Answer:
however your doing it now?? ?? lol
Answer:
Part a)
at t = 3.00 s
at t = 20.0 s
Part b)
at t = 3.00 s
at t = 20.0 s
Explanation:
The car starts at x = 0
Part a)
Now at t = 3.00 s
the position of the car is given as x = 25 m and its speed is given as v = 11 m/s
Now for average velocity we have
Now for average acceleration we have
Part b)
Now at t = 20.0 s
the position of the car is given as x = 385 m and its speed is given as v = 45 m/s
Now for average velocity we have
Now for average acceleration we have
Electromagnetic Spectrum?
I think it’s A sorry if wrong
Answer:
The independent variable: is the amount of compost applied to each plant
The dependent variable: the height of the plants
Hypothesis: Older grass compost will produce taller plants
Three groups were created:
the control group is group C to which no compost was applied
investigated group A and B with different amounts of compost applied
Explanation:
The students are considering using the scientific method to analyze the problem.
The independent variable is the one controlled by the researcher and the dependent variable is the response of the system
The independent variable: is the amount of compost applied to each plant
The dependent variable: the height of the plants
Hypothesis: Older grass compost will produce taller plants
Three groups were created:
the control group is group C to which no compost was applied
investigated group A and B with different amounts of compost applied
