Answer:
Resistencia = 12.5 Ohmios
Explanation:
Dados los siguientes parámetros;
Voltaje = 3.5 Volts
Corriente = 0.28 Amps
Para encontrar el resistencia;
La ley de Ohm establece que a temperatura constante, la corriente que fluye en un circuito eléctrico es directamente proporcional al voltaje aplicado en los dos puntos e inversamente proporcional a la resistencia en el circuito eléctrico.
Matemáticamente, La ley de Ohm viene dada por la fórmula;
Voltaje = corriente * resistencia
Resistencia = voltaje/corriente
Resistencia = 3.5/0.28
Resistencia = 12.5 Ohmios
Por tanto, la resistencia del filamento de una linterna de bolsillo es de 12,5 ohmios.
Answer:
U = 56877.4 J
Explanation:
The potential energy of a body is that which it possesses because it is located at a certain height above the surface of the earth and can be calculated using the following formula:
U = mgh Formula (1)
Where:
U is the potential energy in Joules (J)
m is the mass of the body in kilograms (kg)
g is the acceleration due to gravity (m/s²)
h is the height at which the body is found from the surface of the earth in meters (m)
Data
m= 81.4 kg
g= 9.8 m/s²
h = 71.3 m
Potential energy of Sean and the parachute at the top of the tower
We replace data in the formula (1)
U = m*g*h
U = (81.4 kg)*(9.8 m/s²)*(71.3 m)
U = 56877.4 N*m
U = 56877.4 J
Explanation:
if the elevator is moving upward with the constant speed the spring scale will read 18 N which is the mass of each of the two blocks attached by separate springs to the scale at opposite ends.
Answer:
it is 27 degree.
Explanation:
because angle of reflection is equal to angle of Inc dence
Except when necessary for takeoff and landing, <span>the minimum safe altitude required for a pilot to operate an aircraft over other than congested area is an altitude of 1000 ft above the highest obstacle within a 2000 ft horizontal radius of the aircraft.
It is also good to know that apart from taking off and landing, the aircraft must not operate at a distance less than 500 ft from any person, vessel, structure or vehicle.</span>
