-- With two resistors in parallel, the total effective resistance is
the reciprocal of  (1/R₁ + 1/R₂).

1/R₁ + 1/R₂  = 1/15 + 1/40

= 8/120 + 3/120

= 11/120

So the total effective resistance is 120/11 = 10.9 ohms .

Current = (voltage) / (resistance)

= 12 / (120/11)

= (12 · 11) / 120

= 132/120  =  1.1 Amperes

A laboratory experiment produces a double-slit interference pattern on a screen. The point on the screen marked with a white dot
Alenkasestr [34]

Explanation:

Diffraction is a characteristic phenomenon for waves, and is based on their variance to find an obstacle or a crack. The diffraction and interference are inseparable phenomena, which are so harder to identify. Since diffraction is a specific type of interference.

if the point are in the order 2, and

the equation is d×senx=mL y at m=2

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upwar
Usimov [2.4K]

Answer:

a) 919 mts

b) 392 mts

Explanation:

In order to solve this, we will use the formulas of acceletared motion problems:

(1)Y=Yo+Vo*t+\frac{1}{2}*a*t^2\\(2)Vf^2=Vo^2+2*a*y

We are looking to obtain the initial velocity of the canister right after it was relased, we will use formula (2):

Vf^2=(0)^2+2*(3.10)*(240)\\Vf=38.6 m/s

we need to calculate the time the canister takes to reach the ground, we will use formula (1):

0-240m=38.6*t+\frac{1}{2}(-9.8m/s^2)*t^2\\\\-4.9*t^2+38.6*t+240=0\\t=11.9seconds

in order to know the new height of the rocket we have to use the formula (1) again:

Y=240+38.6*(11.9)+\frac{1}{2}*(3.10)*(11.9)^2\\Y=919mts

We can calulate the total distance the canister traveled before reach the ground by (2):

(0)^2=(38.6)^2+2*(-9.8)*y\\Y=76m

So the canister will go up another 76m, so the total distance will be:

Yc=Yup+Ydown+240m\\Yc=76+76+240\\Yc=392 mts

Explanation:

either C or A but A seems unlikely after multiple attempts. Although the question doesn't make it clear whether the balance is electric either way it could be wrong in someway and seems to be the most likely.

You make a capacitor by cutting the 16.0-cm-diameter bottoms out of two aluminum pie plates, separating them by 3.25 mm, and con
dalvyx [7]

Answer:

The capacitance of your capacitor is 5.476 x 10⁻⁵ μF

Explanation:

Given;

diameter of the aluminum pie plates = 16 cm = 0.16 m

separation distance, d = 3.25 mm = 0.00325 m

voltage across the parallel plates = 6 V

C = \frac{\epsilon A}{d}

where;

C is the capacitance of your capacitor

ε is the permittivity of free space = 8.85 x 10⁻¹²  (F/m)

d is separation distance

A is the area of the plate = ¹/₄ (πd²) = 0.25 (π x 0.16²) = 0.02011 m²

C = \frac{8.85*10^{-12} *0.02011}{0.00325} = 5.476 * 10^{-11} \ F = \ 5.476 * 10^{-5} \mu F

Therefore, the capacitance of your capacitor is 5.476 x 10⁻⁵ μF
