and Boris from 0 < t < tr can be found by subtracting the height of Boris from the height of Arabella:

D(t) = H(a)(t) - H(b)(t)

Substituting in the expressions for H(a)(t) and H(b)(t) gives us the final expression for D(t) in terms of the known quantities H, g, and t.

Answer: B on edg

Explanation:

Acceleration is the rate at which velocity changes when direction is involved, and the rate at which speed changes when there is no directional change.

When motion is changing directions, acceleration is the rate at which velocity changes, but when motion is not changing direction, acceleration may be expressed as the rate at which speed changes.

Acceleration is defined as the time rate of change of velocity, which includes both the magnitude and direction of the velocity vector. Therefore, when an object changes its direction, even if maintaining a constant speed, it is still undergoing acceleration because its velocity vector is changing. However, when the direction is constant and only the speed changes, acceleration refers to the rate of this change in speed.

A force that holds atoms together is a chemical "bond".

Chemical bonds hold atoms together and make brief associations that are fundamental to life. Sorts of chemical bonds including covalent, ionic, and hydrogen bonds and London dispersion forces.  

The chemical bond can be thought of as a power that holds the particles of different components together in such compounds. It opens up the likelihood of a huge number of mixes of the components, and the formation of a large number of new compounds.

Answer:

a = - 6 m/s/s

here negative sign shows that velocity is decreasing with time

Explanation:

As we know that average acceleration is given by

[tex]a_{avg} = \frac{v_f - v_i}{\Delta t}[/tex]

here we will have

[tex]v_f[/tex] = final speed = 0 m/s

[tex]v_i[/tex] = initial speed = 9 m/s

[tex]\Delta t[/tex] = time interval = 1.50 s

now from above equation we will have

[tex]a = \frac{0 - 9}{1.5}[/tex]

[tex]a = - 6 m/s^2[/tex]

so average acceleration will be -6 m/s/s

Final answer:

To convert the energy usage of a refrigerator from kWh to J, kJ, and Cal, we multiply by appropriate conversion factors. The refrigerator uses 2.556 × 10^9 J, 2.556 × 10^6 kJ, and approximately 610,868 Cal per year. At an electricity cost of $0.15 per kWh, it costs $106.50 per year to run.

Explanation:

To answer the question on how to convert the annual energy usage of a frost-free refrigerator from kilowatt-hours (kWh) to Joules (J), kilojoules (kJ), and Calories (Cal), we can use the following conversion factors:

1 kWh = 3.6 × 10^6 J (Joules)

1 J = 0.001 kJ (kilojoules)

1 Cal = 4.184 kJ (the food Calorie, with a capital 'C', is equivalent to a kilocalorie)

Now, we will convert the 710 kWh/year:

To Joules: 710 kWh × 3.6 × 10^6 J/kWh = 2.556 × 10^9 J

To kilojoules: 2.556 × 10^9 J × 1 kJ/1000 J = 2.556 × 10^6 kJ

To Calories: Using the relationship between kJ and Cal: 2.556 × 10^6 kJ / (4.184 kJ/Cal) ≈ 610,868 Cal

The cost to run such a refrigerator at a typical electricity cost of $0.15 per kWh can be calculated as follows:

Annual Cost = 710 kWh/year × $0.15/kWh = $106.50/year

Answer:

Lenz's law

Explanation:

Lenz's Law states that the induced tensions will be such that they oppose the variation of the magnetic flux that produced them; However, this law is a consequence of the principle of conservation of energy.

Lenz's Law: "The sense of the currents or induced electromotive force is such that it always opposes the cause that produces it, that is, the variation of the flow."

Thanks to the already named Lenz Law, the Faraday Law was completed, so it is common to also call it the Faraday-Lenz Law to honor its efforts in the problem, Russian physicists always use the name "Faraday-Lenz Law ".

Temperature measures the average kinetic energy of the motion of molecules within an object. This means the faster the average molecular motion, the higher the temperature.

is the energy of motion. Every molecule in an object is in motion and hence possesses some kinetic energy. This motion could be translational (moving from one place to another), vibrational (moving back and forth), or rotational (spinning). The more kinetic energy they have, the faster they are moving, and the higher the temperature of the object. It's important to note that we are talking about the

The value of ΔH for this process is 1.519 kJ.

To calculate the value of ΔH for a process, we need to consider the heat absorbed or released and the work done on or by the system.

In this case, the gas absorbs 829J of heat from its surroundings and has 0.69kJ of P−V work done on it by its surroundings.

The ΔH for this process can be calculated as ΔH = q + w, where q represents the heat absorbed or released and w represents the work done on or by the system. Therefore, ΔH = 0.829 kJ + 0.69 kJ = 1.519 kJ.

The sum of all outputs must equal the input.

Explanation:

The work done by a person using a force of 25 N to move a desk 3.0 m is 75 Joules, calculated by multiplying the force and the distance.

The concept in question is related to work and energy, under Physics. The work done by a force is defined as the product of the force and the distance over which the force acts, given by the formula: Work = Force x Distance. This implies that the work done is equal to the value of the force (in newtons) multiplied by the distance (in meters) over which the force is applied. In this case, a force of 25 N is acting to move a desk over a distance of 3 m. The work done can be calculated by multiplying the force and the distance: 25 N x 3 m = 75 J (Joules).

Answer : Wavelength.

Explanation :

A disturbance created in a medium produces wave.

In transverse wave, the particles of the medium moves in the direction perpendicular to the direction of propagation of wave.

The uppermost portion of the wave is called the crest and the lower most portion is called the trough.

In longitudinal wave, the particles of medium moves in the same direction of wave i.e. in the direction parallel to the wave.

The particles of medium in longitudinal wave forms compressions and rarefactions. In compression the density of particles in more in a particular space while in rarefaction it is less.

Hence, the wavelength is the the distance between two crests or two troughs on a transverse wave.

It is also the distance between compressions or the distance between rarefactions on a longitudinal wave.

Answer:

The correct answer is: It acts perpendicular to the velocity and is directed toward the center of the circle.

Explanation:

The Centripetal Force is when an object that describes a circular path has the feeling that it is carried inside the center of the circumference described. This indicates that the centripetal force acts with attraction on the body, indicating the directions that it must take.

In other words, the centripetal force is the force that acts on a moving object on a curvilinear path, and that is directed towards the center of path curvature.

When the object moves in a curvilinear direction, the centripetal force will always act perpendicular to the known direction, that is, it always acts perpendicular to the direction of movement of the body on which it is applied.

Given all this, it is possible to say that the correct answer is: It acts perpendicular to the velocity and is directed toward the center of the circle.

The maximum power in the external resistor R, when connected to a battery of E volts and internal resistance r, occurs when R equals r. This is a principle of electrical power in physics.

This is a physics question involving a fundamental concept in electrical power and Ohm's Law. The given formula P = E^2R/(R+r)^2 is the power delivered to an external resistor R when it is connected to a battery with electromotive force (E) and internal resistance (r).

To find the maximum power in the external resistor R, we would differentiate the formula with respect to R and equal it to zero (since the maximum or minimum of a function translates to a derivative of zero). By doing this, R would be equal to r.

Therefore, the maximum power is distributed to the external resistor when the value of the resistor (R) equals the internal resistance (r).

Final answer:

The net force exerted on a tennis ball being served, which accelerates from rest to 36 m/s over a distance of 35 cm, is approximately 107.05 N.

Explanation:

To determine the magnitude of the net force acting on a tennis ball being served, we first need to calculate the acceleration of the ball. With an initial speed (vi) of 0 m/s, a final speed (vf) of 36 m/s, and a distance (d) of 0.35 m over which the acceleration occurs, we can use the kinematic equation vf^2 = vi^2 + 2ad to solve for acceleration (a).

vf^2 = 2ad → a = vf^2 / (2d) → a = (36 m/s)^2 / (2*0.35 m) → a ≈ 1845.71 m/s2.

Using this acceleration and the mass of the ball (m), we can then apply Newton's second law, Fnet = ma, to find the net force. The mass of the tennis ball is 0.058 kg (58 g). Thus, Fnet = ma = 0.058 kg * 1845.71 m/s2 → Fnet ≈ 107.05 N.

So, the net force exerted by the racket on the tennis ball is approximately 107.05 N.
