Answer:
Increase
Explanation:
The plane strain fracture toughness of a metal is expected to increase with rising temperature.
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.
<h2>
The car tire makes 149 revolutions before coming to stop.</h2>
Explanation:
a) We have equation of motion v² = u² + 2as
Initial velocity, u = 32.4 m/s
Acceleration, a = -1.70 m/s²
Final velocity, v = 0 m/s
Substituting
v² = u² + 2as
0² = 32.4² + 2 x -1.70 x s
s = 308.75 m
Distance traveled before stopping is 308.75 m
Radius of tire = 0.330 m
Circumference of tire = 2πx 0.33 = 2.07 m
1 revolution = 2.07 m
The car tire makes 149 revolutions before coming to stop.
The giant squid, which has an estimated weight of 0.37 tons dispersed across a length of 40 feet, is the biggest invertebrate. It will weigh 3,628.4605 newtons.
<h3>What is weight?</h3>
The weight of matter is found as the product of the mass and the gravitational acceleration.
Unit conversion;
1 ton = 9806.65 N
0.37 tons = 0.37 × 9806.65 N
0.37 tons = 3,628.4605 N
Hence its weight in newtons will be 3,628.4605.
