The astronaut's weight on the Earth's surface can be determined from
<span>F = m g = 579.2 N subsituting </span><span> mass equal to 59.1 kg and acceleration due to gravity equal to 9.8 m/s². When the variables are mass of the earth and the radius of the earth, </span>F = k m / r². Thus, doubling the mass of the earth would double his weight and doubling the radius would decrease the original weight by 1/4. Hence, <span>579.2 N* 2* 1/4 equal to 290 N. Answer is B.</span>
It is a synthesis reaction where two reactants gives one product.
