Drill 3.0 m
5.0 kg
BONUS QUESTION: A drill vibrates at 20 Hz. The drill is attached to a rope, producing
standing waves as shown above. If the 5.0 kg mass was replaced with an object MUCH
heavier increasing the tension in the string, the wavelength would
A. Increase
B. Decrease
C. Stay the same
D. Unable to be determined
Justification:
*be sure to explain your answer please* ;)

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.

Check the following equation for dimensional homogeneity: ⅆ mv=∫t1t2(f⁢cosθ)ⅆt where m is mass, v is velocity, f is force, θ is an angle, and t is time. check that each term in the equation has the following dimensions: [malbec] where you are to choose the coefficients a, b, c.
