The force F is applied 45 degrees counter clockwise from the surface of the slope. The slope is 20 degrees counter clockwise from the horizontal. The magnitude of F is 60lbs. Determine the magnitude of the Force F applies along the slope

The upper leg muscle (quadriceps) exerts a force of FQ = 1180 N, which is carried by a tendon over the kneecap (the patella) at the angles shown in the figure below. 55° 75° Find the magnitude in newtons and direction in degrees counter-clockwise from an axis directed to the left of the force exerted by the kneecap on the upper leg bone (the femur). magnitude direction N ° counter-clockwise from an axis directed to the left

You are trying to overhear a most interesting conversation, but from your distance of 10.0 m , it sounds like only an average whisper of 20.0 dB . So you decide to move closer to give the conversation a sound level of 60.0 dB instead. How close should you come?  Formula: I = I0⋅10(β/10)   a) What intensity I1 corresponds to 20.0 dB ? b) What intensity I2 corresponds to 60.0 dB ?
