Well, yeah, sometimes we have that weird feeling that our guts know the answer but we don't know why. Let me show you how I got mine.
Gravitational force obeys an inverse square law - as in the gravitational force depends on the distance as<span>F = <span><span>GMm/</span><span>r</span></span></span>²
Small m is the mass of astronaut, M the planet, etc. equate the two forces to have the astronaut in equilibrium. G, m cancel, then arrange to get the Mass ratio:<span><span><span><span>Mx / </span><span>My</span></span> =<span><span>140</span></span></span></span>²/581²
Answer:
-16 g
Step-by-step explanation:
5(-8g) + 4(6g)
-40 g + 24 g they are like terms so they can be added together.
-16 g
Answer:
132 square units
Step-by-step explanation:
We are to find the surface area of a square pyramid.
From the diagram above, we are given:
Slant height = 6 units
Base = 8 units
The formula is given as:
= 2bs + b²
= 2 × 8 × 6 + 6²
= 96 + 36
= 132 square units
