Technician a says kinetic friction changes kinetic energy into thermal energy. technician b says static friction holds the car in place when it is stopped. Both A and B are correct.
What is kinetic and static friction?In static friction, there is found to be some frictional force that tends to resists force that is known to be applied to an object, and the object will be at the same sport at rest until the force of static friction is known to be overcome.
In kinetic friction, the frictional force is one that tend to resists the movement of an object.
Therefore, Technician a says kinetic friction changes kinetic energy into thermal energy and technician b says static friction holds the car in place when it is stopped. Both A and B are correct.

Relay contacts that are defined as being normally open (n.o.) have contacts that are:_____.
Relay contacts that are defined as being normally open (n.o.) have contacts that are open only if the relay coil is known to have de-energized.
What is meant by normally open contacts?Normally open (NO) are known to be open if there is no measure of current that is flowing through a given coil but it often close as soon as the coil is said to be energized.
Note that Normally closed (NO) contacts are said to be closed only if the coil is said to be de-energized and open only if the coil is said to carry current or is known to have energized.
The role of relay contact is wide. The Relays are tools that are often used in the work of switching of control circuits and it is one that a person cannot used for power switching that has relatively bigger ampacity.

What differences would rutherford have observed if he used aluminum foil instead of gold foil?.
The differences which Rutherford would have observed if he used aluminum foil instead of gold foil are: More of the particles would have passed through the aluminum foil unobstructed, and less would have been deflected at a large angle.
The experiment on atoms.Based on historical records and information, Ernest Rutherford performed a set of experiments in 1910 which has helped several scientists and researchers to better understand the structure of atoms by using gold foil.
In his experiment on structure of atoms, Rutherford directed a beam of small, positively charged particles referred to as alpha () particles at a very thin sheet of gold foil.
Basically, the differences which Ernest Rutherford would have observed if he had used aluminum foil instead of gold foil include the following:

Answer: A nuclear power plant produces electricity from a steam-driven turbine. The steam is generated by heat created by Nuclear fission.
Explanation:
A nuclear power plant is a thermal power station with a nuclear reactor as the heat source. Like other thermal power plants, a steam turbine attached to an electricity-generating generator uses heat to create steam.
In contrast, nuclear fission is a reaction in which an atom's nucleus separates into two or smaller nuclei. Large amounts of energy are released in nuclear power plants thanks to the nuclear fission process that takes place there.
Additionally, nuclear fission takes place when neutron particles bombard Uranium-235. The elements in question are uranium-235 and plutonium-239, both of which create high-energy gamma photons as a result of radioactive decay.

The annual inventory cost C for a manufacturer is given below, where Q is the order size when the inventory is replenished. Find the change in annual cost when Q is increased from 340 to 341, and compare this with the instantaneous rate of change when Q = 340. (Round your answer to two decimal places.
The change in annual cost when Q is increased from 340 to 341 is -1.23 and the instantaneous rate of change when Q = 340 is -1.25
How to find the Instantaneous rate of change?The annual inventory cost C for a manufacturer is given as;
C = (1012000/Q) + 7.5Q
where Q is the order size when the inventory is replenished.
Now, the change in C can be calculated by evaluating the cost function at Q = 340 and Q = 341
Change in C = [1,012,000/341 + 7.5*341] - [1,012,000/340 + 7.5*340] ≈ -1.23
Instantaneous rate of change in C is first order derivative C':
