Answer:
it's ii) R is correct while A is incorrect
Explanation:
cuz, both statements are correct but the reason is not the correct reason for the assertion,
The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)
To solve this problem it is necessary to apply the concepts related to the Moment. The moment in terms of the Force and the time can be expressed as

F = Force

At the same time the moment can be expressed in terms of mass and velocity, mathematically it can be given as

Where
m = Mass
Change in velocity
Our values are given as

By equating the two equations we can find the Force,



Therefore, the net average force will be:

The negative symbol indicates that the direction of the force is upwards.
Answer:
The answer to your question is Equation vf = gt; vf = 29.6 m/s
Explanation:
Data
gravity = 3.7 m/s²
vf = ?
time = t = 8 s
Formula
vf = vo + gt
Initial speed = 0 m/s
To solve this problem we can use the equations of free fall and just substitute the data.
- Substitution
vf = 0 + (3.7)(8)
- Simplification
vf = 29.6 m/s
Answer:
Photon
Explanation:
Electrons don't weigh very much at all, and don't account for the chemical mass of an element. However, Photons don't have ANY mass.
