Answer:
Should place the current perpendicular to the magnetic field
Explanation:
The magnetic force exerted on a current-carrying wire is given by
where
I is the current in the wire
L is the length of the wire
B is the magnetic field
is the angle between the direction of the wire and the magnetic field
As we see from the formula, the magnetic force is maximum when
which means
So, when the current in the wire and the magnetic field are perpendicular to each other.
The Greeks thought that the sun was the center of the Univesre for plantets like earth to observe it !!!
Answer:
The answer would be the last option (the one with the arrow pointing sideways)
Explanation:
The arrow lost it's acceleration and is starting to go downwards but it isn't a straight slope down
Answer:
20 rad/s^{2}
Explanation:
weight / force (F) = 150 N
radius (r) = 0.5 m
mass (m) = 15 kg
angular acceleration = tangential acceleration / radius
where
- tangential acceleration = force/ mass = 150/15 = 10 m/s^{2}
- substituting the above into the equation for angular acceleration we have
angular acceleration = 10 / 0.5 =
