Answer:
increases and decreases
Explanation:
the sunspot cycle is a period of time which varies from as short as nine years to as long as fourteen years where the number of sun spots on the sun increases at the beginning of the cycle and then decreases again towards the end of the cycle.
The options of the given are:
A. A large diameter myelinated fiber
B. A small diameter myelinated fiber
C. A large unmyelinated fiber
D. A small unmyelinated fiber
E. A small fiber with multiple Schwann cells
Answer: Option A, A large diameter myelinated fiber.
Explanation:
The conduction of the nerve impulse would be greatest in the myelinated fiber because the main function of the myelin sheath is to increase the speed of the impulse at which the electrical signals propagate.
In case of the unmyelinated sheath the nerve impulse travels slowly as the conduction waves but in case of the large diameter myelinated sheath the signals travel via saltatory conduction( hop)
In this type of propagation the signals are transferred from the node of Ranvier in one neuron to next node which increases the overall velocity of the action potentials.
1. U = Q + W
U = -500 + 1000
U = 500 J
2. The first law of thermodynamic is about the law of conservation of energy where energy in should be equal to energy out.
3. It is the windmill that does not transform energy from heat to mechanical instead it is the transforms the opposite.
4. In a heat engine, work is used to transfer thermal energy from a hot reservoir to a cold one.
5. 5.00 × 10^4 J - 2.00 × 10^4 J = 3.00 × 10^4 J
6. To increase the work done, we raise the temperature of the cold reservoir.
Answer:
Explanation:
Given that
Length= 2L
Linear charge density=λ
Distance= d
K=1/(4πε)
The electric field at point P
So
Now by integrating above equation
