Each atom within a specific element has the same number of neutrons, which determines its atomic number.

Reword the statement so it is true.

Answers

Answer:

Each atom within a specific element has the same number of protons, which determines its atomic number.

Protons determine an atoms atomic number

Ex:
Carbons atomic number: 6
Carbons number of protons: 6

Oxygens atomic number: 8
Oxygens number of protons: 8

Each atom within a specific element has the same number of protons, which determines its atomic number. The correct statement.

This is inaccurate because the atomic number of an element is determined by the number of protons in the nucleus of its atoms, not by the number of neutrons.

Each atom within a specific element has the same number of protons, which determines its atomic number. The atomic number of an element is a fundamental property that defines the element and its place on the periodic table.

The number of protons in the nucleus of an atom of that element. Neutrons, do affect the atom's mass and stability but do not determine their atomic number.

The correct statement is Each atom within a specific element has the same number of protons, which determines its atomic number.

If the density of a liquid is 20gcm - 3 height is 4cm and gravitational field strength is 10 N kg, the pressure of the liquid is ​

Answers

Answer:

Pressure is 1.96 × 10^12 Pa

Explanation:

[tex]{ \bf{pressure = \frac{force}{area} }}[/tex]

height = 4 cm = 0.04 m

density = 20 g/cm³ = 20,000 kg/m³

But for force:

[tex]{ \sf{force = mass \times acceleration}} \\ { \sf{force = ( \frac{density}{volume} ) \times acceleration}} \\ \\ { \sf{force = ( \frac{20000 }{0.04 {}^{3} }) \times 10 }} \\ \\ { \sf{force = 3.13 \times {10}^{9} \: newtons}}[/tex]

For area:

[tex]{ \sf{area = 0.04 \times 0.04 = 0.0016 \: m {}^{2} }}[/tex]

[tex] { \tt{pressure = \frac{3.13 \times {10}^{9} }{0.0016} }} \\ \\ = { \tt{1.96 \times {10}^{12} \: pascals}}[/tex]

A stone is dropped from the top of the tower at height h. After 1 second another stone is dropped from balcony 20m below the top.Both reach ground at same time. What us the value of h.

Answers

In case of stone s = h meter, u = 0m/s t = t sec and a = g (acceleration due to gravity = 10m/s2). Now a second stone drops after 1 sec from the balcony 20 m below the top and it reaches the bottom at the same time. So the height of the balcony from the ground = (h – 20) m.

difference between:
1.distance and displacement
2.centripetal froce and centrifugal force
3.speed and velocity
4.velocity and acceleration​

Answers

Explanation:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.Centripetal force is the force REQUIRED for circular motion. Centrifugal force is the force that makes something flee from the center.Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity.

When is the pressure of the man on the ground more – lying position or standing
position? Explain.

Answers

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

An element has six valence electrons. Which ionic charge will its ion carry?(1 point)

2–

2+

6+

6–

Answers

Answer:

It's 2–

Explanation:

Usually, in ionic bonds, these elements will receive 2 electrons, so its ion will carry a 2– charge

The ionic charge its ion will carry will be 2-

An element is required to have 8 electrons in its outermost shell to assume it's full octet configuration.

The statement above of course excludes Hydrogen and helium which have only 1 and 2 electrons respectively.

An element with 6 Valence electrons would require 2 electrons to assume the full octet configuration.

As such, it is liable to accept 2 electrons from an electropositive element or group of elements to complete it's octet.

Therefore, accepting 2 electrons adds 2 negative charges and consequently, the ionic form of the element carries a 2- ionic charge

Part 1)

Force = Mass x Acceleration

Divide both sides by acceleration

force / acceleration = mass

mass = force / acceleration

Part 2)

Divide both sides by mass

force / mass = acceleration

acceleration = force / mass

How far will a car move if it starts from rest, reaches a final speed of 40 m/s, and accelerated at 2 m/s/s?

Answers

Answer:

800 m

Explanation:

Acceleration (a) = Velocity (v) / Time(t)

a = (v-u) /t

where, v = final speed

u = initial speed

2m/s² = (40m/s - 0m/s)/t

that is, from rest is no speed.

2m/s² = (40m/s) /t

t = (40m/s)/2m/s²

t = 20 s

hence, the car has accelerated for 20 s.

From,

Velocity (v) = Displacement (d) /time(t)

displacement is the distance the car has travelled.

40m/s = d/20s

d = 40m/s × 20s

d = 800 m
