Yes, this is certainly ugly and scary.
Here's how to go about it:

-- Take the two resistors in the middle ... the  9  and the  8 .
   They're in parallel.
   Their equivalent resistance is something like 4.24 ohms.  Whatever.

-- Take the two resistors around the outside on the right ... the 4 and the 6 .
    Together, in series, they're equivalent to  10 ohms.

-- That 10 ohms is in parallel with the ~4.24 ohms in the box.
    Now you have something like  2.98 ohms, all to the right of the 3 on top.

--  That 2.98 is in series with the 3.0 on top.
     So there's  5.98 ohms.

-- The 20.0 is in parallel with the  5.98 ohms.
    So that's about 4.6 ohms equivalent between 'A' and 'B'.

That's just off the top of my head.  I won't sharpen it down
any further than that, because it's only 5 points, and you
should be able to do it now, using this approach.

Answer:

Use the formula

g = GM/R^2

where

g = acceleration of gravity on moon

G = universal gravitational constant

= 6.67 x 10^-11 m^3/kg-s^2

M = mass of the moon

R = radius of the moon

solving for R, we get

R = 1.74 x 10^6 kg

An astronaut on the moon throws a baseball upward. the astronaut is 6ft, 6 in. tall and the initial velocity of the ball is 30 f
Ainat [17]
The equation is garbled and the question is missing.

I found this equation for the same statement:

S = - 2.7t ^2 + 30t + 6.5

And one question is: after how many seconds is the ball 12 feet above the moon's surface?

Given that S is the height of the ball, you just have to replace S with 12 and solve for t.

=> 12 = - 2.7 t^2 + 30t + 6.5

=> 2.7t^2 - 30t - 6.5 + 12 = 0

=> 2.7t^2 - 30t + 5.5 = 0

Now you can use the quadratic equation fo find t:

t = { 30 +/- √ [30^2) - 4(2.7)(5.5)] } / (2*2.7)

=> t = 0.186s and t = 10.925 s

Answer: after 0.186 s the ball is at 12 feet over the surface, and again 10.925 s

blsea [12.9K]

Answer:

Explanation:

Mass of the Jupiter is 319 times more than that of the earth but its acceleration due to gravity is only 2.5 times more than the earth because the radius of the Jupiter is about 11 times greater than the earth.
