Answer:
Explanation:
Initial is all kinetic energy
final is all potential energy (spring)
½kx² = ½mv²
x = √(mv²/k) = √(1.3(2.8²) / 800) = 0.01274 m or about 1.3 cm
L = L₀ - x = 0.439 - 0.013 = 0.426 m
F = kx = 800(0.01274) = 10.192 or about 10.2 N
Answer:
4 A
Explanation:
Firstly we need to calculate the equivalent resistance. Since, two resistors of 6 connected in parallel, so equivalent resistance will be given by,
1/R = 1/R1 + 1/R2
1/R = (1/6 + 1/6) Ω
1/R = (1 + 1)/6 Ω
1/R = 2/6 Ω
R = 6/2 Ω
<u>R = 3 Ω</u>
We know that,
V = IR
- <em>V</em> denotes p.d (12V)
- <em>I</em> denotes current
- <em>R</em> denotes resistance (3 Ω)
12 = I × 3
12 ÷ 3 = I
<u>4 Ampere = I</u>
Answer:
False
