Voltage, resistance and current are the three components that must be present for a circuit to exist. A circuit will not be able to function without these three components. Voltage is the main electrical source that is present in a circuit. :)
Answer:
<h3>sound waves enter the ear canal and cause the ear drum vibrate </h3>
vibration pass through 3 connected bones in the middle ear. this motion set FUILD MOVING bends thousands of delicate hair-like cells which convert the vibrations into NERVE IMPULSES.
<span>If your vehicle sinks in water and assuming that you are the driver, you should kick out the driver's window when the pressure equalizes.
You should't waste your time trying to reach the rear window and you shouldn't break the front window. Therefore, just break the one nearest to you which is the driver's window in this case.</span>
Answer:
C. 2.0 cm
Explanation:
The magnetic field around the wire at point M is given by Biot-Savart Law:
where,
B = Magnetic field = 50 μT = 5 x 10⁻⁵ T
I = current = 5 A
μ₀ = permeability of free space = 4π x 10⁻⁷ N/A²
R = distance of point M from wire = ?
Therefore,
R = 0.02 m = 2 cm
Hence, the correct option is:
<u>C. 2.0 cm</u>
Answer:
1.10 m
Explanation:
First, find the time it takes to land.
Given, in the y direction:
Δy = 1.12 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(1.12 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.478 s
Next, find the distance traveled in that time.
Given, in the x direction:
v₀ = 2.30 m/s
a = 0 m/s²
t = 0.478 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.30 m/s) (0.478 s) + ½ (0 m/s²) (0.478 s)²
Δx = 1.10 m
