Answer:
400 N
Explanation:
Change of Kinetic Energy to Friction Wok
∆KE = W
½ x m x (v(5)² - v(3)²) = f x d
½ x 500 x (5² - 3²) = f x 10
250 x (25 - 9) = f x 10
25 x 16 = f
f = 400 N
Answer:
X Component is 183.85N
Explanation:
The x component of the force on the block due to the rope;
X = F cos @ where if is the force, @ is the angle mad with the block.
X = F cos @
X = 240 cos 40
Cos 40= 0.7660, so
X = 240 × 0.7660
X component= 183.85N// rounded to two decimal places.
Responder:
50A
Explicación:
Dado que el Um chuveiro y el microondas están conectados en paralelo, el mismo voltaje fluirá a través de ellos.
La potencia total consumida por ambos aparatos = 4800W + 1200W
La potencia total consumida por ambos aparatos = 6000W
Para obtener el I actual, usaremos la fórmula;
P = IV
6000 = 120I
Yo = 6000/120
Yo = 50 A
Por lo tanto, la medición de corriente del amperímetro ideal A será 50A
The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
