First you must make a free body diagram of each body to find the acceleration of each one. After you find the general formula of acceleration, you must replace the values of K for each body. (Assuming they all have the same mass). Finally, by replacing K, the body that gets the most acceleration will be the first to reach the bottom.I attached the solution.In this case the solid sphere reaches the bottom first.

viewed from earth two stars form an angle of 76.04 degrees. StarA is 23.30 light years from earth star Bis 34.76 light years fro
kirill115 [55]
The observation point on Earth and the two stars form a triangle. The two sides of the triangle are 23.3 ly and 34.76 ly and their included angle is 76.04°. We can use the cos rule to find the third side, which is the distance between the two stars.
c² = a² + b² - 2abCos(C)
c² = (23.3)² + (34.76)² - 2(23.3)(34.76)Cos(76.04)
c = 36.88 light years.

A wind turbine has a total input power of 2 500 kW.
Sonbull [250]

Answer:

Output power = 500 KW

Explanation:

Given the following data;

Efficiency = 20%

Input power = 2500 KW

To find the output power;

Efficiency = \frac {Out-put \; power}{In-put \; power} * 100

Substituting into the equation, we have;

LET Output power = OP

20 = \frac {OP}{2500} * 100

Cross-multiplying, we have;

20 * 2500 = OP * 100

50000 = OP * 100

OP = \frac {50000}{100}

Output power = 500 KW

Which of the following types of stars is the coolest? In Graph A, the curve peaks at 800 nm, in the red section of the visible l
ASHA 777 [7]

im no scientist but im pretty sure cool stars are warm colors and hot stars are cool colors, so red would be more cooler than blue.

Why are there so few eclipses in 2014?
Sonbull [250]

Answer:

Because the Moon casts a smaller shadow than Earth does, eclipses of the Sun tightly constrain where you can see them. If the Moon completely hides the Sun, even for a moment, the eclipse is considered total.
