Resultant vector= 24 m west.
Explanation:
resultant vector= r1+ r2 when the two vectors are in same direction
r1=10m west
r2= 14 m west
so resultant displacement= 10 + 14
resultant displacement= 24 m west
So to find the mass we must use the formula D=M/V but because we don’t have the mass, we must use the formula M=DxV
So to find volume, just multiple the length (0.4m) width (0.4m) and height (2m) and you will get 0.32m as the volume. Now multiple this volume with your given density of 2,400 kg/m and you will get 768 kg as the mass of the marble block.
Final answer: 768 kilograms (kg) as mass of the marble block.
Answer;
-Sensors
-Sensors are placed on dangerous machinery to detect motion, light, heat, pressure, or another stimulus. Their presence helps protect operators from injury while working on machines.
Explanation;
-Machinery, safety and factory floor sensors and switches help workers become more productive, efficient, and safe.
-Hazardous machines and systems are frequently equipped with safety elements (safety doors) with a locking mechanism to protect the operator. Their function is to prevent hazardous machine functions if the safety door is not closed and locked and to keep the safety door closed and locked until the risk of injury has passed.
