Answer:
the responding variable is the water boiling
Explanation:
a responding variable is the same thing as a dependent variable and an independent variable you change the independent variable is the amount of salt, the control group is how long water takes to boil without adding salt, and a constant is the same amount of water
WITHOUT air resistance . . . like on the moon, or in a tank with all
the air removed from it . . . a feather, an orange, and a watermelon
will all fall at the same rate.
So will a piece of tissue, a mosquito, school bus, a rock, and a cruise
ship.
If you drop them all at the same time, then they will all hit the ground
at the same time.
Energy in Joules = Power in Watts * Time in seconds.
Energy = 1000 watt * 90 seconds.
Energy = 90 000 Joules.
