: Suppose the PASCO Motion Sensor is calibrated to give correct measurements of position at 20o C, but the actual temperature in the lab room is 22o C. The Motion Sensor works by timing how long a pulse of sound takes to go from the sensor to the cart and back to the sensor, and at 20o C, the speed of sound is 343.15 m/s, but at 22o C, the speed of sound is 344.31 m/s. What effect does this difference in the speed of sound make, and what kind of error is this

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0

The three phases of general adaptation syndrome are alarm, resistance, and recovery. select the best answer from the choices provided t f

Abody of mass 20 kg is kept in equilibrium of two forces. if one of the ropes pull the body in a horizontal direction and the other in a direction of 60 degree with the vertical, calculate the tension in each rope.
