Describe two possibilities of what will happen to the universe in the future.
The Universe in the future have two possibilities:
The Universe will come to an end in the opposite of a Big Bang called The Big Crunch. The other possibility is that we live in an Eternal Universe that will never come to end.What is universe?Universe is the whole cosmic system of matter and energy. The Earth, the Sun, the Moon, the planets, the stars along with the dust , gases, rocks forms the universe.
The big bang is the theory which explains that how the universe began. It says that the universe began with just a single point. It went on expanding and stretched to grow as large as possible. It is still now expanding.
The universe consist of fully dark matter, interstellar gases or dust. The big bang is increasing just because in universe there is abundant of hydrogen and helium. The two possibilities:
The Universe will come to an end in the opposite of a Big Bang.The other possibility is that we live in an Eternal Universe that will never come to end.This universe is still on it way of expanding more.

Which group number below represents the Oxygen Group?
1 point
18
Periodic Table of the Elements
14
15
2
18
16
Oxygen has an atomic number 8, because it has 8 protons and 8 electrons.
The first shell of an atom can hold up to 2 electrons but oxygen has 8 electrons, in that eight electrons 2 are in the first shell, so it has 6 more electrons left. The second shell can hold up to 8 electrons, oxygen has only 6 more electrons after the first shell is full, so it will have 6 electrons in the second shell
From this we know that oxygen has 2 shells so it is in period 2, and by counting from left to right, the sixth box in period 2 lies on group 16
Therefore Oxygen lies on group 16 and period 2

A 10 ohms resistor, 10 mh inductor, and 10micro farad capacitor are connected in series with a 10khz voltage source. The rms current through the circuit is 0.20A. Find the rms voltage drop across each of the three elements
Answer:
126 V
Explanation:
The computation of the rms voltage is shown below:
= I × R
=(.2) × (10)
= 2 V voltage drop across capacitor
= I × 1 ÷ (?C)
= I ÷ (2 × pi × f × C)
= (.2) ÷ (2 × pi × 10,000 × 10 × 10^-6)
= .318 V voltage drop across inductor
= I × ?L
= I × 2 × pi × f × L
= .2 × 2 × pi × 10,000 × .010
= 126 V

When an object is moving to the left and slowing down, what direction is the acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.
Explanation:
In which of the following is a skater NOT accelerating?
A-going straight while speeding up
B-going straight at constant speed
C-making circles at constant speed
D-going straight while slowing down
The height of a helicopter above the ground is given by h = 3.0 t^2, where h is in meters and t is in seconds. After 5.0 s, the helicopter releases a small mailbag. How long after its release does the mailbag Preach the ground
Answer:
3.91 s
Explanation:
From the question,
The height of the helicopter is given as
h = 3t²......................... Equation 1
After 5 seconds, The height of the helicopter is given as
h = 3(5²)
h = 3×25
h = 75 m.
Note: The small mailbag falls under gravity.
Hence,
h = ut + 1/2(gt²)....................... Equation 2
Where u = initial velocity of the mailbag, t = time, h = height, g = acceleration due to gravity of the mail bag.
Given: h = 75 m, u = 0 m/s ( at the maximum height).
Constant: g = 9.8 m/s²
Substitute these values into equation 2
75 = 0(t) +1/2(9.8t²)
solve for t
1/2(9.8t²) = 75
4.9t² = 75
t² = 75/4.9
t² = 15.31
t = [tex]\sqrt{15.31}[/tex]
t = 3.91 s

The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Show how to use geometry and the Pythagorean Theorem to calculate the total relative motion toward the northwest.
Answer:
7 mm per year
Explanation:
It is given that :
The Pacific plate is moving towards north at = 29 mm per year
The Pacific plate is moving towards west at = 20 mm per year
We have to calculate the total relative motion towards the northwest.
So we have to find the resultant of the two motions.
Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.
Therefore, finding their resultant,
[tex]R^2=(29)^2+(20)^2[/tex]
[tex]R^2=(49)^2[/tex]
R = 7
Therefore, total relative motion towards the northwest is 7 mm per year.

Hot air balloons use a flame that can turn on and off to heat air inside a large balloon. The balloon is attached to a basket which can carry people or cargo as it is lifted off the ground and floats in the air.
Using what you know about gases, predict which approach would allow the hot air balloon to reach the highest height?
A.
Turn on the flame for 10 seconds each minute for 10 minutes to increase the density of the air inside the balloon.
B.
Turn on the flame for 10 seconds each minute for 2 minutes, and cut a large hole in the balloon material to allow excess air out.
C.
Turn on the flame for 30 seconds each minute for 2 minutes, and cut a large hole in the balloon material to allow excess air out.
D.
Turn on the flame for 30 seconds each minute for 10 minutes to decrease the density of the air inside the balloon.
Answer:
The answer is B. :)
Explanation:
The hot air balloon reaches the highest height turn on the flame for 10 seconds each minute for 2 minutes and cut a large hole in the balloon material to allow excess air out.
What is a hot air balloon?Because hot air rises, hot air balloons work. By using the burner to heat the air inside the balloon, it becomes lighter than the cooler air on the outside.
As a result, the balloon floats upwards, as if it were in the water. Obviously, allowing the air to cool causes the balloon to slowly deflate.

1. In a demonstration, Mr. K stretches a steel wire to a length 1.23 meters and braces both ends so that they are not free to vibrate. He attaches a fancy piece of equipment which he calls a mechanical oscillator to the wire and explains how it works. Then Mr. K turns the oscillator on and tunes the frequency to 588 Hz. To the amazement of the class, the wire begins vibrating in the sixth harmonic wave pattern. a. Determine the speed of waves within the wire. b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern. c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
Answer:
a.241.08 m/s b. 196 Hz c. 392 Hz
Explanation:
a. Determine the speed of waves within the wire.
The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.
Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have
v = 2Lf/n
substituting the values of the variables into v. we have
v = 2 × 1.23 m × 588Hz/6
v = 241.08 m/s
b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.
The first harmonic is obtained from f when n = 1,
So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz
c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz

An object falls from a height of 12m. The object's potential energy at the top is 50J. Where is the potential energy of the object
25J
Answer:
the height of the is 6 m.
Explanation:
Given;
potential energy of the object, P.E = 50 J
Height of fall of the object, H = 12 m
Determine the mass of the object, m
P.E = mgh
m = (P.E) / (gh)
m = (50) / (9.8 x 12)
m = 0.425 kg
Let the height of the object at 25 J = h₂
mgh₂ = 25
h₂ = (25) / (mg)
h₂ = (25) / (0.425 x 9.8)
h₂ = 6 m
Therefore, the height of the object at 25 J is 6 m.
2. A 4.0 kg magnetic toy car traveling at 3.0 m/s east collides and sticks to a 5.0 kg toy magnetic car also traveling at 2.0 m/s east. Calculate the final speed and direction of the magnetic car (coupled) system?
Answer:
2.44 m/s due East
Explanation:
From the question given above, the following data were obtained:
Mass of 1st car (m₁) = 4 Kg
Velocity of 1st car (u₁) = 3 m/s
Mass of 2nd car (m₂) = 5 Kg
Velocity of 2nd car (u₂) = 2 m/s
Final velocity (v) =?
The final velocity can be obtained as follow:
v(m₁ + m₂) = m₁u₁ + m₂u₂
v(4 + 5) = (4×3) + (5×2)
9v = 12 + 10
9v = 22
Divide both side by 9
v = 22/9
v = 2.44 m/s
Thus, the final velocity is 2.44 m/s.
Since both cars was moving due East before collision, and after collision, they stick together, then their direction will be due East.
