Henry will lift 200 N load 20 m up a ladder in 40 s. While the Ricardo will take 400 N load in 80 seconds. So, For Henry to take 400 N load it will take him 80 seconds in two attempts. And,also, he will have to cover 40 m of distance.
Answer:
The time constants 30 seconds and the can form an RC Charging circuit.
Explanation:
Time constant, τ, is measured in terms of τ = R x C, in seconds, where R is the value of the resistor in ohms and C is the value of the capacitor in Farads
If R = 150 kΩ = 150000Ω
and C = 200 μF = 0.0002 F
τ = 150,000 × 0.0002
<u>= 30 seconds.</u>
A capacitor, (C) connected in series with a resistor, (R) forms a RC Charging Circuit connected across a DC battery supply (Vs) via a mechanical switch, with transient time (time required to charge capacitor) = 5τ
The correct answer is letter D. A study area. <span>According to the information in your study unit, the location that requires the highest illuminance is the study room because it is the place the students can stay to study. The more brighter the place is, the more people are using that area.</span>
Answer:
Speed = 2.4 m/s
Explanation:
As given in question,
Frequency of the wave = 4 Hz
The wavelength of the wave = 60 cm
As we know,
1 cm = 0.01 m
=>60 cm = 0.6 m
So, the wavelength of the wave = 0.6 m
speed of wave = wavelength x frequency
= 0.6 m x 4 Hz
= 2.4 m/s
Hence, the velocity of wave vibrating with 4 Hz frequency and wavelength of 60 cm is 2.4 m/s.
