How does the law of inertia relate to how the planets in our solar system revolve around the sun?
Answer:
The law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.
Explanation:
Law of inertia states that a body at rest or uniform motion will continue to be at rest or uniform motion unless it is acted upon by an external force.
The gravitational force keeps the planets revolving round the sun in a uniform motion, this will continue till infinity unless equal and opposite force acts on our planets.
Therefore, the law of inertia relates to revolution of planets round the sun due to constant motion of the planets round the sun.

You perform an experiment with a long column of air and a tuning fork. The column of air is defined by a very long vertical plastic tube with a circular cross section; the upper end of the tube is open to the outside air and the lower end of the tube is filled with water. The column of air extends from the top of the water to the open end of the tube; the length of the column can be varied by changing the water level in the lower end of the tube. (The columns of air in this problem are longer than those you will have used in lab; this allows us to imagine the use of lower frequency tuning forks than those you will have used in lab.)
ou are using a tuning fork of frequency 256 Hz. For one particular water level, you hear a loud sound when the fork is struck and positioned just above the open end of the tube. When the water level is lowered by 676 mm, you again hear a loud sound.
(a) What is the wavelength of the 256 Hz sound waves in the column of air? Give your answer in meters, not mm. m
(b) What is the speed of sound in the column of air? m/s
Answer:
[tex]\lambda=4L=1.33m[/tex]
v=343m/s
Explanation:
We have to take into account the expressions
[tex]f=\frac{2n+1}{4}\frac{v_s}{L}\\L=(2n+1)\frac{\lambda}{4}[/tex]
if we assume that 256Hz is the fundamental frequency we have
[tex]f=\frac{1}{4}\frac{v_s}{L}\\\\L=\frac{1}{4}\frac{v_s}{f}=\frac{1}{4}\frac{343\frac{m}{s}}{256Hz}=0.33m[/tex]
and for wavelength
[tex]\lambda=4L=1.33m[/tex]
hope this helps!!
Answer:
a) The wavelength, λ = 1.352 m
b) The speed of the sound in the column air is v = 346.112 m/s
Explanation:
a) Frequency, f = 256 Hz
The water level is lowered by 676 mm. i.e. x = 676 * 10⁻³ m
The length, x, at which the loudest sound will be heard is λ/2
i.e. x = λ/2
Therefore the wavelength of the 256 Hz sound waves in the column air is given by the relation
λ = 2x
λ = 2 * 676 * 10⁻³
λ = 1.352 m
b) The speed of the sound in the column air:
The speed, v, is given by the relation v = f λ
speed, v = 256 * 1.352
v = 346.112 m/s

1)radius r of orbit.
2)mass m of the sun.
3) gravitational contact. show dimensionally t^2 proportional to
[tex] {r}^{3} [/tex]
Answer:
t² ∝ r³
Explanation:
Let m be the mass of the sun and m₁ be the mass of the planet and r its distance from the sun. Its gravitational force of attraction equals its centripetal force. So,
Gmm₁/r² = m₁rω² = m₁r(2π/t)² were t is the period of orbit of the planet
Gm/r² = 4π²r/t²
rearranging we ave
t² = (4π²/Gm)r³ since k = 4π²/Gm = constant
t² = kr³ and
t² ∝ r³

If a system absorbs 300.5J of heat and performs 1.50kJ of work on the surroundings, what is the ΔE?
Complete question:
If a system absorbs 300.5J of heat and performs 1.50kJ of work on the surroundings, what is the change in internal energy of the system ΔE?
Answer:
Change in internal energy of the system is 1800.5 J
Explanation:
Given:
heat transferred to the system, Q = 300.5J
work done on the surroundings, W = 1.50kJ
Change in internal energy of the system ΔE, can be calculated by applying thermodynamic equation of change in internal energy, work done and heat transferred.
ΔE = Q + W
Where;
ΔE is change in internal energy
Q is heat transfer
W is work done
ΔE = 300.5 J + 1500 J
ΔE = 1800.5 J
Therefore, change in internal energy of the system is 1800.5 J
Answer:
The intern energy of the system is -1199.5 J
Explanation:
Given:
System absorbs 300.5 J of heat
Performs 1.5 kJ = 1500 J of work on the surroundings
Question: What is the ΔE?
When a system absorbs heat, it will have a positive sign, therefore +300.5 J
When the system performs work on the surroundings, its sign will be negative, therefore, -1500 J
According the first law of thermodinamic:
ΔE = q + W = 300.5 - 1500 = -1199.5 J
Two balls of the same shape and size have charges of +8 and-2. The balls are brought together, allowed to touch, and then separated. What is the net charge on each ball now?
Explanation:
Initially, two balls of the same shape and size have charges of +8 and-2. The balls are brought together, allowed to touch, and then separated.
When they are touched, the total charge is evenly distributed among the whole surface and they behaves as if it is a single piece. Net charge at this point is +8-2=6 C. When they are separated, each ball will have a charge of 6/2 = 3 C.
When two identical balls with charges of +8 and -2 are brought into contact and then separated, each ball ends up with a net charge of +3, due to the conservation of charge and even distribution across identical conducting surfaces.
When two balls of the same shape and size with charges of +8 and -2 are brought together, allowed to touch, and then separated, the net charge on each ball is a result of the equal distribution of the total charge across both balls. Initially, the total charge is the sum of +8 and -2, which equals +6. Since the balls are identical and they come into contact, this total charge of +6 is evenly divided between them. Therefore, after they are separated, each ball will have a net charge of +3.
This occurs because, when conducting objects touch, charges redistribute themselves evenly across the surfaces of the objects until they reach an equilibrium while maintaining the conservation of charge. In simpler terms, the total quantity of charge is conserved, and since the two balls are identical, the charge divides evenly.

b. If you double the frequency of the sound wave, determine its speed.
c. What happens to the wavelength if you cut the frequency in half? How do you know?
I'll throw in brainiest too.
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles

Answer:
I₂ = I₀ 1/4
Explanation:
For this exercise we use the definition of intensity which is the power per unit area
I = P / A
The emitted power is constant, so
P = I A
We can write this equation for the start and end point with index 2
I₀ A₀ = I₂ A₂
I₂ = I₀ A₀ / A₂
The spot area is the area of the circle
A₀ = π r₀²
We substitute
I₂ = I₀ r₀² / r₂²
It indicates that the radius of the spot is twice the initial radius
r₂ = 2 r₀
I₂ = I₀ (r₀ / 2 r₀)²
I₂ = I₀ 1/4
A 7.80-g bullet moving at 540 m/s strikes the hand of a superhero, causing the hand to move 5.10 cm in the direction of the bullet's velocity before stopping. (a) Use work and energy considerations to find the average force that stops the bullet.
Answer:
[tex]F = 22298.824\,N[/tex]
Explanation:
According to the Principle of Energy Conservation and the Work-Energy Theorem, the bullet has the following expression:
[tex]U_{g,A} + K_{A} = U_{g,B} + K_{B} + W_{loss}[/tex]
[tex]W_{loss} = U_{g,A}-U_{g,B} + K_{A}-K_{B}[/tex]
[tex]F\cdot \Delta s = \frac{1}{2}\cdot m \cdot [v_{A}^{2}-v_{B}^{2}][/tex]
The average force exerted on the bullet to stop it is:
[tex]F = \frac{m\cdot [v_{A}^{2}-v_{B}^{2}]}{2\cdot \Delta s}[/tex]
[tex]F = \frac{(7.8\times 10^{-3}\,kg)\cdot [(540\,\frac{m}{s} )^{2}-(0\,\frac{m}{s} )^{2}]}{2\cdot (0.051\,m)}[/tex]
[tex]F = 22298.824\,N[/tex]
Answer:
22298.82N
Explanation:
The bullet has a kinetic energy: ½*m*v²
mass of bullet = 7.80g = 7.80÷1000 = 0.0078kg
distance in meter =5.10cm = 5.10÷100 = 0.051meter
K.e = 0.5 ×0.0078 × 540× 540
K.e = 1137.24 J
When the bullet stops this energy goes to zero, as the energy must be conserved the work done by the head of the superhero must be equal to the original energy of the bullet:
W= K
Considering an average constant force, the work can be calculated as:
W=F*d=K
Solving for F:
F = K/d
1137.24 J/ 0.051m
= 22298.82N

A 7310 kg space probe, moving nose-first toward Jupiter at 88.3 m/s relative to the Sun, fires its rocket engine, ejecting 54.0 kg of exhaust at a speed of 246 m/s relative to the space probe. What is the final velocity of the probe
Answer:
[tex]v_{1f} = 90.12m/s[/tex]
Explanation:
As we know that Probe along with rocket system is an isolated system
So here net force on this system must be zero
and we can use momentum conservation for this system
So we will have
[tex](m_1 + m_2)v_{i} = m_1v_{1f} + m_2v_{2f}[/tex]
here we know that
[tex]7310 \times 88.3 = (7310- 54)v_{1f} + 54(v_{1f} - 246)[/tex]
[tex]645473 = 7310\times v_{1f} - 13284\\658757 = 7310 \times v_{1f}[/tex]
so we have,
[tex]v_{1f} = 90.12m/s[/tex]
Answer:
Final velocity of Probe; V_f = 656.314 m/s
Explanation:
We are given;
Mass of space probe; m_i = 7310 kg
Initial velocity of probe ; v_i = 88.3 m/s
Mass of exhaust fuel; m = 54 kg
V_rel = 246 m/s
Mass of fuel; m_f = m_i - m = 7310 kg - 54kg = 7256 kg
From Rocket equation;
V_f - V_i = V_rel[In(m_i/m_f)]
Where V_f is final velocity of probe.
Thus, plugging in the relevant values to get ;
V_f - 88.3 = 246[In(7310/7256)]
V_f - 88.3 = 246 x 2.309
V_f - 88.3 = 568.014
Thus, V_f = 568.014 + 88.3 = 656.314 m/s
The upward force exerted on an object falling through air is ______.
A. terminal velocity B. momentum
C. air resistance D. weightless
The upward force exerted on an object falling through air is air resistance. The correct option is C.
What is air resistance?When an object moves through air, it creates a force called air resistance. This force basically acts in the inverse way of direction of a body moving via air.
The frictional force of air resistance acts on the moving body. When a body moves, air resistance slows it down.
When an object moves through the air, it encounters air resistance. Resistance varies depending on the velocity, shape, and area of the object. The higher the air resistance, the faster an object moves and the larger its area.
When air pushes against a moving object, it creates air resistance force. Frictional forces include air resistance. Force is always applied against the motion of an object.
Thus, the correct option is C.
