The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _ and the _ of the conductor. A. length, speed
B. color, capacitance
C. resistance, current
D. distance, circumference

Answers

Answer 1

Answer:

Answer:

Length and speed.

Explanation:

According to Faraday's law, the voltage induced in the conductor is equal to the product of magnetic field, length and speed of the conductor.

The formula to find the induced voltage in the conductor is:

ξ = Blv

Here, ξ= emf induced, B is magnetic field, l is the conductor length and v is the conductor speed.

From the above formula, it is clear that voltage of a conductor depends upon the length and speed of the conductor.

Thus, the correct answer is option (A)

Answer 2

Answer: The correct answer is A). Length, Speed.

Which of the following are specialized cells?blood cells
muscle cells
bone cells
all of the above

Answers

The answer is all of the above.

Cells are all similar, but still, they differ in size, shape, function. All of this depends on their role in the body. A blood cell, muscle cell, bone cell, for example, are similar enough on some basic level. Still, each of these cells is specialized to work in the special way the body needs to. They are all specialized for different functions.

A geneticist studying fruit flies finds that out of a total population of 400 he observes only 12 flies with red eyes, the rest have black eyes. The percentage of flies with red eyes is

Answers

The question says that in a population of 400 flies, only 12 had red eyes.

The total number of fruit flies in this case is 400.

and

The total number of flies having red eyes is 12.

To find out the percentage of fruit flies having red eyes, following formula is used:

$\frac{\textup{total number of flies having red eyes}}{\textup{total number of flies}}* 100$

So, the percentage of red eye individual is;

$(12)/(400)* 100 \n \n=3$

Hence, the total percentage of red eye offspring is 3%.

Given: Total population of flies is 400, number of flies with red eyes is 12.

To find: The percentage of flies with red eyes.

Method: We know the total number of red eyed flies and the size of population. The percentage can be found by diving the number of red flies by the size of the population of the flies.

Solution:

Percentage of red eyed flies = $(12 * 100)/(400) = (3*100)/(100) = 3$

Hence the answer is 3% of the flies are red eyed.

?Which is the order of organisms from the shortest life cycle to the longest?firefly → moss → pea plant
moss → pea plant → firefly
firefly → pea plant → moss
pea plant → firefly → moss

Answers

Answer:

The correct answer is firefly → pea plant → moss.

Explanation:

Fireflies average life span is about 2 months for adults. Pea plants are annual plants and life span is of one year, it takes place from winter to the end of summer.

Moss life span is longer than pea plants and fireflies. Their life span depends on their species which can range from two to ten years. Generally, it considered as 10 years.

Thus, the correct answer is firefly → pea plant → moss.

Answer:

c. Firefly, peaplant, moss.

Explanation:

Fireflies live for only a couple weeks. Pea plants live for about 100 days. Moss lives for about 4 months.
