A particle is projected from an origin O at a velocity of (4i + 13j)m/s. Find the position vector of the particle 2 seconds after projection and the distance the particle is then from O(take g= 10m/s²

If steel is more dense that lake water, why can a boat float

Select the three ways that the parallel-plate capacitor differs from a car battery.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
