The answer is A. Urinary system
the independent variable is what you're testing or changing in an experiment, so the answer is the temperature of the ball when its dropped.
i hope that helped <3
Answer:
2100 J
Explanation:
The heat required to increase the temperature of a substance is given by

where
m is the mass of the substance
C is its specific heat capacity
is its change in temperature
For the water in this problem, we have:
m = 100 g is its mass
C = 4.2 J/g • °C is the specific heat capacity
is the increase in temperature
So, the amount of heat needed is:

Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
