Answer: Their final relative velocity is -0.412 m/s.
Explanation:
According to the law of conservation,
Putting the given values into the above formula as follows.
v =
= -0.412 m/s
Thus, we can conclude that their final relative velocity is -0.412 m/s.
It will act upon a buoyant force on the magnitude of which is equal to weight of the fluid
Answer:
1. a
2. a [im iffy on this but 95% positive its this]
3. b [walking is a form of aerobics, so i would say b]
Explanation:
Answer:
A) the current in AC electricity varies in magnitude and direction.
C) the voltage in AC electricity varies in magnitude and direction.
Explanation:
In DC current and voltage the direction of current will not change with time and it always remains the same.
So here in DC voltage and DC current the magnitude may change with time but the direction will always remain same
While in AC voltage and AC current the direction of AC will change with time
periodically.
So here magnitude and direction both will change in AC current and AC voltage.
so the correct answer is
A) the current in AC electricity varies in magnitude and direction.
C) the voltage in AC electricity varies in magnitude and direction.
