Answer:
correct is d) a ’= g / 2
Explanation:
For this exercise let's use the kinematics equations
On earth
v = v₀ - a t
a = (v₀- v) / T
On planet X
v = v₀ - a' t’
a ’= (v₀-v) / 2T
Let's substitute the land values in plot X
a’= a / 2
Now let's use Newton's second law
W = ma
m g = m a
a = g
We substitute
a ’= g / 2
So we see that on planet X the acceleration is half the acceleration of Earth's gravity
I can't particularly place what Icelandic contributed.
But every other culture contributed majorly.
So I would go for option b.
The planet closest to the sun; Mercury.
Answer:
D 5 V
Explanation:
Without seeing the whole circuit it is impossible to say for certain.
However the simplest circuit would produce a value of
FV = IR = 0.25(20) = 5 v
A. To find work we need to know F and S; to find power we need to know F and V
