On day three of our AmaWaterways Mekong River cruise, we wake up to find our ship docked in Phnom Penh, where we will spend the next two nights. During our time in Vietnam, we anchored mid-river and tendered ashore; we are excited that for the next two nights we are docked right in...
To find when the particle is at rest, you must set thev elocity function equal to 0 and solve for t. The velocity function is the first derivative of the position function. Remember to use the product rule on the position function in order to take the derivative correctly.x(t)=te^(...
A sports car moves along a horizontal straight road. At time / seconds the acceleration,in m s-2, is modelled using the differential equation(dv)/(dt)-2vt=t where v is the velocity of the car in m s-1.When / = 0, the car is travelling at 1 m s-1.Show that the velocity of...
“It sounds great that kids can make money for doing the latest dance moves in a 15-second video, but we should feed the minds of kids and not just their bank accounts. TikTok can be great if used properly. Money alone is not good, technology alone is not good and connectedness can ...
Light is a crucial phenomenon that enables us to perceive our environment and is essential in numerous processes like photosynthesis. A key characteristic of light is its ability to travel along a straight line, governed by its wave properties. This rect
