Block A has a mass of 6kg and block B has a mass of 3kg. Block B is falling, as block B is falling it accelerates to the right at 1.32m/s^2, the coefficient of kinetic friction between block A and the surface is is 0.3. Assume the connecting rope has negligible mass. The pulley's mass is only to redirect the chord. a.) Find force exerted by the surface on block A

b.) Find the frictional force

c.) Find the tension in the chord

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.

At what time would the magnitude of the velocity reach 36.00 km/hr
