Answer:
A RCRA characteristic hazardous waste is a solid waste that exhibits at least one of four characteristics defined in 40 CFR Part 261 subpart C — ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity (D004 - D043). combustible, or have a flash point less than 60 °C (140 °F).
Answer:
a. 60V
b. 77.46V
c. 600 W
d. there would be no effect when this is done
Explanation:
a.
to get value of average output
Vo = VsD
Vs = 100V
D = 0.6
Vo = 100 V * 0.6
Vo = 60V
Therefore 60V is the value of average voltage
b.
The rms voltage:
= Vs√D
= 100 x √0.6
= 100 x 0.7746
= 77.46V
the rms voltage is Therefore 77.46V
c.
value of average power:
= (RMS)²/R
R = 10
when we put into formula above,
= (77.46)²/10
= 6000.05/10
= 600.005 W
= 600W
d.
If switching frequency is changes to be 2khz it would actually have no effect on the average voltage, average power or rms voltage.
Answer:
a) 156 meters
b) 58 m/s
c) 9.8 m/s^2
Explanation:
a) The horizontal displacement X = V *t
X = 50 * 3 = 150 meters
Vertical displacement = y = – g * t² / 2
Y = -9.8 *3*3/2 = -4.9*9 = 44.1
Net Displacement = Sqrt (X^2 +Y^2) = 156.34 = 156 meters
b) Speed of the projectile
vx = 50 m/s
vy = t*g = 9.8*3 = 29.4
V = Sqrt (vx^2 + vy^2) = 58 m/s
c) Acceleration is the acceleration due to gravity = 9.8 m/s^2
