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
Between which types of elements do ionic bonds occur, and how do electrons act within the bond?(1 point)
nonmetals and nonmetals, electrons shared
metals and nonmetals, electrons transferred
metals and metals, electrons freely moving
nonmetals and metals, electrons shared
Answer:
Im pretty sure that its, the metals and nonmetals, electrons transferred.
Between metals and nonmetals, types of elements do ionic bonds occur, and electrons transferred within the bond,therefore the correct answer is option B.
What is an ionic bond?When two similar or dissimilar atoms form bonds with each other by transferring their valence electron the bond is known as the ionic bond.
The ionic bond is the result of the transfer of the electrons
Ionic bonds are formed between the pair of one electronegative atom and an electropositive atom.
Ionic, covalent, and hydrogen bonds are the three basic types of chemical bonds that are used to generate these chemical compounds from their component atoms.
Ionic bonds are created when electrons are transferred between two bond-forming pairs that can be distinguished by their electronegativity.
Thus, Between metals and nonmetals, types of elements do ionic bonds occur, and electrons are transferred within the bond, therefore the correct answer is option B

If a body is dropped from the same height once in the equator and then in polar region in which place will it fall faster? why
Explanation:
equator.
because the "belly" of the Earth around the equator makes the Earth there thicker than from pole to pole.
the reason is the spinning of our planet. as the spinning speed is the fastest at the thickest part of a ball (at the equator), that ball has the tendency due to the centrifugal force to extend even further there, and the extra material for that is being pulled in from the poles.
therefore, the diameter through the Earth from equator to equator is larger than the diameter from pole to pole.
and that means that there is more mass from equator to equator than from pole to pole.
and that means that gravity is stronger at the equator.
therefore, a body will fall faster at the equator than on a pole.

A tall tree has more chance to break during storm why
Answer:
yes
Explanation:
because the strong winds and the weight and there are more things to break
Explanation:
A tall tree may have more resistance to the wind since it has more mass ( branches, leaves). That means the wind has more mass to push against. Winds may also be stronger at a higher level. Tall trees have been growing longer and have more chances to have been compromised by insects, animals, fungi and so on. They also have less flexibility since they need to be more rigid to hold up the mass of branches they have.

what is the acceleration of a car that goes from 4m/s to 8m/s in 2s use the guess method
Answer:
12m/3s is the answer I hope its right...Please help me, I really need someone
Answer:
In plotting position versus time it can be seen that the green line represents a fixed position at the various times given - the other lines represent changing position with time
The (horizontal) green line describes an object that's not moving.
Whatever TIME you pick to look at the green line, its POSITION is always the same. This is a pretty good description of "not moving".
The other three lines all have different positions at different times, so they all describe motion.
A stone of mass 600g is thrown vertically upwards. calculate the value of the gravitational force on the stone at its highest point. take g = 10N/kg
Answer:
6N
Explanation:
F = m × g
= 0.6 × 10
= 6N
to find the force you first have to convert the mass to kg by dividing 600 by 1000 giving you 0.6
then you can multiply the mass times the gravity giving you a gravitational force of 6N

1. Alice decides to measure the density of the banana.
a)What equipment will she need to measure it?
b)Explain how she could use that equipment to measure the density.
Answer:
A) Measuring cup with water and a scale
Explanation:
Fill the measuring cup with water to a certain point, and record the current height of the water. After placing the banana fully into the water, record the new height of the water. Subtract the old height from the new height. Now you have the banana's volume.
Then, place the banana on a scale to get it's mass.

In the periodic table, we have an arrangement of atoms based on their respective groups and periods.
If I pick two representative elements in the same period, their number of valence electrons will differ by 1 but they will all be accommodated in the same energy level.
Helium is the first member of group 18. Unlike the other members of the group, its first shell is also its valence shell. It has two and not eight valence electrons like other members of the group.
The electronic configuration of Ca is [Ar] 4s², that of Li is [He] 2s1, that of Cs is [Xe] 6s1, that of Br is [Ar] 4s² 3d¹⁰ 4p⁵ and that of oxygen is [He] 2s² 2p⁴.
We can see that only Cs has valence electrons in higher energy orbitals than those of Ca.

A mother finds her daughter’s mug of hot cocoa on a table an hour after she had been drinking it. As the mother pours out the cocoa, she sees brown solids in the bottom of the mug. How can this be explained?(1 point)
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.
All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug.
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.
This would only happen if too much cocoa powder was added in the first place, because the solubility should not change.

Fluorescent lamp of 25W gives more light than the filament lamp of 50W. Why?
Answer:
Fluorescent lamp releases more light energy.
Explanation:
This is so because the fluorescent lamp releases more light energy and less heat energy than that of a filament lamp with the same rating.
Fluorescent lamp releases more light energy than that of filament lamp and also less heat energy than that of a filament lamp.
What is Power of fluorescent lamp and filament lamp?The filament and the fluorescent lamps are two different types of most commonly used light lamps. The filament lamps are the lamps which work on the phenomenon of incandescent whereas a high resistance filament is heated up in the lamp until it radiates visible light energy. Whereas, a fluorescent lamp is the lamp which works by ionizing a gas that emits photons or energy particles.
The fluorescent lamp releases more light energy and less heat energy than that of a typical filament lamp with the less power of 25W than 50W.

show with the help of an experiment that the acceleration of a freely falling body doesn't depend on the mass of that body. pls answer this question:)
Answer:
Experiment
Materials needed
Stop watch, a small stone, a big stone, a balance.
Procedure
Measure the mass of the two stones.
Hold the two stones about 5m above the ground level.
Drop the stones simultaneously.
Record the time taken for the stones to strike the ground.
Repeat the procedure with different masses of objects at the same height.
Observation, it will be observed that, all the objects dropped from the same height strike the ground at the same time interval.
Conclusion; a falling object doesn't depend on mass
Explanation:
½mv²=mgh
g=½(V²/h)
When an object is held at a height, it posses gravitational potential energy which is mgh, where m= mass, h=height, g=acceleration due gravity
When the object is dropped, the potential energy will be converted to kinetic energy which is ½mv², where V=velocity at which the object moves.
V=∆h/t, ∆h is change in height with respect to time.
½mv²=mgh
Mass cancel out,
g=v²/2h
This implies that g does not depend or is not affected by mass. Hence heavy object and light object will reach the ground at the same time when dropped from the same height. When air resistance is negligible.
