Answer:
A responding variable is something that “responds” to changes you make in an experiment. It's the effect or outcome in an experiment. ... The variable you change would be the amount of light. The responding variable would be the height of the plants.
hope it will help you
In order to add or subtract numbers expressed in scientific notation, it is important that the powers of 10 in the numbers should have the same index or else you cannot readily add or ubtract these numbers. We do as follows:<span>
a. 5.80 x 10^9 s +3.20 x 10^8 s
We need to adjust one of the numbers since they do not have the same indices. We move one place to the left of the second number making it .320 x 10^9 s. Then, we can add the numbers now:
</span>5.80 x 10^9 s +.320 x 10^9 s = 6.12 x 10^9 s<span>
b. 4.87 x 10^-6 m - 1.93 x 10^-6 m
We can subtract the numbers directly since they have the same indices.
</span>4.87 x 10^-6 m - 1.93 x 10^-6 m = 2.94 x 10^-6 m
The direction is from the west
Explanation:
By the second law of Newton we get the relation
F = ma
Answer:
SECOND LAW OF NEWTON
Explanation:
When the rocket fires the engines the gases leave at high speed and collide with the space station, transferring an impulse given by the expression
I = F t = Δp
As we can see this expression is a form of Newton's second law
F = m a
a = dv / dt
F = m dv / dt
F dt = m dv
p = mv
F dt = dp
Therefore the station moves through the SECOND LAW OF NEWTON
