Answer:
the dependent variable is the one that changes because the independent variable was changed. The dependent isn't intentionally manipulated
Explanation:
Answer:2
Explanation:
Given
and 
and 
are the acceleration of 1 and 2
Suppose T is the Tension
then for block 2
For block 1
equate 1 and 2
where 
thus we can see that a is less than g
therefore 
Answer:
lamda=10.5m
Explanation:
using the equation of progressive wave.
y=Asin(wt-kx)
comparing the two equations together, we have
kx=0.6x , k=0.6
k=2π/λ
0.6=2*3.142/λ
cross multiply
0.6λ=6.284
divide both sides by 0.6
λ=6.284/0.6
λ=10.47m
approximate
λ=10.5m
Answer:
If it points the other way, the fields subtract, for a lower energy, and so the magnet prefers to turn to point in this way. Magnets in uniform fields feel torques which make them turn around if they are not pointing in the right direction, but there is no net force making the magnet want to levitate.
Explanation:
Answer:
-
Both exceed the matter-energy equivalent of luminous matter
- Dark matter has only an attractive gravitational effect, while the dark energy is repulsive in nature
Explanation:
Dark matter is defined as the matter which consists of about 85% of the total matter of the universe and is no-baryonic in nature.
It is attractive in nature and exerts gravitational pulling effect. Even individual galaxies are under the influence of dark matter. It is way more powerful than the visible matter.
Dark energy is that form of energy which is said to be responsible for the universe's expansion and is repulsive in nature
