PLEASE HELP ASP GIVE POINT AND BRIALIEST The horizontal surface on which the block of mass 3.1 kg slides is frictionless. The force of 65 N acts on the block in a horizontal direction and the force of 195 N acts on the block at an 60◦ angle as shown below.
What is the magnitude of the resulting acceleration of the block? The acceleration of
gravity is 9.8 m/s^2

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

Why are graphs useful when interpreting data

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
