Answer:

The minimum speed = \sqrt{\frac{2GM}{R} }

Explanation:

The minimum speed that the rocket must have for it to escape into space is called its escape velocity. If the speed is not attained, the gravitational pull of the planet would pull down the rocket back to its surface. Thus the launch would not be successful.

The minimum speed can be determined by;

                      Escape velocity = \sqrt{\frac{2GM}{R} }

where: G is the universal gravitational constant, M is the mass of the planet X, and R is its radius.

If the appropriate values of the variables are substituted into the expression, the value of the minimum speed required can be determined.

HELP <br> which two changes to a metal wire both increases resistance? the answer is B but why ?
djverab [1.8K]

Answer:

<h2>option C </h2><h2>decreasing its thickness and increasing its temperature. </h2>

Explanation:

<h2>Resistance is directly proportional to length and temperature of the wire and inversely to area.</h2>

<h3>if you increase the temperature the resistance will increase.(resistance is directly proportional to temperature)</h3>

<h3>if you decrease its thickness (area) then the resistance will increase ( resistance is inversely proportional to area)</h3>

hope it helps:)
