What are the Differences between ancient and modern astronomy?
Answer:
ancient astronomy is back in the 1600s and is really old and modern astronomy is present and astronomy today
Time period and technology are the main differences between ancient and modern astronomy.
The main differences between ancient and modern astronomy is the era in which they were created and developed. The ancient astronomy developed by Greeks and technology for study is very old. The first documented records of systematic astronomical observations occurs in Assyro-Babylonians around 1000 BCE.
While on the other hand, modern astronomy refers to the astronomy that is developed in this modern period and use advance technology. Modern astronomy includes many elements of the motions as well as characteristics of moving bodies so we can conclude that time period and technology are the main differences between ancient and modern astronomy.

8) Find the X and Y component of 10degree vector that has 5N.
Answer:
Fx = 4.92 [N]
Fy = 0.868 [N]
Explanation:
Let's take the 10 degrees as a measure from the horizontal component to the vector.
Thus taking the components in the X & y axes respectively:
Fx = 5*cos(10) = 4.92 [N]
Fy = 5*sin(10) = 0.868 [N]

Silver has a resistance of 0.0198 ohms. What voltage would produce a current of 250 amps?
Answer:
V= I x R =250 x 0.0198 = 4.95 Volts
Explanation:
The voltage across the resistor is 4.95 Volts.
How do you calculate the voltage?Given that the resistance is 0.0198 ohms and the current flowing through the silver is 250 amps.
The voltage V across the resistor is the product of the current I flowing through the resistors and resistance R.
[tex]V = IR[/tex]
Substituting the values, we get the voltage.
[tex]V = 250 \times 0.0198[/tex]
[tex]V = 4.95 \;\rm V[/tex]
Hence we can conclude that the voltage across the resistor is 4.95 Volts.
To know more about the voltage, follow the link given below.

An inclined plane is 10.0 m long and 2.5 m high. What is the mechanical advantage?
Answer:
MA = 4
Explanation:
In order to solve this problem, we must use the definition of the ideal mechanical advantage, which tells us that it is equal to the relationship of the inclined distance over the height with respect to the level of the ground
MA = L / h
where:
MA = mechanical advantage
L = Length of the inclined plane = 10 [m]
h = elevation = 2.5 [m]
MA = 10/2.5
MA = 4
