Answer:
Dynamic stretching
Explanation:
Dynamic stretching is a form of stretching beneficial in sports utilizing momentum from form.
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that the magnetic force on the current carrying wire is given as
so we have
so we have
Part b)
Now magnetic field is changed to 0.55 T
so we will have

Explanation:
The Hubble space telescope is a space telescope that was launched to lower the orbit in 1990 and remains in operation. it was not the first space telescope, but it is one of the largest and most versatile, well known as both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble, and is one of NASA’s great observatories, along with Compton GammaRay observatory, the Chandra x-ray observatory, and the Spitzer Space Telescope.
Hubble features a 2.4 meter mirror, and it’s four main instruments observed in the ultraviolet, visible, and near in-fraired regions of the electromagnetic spectrum.
Hobbles orbit outside the distortion of earths atmosphere allows it to capture extremely high resolution images with the substantially lower background light than ground base telescopes. it has recorded some of the most detailed visible light images, allowing a deep view into space. Many Hubble observations have led to the breakthroughs in astrophysics, such as determining the right of expansion of the universe.
The Hubble telescope was built by the United States space agency NASA with the contributions from that European space agency. The space telescope science Institute select hobbles targets and processes the resulting data while Goddard space flight Center controls the spacecraft. Space telescope for repost as early as 1923. Hubble was founded in 1970s with the proposed launch in 1983, but the project was reset by technical delays, budget problems, and the 1986 challenger disaster. It was finally launched by space shuttle discovery in 1990, but its main mirror had been ground incorrectly, resulting in spherical aberration that can promise to telescopes capabilities. The optics were corrected to their intent to quality by a servicing mission in 1993. How old is only telescope designed to be maintained in space by astronauts. Five space shuttle missions have repaired, upgraded, and replace systems on the telescope, including all five of the main instruments. The first mission was initially canceled on safety grounds following the Columbia disaster which was in 2003, but nice administrator Michael D Griffin approved the fifth servicing mission which was completed in 2009. The telescope was opening as of April 24, 2020 is 30th anniversary, and could last until 2030-2040. One successor to the Hubble telescope is the James Webb space telescope which is scheduled to be launched in late 2021.
