That's 299,792,458 meters per second.
When the current is time-dependent, the circuit has a
capacitor. A capacitor could be used to store energy. As you use it up, the
energy depletes. This is why it is time-dependent. The answer is 12 seconds. I
hope I answered your question. Have a good day and thanks.
The correct answer is C. microwaves, infrared, visible, gamma rays
Electromagnetic waves arranged in order of frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.
Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.
According to the Einsteins equation, E=hf, Energy is directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
Answer:
V = x/t
where:
x = distance [m]
t = time [s]
V = velocity [m/s]
Explanation:
Speed is defined as the distance travelled by a body in a given time interval. The velocity or speed is a vector, that is, it has magnitude and direction.
By virtue of its vector character, the direction of the displacement and the module, which is called speed, must be considered to define the velocity.
<u>Average speed</u>
The average speed is defined as the change of position over a given time interval. It is calculated by dividing the displacement vector (Δx) between the time interval (Δt) used.
<u>Instant speed</u>
Instantaneous velocity is a vector tangent to the trajectory, corresponding to the derivative of the vector position relative to time.
It allows to know the speed of a mobile that moves on a trajectory when the interval of time is infinitely small, being then the space traveled also very small, representing a point of the trajectory. Instant velocity is always tangent to the trajectory.
The correct answer is #4. They have the same number of protons but a different number of neutrons.
