Calculate the electrical energy transferred by a 60W electric bulb that is turned on for 20s and 5minutes.
Answer:
approximately 0.00504 kWh
Explanation:
This electrical energy and is measured in kWh.
For 5 minutes and 20 seconds of use, it is 0.06 W x 0.084 h = 0.00504 kWh.
Note: 60W = 0.06kW; 5min 20sec = 0.083(8) ≈ 0.084 hour

in the accompanying,circuit a battery with an emf of 24 v is connected in series to resistor x and two identical light bulbs connected in parallel.each light bulb is Marked 6 V and 3 w .will the ammeter reading increase or decrease if another identical light bulb is connected in parallel to the existing two and another resistor is connected in series with x? explain your answers
Answer:
Explanation:
When you put another light bulb in parallel with the other two, you are not going to get something for nothing. The current drain on the battery has to go up.
Let the lightbulbs have a a resistance of r. Two light bulbs with make the resistance go to 1/2 r. The lower the resistance, the more the current. When you put the third light bulb in, the resistance will go to 1/3 r. So the current goes up.
If you put another resistor in series with x, the resistance adds. The total series resistance is 2x. The current reading will go down. The higher the resistance the lower the current.

the power of a bulb is 100 watt .what does it mean
Answer:
Explanation: 100 watts is a unit of power.
A watt is also the amount of energy being consumed. So the more watts the brighter the light bulb is lit.

explain why the rest of the group has metallic behavior but boron does not
Answer:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid
Explanation:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals
A student conducts an experiment to determine how the amount of water given to a plant affects its growth.
What is the dependent variable for this experiment?
a. the amount of water
b. the height of the plant
C. the amount of sunlight
d. the amount of soil
Answer:
Option A because the researcher can change the amount of water given to the plant to determine the dependent factor, how much the plant grows. Options C and D are both control variables that need to stay the same in order to perform this experiment correctly.

Answer:
Wanna be my friend?
Explanation:
Who has the greater velocity, an astronaut who has just completed an orbit of the Earth or you when you have just traveled from home to school? Explain.
Answer:
the answer is
Explanation:
constant acceleration
because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration
Acceleration is defined as the rate of change of velocity.
Acceleration = (Change in velocity) / time taken
Acceleration = (Final velocity - initial velocity) / time
As the object velocity changes by the same amount in each second, it means the acceleration is constant.

How are the oscillating magnetic and electric fields of an electromagnetic wave positioned relative to each other?
Answer:
Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.
Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
(A) A few children still use traditional wooden sleds.
(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
(E) Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
Answer:
(E) it seems like the best option
What is concentration gradient?
Answer:
The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.

A student wants to try to convince her parents to stop serving peas for dinner. She lays out her argument that peas are high in fructose, which is a type of sugar. Which test could she use to provide scientific evidence to support her argument that peas are high in fructose?(1 point)
brown paper bag test
vinegar test
Benedict’s test
iodine test
Answer:Benedict’s Test
Explanation:
The student will use Benedict's test to support her argument.
The common reagents for testing carbohydrates are iodine and Benedicts test.
While iodine gives a positive result with starch, it doesn't react with fructose.
Benedict's reagent is used to determine the presence of reducing sugar in a given solution.
A positive test with Benedict's reagent is determined by a color change from clear blue to brick-red with a precipitate.
A reaction between fructose and Benedict's solution gives a positive test from the color change which occurs when the fructose is reduced to simple sugar such as glucose and mannose.
Thus, the student will use Benedict's test to support her argument.

Explain a lever and a pivot in a full sentence
Answer:
The lever is a movable bar that pivots on a fulcrum attached to a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot.
