Material from (A.) Flare can reach the Earth causing radio blackouts. Solar flares are sudden, rapid and intense variation in brightness that is seen on the sun. It occurs when magnetic energy that has built up in the solar atmosphere, then suddenly released.
Here, we are required to determine the reaction of the power given to a circuit supplied with a constant voltage as the distance of the circuit decreases.
- In a circuit supposed with a <em>constant voltage</em>, as the resistance of the circuit decreases, the power given to the circuit Increases as evident in the formular: P = V²/R
The power given to a circuit is given by the formula;
Power, P = V × I
where, V = voltage supplied
and I = Current through the circuit.
However, from Ohm's law;
V = I × R
In essence, I = V/R
By substituting, I = V/R into the equation P = V × I
Therefore, we have;
P = V²/R.
Ultimately, if the circuit is supplied with a constant voltage, As the resistance of the circuit decreases, the power given to the circuit Increases.

Oxidation is increase in oxidation number while reduction is decrease in oxidation number.Redox is change in oxidation number.
Answer:
<em>Si hay rozamiento y el valor de la fuerza de roce es 10 N</em>
Explanation:
<u>Fuerza Neta</u>
La fuerza neta sobre un cuerpo es la suma vectorial de todas las fuerzas actuantes sobre el mismo.
Si conocemos el módulo de la fuerza neta F y la masa m del cuerpo, aplicamos la segunda ley de Newton para relacionarlas con la aceleración a:
Tenemos los datos cinemáticos de la situación, según la cual el cuerpo adquiere una velocidad (desde el reposo) de 4 m/s en 5 s.
Utilizamos la fórmula:
Y despejamos la aceleración:
Podemos calcular la aceleración real que el cuerpo adquiere, producto de una fuerza efectiva igual a:
Si se está aplicando una fuerza de y solo 20 N producen movimiento, entonces se está perdiendo en rozamiento una fuerza:
Si hay rozamiento y el valor de la fuerza de roce es 10 N
Answer:
1237.5N
Explanation:
Recall that F = ma ........1
Where F is the applied force in Newton
M is the mass in kg
And a is the acceleration in meter per seconds.
F = ?
Mass = 275kg
a = 4.50 m/s^2
Substituting the values into equation 1
F = 275kg × 4.50 m/s^2
F = 1237.5N
The force exerted on them will be 1237.5N
