The real peak voltage is 120/0.707 = 170 V.
The peak voltage is the highest point or voltage value in any voltage waveform. A power quality issue arises when Pulse Width Modulation (PWM) devices, such as variable frequency drives, are added to a power system with a peak voltage equal to the square root of two times the RMS voltage. The peak voltage, for instance, if the RMS voltage is 85 V. The average voltage and maximum voltage of AC power coming from the wall are both about 110 V. Therefore, the real peak voltage is 120/0.707 = 170 V. The sinusoid's amplitude is divided in half by this. Peak-to-peak voltage (Vp-p), also known as the total amplitude, is 340 V, or twice the peak voltage.

Answer:
t = 0.11 second
The time taken to reach the maximum height of the trajectory is 0.11 second
Explanation:
Taking the vertical component of the initial velocity;
Vy = Vsin∅
Initial velocity V = 2.15 m/s
Angle ∅ = 30°
Vy = 2.15sin30 = 2.15 × 0.5
Vy = 1.075 m/s
The height of the rock at time t during the flight is;
From the equation of motion;
h(t) = Vy×t - 0.5gt^2
g= acceleration due to gravity = 9.8m/s^2
Substituting the given values;
h(t) = 1.075t - 0.5(9.8)t^2
h(t) = 1.075t - 4.9t^2
The rock is at maximum height when dh/dt = 0;
dh(t)/dt = 1.075 - 9.8t = 0
1.075 - 9.8t = 0
9.8t = 1.075
t = 1.075/9.8
t = 0.109693877551 s
t = 0.11 second
The time taken to reach the maximum height of the trajectory is 0.11 second
the velocity of the air is94.25V kg/s
Calculation :
Assuming velocity of air through spherical shell = V m/s
then flux = ρ *π *
*V kg/s
=1.2 *π *
*V = 94.25V kg/s
Rate of change of distance. Rate of change of displacement. The velocity of a moving object can never be negative.
Velocity is the directional velocity of a moving object as an indicator of the observed rate of change of position from a given reference frame.
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) versus change in time (Δt), given by the formula v = Δs/Δt.

Answer:
Explanation:
Direction of velocity of electromagnetic wave is given by the formula
E = E j ( vector form )
B = - Bi ( vector form )
Direction of velocity = direction of vector E X B
= E X B
= E j x -Bi
= - EB -k
v = EBk
So the direction of velocity will be along z direction.
