Sunspots<span> are temporary phenomena on the </span>Sun<span>'s photosphere that appear as </span>spots<span> darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. </span>Sunspots<span> usually appear in pairs of opposite magnetic polarity.

Answer:
D) ¼ as large
Explanation:
The magnitude of the electric force between two charges is
where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the separation between them
From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.
In this problem, the distance is doubled:
So the new force will be
So the force will decrease to 1/4 of its original value.
Answer:
Check Explanation.
Explanation:
(1). The force that will continue to move the sled toward the right and speeding up at steady rate(constant acceleration) = option C => The force is toward the right and is constant strength (magnitude).
(2). The force that will continue to move the sled toward the right and at Constant velocity = option G => No applied force is needed. This is because acceleration = 0,and force is also = 0.
(3). The force that will continue to move at steady rate and an acceleration to the right = option A => The force is toward the right and is decreasing in strength (magnitude).
(4). The force that will slow the sled moving to the right at steady rate(constant acceleration) = option F => The force is toward the left and is of constant strength (magnitude).
(5). The force that moves the sled rest toward the a steady (velocity) towards the left = option G => No applied force is needed.
Answer:
This has been explained below.
Explanation:
Sound waves move along the auditory canal and when moving they hit the tympanic membrane making it to vibrate. this vibration would make the 3 ossicles to move. the tympanic membrane is sticked to the auditory ossicles and the stapes are joined to the oval window. as movements occur in the oval window, there would be motions happening in the cochlea
