Which would increase the speed of a sound wave?
- A wave passes from a solid to a liquid while remaining the same temperature.
- The medium increases in temperature while remaining in the same phase.
- The medium decreases in temperature while remaining in the same phase.
- A wave passes from a liquid to a gas while remaining the same temperature.
Answer:
B. The medium increases in temperature while remaining in the same phase
Explanation:
Good luck on all your tests and Exams!
The sound wave will increase when the medium increases in temperature while remaining in the same phase.
What is a sound waves?Sound waves are composed of compressions and rare factions. Sound is a mechanical wave hence it moves by the vibration of air particles.
As such, the sound wave will increase when the medium increases in temperature while remaining in the same phase.

Can someone one help me please !!!
Answer:
Current in the circuit(I) = 0.5 ampere
Explanation:
Given:
Number of resistors = 2 (10 ohm each)
Series of resistors
EMF = 10 volt
Find:
Current in the circuit(I)
Computation:
Total resistance in series = R1 + R2
Total resistance in series = 10 + 10
Total resistance in series = 20 ohm
Current in the circuit(I) = EMF / Total resistance in series
Current in the circuit(I) = 10 / 20
Current in the circuit(I) = 0.5 ampere

[tex]what \: is \: water \: cycle \: \: {?} [/tex]
Answer:
water cycle show the continuous movement of water with in the earth and atmosphere
Explanation:
Hope this helps :)
The water cycle is the process through which water evaporates from the earth's surface, rises into the atmosphere, cools and condenses into rain or snow in clouds, and then falls back to the surface as precipitation. Water that falls on land gathers in rivers and lakes, soil, and porous rock strata, and much of it goes back into the seas to evaporate. Water flows in and out of the system.

the International System of Units, the fundamental units are: The meter (symbol: m), used to measure length. The kilogram (symbol: kg), used to measure mass. The second (symbol: s), used to measure time. The ampere (symbol: A), used to measure electric current.
If we keep on applying force on a material object, can it gain speed of light?
Answer:
As an object moves faster, its mass increases. ... Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.
If the angle of a light ray in air is 25∘ and it enters a substance with a refracted angle of 13∘, what is the index of refraction of the substance?
A). 0.65
B). 0.53
C). 1.92
D). 1.88
Answer:
Explanation:
The formula for this is
[tex]n_1sin\theta_1=n_2sin\theta_2[/tex] where the index of refraction of air is 1.00. Filling in and solving for n2:
1.00sin(25) = n₂sin(13) and
1.00(.423) = n₂(.225) and
[tex]\frac{1.00(.423)}{.225}=n_2[/tex] so
[tex]n_2=1.88[/tex], choice D.

A 1234 kg freight car moving at 6 m/s runs into a 2468 kg freight car at rest. They stick together upon collision. What was the final combined speed?
Answer:
2 m/s
Explanation:
Applying,
The law of conservation of momentum
Total momentum before collision = Total momentum after collision
mu+m'u' = V(m+m')............... Equation 1
Where m = mass of the first freight car, m' = mass of the second freight car, u = initial velocity of the first freight car, u' = initial velocity of the second freight car, V = final combined velocity/ speed.
make V the subject of the equation
V = (mu+m'u')/(m+m')........... Equation 2
From the question,
Given: m = 1234 kg, m' = 2468 kg, u = 6 m/s, u' = 0 m/s (at rest)
Substitute these values into equation 2
V = [(1234×6)+(2468×0)]/(1234+2468)
V = 7404/3702
V = 2 m/s

a boy throws a ball straight up into the air. it reaches its highest point after 4 seconds.how fast was the ball going when it left the boy's hand
Answer:
Explanation:
The most important thing to remember about parabolic motion in physics is that when an object reaches its max height, the velocity right there at the highest point is 0. Use this one-dimensional motion equation to solve this problem:
v = v₀ + at and filling in:
0 = v₀ + (-9.8)(4.0) **I put in 4.0 for time so we have more than just 1 sig fig here**
0 = v₀ - 39 and
-v₀ = -39 so
v₀ = 39 m/s

A charge particle is moved through a potential difference of 154.5 V and experiences a
change of electric potential energy of 4.26 x 10-8 J. What is the charge of the particle?
Answer:
2.76×10⁻¹⁰ C
Explanation:
Applying,
V = W/q................... Equation 1
Where V = Electric Potential, E = Electric potential energy, q = charge.
make q the subject of the equation
q = W/V................ Equation 2
From the question,
Given: W = 4.26×10⁻⁸ J, V = 154.5 V
Substitute these values into equation 2
q = 4.26×10⁻⁸/154.5
q = 2.76×10⁻¹⁰ C

A. Remain same
B. Be doubled
C. Be halved
D. Become zero
(Ans with explanation please)
Answer:
will be doubled
Explanation:
This is because when a dielectric material is inserted between the plates of capacitors the capacitance increases to
c = ke Co .
where ke is called the dielectric constant and Co is the capacitance without a dielectric material

Describe the mathematical relationship between the gravitational
potential energy of an object and its height above a reference point.
Answer:
∆p.e = mg∆h
Explanation:
Take height reference be h1 while height final be h2.
∆h = (h2 - h1)
m = m
g = g
•°• ∆p.e = mg(h2 - h1)
=> ∆p.e = mg∆h
