Calculate the force of gravity on a spacecraft 19200 km (3 earth radii) above the Earth's surface if its mass is 1600 kg. Hint: At three earth radii from the surface of the Earth, the gravity force (weight) of the spacecraft will be reduced to (1/4)^2 = 1...

Can anyone help work these problumns out step by step? 11x-37=x+23 10p-26=p-44 -13x+5=4x-6 -7x+13=4x-7 11x+5=17 -11x+13=-42 -15y+26=-19 5x-13=9x+15 6q-14=11q-19 4(-2x-5)=29 12(2-5x)=(3x-1) 9x+2=15x-10 19q+4=7q-3 6(2x+1)=9(2x+6) -7(x-3)=8(4-5x) -3(p-4)=8(4...

The ratio of the number of male lions to female lions in the animal reserves is 21:20. If there are 123 lions in the animal reserve, how many of the lions are female? Thank you!

You are given a fraction in simplest form. The numerator is not zero. When you write the fraction as a decimal, it is a repeating decimal. Which numbers from 1 to 10 could be the denominator? THANK YOU!

Should the quotient of an integer divided by a nonzero integer always be a rationalnumber? Why or why not? THANK YOU!

8) Things that are equivalent according to the equivalence principle are ( 2 pts) (a) space and time. (b) a traveling twin and a stay-at-home twin. (c) gravity and acceleration. (d) mass and energy.

thankyou but, so what would you say the answer is a,b,c or d?

okay so the answer is b?

Bob was mostly right, however when he took into consideration of the gravity on the down side he forgot to input the static friction that goes against gravity pulling the block down the slope. Tension= (Us*(mass*9.8cos(theta))-((mass*9.8sin(20))-(Us*(mass...
