Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that
so if we double the charge on
and double the distance to
we plug these into the equation to find
<span>
</span>
So we see the new force is exactly 1/2 of the old force so your answer should be
if I can remember my physics correctly.
Answer: 1.95s
Explanation:
Given
ma = 290 cos 34.9 - fk
fk = 290 cos 34.9 - ma
fn = mg + 400 sin Φ
fn = 290 + 400 sin 34.9
fn = 290 + 228.9
fn = 518.9
fk = fn * uk
uk = 0.57
290 cos 34.9 - ma = 518.9 * 0.57
290 cos 34.9 - ma = 295.8
290 cos 34.9 - 295.8 = ma
ma = -58
m = 290/10 = 29
a = 58/29
a = 2
Using equation of motion
S = ut + .5at²
3.8 = 0 + .5*2*t²
3.8 = t²
t = 1.95s
<span>The answer would be: b. biosphere, atmosphere, and geosphere
The biosphere is made by the ecological system so the plants should be biosphere. The carbon dioxide is taken by the plant from the air which was the atmosphere. The nutrient is taken by the plant from the soil which is the geosphere.</span>
We use only one variable at a time to find the accurate result. We want to see how the result of experiment changes everytime with a single variable.
Answer:
Normative
Explanation:
It is normal occurance but not unnatural
