As you know, plants are usually green<span>, which means that most other colors are absorbed. One of the most common pigments is called chlorophyll, and one of the varieties is responsible for the </span>green<span> color of plants; it strongly absorbs </span>blue<span> and </span>red<span>light, which leaves only the </span>green<span> light to make it to our eyes.</span>
For a questions which involves constant acceleration, you can use the SUVAT equations.
S - displacement - -26.5m ( If you to take the right as a positive value - since displacement is a vector quantity involving direction and magnitude)
U
V - Final Velocity - unknown
A - Acceleration - -1.8m/s^2
T - Time - 3.81s
s = vt - 1/2at^2
-26.5m = 3.81v - 1/2 • -1.8 • 3.81^2
Rearrange
-26.5m/-1/2•-1.8•3.81^2=3.81v
3.81v = -2.028~
v = -0.532~ (3sf)
Answer:
What is the quantity that has the units of m/s²?
- Velocity
- <em><u>Acceleration✓</u></em>
- Force
- Momentum
<em><u>Acceleration</u></em> is the quantity that has the units of m/s².
Explanation:
Acceleration is the rate of change of velocity.
Acceleration=(Final velocity-Initial velocity)/Time.
Answer:
I think the answer is Nonmetal...
By definition, the mechanical advantage is the relationship that exists between the output force or load lifted and the value of the force applied.
Thus, using the definition, we have that the mechanical advantage is given by:
Therefore, the mechanical advantage of lifting the box by using a pulley is equal to 1.
Answer:
The mechanical advantage in this situation is:
Equal to 1
