Answer:
A hypothesis predicts the value of a dependent variable given an independent variable:
If a person weighs 50 kg (independent variable) the weight hypothesis predicts that W = 50 * 9.8 = 490 N (the dependent variable)
So those three should be present in an investigation
Answer:
Yes, they are.
Explanation:
it says it has to be 20 characters long so this is random.
All 15 patients will most likely have the same test results reguarding the ages would make the results vary

Hope this helped!!
Answer:
393.6m/s
Explanation:
Given parameters:
Acceleration = 8.5m/s²
Distance = 300m
Final velocity = 400m/s
Unknown:
Initial velocity = ?
Solution:
To solve this problem, we use the expression below;
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
So;
v² - 2as = u²
u² = v² - 2as
u² = 400² - (2 x 8.5 x 300)
u = 393.6m/s
B would be an example of vaporization (liquid to gas).
———————
A is an example of deposition (gas to solid); C is an example of condensation (gas to liquid); and D is an example of condensation, deposition, or freezing—depending on the type of cloud.
