Answer:
Gate control theory of pain
Explanation:
The gate control theory of pain sates that non-painful input closes the nerve gates to painful input, which prevents pain sensation from traveling to the central nervous system (brain).
Therefore, the idea that large fibers in the sensory nerves can prevent impulses from reaching the brain and thus prevent the sensation of pain is part of the gate control theory of pain.
Answer:
g, downward
Explanation:
It is given that, a baseball is thrown straight upward. The force acting on the stone is force of gravity. It is moving under the action of gravity. We know that the force of gravity always acts in a downward direction.
At the highest point, the velocity of the stone will be equal to 0. It will move will constant acceleration equal to g and it always acts in downward direction.
Hence, the correct option is (e) "downward direction".
I believe the answer is B: It’s moving at a constant speed.
Answer: 
electrons pass through a cross section of the wire each second.
Explanation:
According to mole concept:
1 mole of an atom contains 
number of particles.
Given : Charge on 1 electron = 
Charge on 1 mole of electrons = 
To calculate the charge passed we use the equation:
where,
I = current passed = 1 A
q = total charge = ?
t = time required = 1 sec
Putting values in above equation, we get:
When 96500C of electricity is passed , the electrons passed =
1 C of electricity is passed , the electrons passed = 
Hence, electrons pass through a cross section of the wire each second.
Answer:
430.
Explanation:
If we know that 0.5 is half of a whole number, then we can simply understand that we need to 215 x 2 to get our answer.
