Does a game ends when a player gets 10 or wins by 2? yes or no in ping pong

Answer:

See the answers below.

Explanation:

The total power of the circuit is equal to the sum of the powers of each lamp.

\(P=60+100\\P=160 [W]\)

Now we have a voltage source equal to 240 [V], so by means of the following equation we can find the current circulating in the circuit.

\(P=V*I\)

where:

P = power [W]

V = voltage [V]

I = current [amp]

\(I = P/V\\I=160/240\\I=0.67 [amp]\)

So this is the answer for c) I = 0.67 [amp]

We know that the voltage of each lamp is 240 [V]. Therefore using ohm's law which is equal to the product of resistance by current we can find the voltage of each lamp.

a)

\(V=I*R\)

where:

V = voltage [V]

I = current [amp]

R = resistance [ohms]

Therefore we replace this equation in the first to have the current as a function of the resistance and not the voltage.

\(P=V*I\\and\\V = I*R\\P = (I*R)*I\\P=I^{2}*R\)

\(60 = (0.67)^{2}*R\\R_{60}=133.66[ohm] \\and\\100=(0.67)^{2} *R\\R_{100}=100/(0.66^{2} )\\R_{100}=225 [ohm]\)

b)

The effective resistance of a series circuit is equal to the sum of the resistors connected in series.

\(R = 133.66 + 225\\R = 358.67 [ohms]\)

If two balls are projected with initial velocity v and 2v respectively, the ball that is projected with a velocity of 2v would reach the ground first.

The term projectile has to do with the kind of motion that uses a parabolic path. The parabolic path is a path that is curved. For instance, if you trough a ball from one point to the other, the ball does not follow a straight path, the path of the ball is curved.

The time that it takes for the ball to reach the ground from the point of projection is dependent on the initial velocity of the ball. Thus, if the ball has been projected with a higher initial velocity then the ball would reach the ground faster and vice versa.

Thus, given that the velocity 2v is twice the velocity v, the ball that is projected at this velocity would reach the ground first.

Orchids have six petals arranged in a 3-2-1 arrangement.

Orchids have three sepals (one dorsal and two lateral) and three petals, but usually the middle petal, the labial, is distinct from the other petals. In most orchids, the flower rotates 180° during growth, so the lip is the lowest of the petals and points upwards. There are three sepals that are the outer petals. This is what you see when you look at an unopened bud. He also has three petals, but one of his orchid petals is specialized for the lip. Orchids always have three petals. Two are "normal" and the third is a highly specialized structure called a lip.

The relative motion of gaseous particles increases with increase in the temperature of the gas molecules just like the motion of popcorn in a popper increases when heat is applied to the popper.

The kinetic theory of gases or matter states that matter consists of tiny particles which are constant motion, colliding with one another and with walls of the containing vessels.

Just like a popcorn in a popcorn popper pops when heat is applied to the popper, gases contained in a cylinder increases their speed when they acquire more kinetic energy as the temperature of the cylinder increases.

Thus, the motion of gas particles depends on the temperature of the containing vessel so also does the random motion of popcorn depends on the temperature of the popper.

To determine the minimum height of a vertical flat mirror for a person, we can use a ray diagram. The person's eye level should be at the same height as the top of mirror. Considering the person's height as 174 cm, the minimum height of the mirror should be 174 cm.

Vertical is a term used in geometry and physics to describe an orientation or direction perpendicular to the horizontal plane or ground level. It is typically aligned with the force of gravity, pointing upward or downward. In two-dimensional space, vertical refers to the y-axis, while in three-dimensional space, it can refer to the z-axis. Vertical motion is governed by gravity, resulting in objects falling toward the ground or rising upward when lifted. Vertical lines or planes have no slope, and any two points on them have the same x-coordinate or y-coordinate.

The finite-difference formulation of the one-dimensional heat conduction problem in a pin fin with constant diameter and thermal conductivity, losing heat by convection and radiation, can be used to determine the temperatures T1 and T2 at the middle and tip nodes of the fin, respectively, given a specified temperature at the base node and negligible heat transfer at the tip node.

The finite-difference formulation involves discretizing the differential equation governing heat transfer into a set of algebraic equations that can be solved numerically. For this problem, the energy balance equation at node i can be written as:

(Ti+1 - Ti)/Δx - (Ti - Ti-1)/Δx = hP/A(T∞ - Ti) + εσP/A(Tsur - Ti)

where Ti is the temperature at node i, P is the perimeter of the fin, A is the cross-sectional area of the fin, h is the convection coefficient, T∞ is the ambient temperature, ε is the emissivity of the fin, σ is the Stefan-Boltzmann constant, and Tsur is the average temperature of the surrounding surfaces.

Using the boundary conditions of Ti = T0 at i = 0 and (Ti+1 - Ti)/Δx = 0 at i = n, where n is the number of nodes, we can solve the system of equations to obtain the temperatures T1 and T2.

This finite-difference formulation provides a numerical solution for the temperatures at different nodes of the pin fin, taking into account the effects of convection and radiation on heat transfer.

The current through the wire segment is determined by the right-hand rule, while the force exerted is determined by the left-hand rule.

The direction of the current through the wire segment nearest the magnet can be determined using the right-hand rule. If we point our right thumb in the direction of the magnetic field created by the magnet, and then curl our fingers around the wire, the direction in which our fingers curl represents the direction of the current. The specific direction will depend on the orientation of the magnet's poles and the wire.

The direction of the force exerted by the magnet on the wire segment can be determined using the left-hand rule. If we extend our left hand, with the thumb pointing in the direction of the current flowing through the wire, and the fingers pointing in the direction of the magnetic field created by the magnet, the palm of our hand will indicate the direction of the force.

The force exerted by the magnet on the wire segment will be perpendicular to both the current and the magnetic field, and its specific direction will depend on the orientation of the magnet's poles and the wire.

It's important to note that the specific directions will vary depending on the orientation and configuration of the magnet and the wire in the given setup.

a. a listener on the ground

Explanation:

When a jet travels through the air, it produces sound waves that travel through the air and create sound waves in the surrounding atmosphere. These sound waves are called sonic booms. As a jet travels through the air, it produces sound waves that travel through the air and create sound waves in the surrounding atmosphere.

When the jet travels at or above the speed of sound, it creates a loud, thunderous boom that can be heard on the ground. This is because the sound waves created by the jet are traveling faster than the speed of sound, creating a sonic boom that travels through the air and can be heard by a listener on the ground.

Since the horizontal component of the velocity is zero, the factor that is responsible for the two balls to reach the ground at the same time will be  the vertical velocities of the balls. The correct option is C

When an object is thrown from a tower, and at the same time another object is dropped vertically, both objects will reach the ground at the same time. This occurs because of gravity.

Given that Rob and his sister Joan are standing on their apartment balcony. Rob throws a ball straight out from the balcony. At the same time, Joan drops a ball straight down. Both balls reach the ground at the same time.

They will both reach the ground at the same time because the component of motion under gravity is independent of the component perpendicular to it. Then, the horizontal component of the velocity will be zero.

Since the horizontal component of the velocity is zero, the factor that is responsible for the two balls to reach the ground at the same time will be  the vertical velocities of the balls

In words, the R2 of 0.27 means that 27% of the variability in y (24-hour urinary Na) can be explained by x (estimated 24-hour urinary Na) obtained from casual urine specimens at one point in time.

The INTERSALT Study was designed to investigate the relationship between dietary sodium and blood pressure (hypertension) in populations worldwide.

The study included 10,079 men and women from 52 population samples in 32 countries. One of the goals of the study was to quantify the relationship between 24-hour urinary Na (y) and estimated 24-hour urinary Na (x) obtained from casual urine specimens at one point in time.

The investigators presented a simple linear regression of y on x, separately for men and women. The regression equation for men was: Y = 1.03x + 7.19, with R2 = 0.27, n = 1369.

The coefficient of determination, R2, is a statistical measure that represents the proportion of the variance for a dependent variable (y) that's explained by an independent variable (x) or variables in a regression model.

In this case, the R2 of 0.27 means that 27% of the variability in y (24-hour urinary Na) can be explained by x (estimated 24-hour urinary Na) obtained from casual urine specimens at one point in time. The remaining 73% of the variability in y is due to other factors that are not included in the regression model.
