In a science experiment, the dependent variable is the thing that will change based on what else is happening in the experiment. The independent variable is the thing that stays the same every time.
Answer:
123 km/h
Explanation:
The distance between the Jeep Wrangler and the Ford Taurus is increasing.
Let us consider the north direction as positive when observing from the ground
So, the south direction will be negative
But when the observer is one of the cars the direction will be the same i.e., moving away from each other, so the velocity will be added.
Hence velocity of the Jeep relative to the Ford will be
Velocity of the Jeep + Velocity of the Ford
= 74+49 = 123 km/h
∴ Velocity of the Jeep relative to an observer in the Ford is 123 km/h
Sodium (Na) is a Alkali metal so that's the answer
Answer:
Explanation:
We have given the mass of the carbon =0.1 kg
Molar mass of the carbon =12 gram
Number of moles
We know that 1 mole of carbon contain
So atoms contained by 8.333 moles
In question it is given that each atom contain 6 proton so number of proton
Now we know that each proton contain positive charge of
So total charge
The box of 15 baseballs because it has more weight.
