Answer:
The time is 176 seconds
Explanation:
We use the formula:
V= d/t V=velocity, d= distance, t= time
259 m/s= 45683 m/ t
t= 45683 m// 259 m/s
t= 176, 3 seg
R:<span> </span><span>If they give you the net torque and the moment of inertia already, it's pretty easy.
torque = I * alpha, where I is moment of inertia, alpha is angular acceleration.
Thus, 0.098 / 0.000075 = 1306.666... rad / s^2
The angular acceleration remains constant, but the angular velocity at that point (if you want it) is 21.36 rad / s</span>
The answer that you are looking for is D.
Answer:
i = 5.28 A
Explanation:
The magnetic force is given by the expression
F = i l x B
the bold letters indicate vectors, let's write the modulus of that expression, where the direction between the conductor and the magnetic field is 90º, therefore the sine 90 = 1
F = i l B
i = F / l B
let's reduce the length to the SI system
l = 10 cm (1m / 100 cm) = 0.10 m
let's calculate
i = 12.9 / 0.1 3.6
i = 5.28 A
Just carbon is a metalloid not oxygen
