Answer:

The primary method by which the planets have been found around other stars in the galaxy is Kepler Space Telescope.

Explanation:

The primary method by which planets have been found around other stars in our beautiful Galaxy is the Kepler space telescope. Kepler launched Kepler Telescope in 2009 to help to find terrestrial planets super-earth etc.

This is the telescope which measures the amount of light coming from a star and detects a slight variation in brightness as a planet passes in front. Using this technique NASA's Kepler Mission has founded thousands of candidate planet in this world.

You, a 70 kg person, leap from a 10 m tall building and land feet first on a trampoline. The center of the trampoline where you

Anon25 [30]

Answer:

1373.4 N/m

Explanation:

Hooke's law states that the extension of a spring and force are related by the expression, F=kx where k is spring constant, x is extension of spring and F is the applied force. Making k the subject of the formula then

$k=\frac {F}{x}$

Also, F=gm hence the above formula is modified as

$k=\frac {gm}{x}$

Taking g as 9.81 m/s2 , x as 0.5 m and m as 70 kg then

$k=\frac {9.81\times 70 kg}{0.5m}=1373.4 N/m$

Umnica [9.8K]

Answer:

A) Cold object will start getting hot

B) Heat exchange will stop as the two object acquire the same temperature.

Explanation:

A) When one hot object and one cold object are kept in contact then the heat is transferred from the hot object to the cold object via different modes of heat transmission. Hence, the cold object starts getting hot

B) The transmission of heat from the hot object to the cold object will stop as the temperature of the two object becomes equal to each other.
