an electron at point p feels an electric force in the -z direction. the electron is now removed and all other charges in the system remain at the same position as before. what is the direction of the electric field at point p?
The direction of the electric field at point P is still in the -z direction, even after the electron is removed.
If an electron at point P feels an electric force in the -z direction, it means that there is an electric field at point P in the -z direction. The electric field at any point in space is defined as the force that a positive test charge would experience if it were placed at that point. In this case, the negative charge of the electron experiences a force in the opposite direction to the electric field because it has a negative charge.
When the electron is removed from point P, the electric field at that point does not change because the other charges in the system remain at the same position as before. This is because the electric field at a point in space is determined by the distribution of charges in the vicinity of that point, and not by the presence or absence of a particular charge at that point.
Therefore, the direction of the electric field at point P is still in the -z direction, even after the electron is removed.

A simple circuit contains a battery and a resistor.
Over 3.0 hours, 29 000 C of charge passes through the resistor.
Calculate the current flowing through the circuit during this time.
Give your answer to two significant figures.
Answer:
Approximately \(2.69\; {\rm A}\).
Explanation:
Ensure that all values are measured in standard units. Charge should be measured in coulombs, while time should be measured in seconds:
\(\begin{aligned}t &= 3.0\; {\rm hr} \times \frac{3600\; {\rm s}}{1\; {\rm hr}} = 10800\; {\rm s}\end{aligned}\).
Electric current \(I\) is the rate of flow of electric charge.
In order to find the electric current, divide electric charge \(q\) by the time \(t\) required to transfer these charge. If charge \(q\!\) is measured in coulombs and time \(t\!\) is measured in seconds, the unit of current \(I\)would be amperes:
\(\begin{aligned}I & = \frac{q}{t} \\ &= \frac{29000\; {\rm C}}{10800\; {\rm s}} \approx 2.69\; {\rm A}\end{aligned}\).
calculate the molar mass of a gas at 78 c and 560 torr if 206 ng occupies 0.206 ul. round your answer to significant figures.
The molar mass of a gas at 78 c and 560 torr if 206 ng occupies 0.206 ul is 41.64 g/mol
The molar mass of a gas can be calculated using the ideal gas law equation and the given values of temperature, pressure, mass, and volume.
To calculate the molar mass of a gas, we can use the formula:
Molar mass = (mass of gas) / (number of moles of gas)
First, we need to determine the number of moles of gas. We can use the ideal gas law equation:
\(PV = nRT\)
where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
We are given the temperature as 78 °C, which needs to be converted to Kelvin by adding 273.15:
T = 78 + 273.15 = 351.15 K
The pressure is given as 560 torr, and the volume is given as 0.206 µl.
Next, we can calculate the number of moles using the ideal gas law equation:
\(n = (PV) / (RT)\)
(0.5105 atm)(2.06×10⁻⁷ L) = n(0.0821 L-atm/mol-K)(318 K)
n = 4×10⁻⁹ mol
Molar mass = Mass/n = 2.06×10⁻⁷ g/4×10⁻⁹ mol
Molar mass = 41.64 g/mol
Now that we have the number of moles, we can calculate the molar mass by dividing the mass of the gas (given as 206 ng) by the number of moles.

What is the direction of the electric field at the center of the square, due to the four corner charges?
The direction of the total electric force on the charge q at the center of the square is downwards while at the center of the square, due to the four corner charges is inwards.
Given that the charge on a point at the center of square = q
The charge on leftmost points on the square = q_n
The charge on two rightmost points of square = q_p
If we assume that the charge on the center point of square is negative then,
a.) The direction of the total electric force on the charge q at the center of the square is downwards, that is towards the bottom of the square.
As the two leftmost charges have the same negative charge q_n and the two rightmost charges have the same positive charge q_p, they are repulsive to each other due to which the total electric force on the center charge q is a downward force while the direction of force on positive charges is upwards. Since the downward force is greater than the upward force, the total electric force is downwards.
b.) Due to the negative charge of the center charge q, the electric field from the two leftmost charges will be directed inward, and the electric field from the two rightmost charges will be directed outward. As the outward electric field is weaker than inward electric field, the net electric field at the center of the square will be directed inward.

Behaviors never come back once they have been extinguished. Please select the best answer from the choices provided T F
Answer:
False.
Explanation:
Behavior modification is a therapeutic process that is focused on changing any undesirable negative behavior in an individual through the use of positive or negative consequence and biofeedback.
This simply means that, behavior modification typically involves the process in which a desired behavior is reinforced while withholding reinforcement for any undesired behaviors.
Behavior modification is typically based on operant conditioning principles, through negative or positive reinforcement, undesirable behaviors developed by an individual are mainly replaced with more desirable ones.
Hence, behavior modification can be used to correct human behaviors or disorders such as enuresis (bed-wetting), Obsessive-Compulsive Disorder (OCD), generalized anxiety disorder, Attention-Deficit/Hyperactivity Disorder (ADHD), phobias, etc.
However, behaviors can still come back or be exhibited by an individual even if they have been extinguished through operant conditioning.
Operant conditioning can be defined as an associative learning process which involves reinforcing the strength of a behavior.

a bicycle wheel with a radius of 0.31 m rotates with an angular speed of 21 rad/s about its axle, which is at rest. What is the linear speed of a point on the rim of the wheel
Answer:
The linear speed is 6.51 m/s
Explanation:
Uniform Circular Motion
It's a movement of an object along the circumference of a circle. It can also be defined as a rotation along a circular path.
The angular speed can be calculated as follows:
\(\displaystyle \omega=\frac{v}{r}\)
Where:
v = tangential or linear speed
r = radius of the circle described by the rotating object
To calculate the linear speed, solve for v:
\(v = \omega\cdot r\)
\(v = 21\ rad/s\cdot 0.31\ m\)
\(v = 6.51\ m/s\)
The linear speed is 6.51 m/s

Which form of heat transfer occurs through fluid motions?
"The type of heat transfer that occurs through fluid motions is known as convection."
Convection, which is the extensive movement of molecules within gases and liquids, is the mechanism through which heat is transported. Conduction is used to move heat from the object to the fluid initially, but fluid motion is responsible for the bulk of the heat transfer.
Forced convection is the term for the movement of fluid caused by an external source (such as a fan, blower, etc.), while natural or free convection refers to the movement of fluid that occurs naturally. This type of heat transfer occurs only when the fluid is in motion.

a. The kinetic energy decreases and the potential energy increases.
b. The kinetic energy increases and the potential energy increases.
c. The kinetic energy increases and the potential energy decreases.
d. The kinetic energy decreases and the potential energy decreases.
As the rollercoaster moves from point A to point B, the correct answer is option c: The kinetic energy increases and the potential energy decreases.
At point A, the rollercoaster is at its highest position, which corresponds to the maximum potential energy and minimum kinetic energy. As the rollercoaster moves downwards towards point B, it gains speed and its height decreases.
This results in a decrease in potential energy since the height is decreasing. At the same time, the rollercoaster's speed increases, leading to an increase in kinetic energy.
The conservation of energy principle states that the total mechanical energy (the sum of potential energy and kinetic energy) of a system remains constant in the absence of external forces.
In this case, as the rollercoaster moves from point A to point B, the decrease in potential energy is equal to the increase in kinetic energy, keeping the total mechanical energy constant.
