Ron standing 1m far from a sensor moves away from the sensor for ron then halts for 2 seconds, and notes down these values. ron then walks to where the sensor was kept at a speed of 3m/s for the next 2 seconds a) draw a position time graph for this. [x - axis -time (s) y-axis position (m)] b) find out the distance from the sensor at time t 4 seconds. c) calculate the slope at t-6 seconds d) what you infer from the value obtained in (c)?

Aknife blade is a(n) a. lever b. screw c. wedge d. inclined plane

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
