The kilowatt-hours consumed by an 850-watt window air conditioner turned on for four hours is 3.4 kw-h
Power is defined as the rate of work over a time period. Mathematically,
P = W/t
Where:
P = power
W = work done
t = time period
The unit of power is Watt which is equivalent to Joule/second. Another widely used unit is kw=h or kilowatt-hours.
Information available in the problem:
P = 850 Watt = 0.85 kw
t = 4 hours
Plug these parameters into the formula:

The correct answer is both are correct technician a says the vat contains a carbon pile that is a variable resistor. technician b says the vat is used to check batteries, starting systems, and charging systems.
A resistor is an electrical component that controls or restricts how much electrical current may pass across a circuit in an electronic device. A specified voltage can be supplied via resistors to an active device like a transistor. Modern resistors are often constructed from a carbon, metal, or metal-oxide layer. In these resistors, an insulating material is wrapped in a helix around a thin film of conductive (but still resistant) material.A passive electrical component called a resistor prevents the flow of electric current by introducing resistance. They are present in practically all electrical networks and electronic circuits. Ohms () are used to measure resistance.

A tetherball leans against the smooth, frictionless post to which it is attached. The string is attached to the ball such that a line along the string passes through the center of the ball. The string is 1.30 m long and the ball has a radius of 0.160 m with mass 0.470 kg.
Part A: What is the tension in the rope?
Part B: What is the force the pole exerts on the ball?
Problem 2. An 88 N box of oranges is being pushed across a horizontal floor. As it moves, it is slowing at a constant rate of 0.90 m/s each second. The push force has a horizontal component of 20 N and a vertical component of 25 N downward.
Calculate the coefficient of kinetic friction between the box and floor. Express your answer using two significant figures.
The tension in the rope is 4.59 N. The box's kinetic friction coefficient with the floor is 0.23.
How to Calculate tension and force?Problem 1: To calculate the tension in the rope, we need to calculate the weight of the ball,
which can be done using the formula F = mg,
where F is the force (weight) of the ball, m is the mass of the ball, and g is the acceleration due to gravity (9.81 m/s^2).
Therefore,
the weight of the ball is 0.470 kg * 9.81 m/s^2 = 4.59 N.
Since the tension in the rope is equal to the weight of the ball, the tension in the rope is 4.59 N.
Since the post is frictionless, the pole exerts no force on the ball.
Problem 2: To calculate the coefficient of kinetic friction,
we need to use the formula μk = Ff/Fn,
where "μk" stands for "kinetic friction coefficient,"
Ff is the frictional force, and Fn is the normal force.
Since the push force has a horizontal component of 20 N and a vertical component of 25 N downward,
the normal force is 25 N.
Since the box is slowing at a constant rate of 0.90 m/s each second,
The frictional force can be found using the formula Ff = ma
The box's kinetic friction coefficient with the floor is 0.23.

If you double your speed how much will that increase your braking distance?
For instance, the thinking distance will increase from 9 m to 18 m and the braking distance will grow by a factor of four from 14 m to 56 m if a car's speed is doubled from 30 mph to 60 mph.
The distance that a car travels while braking completely is known as the braking distance. A number of factors affect the braking distance. First, the braking distance will be impacted by the grade (slope) of the road. Gravity helps you stop more easily and shortens the stopping distance when you are moving uphill. Similar to how it works against you as you drop, gravity will lengthen your braking distance. Next, your braking distance may be impacted by the frictional resistance between the road and your tires. On a wet road, it's likely that you'll need greater stopping distance than you would on a dry road if you have old tires. Your beginning velocity will be the final factor we take into account.

given 5 rocks of different weight and lever scales, in 7 tests sort the rocks by weight. show that for all outcomes of comparisons you will find the correct order by the 7th comparison.
A balance puzzle, sometimes known as a weighing puzzle, involves using balance scales to weigh objects.
Problem with level of weight and rocks?
We begin by comparing A>B and C>D. The two heavier ones are measured next, and we find that A>C. This handily reduces our options for the stones A, B, C, and D to just three. Specifically, ABCD, ACBD, and ACDB Notably, stone C is positioned perfectly in the centre, either as number 2 or number 3. As a result, we compare stone E to stone C. If E turns out to be heavier than A, we compare it against A. We compare it to stone D to see if E is lighter.
What is the absolute minimum to find the heavier rock?
Label the nine rocks as A, B, C, D, E, F, G, H and I
Put them in groups of ABC, (1)DEF, (2), and GHI.
(3) Place the rocks from group (1) in one pan and those from group (2) in the other pan. If they are of same weight, then neither group (1) nor group (2) of rocks contain the slightly heavier rock.
Rock G should now go in one pan and Rock H should go in the other. If they both weigh the same, the heavier rock is I.
If rock G is heavier than rock H when they are placed in separate pans, then G will be the heavier.

How convert numbers into java programming?In Java, you can convert numbers into various types such as int, float, double, etc. using the built-in type conversion functions. For example, to convert an int to a float, you can use the Float.parseFloat(String s) function.
This function takes in a string representation of the number, and returns a float. Similarly, you can use Integer.parseInt(String s) to convert a string to an int.
There are also other type conversion functions available such as Long.parseLong(String s) and Double.parseDouble(String s). Additionally, you can use the wrapper classes such as Integer,
Float, and Double to convert numbers from one type to another. For example, if you have an int variable and you want to convert it to a double, you could use the Double wrapper class to do so. Finally, you can also use the toString() method on any type to convert it to a string.

A reliable alternator should keep the battery voltage constant at 13.9 to 14.8 volts.
What is alternator voltage?When the automobile is moving, the alternator powers the interior electrical and electronic equipment while simultaneously charging the battery. They are typically operated at a voltage between 13 and 14. The battery voltage should remain consistent at 13.9 to 14.8 volts with a dependable alternator (14.2 is optimum).Modern cars employ a direct electric current supply for the ignition, lighting, fans, and other functions. Electricity is generated by an alternator that is mechanically attached to the engine.It has a three-phase winding in the stator and a rotor field coil that receives current through slip rings.A generator of electricity known as an alternator transforms mechanical energy into alternating current. The majority of alternators utilise a revolving magnetic field with a stationary armature for economical and practical reasons.To learn more about alternator voltage, refer to:

The maximum shear stress equals the difference between the primary stresses divided by 0.5.
The basic planes equation, 2p, yields two angles between 0° and 360°, as is to be noted.
In accordance with this idea, yielding is projected to occur in triaxial states of stress whenever the yield stress is equal to half the algebraic difference between the greatest and lowest stress.
For a triaxial situation of stress where 1 > 2 > 3, the maximum shear stress is consequently (1 > 3)/2.
