Answer:
Explanation:
340 m/s / 968 cyc/s = 0.3512396... ≈ 35.1 cm
First question:
The magnitude of current flowing in a circuit is described in
units of Amperes. The device used to measure it is an Ampmeter,
or Ammeter.
Second question:
This question is so absurd that it should not be dignified with an
answer. Although 'E' is often used as the symbol for Electromotive
force, potential difference, and voltage, there's certainly no rule.
Anyone is free to use 'M', 'Q', 'Θ', or 'Щ' to denote voltage when
they write electrical formulas, just as long as they make sure to
explain the meaning of whatever symbols they use.
Answer:
Explanation:
The "traditional" form of Coulomb's law, explicitly the force between two point charges. To establish a similar relationship, you can use the integral form for a continuous charge distribution and calculate the field strength at a given point.
In the case of moving charges, we are in presence of a current, which generates magnetic effects that in turn exert force on moving charges, therefore, no longer can consider only the electrostatic force.
Answer:
The square of the hypotenuse is equal to the sum of the squares of the other two lengths.
Explanation:
only one that made sense
Answer:
A, C and D
Explanation:
The impulse is defined as the product between the force (F) and the time of the collision (t):
Let's apply the formula to calculate the impulse for each situation:
A) 
B) 
C) 
D) 
We see that the situations in which the impulse is equal to 10 units are:
A, C and D
