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.

A ball is released from the top of a 2-meter long ramp and rolls down with a uniform acceleration of 3 m/s^2.
a. How fast is the ball moving when it reaches the bottom of the ramp?
b. How long does it take to roll down the ramp?
Answer:
a. 3.46 m/s
b. 1.15 s
Explanation:
Given:
Δx = 2 m
v₀ = 0 m/s
a = 3 m/s²
a. Find v
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (3 m/s²) (2 m)
v = 3.46 m/s
b. Find t
Δx = v₀ t + ½ at²
2 m = (0 m/s) t + ½ (3 m/s²) t²
t = 1.15 s
Answer:

A punt is kicked at an angle of 60 with a speed of 40 m/s, and lands at the same
height from which it was kicked.
How far away will the ball land?
What is the maximum height reached by the ball?
What is the hang time? Total
Answer:
1) The ball will land approximately 141.4 m away from where it was kicked
2) The maximum height reached is approximately 61.22 m
3) The total hang time is approximately 7.07 seconds
Explanation:
First we list out the known parameters
The direction in which the punt is kicked, θ = 60°
The speed with which the punk is kicked, v₀ = 40 m/s
1) The distance away (the range, R) the ball will land is given by the equation;
[tex]R = \dfrac{v_0^2 \times sin(2\cdot \theta)}{g}[/tex]
Where;
g = The acceleration due to gravity = 9.8 m/s²
Substituting the values, gives;
[tex]R = \dfrac{40^2 \times sin(2\times60^{\circ })}{9.8} \approx 141.4 \ m[/tex]
The distance away the ball will land ≈ 141.4 m
2) The maximum height is given m=by the following equation for vertical motion;
(v₀ × sin(θ))² = 2 × g × [tex]h_{max}[/tex]
Obtained from the equation of motion, v² = u² - 2×g×h where at maximum height;
v = 0 at maximum height, the ball stops upward motion
h = Height of motion = [tex]h_{max}[/tex] at maximum height
v, and u are the vertical component of the velocity, v₀
Substituting the values in the equation for the maximum height, gives;
(40 × sin(60))² = 2 × 9.8 × [tex]h_{max}[/tex]
(40 × (√3)/2)² = 1200 = 19.6 × [tex]h_{max}[/tex]
1200 = 19.6 × [tex]h_{max}[/tex]
[tex]h_{max}[/tex] = 1200/19.6 ≈ 61.22 m
The maximum height reached ≈ 61.22 m
3) The time to maximum height is given by the following equation of motion;
[tex]v_y[/tex] = v₀ × sin(θ) - g × t
[tex]v_y[/tex] = 0 at maximum height
We therefore have;
v₀ × sin(θ) = g × t
t = v₀ × sin(θ)/g = 40 × sin(60°)/9.8 = (40 ×(√3)/2)/9.8 = 3.535 seconds
Given that the motion of the ball is symmetrical about the maximum height, we have;
The time from ground level to maximum height = The time from the maximum height back to the ground level
The total time hang time = The time from ground level to maximum height + The time from the maximum height back to the ground level
The total time hang time ≈ 3.535 + 3.535 ≈ 7.07 seconds.
The total time hang time ≈ 7.07 seconds.

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
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]
if a runner is moving 2.88m/s directly north and accelerating at .350 m/s^2 at an angle of -52.0. At the point in the motion where she is running directly east what is the displacement
Answer:
19.1 m, 52.0°
Explanation:
Given:
v₀ₓ = 0 m/s
v₀ᵧ = 2.88 m/s
vᵧ = 0 m/s
aₓ = 0.350 m/s² cos(-52.0°) ≈ 0.215 m/s²
aᵧ = 0.350 m/s² sin(-52.0°) ≈ -0.276 m/s²
Find: Δx and Δy
First, find time.
vᵧ = aᵧt + v₀ᵧ
0 m/s = (-0.276 m/s²) t + 2.88 m/s
t = 10.4 s
Now find the displacement components Δx and Δy.
Δx = v₀ₓ t + ½ aₓ t²
Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²
Δx = 11.7 m
Δy = v₀ᵧ t + ½ aᵧ t²
Δy = (2.88 m/s) (10.4 s) + ½ (-0.276 m/s²) (10.4 s)²
Δy = 15.0 m
The magnitude of the displacement is:
d² = Δx² + Δy²
d² = (11.7 m)² + (15.0 m)²
d = 19.1 m
The direction of the displacement is:
θ = atan(Δy / Δx)
θ = atan(15.0 m / 11.7 m)
θ = 52.0°

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.
