Answer:

25100A

Explanation:

t= 1ms = 0.001s

q = 25.1C

From the relationship between charge and current , the charge is equal to the product of current and time

q = i×t

Where q = charge

i = current

t = time

i = q/t = 25.1/0.001

i = 25100A.

A bird takes off from the tree and after 5 s is flying at a speed of 10 m/s. Calculate
Volgvan

Answer:

10miles/second

Explanation:

Change in velocity of the bird is expressed as the difference between the final velocity and initial velocity of the body.

Change in velocity = Final velocity - initial velocity

Since the bird takes off from the tree, the initial velocity of the bird = 0miles/sec

Final velocity = 10miles/secs

Change in velocity = 10-0

Change in velocity = 10miles/second

Why is it important for body cell to have twice and many chromosomes as sex cells?
prisoha [69]

Why sex cells only need half the number of chromosomes compared to other cells in the body?  As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
