Explanation:
Power is found through the equation,
P
=
W
t
W
is the work done in joules
t
is the time taken in seconds
Work done is given by the equation,
W
=
F
⋅
d
F
is the force exerted in newtons
d
is the distance moved in meters
And so, the work done is:
W
=
35
N
⋅
10
m
=
350
J
Therefore, the power used up is:
P
=
350
J
5
s
=
70 W
Answer:
Semiconductors
Explanation:
Semiconductors are materials whose main characteristic is that they can act as conductors or as insulators depending on some conditions such as temperature or the electric field.
There are also chemical elements that have semiconductor capacity, for example silicon.
For this property, semiconductors are widely used for in electronics, among these applications is the manufacture of devices such as transistors, which are electronic divices that allow or disable current flow.
Answer:
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
Answer:
