Answer:
80 amperes
Explanation:
Current in the circuit = ?
Voltage in the circuit = 160 Volts
Resistance = 2 Ω
Voltage = Current x Resistance
V = IR
160V = I x 2 Ω
I = 160V / 2 Ω
I = 80 Amperes
Therefore the current in the circuit is 80 amperes :)
Answer:
Stationary listener frequency = 77.68 kHz
Explanation:
Given:
Speed of airplane = 344/2 = 172 m/s
Sound of frequency = 5.84 kHz
Computation:
f0 = fs[(v+v0)/(v-vs)]
f0 = 5.84[(344+0)/(344-172)]
f0 = 5.84[(344)/172]
Stationary listener frequency = 77.68 kHz
Answer:
147 N
Explanation:
static friction = frictional force max / normal
normal force = mg = 50 kg × 9.8 m/s² = 490 N
0.3 = Frictional force / 490 N
0.3 × 490 N = 147 N
The body will not move because the frictional force is greater than the force applied.
Answer:
The lights bounces from the object behind which hit one's eyes. The glass is transparent because it does not absorb any radiation
