Answer:
A. Sulfur _________ group 16 chalcogens
B. Sodium _________ group 1 alkali metals
C. Argon _________ group 18 noble gases
D. Silicon _________ group 14 carbon family
E. Chlorine _________ group 17 halogens
F. Phosphorus_________ group 15 pnicogens
Answer:
When you are performing spike it's most effective to strike the ball from the right or left side at a sharp downward angle. Whether you are spiking the ball from the right or left front position, position yourself behind the 10-foot line (attack line), which is the line that is about four steps away from the net.

</span>Meiosis has 2 cell divisions but mitosis has only one cell
division. Meiosis I is same as mitosis because parent cell produces diploid
cells. But the difference between meiosis and mitosis is after the complete
process meiosis produces genetically different haploid daughter cells and
mitosis produces genetically same diploid daughter cells.

</span>The main advantage of the sexual reproduction is It helps to produce offspring which can be
well adapted to the environmental conditions due to the genetically
differentiations. Hence, there are various types of offspring in the population.
But the disadvantage is it requires two parents and it requires more time than
asexual reproduction.
<span>3.
</span>Advantages
of asexual reproduction are it requires only parent, time for the process is
relatively low, it produces genetically identical offspring. The main
disadvantage is due to the production of genetically identical offspring, the
survival rate is low when there is a disaster.
<span>4.
</span><span>The
organism can do either sexual reproduction or asexual reproduction to produce
offspring. If it is difficult to find a partner to mate, the living being can
do asexual reproduction to make offspring in a short period of time. When the
organism needs genetically different offspring for survival, they can do sexual
reproduction.</span>
Answer:
option (a) 0.61 s
Explanation:
Given;
Time taken by the ball to reach the ground = 0.50 s
Let us first calculate the distance through which the ball falls on the ground
from the Newton's equation of motion, we have
where,
s is the distance
a is the acceleration
t is the time
here it is the case of free fall
thus, a = g = acceleration due to gravity
u = initial speed of the ball = 0
on substituting the values, we get
or
s = 1.225 m
Now,
when the elevator is moving up with speed of 1.0 m/s
the initial speed of the ball = -1.0 m/s (as the elevator is moving in upward direction)
thus , we have
or
or
4.9t^2 - t - 1.225 = 0
or
t = 0.612 s
hence, the correct answer is option (a) 0.61 s
