the resistance is 80.8Ω and average power 178.2 W
a) the value of resistance is given as,
R=rms voltage / rms current
and rms current = 2.1/√2
= I°/√2
rms current = 2.1/√2
rms current = 1.48
therefore R = 120/1.48
=80.4Ω
b) average power is product of rms current and rms voltage
P=120× 1.48
=178.2 W

7) p=w/t
2620/0.2
=13100W
8) W=pt
40*30
=1200 J
9) transformed
A) atomic number 7
B) 15
C) 6 c, 12 h, 6 o
D) o-8
S-16
Density =Mass/volume
When mass is constant, density is inversely proportional to volume or vice versa
When volume decreases, density increases
Hope it helps
Answer:
The answer to this question is acceleration or as scientist say velocity.
Explanation: We know that when you drive a car the acceleration is effected by the amount of speed you add when you press the gas,so you are accelerating the car faster.
