Answer:
True
Explanation:
The nucleus contains all of the mass of the atom. Almost all of the mass of the atoms is made up of protons and neutrons.
Answer:

at t = 0.001 we have

at t = 0.01

at t = infinity

Explanation:
As we know that they are in series so the voltage across all three will be sum of all individual voltages
so it is given as

now we will have

now we have

So we will have

at t = 0 we have
q = 0

also we know that
at t = 0 i = 0




so we have

at t = 0.001 we have

at t = 0.01

at t = infinity

Answer:
Avion A (10000 meters).
Explanation:
Deje que la altura de los aviones sea A y B respectivamente.
Dados los siguientes datos;
Altura A = 10000 metros
Altura B = 33300 pies
Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.
Conversión:
Metros a centímetros;
1 metro = 100 cm
10000 metros = 100 * 10000 = 1.000.000 centímetros.
Por lo tanto, la altura A en cm = 1,000,000 centímetros
Pies a centímetros;
1 pie = 30,48 centímetros
33300 pies = 33300 * 30,48 = 1014984 centímetros.
Por lo tanto, la altura B en cm = 1014984 centímetros.
De los cálculos anteriores, podemos deducir que el avión A voló más alto.
Answer:
The velocity of the police car is, v = 17.798 m/s
Explanation:
Given data,
The actual frequency of the siren, f = 2010 Hz
The observed frequency of siren is, f' = 2120 Hz
The velocity of the observer, v' = 0 m/s
The velocity of the source, v = ?
The formula for Doppler effect,

Where,
V - velocity of sound waves in air.

Substituting the given values,

v = 17.798 m/s
Hence, the velocity of the police car is, v = 17.798 m/s
