Answer:
9.5km/hr and 16.667m/s
Step-by-step explanation:
velocity = Distance / Time
v = 19/2 --> v = 9.5km/hr
v = 2000m/120s --> v = 16.66666667m/s

Which are aspects covered by Bohr’s atomic model?
Electrons can have a measured radius.
Higher orbits have lower energies.
Electrons exist between orbits.
Electrons do not have energy, the energy is determined by the orbit.
The statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.
What is Bohr's atomic model?In the Bohr atomic model, electrons are grouped according to their energy levels. The energy level at which an electron is located determines its energy.
As we know,
The aspects covered by Bohr’s atomic model are:
Electrons can have a measured radius.Electrons do not have energy, the energy is determined by the orbit.Energy is absorbed by electrons as they transition from a lower to a higher energy state. The electron emits energy when it transitions from a higher to a lower energy level. Visible light is one way to view this energy.
Thus, the statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.

Answer: Electrons do not have energy, the energy is determined by the orbit." or A and b
Step-by-step explanation: The correct answer is, "Electrons do not have energy, the energy is determined by the orbit."
In the Bohr model of the atom, electrons are arranged in energy levels. The energy of an electron is determined by the energy level in which it is found.
When electron an the electron moves from a lower to a higher energy level it absorbs energy. When the electron moves from a higher to a lower energy level, it radiates energy. This energy is observed in the form of visible light.
Thus, in the Bohr's model, electrons are arranged in energy levels. The energy level where an electron is found determines its energy.

[tex]\sqrt{x^{2}-16 }-3\sqrt{x-4}=0[/tex]
Answer:
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]
Step-by-step explanation:
[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]
[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]
[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]
[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]
[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]
[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]
[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]
[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]
Answer:
x = 4, 5.
Step-by-step explanation:
√(x^2 - 16) - 3√(x - 4) = 0
√(x^2 - 16) = 3√(x - 4)
Square both sides of the equation:
x^2 - 16 = 9(x - 4)
x^2 - 9x - 16 + 36 = 0
x^2 - 9x + 20 = 0
(x - 4)(x - 5) = 0
x = 4, 5.
As the original equation contained square roots:
We test for extraneous solutions:
x = 4:
√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0 so x = 4 is OK.
x = 5:
√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0 so x = 5 is also OK.

4/s-3 + s/2 = -2
Need help please
Step-by-step explanation:
Given equation is 4/(s-3) + (s/2) = -2
=> [(4×2)+s(s-3)]/2(s-3) = -2
=> (8+s²-3s)/(2s-6) = -2
=> 8+s²-3s = -2(2s-6)
=> 8+s²-3s = -4s+12
=> s²-3s+8+4s-12 = 0
=> s²+s-4 = 0
The standard form is s²+s-4 = 0
Reflect the image over the y-axis and then translate 8 units down. What are the coordinates for C’?
Answer:
(-7, -7)
Step-by-step explanation:
1. Let's ONLY focus on point C.
2. The algebraic rule for reflecting across the y-axis is (x, y) -> (-x, y).
Since point C is on the coordinate (7,1), when reflecting it across the y-axis, it's going to turn into (-7,1).3. The algebraic rule for translating 8 units down is (x, y) -> (x, y - 8).
Since C is on (-7,1), when we translate it 8 units down, we'll get C' as (-7, -7)Therefore, the coordinates for C' are (-7, -7).

50% more than what number is 20% less than 60% more than 10?
Answer:
Step-by-step explanation:
Let's start by decoding this :)
First lets do 60% more than 10; 16 (mental math)
Next, lets do 20% less than 16; x/16 = 80/100 (Equation)
After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.
rewrite the equation in standard form y - 6 = -1/2 (x-5)
Standard Form: Ax + By = C
---A cannot be negative, nor can it be a decimal or fraction
y - 6 = -1/2(x - 5)
Distribute the -1/2
y - 6 = -1/2x + 5/2
Add -1/2x to both sides
1/2x + y - 6 = 5/2
Add 6 to both sides
1/2x + y = 17/2
Multiply everything by 2 to get rid of the fractions
x + 2y = 17

Answer:
y=2x+1, assuming my change in the reported data was correct.
Step-by-step explanation:
The data for x had one more entry than the values for y. I removed the second "0" so that the x and y points line up, as shown in the attached image. The data indicate a straight line, with a slope of 2 (y increases by 2 for every x increase of 1). The y-intercept is 1, as per the first data point (0,1).
