Answer:
70 m/s.
Explanation:
because the vertical velocity component of 30 m/s was initial horizontal velocity of 40 m/s was maximum height.
<u>Answer</u>
<span>C. It will move back and forth between a large positive and a large negative value.</span>
<u>Explanation</u>
The generator in the diagram produces an alternating current. This means the direction of the current every time the generator rotates. The current produced is large.
The needle will move back and forth in every rotation.
Answer:
ΔV = 20.1 V
Explanation:
As the positive plates are connected to each other, the capacitors are connected in parallel, so the total system load is the sum of the charges on each capacitor.
Q = Q₁ + Q₂
The charge on each capacitor is
Q₁ = C₁ ΔV₁
Q₁ = 24 10⁻⁶ 25
Q₁ = 6.00 10⁻⁴ C
Q₂ = C₂ ΔV₂
Q₂ = 13 10⁻⁶ 11
Q₂ = 1.43 10⁻⁴ C
The total set charge is
Q = (6 + 1.43) 10⁻⁴
Q = 7.43 10⁻⁴ C
The equivalent capacitance is
C_eq = C₁ + C₂
C_eq = (24 + 13) 10⁻⁶
C_eq = 37 10⁻⁶ F
Let's use the relationship to find the voltage
Q = C_eq ΔV
ΔV = Q / C_eq
ΔV = 7.43 10⁻⁴ / 37 10⁻⁶
ΔV = 2.008 10¹
ΔV = 20.1 V
This voltage is constant in the combination so it is also the voltage in capacitor C1
Answer:
By energy efficient, if you mean LED, no the lamp will not flow like normal. If the bulb is still an incandescent but slightly lower wattage, it will take a little longer to get going. Lava lamps require heat and light for the effect to work.
