Answer & Explanation:
Bronze is one of the earliest metals known to man. It is defined as an alloy made of copper and another metal, usually tin. Compositions vary, but most modern bronze is 88% copper and 12% tin. Bronze may also contain manganese, aluminum, nickel, phosphorus, silicon, arsenic, or zinc.
Converting 209 km/hr to m/s:
209 km/hr = 58.0 m/s
Contact distance = 0.1 m
Using the equation of motion:
2as = v² - u², where initial velocity is 0
a = (58)² / (2 x 0.1)
a = 1.68 x 10⁴ m/s²
Answer: 44.57°C
Explanation:
The following can be deduced from the question:
Specific heat of water = 4.186 J/kg
From the question, we can infer that 625 × 4.186 joules of heat will be lost when there's a 1°C drop of water.
We then calculate the amount if degrees that it'll take to cool for 7.96 x 10⁴J. This will be:
= 7.96 × 10⁴ /(625 × 4.186)
= 79600/(625 x 4.186)
= 79600/2616.25
= 30.43°C
The final temperature will then be:
= 75.0°C - 30.43°C
= 44.57°C
Answer:
M. A change that causes the gene to increase the amount of lactase ir produces will increase a person's ability to break down lactose
Explanation:
Lactose is a sugar found in dairy products. Humans require an enzyme, called lactase, to break down the sugar in the body. This enzyme is produced by the lactase gene.
Some people have some variation in their gene that means they do not produce very much lactase. This means they do not produce sufficient amount of the enzyme to break down the sugar lactose found in milk. This causes them to feel ill and get abdominal pain when they eat dairy, because their body can't break down the sugar.
Therefore, a change in the gene that causes it to produce more lactase will make people more able to consume lactase. A change that decreases the amount of lactase enzyme will have the opposite effect.
The source of protein and minerals found in dairy are not processed by lactase, so R is not correct.
Answer: clay
Explanation:
Florida is mainly influences by Spanish culture, so building with clay and wood would make sense, knowing that that is how pueblas are built.
