Answer:

By the there is no change in the temperature until the phase change is complete. It is that during the phase change the energy supplied is used only to seperate the molecules no part of it is used to increase the relating to a result from the motion energy of the molecules so it's temperature will not rise since the relating to a result from the motion energy of molecules remains the same .

I hope this might help u

Answer:

It depends on where the temperature is dropping, in which body so to speak. Generally, the temperature adapts to the two bodies, for example if a hot piece of metal meets a cold one, the two will continue until they are at an equal temperature, an intermediate temperature.

Yakvenalex [24]

Answer:

Gravity is dependent on the mass of two bodies and the distance between them. There is a strong gravitational attraction between Earth and the Moon because they’re relatively close to one another. There is a strong gravitational attraction between Earth and the Sun because the Sun is so massive

A sample of gas is enclosed in a container of fixed volume. Identify which of the following statements are true. Check all that

motikmotik

Answer:

B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.

C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.

E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.

natima [27]

Answer:

Nature of Sound Waves Sound is a wave that is created by perturbations and propagated through a medium from one location to another. Type of Wave: longitudinal wave. A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a medium of propagation and a disturbance. Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. Anatomy of a Wave:

By method of dimension show that the following equation are homogenous.

il63 [147K]

Answer:

Proof in explanataion

Explanation:

The basic dimensions are as follows:

MASS = M

LENGTH = L

TIME = T

Given equation is:

$H = \frac{u^2Sin^2\phi}{2g}$

where,

H = height (meters)

u = speed (m/s)

g = acceleration due to gravity (m/s²)

Sin Ф = constant (no unit)

So there dimensions will be:

H = [L]

u = [LT⁻¹]

g = [LT⁻²]

Sin Ф = no dimension

Therefore,

$[L] = \frac{[LT^{-1}]^2}{[LT^{-2}]}\\\\\ [L] = [L^{(2-1)}T^{(-2+2)}]$

[L] = [L]

Hence, the equation is proven to be homogenous.

ii)

$F = \frac{Gm_1m_2}{r^2}\\\\$

where,

F = Force = Newton = kg.m/s² = [MLT⁻²]

G = Gravitational Constant = N.m²/kg² = (kg.m/s²)m²/kg² = m³/kg.s²

G = [M⁻¹L³T⁻²]

m₁ = m₂ = mass = kg = [M]

r = distance = m = [L]

Therefore,

$[MLT^{-2}] = \frac{[M^{-1}L^{3}T^{-2}][M][M]}{[L]^2}\\\\\ [MLT^{-2}] = [M^{(-1+1+1)}L^{(3-2)}T^{-2}]\\\\$

[MLT⁻²] = [MLT⁻²]

Hence, the equation is proven to be homogenous.
