Momentum equation is
change in momentum = mass•initial velocity•final velocity
so....
p=700(15) because your initial is 30, and your final in 15, so you subtract! hope that helped!
Answer:
3. 560W
Explanation:
First we calculate the work required for the 700N weigh student to climb up by 8 meters. Work is force times distance
W = Fs = 700 * 8 = 5600J
The average power is defined as the rate of energy expended over a unit of time. In order words, work divided by time duration
P = W/t = 5600 / 10 = 560 W
The result that should be established is in the form
y = f(x)
where x, the amount of sunlight is the controlled (independent) variable,
y = height (growth) that corresponds to the amount of sunlight. Therefore y depends on x.
Clearly,
x, the amount of sunlight is the independent variable. It can be controlled.
y, the measured amount of growth is the dependent variable.
Answer:
The independent variable is the amount of sunlight.
The dependent variable is the growth.
The answer is 34 you have to add the numbers and divide them by how many numbers there are
