Answer:
C. yellow
Explanation:
The stars have different color depending on their temperature, in general the more blue or violet a star is, the higher its surface temperature, and the more orange or red, the lower its surface temperature.
In the stellar classification, stars with temperatures ranging from 5000K to 6000K are G type stars which are characterized by having a yellow color.
An example of a G-type star is the sun, which has a surface temperature of around 5700K.

The net force acting on the water skier, calculated using Newton's second law (F=ma), is approximately 111 Newtons.
The net force acting on the water skier can be calculated using Newton's second law, which states that force equals mass times acceleration (F=ma). In this instance, the skier's mass (m) is 79.0 kg and his acceleration (a) is 1.40 m/s2.
By multiplying these values together (F = 79.0 kg * 1.40 m/s2), we find that the net force acting on him is 110.6 Newtons (N). However, this exact value is not listed in the answer choices. Among the given choices, 111 N would be the closest approximation to the calculated value.

Answer:
D) When you increase the distance over which effort is expended, you don't have to work as hard.
Explanation:
This statement reflects one of the principles of mechanical advantage. When you increase the distance over which effort is applied (in situations like using a lever or a simple machine), it allows you to achieve the same work with less force. It's the concept of trading off force for distance, which is a fundamental principle in physics and mechanics.
The strength of electric field depends on the distance from the charge and also the distance between the electric field lines. If the electric field lines are closer to each other, the electric field is strong there. closer the electric field lines to each other in a region, stronger is the electric field. Electric field lines are closest in region Y. hence the electric field is strongest in region Y.
So correct choice is
3) Y
The electric field strength at a given point is determined by how densely the lines on a diagram represent it. The denser the lines, the stronger the field. Therefore, the field strength is strongest where the lines are most closely packed.
The electric field strength at a given point in space is determined by how close the point is to the charge source and the quantity of the charge. In diagrams, the electric field strength is represented by the density of the lines - in other words, the area with the most lines is where the electric field strength is strongest. Based on this principle, if we are to choose between points W, X, Y, and Z, the electric field is strongest at the point where the lines are most densely packed.
