1 answer:

5 0

Cumulus clouds are easy to distinguish because they look like piles of cotton. They have rounded edges. The Latin word 'cumulus," is loosely translated as "heap," in English.

Altostratus are mid-level clouds that resemble an overcast sky. Predominantly grey, they spread out widely and is usually associated with light rain. It can morph into a nimbostratus, which are clouds that carry heavy rain.

Cirrus clouds are thin and wispy. They are high-level clouds that often appear bright yellow just as the sun rises and red after the sun sets.

Nimbostratus clouds are dark thick-layered clouds. "Nimbus," is Latin which means rain and "stratus," means spread-out.

Fog are clouds nearest to the surface. They are also called stratocumulus clouds. These are stratus clouds that form near the ground.

Which of the following best describes a substance in which the temperature remains constant while at the same time it is experie

katen-ka-za [31]

Answer:

The right option is (d) substance undergoing a change of state

Explanation:

Latent Heat: Latent heat is the heat required to change the state of a substance without change in temperature. Latent heat is also known as hidden heat because the heat is not visible. The unit is Joules (J).

Latent heat is divided into two:

⇒ Latent Heat of fusion

⇒ Latent Heat of vaporization.

Latent Heat of fusion: This is the heat energy required to convert a substance from its solid form to its liquid form without change in temperature. E.g (Ice) When ice is heated, its temperature rise steadily until a certain temperature is reached when the solid begins to melts.

Latent Heat of vaporization: This is the heat required to change a liquid substance to vapor without a change in temperature. The latent heat depend on the mass of the liquid and the nature of the liquid. E.g When water is heated from a known temperature its boiling point (100°C) When more heat is supplied to its boiling temperature, it continue to boil without a change in temperature.

From The above, Latent heat brings about a change of state of a substance at a steady temperature.

The right option is (d) substance undergoing a change of state

kompoz [17]

Answer:

both technician A and Technician B are correct

Explanation:

Technician A says balance shafts are used to counteract vibration created in the engine. Technician B says proper balancing of the engine is important for smooth operation. Which technician is correct

In piston engine engineering, a balance shaft is an eccentric weighted shaft that counteracts vibrations in engine designs that are not inherently balanced. They were first invented and patented by British engineer Frederick W. Lanchester in 1904. ... .The balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force. Unavailability of the balance shaft can cause excessive vibration to the engine thereby damaging the oil pump and resulting to engine failure.

Can ya pls answer dis rq!

PSYCHO15rus [73]

Answer:

Below

Explanation:

Recommended protein sources

1. Lean meat such as chicken or fish

Advantages : they are high quality sources of protein, and contain all 8 essential amino acids, which is why they are considered a complete protein

2. Animal products like eggs and greek yogurt

Advantages : these foods also contain all 8 essential amino acids, making them a complete protein

3. Pulses like beans and lentils

Advantages : tends to be lower in calories and fat than animal-based protein sources, as well as being higher in fiber and essential nutrients

Hope this helps!
