Answer:
The correct option is b
Explanation:
From the question we are told that
The resistance of the first resistor is 
The resistance of the second resistor is 
The capacitive reactance of the first capacitor is 
The capacitive reactance of the first capacitor is 
Generally given that the resistors are connected in parallel , their equivalent resistance is
=> 
=> 
Generally given that the capacitors are connected in parallel , their equivalent capacitive reactance is
=> 
=> 
Hence the impedance of the circuit is
=> 
Generally from the impedance equation , the total used resistance is
To find how long it will take for the trip divide miles by the speed.
605 / 55 = 11
So it will take 11 hours to get to the destination.

Answer:
3.6×10⁶ m
Explanation:
Newton's law of universal gravitation states that the force between two masses is:
F = GMm / r²
where G is the universal constant of gravitation (6.67×10⁻¹¹ m³/kg/s²),
M is the mass of one object
m is the mass of the other object,
and r is the distance between the center of masses of the objects.
The force acting on the meteor is:
∑F = ma
GMm / r² = ma
GM / r² = a
Given M = 6×10²⁴ kg and a = 4 m/s²:
(6.67×10⁻¹¹ m³/kg/s²) (6×10²⁴ kg) / r² = 4 m/s²
r = 10⁷ m
The distance from the meteor to the center of the Earth is 10⁷ m. We want to know what the height of the meteor is (distance to the surface of the Earth). So we need to subtract the Earth's radius.
h = 10⁷ m − 6.4×10⁶ m
h = 3.6×10⁶ m
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
