Answer:
1. R = 8 ohms 2. V = 32 volts
Step-by-step explanation:
<h3>1. We have,</h3>
Voltage, V = 16 V
Current, I = 2 A
We need to find the resistance of the circuit. Using Ohm's law,
V = IR
So,
2. Current, I = 8 A
Resistance, R = 4 ohms
We need to find the voltage of the circuit. Using Ohm's law again,
V = 8 × 4
V = 32 volts
Hence, this is the required solution.
Answer:
D) 27 liters
Step-by-step explanation:
V = 30x30x30 = 27000 cm³
1000 cm³ = 1 liter
27000 cm³ = 27 liters
Answer:
Step-by-step explanation:
x = father's age
y = son's age
Nowadays:
3x = y
5 years ago:
4(x - 5) = y - 5
4x - 20 = y - 5
4x = y + 15
I hope I've helped you.
Answer:
d.)
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
• find x
use tan rule
tan( 60 degrees) = x / 7
tan ( 60 ) x 7 = 12 . 1
x = 12. 1
• find y
you can either use Pythagoras theorem or the sin rule
let's use sin
sin ( 30 ) = 7 / y
y = 14.0
