Answer:
The image height is 3.0 cm
Explanation:
Given;
object distance, 
= 15.0 cm
image distance, 
= 5.0 cm
height of the object, 
= 9.0 cm
height of the image, 
= ?
Apply lens equation;
Therefore, the image height is 3.0 cm. The negative values for image height indicate that the image is an inverted image.
Options are. Zenith, Great circle, Equinox, or Meridan
Answer:
c. vf is greator than v2, but less than v1
Explanation:
The principle of conservation of linear momentum states that when two or more bodies act upon one another, their total momentum remains constant.
In a system of colliding bodies the total momentum of the system just before the collision is the same as the total momentum just after the collision.
Collisions in which the kinetic energy is conserved are called elastic collision.
Collisions in which the kinetic energy is not conserved are called inelastic collisions. If the two objects stick together after the collision and move with a common velocity, the collision is said to be perfectly inelastic.
<em>The above scenario is a perfectly inelastic collision. The initial velocity of particle 1 was greater than particle 2 before collision. After collision, its velocity will reduce to a final velocity vf as it transfers some of its kinetic energy to particle 2; whereas, the velocity of particle 2 will increase to a final velocity vf as it absorbs some of the kinetic energy of particle 1.</em>
Therefore,
a. vf = v2 is wrong because vf is greater than v2
b. vf is less than v2 is wrong because vf is greater than v2
c. vf is greater than v2, but less than v1 is correct.
d. vf = v1 is wrong because vf is less than v1
The answer would be a speed
The concept that we need here to give a proper solution is mutual inductance.
The mutual inductance is given by the expression
Where,
I = current
N = Number of turns
Flux through the solenoid.
Part A) Then we have in our values that,
Replacing in the equation,
Part B) Here is required the Flux, then using the same expression we have that
We conserve the same value for the Inductance but now we have a current of 2.6, then
Therefore the flux in Solenoid 1 is
