So to find R (resistance) you do ohm's law E (volts) over I (current) to find R
So this is 12/30 = 0.4 so the resistance is 0.4
Answer:
10 kg
Explanation:
The mass of an object does not change even if the amount of gravtiy changes.
Answer:
a. El peso = 686 Newton
b. El peso = 113.4 Newton
Explanation:
Dados los siguientes datos;
Masa = 70 kg
Aceleración debida a la gravedad en la luna = 1,62 m/s² una.
a. Para encontrar la fuerza-peso en la Tierra;
Sabemos que la aceleración debida a la gravedad es igual a 9,8 m/s² en el planeta Tierra.
El peso se puede definir como la fuerza que actúa sobre un cuerpo o un objeto como resultado de la gravedad.
Matemáticamente, el peso de un objeto viene dado por la fórmula;
Dónde;
m es la masa del objeto.
g es la aceleración debida a la gravedad.
Substituting into the formula, we have;
El peso = 70 * 9.8
El peso = 686 Newton
b. To find weight on moon;
Weight = mass * acceleration due to gravity on moon
Weight = 70 * 1.62
Weight = 113.4 Newton
Answer:
Air pressure decreases as altitude increases.
Explanation:
Answer:
The speed of the wave as it travelled through the brass bell is;
B. 4,700 m/s
Explanation:
The given parameters are;
The wavelength of the sound wave produced from the brass bell,
= 3.5 m
The wavelength of the wave in the brass bell,
= 47 m
The frequency of the wave in the brass bell, f = 100 Hz
The given equation for wave speed, v = f × λ
Therefore, the speed of the wave as it travelled through the brass bell,
, is given as follows;
= f ×
= 100 Hz × 47 m = 4,700 m/s
The speed of the wave as it travelled through the brass bell =
= 4,700 m/s
