Dolasetron (anzemet) is an antiemetic. The concentration is 20 mg/ml. A nauseous 7 weekold 4 kg pitbull puppy named ""Spot"" needs a dose at 0.6 mg/kg IV. How many mg will ""Spot""be given? How many ml?

A call can supply circuit of 0. 4A and 0. 2A through a 4ohms and 10 ohms resistor respectively what is the internal resistant of the cellThe internal resistance of the cell is 3 ohms.

According to Ohm's Law, the current in a circuit can be determined using the equation I = V/R, where I is the current, V is the voltage, and R is the resistance. In this case, we have two resistors connected in parallel. Let's assume the voltage of the cell is V.

For the 4-ohm resistor, the current is given as 0.4A. Using Ohm's Law, we can calculate the voltage across the resistor as V1 = I1 * R1 = 0.4A * 4ohms = 1.6V.

For the 10-ohm resistor, the current is given as 0.2A. Using Ohm's Law, we can calculate the voltage across the resistor as V2 = I2 * R2 = 0.2A * 10ohms = 2V.

Since the resistors are in parallel, the voltage across both resistors is the same, so V1 = V2. This means the internal resistance of the cell can be calculated as V = I * r, where r is the internal resistance. Substituting the values, we have 1.6V = 0.4A * r, which gives us r = 1.6V / 0.4A = 4 ohms.

The right-hand rule is used in the field of electromagnetism. It is a method for determining the direction of a magnetic field related to the direction of the electric current that is creating it.

The right-hand rule is also used to determine the direction of the force on a charged particle moving in a magnetic field. There are two types of right-hand rules in electromagnetism: the right-hand rule for magnetic field direction and the right-hand rule for force direction. The correct statement regarding applying the right-hand rule is that if we hold a current-carrying conductor in the right hand, then the direction of the thumb points towards the direction of the current, then the curling of the fingers represents the direction of the magnetic field around the conductor. This means that if the current flow is in the upward direction in the conductor, then the magnetic field is in the counterclockwise direction around the conductor, and if the current is flowing in the downward direction, then the magnetic field is in the clockwise direction around the conductor. In the case of a loop conductor, we can determine the direction of the magnetic field inside the loop by using the right-hand rule. In this case, if we wrap the fingers of the right hand around the loop in the direction of the current flow, then the direction in which the thumb points gives us the direction of the magnetic field inside the loop. The right-hand rule is a very useful tool in understanding and visualizing the interactions between electric currents and magnetic fields. It is also an essential tool for designing and building electrical devices such as motors and generators. The right-hand rule is a fundamental concept in electromagnetism and is used extensively in many areas of science and engineering.

In the experiment, measuring the total time for 20 complete revolutions and dividing it by 20 to obtain the period of rotation is done to reduce errors and improve the accuracy of the measurement.

Measuring the time for one complete revolution directly can be subject to human reaction time and potential errors in starting and stopping the stopwatch precisely at the beginning and end of each revolution. These errors can accumulate and affect the accuracy of the measurement.

By measuring the total time for 20 complete revolutions and then dividing it by 20, we are essentially averaging out these potential errors over multiple revolutions. This helps to minimize the impact of any individual timing error and provides a more reliable and accurate measurement of the period of rotation.

Additionally, by taking multiple measurements (in this case, 20), we increase the sample size and reduce the influence of outliers or irregularities in any individual measurement. This improves the overall precision and reliability of the calculated period.

Therefore, measuring the total time for multiple revolutions and dividing by the number of revolutions allows for a more accurate determination of the period of rotation in the experiment.

The maximum height of the stone is approximately 1.27 meters and the range is approximately 2.04 meters.

To find the maximum height and range of a projectile, we need to consider the motion of the object in the x and y directions.

Given that the initial velocity of the stone is (4i + 5j), we can break it down into its x and y components:

Initial velocity in the x direction (Vx) = 4

Initial velocity in the y direction (Vy) = 5

To determine the resultant force acting on the object we need to find the net displacement. We can find the net displacement by subtracting the total distance travelled in the opposite direction (west) from the total distance travelled in the east direction. We can use this formula: Net displacement = Total displacement in the East direction - Total displacement in the West direction. Once we find the net displacement we can calculate the resultant force acting on the object.

The athlete runs 150m towards east, 70m towards west and again 100m towards east. Thus, total displacement in the East direction = 150m + 100m = 250mTotal displacement in the West direction = 70mNet displacement = Total displacement in the East direction - Total displacement in the West direction= 250m - 70m= 180mTherefore, the net displacement of the athlete is 180m towards east.

This displacement is called as the resultant displacement. Since the athlete has been moving towards east in the positive direction and towards west in the negative direction, thus his resultant displacement is the sum of the positive and negative distances he covered.

Inertia refers to the natural tendency of every object to resist any change in either speed or direction. Every object tends to maintain its state of motion until an external force acts on it.

Inertia is an essential concept in physics, and it can be observed in everyday life. Here is how you can observe inertia in your everyday life:

When you are in a moving car, and the driver suddenly stops, your body tends to move forward. This is because of inertia. Your body is already in motion, and when the car stops, your body tends to keep moving in the same direction. The seatbelt helps to prevent this movement by exerting a force on your body in the opposite direction.

When you are on a merry-go-round and it starts spinning, you tend to feel a force pushing you away from the center of the ride. This is also due to inertia. Your body is already in motion, and when the ride starts spinning, your body tends to keep moving in the same direction. The force that pushes you away from the center of the ride is known as the centrifugal force.

When you are playing a game of pool, and you hit the cue ball, it tends to keep moving until it comes into contact with another ball or hits the wall of the table. This is also due to inertia.

The final momentum of the system can be calculated as:pf = (m + M)V. Here, V is the common velocity of masses m and M after the impact, which can be calculated using the principle of conservation of mechanical energy.

As the given system of masses is an example of an inelastic collision, some energy is lost during the impact due to deformation of the masses. Therefore, the conservation of mechanical energy can be written as:

1/2 mv² = (1/2) (m + M) V²

Solving for V, we get:V² = mv² / (m + M)V = v * sqrt(m / (m + M))

Therefore, the final momentum of the system can be calculated as:pf = (m + M) v * sqrt(m / (m + M)) = v * sqrt(m (m + M))

Therefore, applying the principle of conservation of linear momentum, we have:pi = pfmv = v * sqrt(m (m + M))v = mv / sqrt(m (m + M))

Hence, the common velocity of masses m and M after the impact is v = mv / sqrt(m (m + M)).
