Answer:
Land and sea breeze
Explanation:
This uneven warming of the land during the day results in the phenomenon called land and sea breeze.
- During the day, the land heats up faster than the nearby ocean.
- Ocean is made up of water with a high specific heat capacity.
- This derives pressurized air near the surface of the land to the ocean.
- At night, the ocean does not easily lose heat after the land has lost its own.
- Pressurized air moves from the ocean to the land.
- This causes the warming of the land during the night.
Answer: 12g
Explanation:
The amount of energy (Q) required to raise the temperature of a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = 216 joules
Mass of aluminium = ? (let unknown value be Z)
C = 0.90 JºC-1g-1
Φ = (Final temperature - Initial temperature)
= 35°C - 15°C = 20°C
Then, Q = MCΦ
216 J = Z x 0.90 JºC-1g-1 x 20°C
216 J = Z x 18 J°g-1
Z = (216J/18 J°g-1)
Z = 12g
Thus, the mass of the aluminium is 12grams
Answer: tapeworm-human
Explanation:
Tapeworm, also known as Taenia solium is a parasitic nematode that gets into the human intestine, depriving humans of food nutrients. Its effects include diarrhoea, abdominal pains and general weakness of the human body.
Thus, the relationship of tapeworm and humans is parasitic because the tapeworm benefits at the human expense.
