An Alaskan rescue plane traveling 46 m/s drops a package of emergency rations from a height of 101 m to a stranded party of explorers. The acceleration of gravity is 9.8 m/s^2. Where does the package strike the ground relative to the point directly below where it was released? Answer in units of m.
Answer:
The package strikes 207 m at the ground relative to the point.
Explanation:
Given that,
Speed = 46 m/s
Height = 101 m
Acceleration = 9.8 m/s²
We need to calculate the time
Using equation of motion
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
Put the value in the equation
[tex]101=0+\dfrac{1}{2}\times9.8\times t^2[/tex]
[tex]t=\sqrt{\dfrac{2\times101}{9.8}}[/tex]
[tex]t=4.5\ sec[/tex]
We need to calculate the distance where the package strikes
Using formula of distance
[tex]x=vt[/tex]
Put the value into the formula
[tex]x=46\times4.5[/tex]
[tex]x=207\ m[/tex]
Hence, The package strikes 207 m at the ground relative to the point.

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
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.

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

A model rocket is launched from the ground. It starts from rest and accelerates upward at 15.0 m/s2 for 3.00 s. Disregard gravity. What is the V2? b. Then, it has a downward acceleration of -10.0 m/s2 until it reaches its highest point. What is the highest above the ground that the rocket gets? c. What is the TOTAL time in the air?
Answer:
The final velocity v₂ is 45 m/s
The highest point reached by the rocket is 101.25 m
The total time spent in air by the rocket is 7.5 s
Explanation:
Given;
initial velocity of the rocket, v₁ = 0
final velocity of the rocket, v₂ = ?
upward acceleration of the rocket, a = 15 m/s²
time of acceleration, t = 3 s
The final velocity is given by;
v₂ = v₁ + at
v₂ = 0 + (15 x 3)
v₂ = 45 m/s
The highest point reached by the rocket is given by;
v² = u² + 2ah
where;
u is the initial velocity of rocket when it started decelerating.
thus, u = v₂
v is the final velocity of the rocket at its highest point = 0
0 = v₂² + 2ah
0 = (45)² + (2 x -10 )h
0 = 2025 - 20h
20h = 2025
h = 2025 / 20
h = 101.25 m
Time taken for the rocket to reach its highest point is given by;
h = ut + ¹/₂at²
101.25 = 45t + ¹/₂(-10)t²
101.25 = 45t - 5t²
5t² - 45t + 101.25 = 0
t² - 9t + 20.25 = 0
t = 4.5 s
The total time spent in air by the rocket is given by;
T = upward time + downward time
T = 3 s + 4.5 s
T = 7.5 s
A boat is headed with a velocity of 18 meters/second toward the west with respect to the water in a river. If the river is flowing with a velocity of 2.5 meters/second in the same direction as the boat. What would be the magnitude of the boat’s velocity? A. 16.5 meters/second B. 20.5 meters/second C. 18 meters/second D. 2 meters/second E. 45 meters/second
Answer:
20.5
Explanation:
in this case, the two vectors are in the same direction, so they simply add:
total motion = 18m/s + 2.5m/s = 20.5m/s to the west

How can two different nonmetals form a compound?
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.

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