Aman holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.480 m/s. the total mass of the sled, man, and rock is 96.0 kg. the mass of the rock is 0.310 kg and the man can throw it with a speed of 14.5 m/s. both speeds are relative to the ground. determine the speed of the sled if the man throws the rock forward (i. e. in the direction the sled is moving).
also determine the speed of the sled if he throws the rock directly backwards.

The number of passengers who arrive at the platform of a subway station for the 10 am train is a random variable with a mean of 120 and a variance of 16. find the lower bound of the probability that there will be between 100 and 140 passengers (round off to second decimal place).

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
