On your first trip to Planet X you happen to take along a 100 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 22.6 cm . You then pull the mass down 10.9 cm and release it. With the stopwatch you find that 10 oscillations take 18.8 s .
Answer:
[tex]g=2.513m/s^2[/tex]
Explanation:
From the question we are told that:
Mass Taken [tex]m=100g \approx 100*10^{-3}[/tex]
Strain on Spring [tex]l_s=22.6cm \approx 22.6*10^{2}[/tex]
Distance pulled down [tex]d_d=10.9[/tex]
Time for ten oscillations take [tex]t=18.8s[/tex]
Generally the equation for angular velocity is mathematically given by
[tex]\omega=2\pi\\\omega=2\pi*\frac{10\ oscillations}{t}\\\\\omega=2\pif=2\pi*\frac{10\ oscillations}{18.8}\\Also\\\omega=\sqrt{\frac{k}{m}} \\\omega=\sqrt{\frac{k}{100*10^{-3}}}[/tex]
Therefore
[tex]{2\pi*\frac{10\ oscillations}{18.8}}=\sqrt{\frac{k}{100*10^{-3}}} \\k=\sqrt{2\pi*\frac{10\ oscillations}{18.8}}*100*10^{-3}\\k=1.112N/m[/tex]
Generally the equation for Acceleration due to gravity is mathematically given by
[tex]F=mg\\mg=k l_s\\g=\frac{k l_s}{m}\\g=\frac{1.112*2.6*10^{2}}{100*10^{-3}}[/tex]
[tex]g=2.513m/s^2[/tex]

What is the difference in intensity for two sounds that are 40 dB apart?
the difference of 10 dB is considered as having 10 times the intensity, so difference of 40 dB means :
=》10 × 10 × 10 × 10
=》10000 times
so the the intensity of one sound is 10000 times the other one.

If a document is to be produced using a duplicating
camera, where should the camera be placed in or
der to obtain an exact copy? A. at the point which
is twice the focal lenght of the lens of the camera
B. at the optical centre of the lens of the camera C
between the principal and a point twice the foca
lens of the lens of the camera D. beyond a poin
twice the focal lenght of the lens of the camera
Answer: A. at the point which
is twice the focal lenght of the lens of the camera
Explanation:
When a certain document is to be produced through the use of a duplicating camera, it should be noted that the camera should be placed at the point which is twice the focal lenght of the lens of the camera so as to get the exact copy of the document.
It should be noted that placing the camera between the principal and a point twice the focal lens of the camera lens or beyond a point that's twice the focal length will not produce the document.
Therefore, the correct option is A

The total resistance of the circuit for parallel resistors of 41 Ω and 17 Ω is 12Ω. Hence option D is correct.
What is a parallel and series combination of resistance?When two or more resistors are connected between two same points, they are said to be connected in parallel combination(as shown in fig). The equivalent resistance is the reciprocal and the sum of reciprocals of all resistance connected in parallel combination.
[tex]\frac{1}{R_{s}} = \frac{1}{R_{1}} + \frac{1}{R_{2} } + \frac{1}{R_{3}} ..........+ \frac{1}{R_{n} }[/tex] where Rs is the equivalent or total resistance of the circuit.
In parallel combination, same potential difference exists across each resistor. But current through each resistance is different.
When two or more resistors are connected one after other, they are said to be connected in series as shown in figure. in this combination voltage difference across each resistance is different which is given by ohms law. current flowing through each resistance is same.
equivalent resistance for series combination is given by,
R(s) = R₁ + R₂ + R₃...........+R(n).
In this problem given resistance are not seen, Resistor can be with 41 and 17Ω.
Given,
R₁ = 17 Ω
R₂ = 41 Ω
[tex]R_{s} = ?[/tex]
by parallel combination,
[tex]\frac{1}{R_{s}} = \frac{1}{R_{1} } + \frac{1}{R_{2} }[/tex]
[tex]R_{s} = \frac{R_{1} R_{2} }{R_{1} + R_{2} }= \frac{17*41}{17+41} = \frac{697}{58} = 12[/tex]
R = 12 Ω.
Hence option D is correct.

A fall thrown vertically upwards with a speed
of 20 ms-¹ from the top of a tower reaches
the earth in 8seconds. find the height of the
tower.
take g= 10ms-²
Answer:
Height of tower = 480 meter
Explanation:
Given:
Initial velocity = 20 m/s
Time taken to reach ground = 8 second
So,
Final velocity = 0 m/s
Acceleration due to gravity = 10 m/s²
Find:
Height of tower
Computation:
s = ut + (1/2)(g)(t)²
s = (20)(8) + (1/2)(10)(8)²
s = 160 + (1/2)(10)(64)
s = 160 + (10)(32)
s = 160 + 320
s = 480 meter
Height of tower = 480 meter

Answer:
Part A
The sound intensity at the location 150 from the firework = 4.3[tex]\overline 5[/tex] W/m²
Part B
The power the firework is emitting is approximately 1,231.5 kW
Explanation:
Part A
The data of the firework sound heard by the two friends are;
Let 'A' represent the location of the friend at a point 150 m from the fireworks and let 'B' represent the location of the friend watching from a distance of 700 m from the firework
The distance of 'A' from the sound, r₁ = 150 m
The distance of 'B' from the sound, r₂ = 700 m
The intensity at which 'B' hears the sound, I₂ = 0.2 W/m²
The relationship between sound intensity and distance is given as follows;
[tex]\dfrac{I_2}{I_1} = \left (\dfrac{r_1}{r_2} \right )^2[/tex]
[tex]\therefore {I_1} = \dfrac{I_2}{ \left (\dfrac{r_1}{r_2} \right )^2} = I_2 \times \left (\dfrac{r_2}{r_1} \right )^2[/tex]
Plugging in the values gives;
[tex]\therefore {I_1} = 0.2 \times \left (\dfrac{700}{150} \right )^2 = \dfrac{196}{45} = 4.3\overline 5[/tex]
The sound intensity at location 'A', I₁ = 4.3[tex]\overline 5[/tex] W/m²
Part B
The relationship between power, 'P', and intensity, 'I', is presented as follows;
[tex]I = \dfrac{P}{4 \cdot \pi \cdot r^2}[/tex]
P = I·4·π·r² = 4·I·π·r²
Therefore, at point 'A', where the distance, r₁ = 150 m, and the intensity, I₁ = 4.3[tex]\overline 5[/tex] W/m², we have;
P = 4 × 4.3[tex]\overline 5[/tex] W/m² × π × (150 m)² = 1231504.32021 W
The power the firework is emitting, P ≈ 1,231.5 kW.

When a substance is poured from one container to another, its shape changes but its volume does not, what state of matter is the substance in?
A. Plasma
B. Liquid
C. Gas
D. Solid
Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.
Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.

Can someone please, please help me out here? I understand literally none of this, despite watching multiple videos and reading a few articles on Kirchoff's laws.
Answer:
Explanation:
By Kirchoff's laws, I1 + I2 = 3
I2 = 3 - I1
Following circuit on the left, V = summation of IRs
9 = I1*3 + 3*2
3*I1 = 9 - 6 = 3
I1 = 1A
I2 = 3 -1 = 2A
Following circuit on the right, V = summation of IRs
ε = I2*4.5 + 3*2
= 2*4.5 + 6
= 15V

Electrons move from the rod to the wool.
Protons move from the rod to the wool.
Electrons move from the wool to the rod.
Protons move from the wool to the rod.
Electrons move from the wool to the rod.
BEcause if they move from wool to rod, the rod has more number of electrons now. Hence making it negatively charged
The plastic rod becomes charged when electrons move from the wool to the rod to become negatively charged. Details about charge can be found below.
What is electronegativity?Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons and thus form bonds.
According to this question, a plastic rod becomes negatively charged when it is rubbed with a piece of wool.
