During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze.
Answer: degrees divided by 360
Explanation:
Answer:
The surface charge density on planes A and B respectively is
and
Explanation:
From the question we are told that
The electric field in region to the left of A is
The direction of the electric field is left
The electric field in the region to the right of B is
The direction of the electric field is right
The electric field in the region between the two planes is
The direction of the electric field is right
Let the surface charge density on planes A and B be represented as
From the question we see that
Generally the electric to the right and to the left is due to the combined electric field generated by plane A and B so
=>
Generally the electric field at the middle of the plane A and B is due to the diffencence in electric field generated by plane A and B
i.e
=>
=>
From equation 1
=>
So
=>
Answer:
B) the aluminum
Explanation:
The density of an object is proportional to its mass and inversely proportional to its volume. Since lead is denser than aluminum and both pieces have the same mass, then the aluminum piece has a larger volume and due to this, it will also displace more fluid. The buoyant force is proportional to the volume of the displaced fluid. Therefore, the buoyant force on aluminum is greater.
Since you didn't tell us the choices, I can pick anything I like.
The one that always does it for me is " foaming brine " .
