Answer:
Explanation:
In a L C R circuit, the average power is given by
As given in the question
CosФ = R / Z
And we know that
So
The correct answer is '44'.
In fact, the atom of an element has an equal number of protons and electrons: therefore, if element X has 44 protons, it should have 44 electrons as well.
For curiosity: the chemical element with 44 protons and 33 electrons is Ruthenium.
Explanation:
The given statement is absolutely true. this is because magnitude of a vector is always non negative, it can not be zero unless its a zero vector. So, in the given question, final position vector of a moving object has a smaller magnitude than the initial position vector, so, magnitude is neither zero nor negative. Hence, it has a positive magnitude.
Hey there,
Your correct answer would be 30kg.
450 = m × 15 or also 450/15=m.
Hope this helps.

Answer:
a 5 kilogram mass, at a height of 3 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.
