Dose sound travel faster in a warm room or a cold room? explain your answer
dusya [7]

Answer:Sound travel faster in warm room.

Explanation:The speed of sound depends on the temperature of the medium. Mathematically, the relation between the speed of the sound and the temperature is give by:v=

is the ratio of the specific heats

R is the gas constant

T is the temperature of the medium

We know that the temperature of the warm room is more as compared to the cold room.

So, it is clear that the sound travel faster in a warm room. The particles move faster when the temperature is high.

A solid block of metal is at its melting temperature. it takes 24j to melt 6kg of a metal. what is the latent heat of fusion of
Marina86 [1]

The Latent heat of fusion is also known as the Enthalpy of Fusion. It is a kind pf change in enthalpy.

<h3>Brief explanation of Latent Heat of Fusion? </h3>

The latent heat of fusion, is the change in enthalpy that takes place when energy, typically heat, is provided to a specific quantity of a substance to causes it to change from a solid state to a liquid state at a constant pressure.

For instance, 1 kilogram of ice melts at 0 °C at a variety of pressures, absorbing 333.55 kJ of energy without causing a change in temperature.

The heat of solidification, which occurs when a substance changes from a liquid to a solid, is equal and opposing.

This energy includes the contribution necessary to displace its surroundings against ambient pressure in order to accommodate any corresponding change in volume.

The melting point or the freezing point, depending on the situation, is the temperature at which the phase transition takes place. Conventionally, unless otherwise stated, the pressure is taken to be 1 atm (101.325 kPa).

<h3>Calculation</h3>

The formula of latent heat of fusion is L= q/m

Here q is the heat provided and m is the mass of the object.

So, L = 24j/6kg

L= 4j/kg

So, the latent heat of fusion is 4 j/kg

A package is dropped from a helicopter moving upward at 15m/s. If the helicopter was 1000m above the ground when the package was
sveticcg [70]

Answer:

yi = Initial height of the helicopter

yf = final height of the helicopter

vyi = component of the initial vertical velocity of the helicopter

g = gravity constant (9.8m/s^2)

yf = yi + vyideltat - 1/2gt^2

0m = 1000m + (15m/2)deltat - 1/2(9.8m/s^2)t^2

-1000m = (15m/s)t - (-4.9m/s^2)t^2

Use the quadratic formula

4.8t^2 - 15t - 1000 = 0

t1 = 15.75s and t2 = -12.65

t2 is rejected, time can't be negative

Thus, it takes 15.75s before the package strikes the ground.
