the mars exploration rover (MERA) landed Mars in 2004 to explore and take pictures and samples of the rocks and soil. if MERA has a mass of 185 kg and the acceleration due to gravity on Mars is 3.7 m/s2, what is the weight of MERA on Earth and Mars?

Are a.larger

Letter a, because when there are unlike charges they will always attract to each other.

Initial velocity,  u = 4.9 m/sfinal velocity = v m/sinitial height,  h₁ =  245 m    final height, h₂ = 0a = -9.8  m/s²time taken = t secondss = ut + 0.5at²⇒  (h₂-h₁) = ut + 0.5at²⇒  0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get   t = 7.59sv  = u +  at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is  69.48 m/s downward

Because they're in different places for this the temperature varies.
