Within a period of the periodic table, how do the properties of the elements vary?

Physics
1 answer:
Nonamiya [84]3 years ago
5 0

Answer:

Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

Explanation:

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. ... They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.

A machine does 1500 joules of work in 30 second What is the power of the machine
lesya [120]
This is simple as power in watts is equal to joules per second so we can do 1500 joules divided by 30 seconds which equals 50 watts

Does anyone know the answer to this?
sweet-ann [11.9K]
Disclaimer: I just answered this, here is the answer again!
*Used copy paste from my own answer as it is a repeated question, no copied work*

3. A
The relation between V and I at constant R is;V=IR, so it is a direct linear relation.
4. A
This is another direct linear relation as P=IV.
5. D
The relation between P, R, and V is P=, so P is inversely proportional to R.
6.B
The relation between P,I, and R is , so P is directly proportional to the square of I.

Please note that y:x relations are always straight lines while  relations are parabolic lines.

Hope this helps!

Care din propozitiile de mai jos sunt propozitii simple si care sunt propozitii dezvoltate? Argumentati oral raspunsurile a) mâț
Nataliya [291]

Answer:

a) developed

b) simple

c) simple

d) developed

e) developed

f) developed

Question:

Which of the following sentences are simple sentences and which are developed sentences? Orally argue the answers

a) the cat scribbled the little girl.

b) Grandma will cook

c) The cat will spin

d) You don't love cats?

e) in one jump, the cat will be at the window

f) we will never arrived on time

Explanation:

To differentiate the simple sentences from the developed sentences, let's understand what they are.

A Simple sentence is a sentence that contain a subject and a predicate. The sentence is complete in thought.

A developed sentence is a sentence that contain a subject, predicate as well as other parts of sentence.

a) the cat scribbled the little girl (developed)

b) Grandma will cook (simple)

c) The cat will spin (simple)

d) You don't love cats? (developed)

e) in one jump, the cat will be at the window (developed)

f) we will never arrived on time (developed)

Hence option b and c are simple sentences, while options a, d, e and f are developed.

Can someone pls help ! I’m sorry it’s small
solmaris [256]

Answer:

The velocity time graph which shows a negative constant velocity (horizontal line below the horizontal axis) Labeled as Graph #2

Explanation:

Notice that the position-time graph shows the position decreasing in the form of a line with negative slope. Recall that the velocity graph is associated with the change in position with time, and this change in position is in the form of a line of constant negative slope. The slope of the position-time graph is in fact the velocity of the object, which therefore is negative and constant.

Such behavior is represented by the graph labeled as Graph 2 of a constant (horizontal) line below the horizontal axis.
