Sound waves produced by a vibrating object are _____.

Answer: 1) Sound waves produced by a vibrating object are compressional waves. The reason being that the matter in the medium moves back and forth in the same direction that it travels. 2) Loudness is the human perception of sound wave intensity. 3) The process of detecting objects by bouncing sounds off them is called echolocation. It is also called bio sonar and animals like bats use it to detect objects near them.

I hope it helps, Regards.

Over [174]

Answer:

The neutral wire and the ground wire.

Explanation:

The black wire is the hot wire

The neutral wire provides the return path for the current provided by the hot wire.

The ground wire is connected to any metal parts in an appliance for example microwave.

A standard electrical outlet has three wires connected to it: the hot, the neutral, and the ground. There is no potential difference between the neutral wire and the ground wire.

A 50 cm^3 block of iron is removed from an 800 degrees Celsius furnance and immediately dropped into 200 mL of 20 degrees Celsiu
NNADVOKAT [17]

Answer:

 % of water boils away= 12.64 %

Explanation:

given,

volume of block  = 50 cm³ removed from temperature of furnace = 800°C

mass of water = 200 mL = 200 g

temperature of water  = 20° C

the density of iron = 7.874 g/cm³ ,

so the mass of iron(m₁)  = density × volume = 7.874 × 50 g = 393.7 g

the specific heat of iron C₁ = 0.450 J/g⁰C

the specific heat of water Cw= 4.18 J/g⁰C

latent heat of vaporization of water is L_v = 2260 k J/kg = 2260 J/g

loss of heat from iron is equal to the gain of heat for the water

m_1\times C_1\times \Delta T = M\times C_w\times \Delta T + m_2\times L_v

393.7\times 0.45\times (800-100) = 200\times 4.18\times(100-20) + m_2\times 2260

m₂ = 25.28 g

25.28 water will be vaporized

% of water boils away =\dfrac{25.28}{200}\times 100

 % of water boils away= 12.64 %

a bag of sugar is found to have the same weight on planet earth as an identical bag of dry sawdust on planet Jupiter explain why
disa [49]

Answer:

Because Jupiter is a much larger planet than Earth, its gravitational pull is 240% stronger than that of earth. This is why sawdust, which is lighter than its equivalent measure of sugar would weigh more on Jupiter.

Explanation:

Let's assume that a type of bag can contain 50 kilograms of sugar. If that same bag was filled up with sawdust instead, it would weigh far less than 50Kg.

If that bag of sawdust, on earth weighed 35Kg for instance, on Jupiter, the new weight would be:

35Kg x 2.4 = 84Kg

Put differently, Jupiter simply has a stronger gravitational pull than earth. This extra pull is attributed to its size.

Cheers
