4095km
Explanation:
Given parameters:
Starting time = 7 o'clock
Stopping time = 11hrs 30min
Speed = 910km/hr
Unknown:
Distance covered = ?
Solution:
Speed is the rate of change of distance with time.
It is a scalar quantity that is with respect with magnitude but no direction.
Speed = 
Distance = Speed x time
Time taken = time between 11hrs 30min and 7 o'clock = 4.5hrs
Input the parameters:
Distance = 910km/hr x 4.5hrs = 4095km

Explanation:
Answer:
0.13451 m
0.124196 m
0.119997901132 m
Explanation:
= Velocity of the observer
= Velocity of sound source
v = Velocity of sound in air = 343 m/s
Wavelength is given by
The wavelength is 0.13451 m
From Doppler effect we have the formula
The wavelength is 0.124196 m
The wavelength is 0.119997901132 m
Answer:
The initial current in the circuit is 0.1873 mA
Explanation:
Given;
capacitance is given as 3.67 x 10⁻⁶ F
resistance is given as 8010 Ω
voltage across the circuit is 1.5 V
Since the capacitor is initially uncharged, the capacitive reactance is zero.
From ohms law;
Voltage across the circuit is directly proportional to the opposition to the flow of current.
V = IR
I = V/R
I = 1.5/8010
I = 0.0001873 A = 0.1873 mA
Therefore, the initial current in the circuit is 0.1873 mA
