Answer:
0.5m
Explanation:
v=f×lamda
v is 300m/s, f is 600Hz, lamda is ?
lamda=v/f
lamda=300/600
lamda =3/6=1/2m
That's false. Both moons of Mars are tiny, and Mercury and Venus have no moons at all.
Answer:
150 J
Explanation:
Work: This can be defined as the product of force and distance. The S.I unit of work is Joules (J)
The work done in lifting the crate = Force × distance.
W = F×d .............................. Equation 1.
Where F = force, d = distance, W = work done in lifting the crate,
Given: F = 100 N, d = 1.5 m.
Substituting these values into equation 1
W = 100(1.5)
W = 150 J.
Thus the work done in lifting the crates to that height is 150 J
The total reactance of the inductor and the capacitor is 470.1 ohms.
The given parameters;
- <em>inductance of the coil, L = 250 mH</em>
- <em>capacitance, C = 4.7 μ</em>
- <em>frequency of the circuit, f = 60 Hz</em>
The inductive reactance of the coil is calculated as follows;
The capacitive reactance of the capacitor is calculated as follows;
The impedance of the circuit is calculated as follows;
Thus, the total reactance of the inductor and the capacitor is 470.1 ohms.
