For electrical devices . . .
Power dissipated = (voltage) x (current) =
(12 V) x (3.0 A) = 36 watts .
1 watt means 1 joule per second
(36 joule/sec) x (60 sec/min) x (10 min) = 21,600 joules
Vector quantities have both magnitude and direction. Distance is a scalar quantity. It refers only to how far an object has traveled. For example, 4 feet is a distance; it gives no information about direction.
Answer: Well first of all, for an Atom to be neutral, it shall have an equal number of the protons and the neutrons. So given that, the protons are able to be positively charged and since the electrons are negatively charged (Protons and Electrons are completely different from each other) then that means the Algebric are aggregated of charges because it equal to zero. So overall, the 'neutral atom' has to be neutral, and how? Protons must equal the number of electrons or else it wouldn't be considered neutral.
Hopefully this helps you very much!! :-) Have a great daayy!
Answer:
a = 2.44 m/s²
Explanation:
The Net force acting on the car downwards the plane will be equal to the component of the weight that is parallel to the plane.
Thus;
mg(sin θ) = ma
Thus;. g(sin θ) = a
g is acceleration due to gravity = 9.81 m/s²
θ = 14.4°
Thus;
9.81 × sin 14.4 = a
a = 2.44 m/s²
0, Because if they are pulling with equal force then they cancel each other out<span />
