A circuit consists of three resistors and a 3.50 V battery. Two of the resistors have known resistances of 5 Ω and 10 Ω respectively. The third resistor has an unknown resistance. When the battery is connected to the circuit, the current running through the battery is measured to be 10 A.
a. Calculate the resistance of the unknown resistor.
b. Draw the circuit and label each component.
The resistance of the unknown resistor is determined as 0.39 ohms.
Equivalent resistance of the circuitThe total resistance of the circuit is calculated as follows;
V = IR
R = V/I
R = (3.5)/10
R = 0.35 ohms
The resistors are in parallel arrangement
1/R = 1/R₁ + 1/R₂ + 1/R₃
1/0.35 = 1/5 + 1/10 + 1/R₃
100/35 = 3/10 + 1/R₃
20/7 = 3/10 + 1/R₃
1/R₃ = 20/7 - 3/10

Hi,i need this hurry and correctly please!!!,fake answers i report you.Thanks.
Step-by-step explanation:
Step 1: Formula
10.0 = Meters
800 = Newtons
4.0 = Centre of Gravity
Explanation in words (Short Form)
- We know all the formulas and that we are calculating the least force being applied. We know that balancing the pole at (A) with the weight of the gravity will equal more force at B times 10. So the answer will be 320 N because the B force will equal 3200. If we divide 3200 by 10. The answer will result as 320. So the final answer for this question is 320N
Answer:
Balancing the pole at A with the weight acting at the centre of gravity = 800(4) Force at B multiplied by 10 = 3200 divided by 10 equals 320N
= 320N

Anyone able to help with this one? The volume of a gas sample is 550 mL and the pressure is 1.8 atm. What will the new volume of the gas be if the pressure increases to 2.2 atm? Round your answer to the correct number of significant figures.
Answer:
450 ML
Explanation:
Given:
Volume of gas sample: 550 mL Pressure: 1.8 atm plus 2.2 atm
To find:
The new volume of the gas after the pressure increases to 2.2 atm.
___
steps
⇒ [tex]V_1P_1=V_2P_2[/tex]
⇒ [tex](550\text{ml})(1.8\text{atm})[/tex]
⇒ [tex]=(x)(2.2\text{atm})[/tex]
⇒ [tex]x=\frac{(550)(1.8)}{2.2}[/tex]
⇒ [tex]x=450\text{ml}[/tex]
Answer:
V₂ = 450 mL
Explanation:
Because you are dealing solely with pressure and volume, you can use Boyle's Law to find the missing value. The equation looks like this:
P₁V₁ = P₂V₂
In this formula, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You have been given values for all of the variables except for "V₂". Thus, you can substitute the given values into the equation and simplify to find the answer. The final answer should have 2 sig figs to match the given values.
P₁ = 1.8 atm V₁ = 550 mL
P₂ = 2.2 atm V₂ = ?
P₁V₁ = P₂V₂ <----- Boyle's Law equation
(1.8 atm)(550 mL) = (2.2 atm)V₂ <----- Plug given values in
990 = (2.2 atm)V₂ <----- Multiply 1.8 and 550
450 = V₂ <----- Divide both sides by 2.2

The magnitude of the acceleration that the engine must produce is 0.065 m/s².
What is acceleration?Acceleration is given by the ratio of Resultant or total force acting on any object and the its mass.
It can also be defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Given is a lunar probe is moving 1670 m/s at a 73° angle. it needs to land on the moon 3.71 x 10⁸ m away in a 46° direction in 8.64 x 10⁴ s.
The initial velocity will be
1670 x cos (73°-46°) = 1487.981 m/s
Using the second equation of motion, we have
s = ut + 1/2 at²
The final velocity will be zero after landing on Moon.
Substituting the values, we have
3.71 x 10⁸= 1487.981 x 8.64 x 10⁴ + 1/2 a ( 8.64 x 10⁴)²

The distance between two adjacent nodes of a standing wave is equal to one-half (that is, [tex](1/2)[/tex]) the wavelength of this wave.
Let [tex]\lambda[/tex] denote the wavelength of the standing wave in this question. The distance between two nodes of this wave is [tex]0.25\; {\rm m}[/tex], meaning that [tex](1/2)\, \lambda = 0.25\; {\rm m}[/tex]. Thus, [tex]\lambda = 2 \times 0.25\; {\rm m} = 0.50\; {\rm m}[/tex].
