The elastic energy stored in your tendons can contribute up to 35 % of your energy needs when running. Sports scientists have st
FinnZ [79.3K]

Answer:

Explanation:

From the given information:

The difference in the maximum energy stored is can be determined by finding the difference in the maximum stored energy in the sprinters and that of the non-athlete:

\Delta U = \dfrac{1}{2}k(x_2^2 - x_1^2)

\Delta U = \dfrac{1}{2} (32 \ N/mm) (\dfrac{1 \ mm}{10^{-3} \ m})  ((40\times 10^{-3})^2 - (32\times 10^{-3})^2)

\Delta U =16000 \times  (5.76\times 10^{-4})

\mathbf{\Delta U =9.216\ J}

What is the speed over the ground of an airplane flying at 100 km/h relative to the air caught in a 100-km/h right-angle crosswi
Rudiy27

Answer:

141.42 km/h

Explanation:

Since this is a 100km/h right angle crosswind, the speed vector with respect to the ground is the vector speed of the airplane with respect to air + the vector speed of the cross-wind with respect to the ground

<100,0> + <0,100> = <100,100>

This vector has a magnitude of

v = \sqrt{v_1^2 + v_2^2} = \sqrt{100^2 + 100^2} = \sqrt{10000 + 10000} = \sqrt{20000} = 141.42  km/h

How can cooler object can have more thermal energy than a warmer object?
Vladimir [108]
Temperature is only a measure of the average heat. It doesn't measure the quantity of heat. Even if a small cup of tea is really hot, it's so small. An iceberg is huge, and although cooler, will have much more heat, even if it's temperature is low

If a new ninth planet were discovered in our solar system that orbited the Sun in an opposite direction than the other eight pla
faltersainse [42]

For this ninth planet, astronomers would most likely assume that: it originated in another star system and was gravitationally captured.

<h3>What is a solar system?</h3>

A solar system is a collection of both outer and inner planetary (astronomical) bodies alongside the Moon that usually orbit around the Sun, in slightly elliptical orbits.  

<h3>The planets in the solar system.</h3>

Based on astronomical science, there are nine (9) planets in the solar system and these are;

  • Mercury
  • Venus
  • Earth
  • Mars
  • Jupiter
  • Uranus
  • Neptune
  • Pluto
  • Saturn

Astronomers would most likely assume that a planet that orbited the Sun in an <u>opposite direction</u> in contrast to the other planets, originated in another star system and was gravitationally captured.
