Barbara plotted an elevation below sea level on a number line and labeled it A. She plotted Point B above 0, a distance that is exactly as far from 0 as Point A is. Explain what you know about Point B.

Answers

Answer 1

Answer:

Point A is the same distance below 0 as Point B is above 0.

Point B is a positive integer.

Since a number and its opposite are the same distance from 0 in opposite directions, Point B is the opposite of Point A.

Explanation:

Answer 2

Answer:

Sample Response: Because Point A is negative and the same distance below 0 on the number line as Point B is above it, Point B is both positive and the opposite of Point A.

A punt is kicked at an angle of 60 with a speed of 40 m/s, and lands at the same
height from which it was kicked.

How far away will the ball land?

What is the maximum height reached by the ball?

What is the hang time? Total

Answers

Answer:

1) The ball will land approximately 141.4 m away from where it was kicked

2) The maximum height reached is approximately 61.22 m

3) The total hang time is approximately 7.07 seconds

Explanation:

First we list out the known parameters

The direction in which the punt is kicked, θ = 60°

The speed with which the punk is kicked, v₀ = 40 m/s

1) The distance away (the range, R) the ball will land is given by the equation;

[tex]R = \dfrac{v_0^2 \times sin(2\cdot \theta)}{g}[/tex]

Where;

g =  The acceleration due to gravity = 9.8 m/s²

Substituting the values, gives;

[tex]R = \dfrac{40^2 \times sin(2\times60^{\circ })}{9.8} \approx 141.4 \ m[/tex]

The distance away the ball will land ≈ 141.4 m

2) The maximum height is given m=by the following equation for vertical motion;

(v₀ × sin(θ))² = 2 × g × [tex]h_{max}[/tex]

Obtained from the equation of motion, v² = u² - 2×g×h where at maximum height;

v = 0 at maximum height, the ball stops upward motion

h = Height of motion = [tex]h_{max}[/tex] at maximum height

v, and u are the vertical component of the velocity, v₀

Substituting the values in the equation for the maximum height, gives;

(40 × sin(60))² = 2 × 9.8 × [tex]h_{max}[/tex]

(40 × (√3)/2)² = 1200 = 19.6 × [tex]h_{max}[/tex]

1200 = 19.6 × [tex]h_{max}[/tex]

[tex]h_{max}[/tex] = 1200/19.6 ≈ 61.22 m

The maximum height reached ≈ 61.22 m

3) The time to maximum height is given by the following equation of motion;

[tex]v_y[/tex] = v₀ × sin(θ) - g × t

[tex]v_y[/tex] = 0 at maximum height

We therefore have;

v₀ × sin(θ) = g × t

t =  v₀ × sin(θ)/g = 40 × sin(60°)/9.8 = (40 ×(√3)/2)/9.8 = 3.535 seconds

Given that the motion of the ball is symmetrical about the maximum height, we have;

The time from ground level to maximum height = The time from the maximum height back to the ground level

The total time hang time = The time from ground level to maximum height + The time from the maximum height back to the ground level

The total time hang time ≈ 3.535 + 3.535 ≈ 7.07 seconds.

The total time hang time ≈ 7.07 seconds.

if a runner is moving 2.88m/s directly north and accelerating at .350 m/s^2 at an angle of -52.0. At the point in the motion where she is running directly east what is the displacement

Answers

Answer:

19.1 m, 52.0°

Explanation:

Given:

v₀ₓ = 0 m/s

v₀ᵧ = 2.88 m/s

vᵧ = 0 m/s

aₓ = 0.350 m/s² cos(-52.0°) ≈ 0.215 m/s²

aᵧ = 0.350 m/s² sin(-52.0°) ≈ -0.276 m/s²

Find: Δx and Δy

First, find time.

vᵧ = aᵧt + v₀ᵧ

0 m/s = (-0.276 m/s²) t + 2.88 m/s

t = 10.4 s

Now find the displacement components Δx and Δy.

Δx = v₀ₓ t + ½ aₓ t²

Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²

Δx = 11.7 m

Δy = v₀ᵧ t + ½ aᵧ t²

Δy = (2.88 m/s) (10.4 s) + ½ (-0.276 m/s²) (10.4 s)²

Δy = 15.0 m

The magnitude of the displacement is:

d² = Δx² + Δy²

d² = (11.7 m)² + (15.0 m)²

d = 19.1 m

The direction of the displacement is:

θ = atan(Δy / Δx)

θ = atan(15.0 m / 11.7 m)

θ = 52.0°

A. 16.5 meters/second B. 20.5 meters/second C. 18 meters/second D. 2 meters/second E. 45 meters/second

Answers

Answer:

Chlorine has 17 electrons. According to the modern atomic theory, how many electrons are found in n = 2?

Answers

Answer:

8 electrons

Explanation:

According to the modern atomic theory, the electronic configuration of chlorine (e⁻ = 17, Z = 17) is:

1 s²             → 2 electrons

2 s² 2 p⁶    → 8 electrons

3 s² 3 p⁵    → 7 electrons  

Total: 17 electrons

In n = 1 chlorine has 2 electrons, in n = 2 chlorine has 8 electrons and in n = 3 it has 7 electrons.

Therefore, in n = 2 chlorine has 8 electrons (2 from s orbital and 6 from p orbital).

How can two different nonmetals form a compound?

Answers

Explanation:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

Nonmetals can form compounds through a process called covalent bonding.

Covalent bonding occurs when two nonmetal atoms share electrons to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outermost energy levels or achieve a noble gas electron configuration.

When two nonmetal atoms come together to form a compound, their electronegativities play a crucial role. Electronegativity is the ability of an atom to attract electrons toward itself in a chemical bond. If the electronegativities of the two nonmetals are similar, they will have a similar tendency to attract electrons, resulting in a more equal sharing of electrons.

So, nonmetals can form compounds through covalent bonding by sharing electrons. The extent of electron sharing depends on the electronegativity difference between the nonmetals involved, leading to either polar covalent or ionic bonding.

Therefore, nonmetals can form compounds through a process called covalent bonding.

Silver has a resistance of 0.0198 ohms. What voltage would produce a current of 250 amps?

Answers

Answer:

V= I x R =250 x 0.0198 = 4.95 Volts

Explanation:

The voltage across the resistor is 4.95 Volts.

How do you calculate the voltage?

Given that the resistance is 0.0198 ohms and the current flowing through the silver is 250 amps.

The voltage V across the resistor is the product of the current I flowing through the resistors and resistance R.

[tex]V = IR[/tex]

Substituting the values, we get the voltage.

[tex]V = 250 \times 0.0198[/tex]

A block of wood has a mass of 8 g and occupies a volume of 10 cm3. What is its density?

Answers

Answer:

0.8 g/cm³

Explanation:

recall that the definition of density is the mass per unit volume of an object.

or mathematically:

density = mass / volume

here we are given that mass = 8 g and volume = 10 cm³

hence,

density = 8 g / 10cm³ = 0.8 g/cm³

The block has a mass of 8 g with a volume of 10 cm³. It density is mass divided by volume that is 0.8 g/cm³.

What is density?

Density of a substance is the measure of  its mass per unit volume. Density is dependent on some other factors beside mass and volume such as bond type, temperature and pressure.

The ratio of density of a substance to the density of water is called its specific gravity. If the substance is denser than water it will sink on water otherwise it will float on it.

The mass of the block of wood = 8 g

volume = 10 cm³

Density = mass / volume

              = 8 g/ 10 cm³

              = 0.8 g/ cm³

Therefore, the density of the wood block is 0.8 g/ cm³.
