And his sonce stave a combined 15 The
para solar panel on the locational Space Station. When the cher connecting the stream
to becomes attached the astronaut holding the toolkit sarts to flat way
2) Calculato r om the space station the astronaut will be after Show your calculations and
includes in your answer
b) Calculate the momentum of the astronaut holding the tool kit as the astronaut floats way. Show your
calculations and include units in your answer
The astronaut decides the only way to change his motion and move back toward the space station is to throw
the tool
c) Identify the direction the astronaut must throw the tool kit toward the space station or away from it Use
the law of conservation of momentum to explain how throwing the tool kit may return the astronaut to the
Space Station
d) Calculate the velocity with which the astronaut must throw the tool kit in order to float back toward the
Space Station at 0.1 ms. Show your calculations and include units in your answer

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
