Because acceleration is not speed, and speed is not acceleration.
I'm sure you would not ask "Why isn't temperature given in acres,
as it is for area ?" Speed and acceleration are different things, so
it's only natural that they have different units.
The magnitude (size) part of acceleration is:
(how much speed changes) per second.
Are you speeding up ?
Are you traveling (2 meters per second) faster every second ?
Then your acceleration is
(2 meters per second) per second .
When you write that phrase as an algebraic expression, it's
(2 m/sec) / sec
and when you simplify that fraction, you get 2 m/sec² .
Answer:
The energy stored in the capacitor is 333.3 J
Explanation:
Energy stored in a capacitor = CV²/2
C = capacitance = 14 × 10⁻⁶F
V = 6.90 × 10³V
Energy = (14 × 10⁻⁶)(6.90 × 10³)²/2 = 333.27 = 333.3 J
Hope this Helps!!!
Answer:
A. The nucleus can be either positively charged or neutral.
Explanation:
The nucleus of an atom contains protons and neutrons only. Whereas electrons revolve around the nucleus. Protons are positively charged, neutrons have no charge and electrons are negatively charged.
