Answer:
The frequency of watering
Explanation:
The manipulated variable in this case is the frequency of adding water to the experimental plants.
While the first plant can be said to have a watering frequency of a day, the second had a watering frequency of 2 days while the third plant had a watering frequency of 3 days.
The experiment must have been set up to determine the effects of frequency of watering on the growth of tomato plants.
The density of the metal can be determined through the formula [n*MW]/ Na*[a^3] . substituting, we get,
<span>d = [n*MW]/ Na*[a^3]
</span><span>d = [4 atoms*42.3 g/mol]/ [6.022 x 1023atoms/mol* (sqrt 8 *1.20x10-10)^3]
</span>d = 0.719 g/cm3

Answer:
Explanation:
Conservation of angular momentum
The MGR originally has momentum
L = 100(3.0) = 300 kg•m²/s²
The child can be thought of as a point mass with I = mr²
When she jumps onto the rim of the MGR
300 = (100 + 22(2.0²)ω
ω = 300 / 188 = 1.5957... 1.6 rad/s
As she moves toward the center of the MGR, her moment of inertia goes to zero as her radius goes to zero.
The angular velocity when she reaches the center will again be 3.0 rad/s
