Three resistors are connected in parallel to the voltage source with resistors R1 = 30 Ω, R2 = 150 Ω and R3 = 90 Ω. A current of

Annette [7]

Answer:

0.6 A

Explanation:

When resistors are connected in parallel,

(i) The voltage across each of the resistor is the same

(ii) The current in the circuit is equal to the sum of the current flowing through the individual resistor.

Firstly, we look for the voltage across the the R₃ resistor.

From Ohm's law,

V₃ = I₃R₃................. Equation 1

Where V₃ = Voltage across R₃, I₃ = current flowing through R₃

Given: I₃ = 200 mA = 0.2 A, R₃ = 90 Ω

Substitute into equation 1

V₃ = 0.2(90) = 18 V.

Note: V₁ = V₃ = 18 V.

Secondly, we calculate the current flowing through R₁

Using,

I₁ = V₁/R₁........................... Equation 2

Given: V₁ = 18 V, R₁ = 30 Ω

Substitute these values into equation 2

I₁ = 18/30

I₁ = 0.6 A

An Air Force plane lands with a velocity of 125 m/s and accelerates at a maximum rate of -6.5 m/s^2.

Alisiya [41]

Answer:

a) 19.2 s

b) No

Explanation:

Given:

v₀ = 125 m/s

a = -6.5 m/s²

v = 0 m/s

a) Find: t

v = at + v₀

(0 m/s) = (-6.5 m/s²) t + (125 m/s)

t ≈ 19.2 s

b) Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (125 m/s)² + 2 (-6.5 m/s²) Δx

Δx ≈ 1200 m

My homework says-

Amanda [17]

And I gather that instead of trying it on your own, you want me to do it for you.

The force of gravity between two objects always involves the product of
both of their masses.

"Weight" is the force of gravity between a planet and an object on its surface,
so it depends on both masses.

When a rock, a space probe, or an astronaut goes to a different planet, its/his
mass doesn't change, but the mass of the body they're standing on is different.
So the weight of the rock or the astronaut is different from what it is on Earth.
