If the initial velocity of a car is 14.62 meters per second and its final velocity is 45.46 meters per second, what is its acceleration in meters per second squared if it takes 2.57 sec to make this change? Round your answer to two decimal places. A car's speed is 245.2% of a ...
The particle's speed is defined as the distance traveled by the particle per unit of time. In other words, it is the ratio of the distance to the time taken to cover the distance as follows: v = st Where: s is the distance traveled by the particle in a time interval...

(c) What happens to the speed of the reaction when(i) smaller pieces of zinc are used?goes faster/more hydrogen given off per minute /more gas given off per unit time/les time for same amount of gas(ii) some water is added to the sulfuric acid?goes slower/less hydrogen given offper...
Kilobits per second (Kbps):This is a unit of measurement for data transfer speed. One kilobit is equivalent to 1,000 bits per second. Megabits per second (Mbps): These are the units of measurement for throughput and network bandwidth. They are utilized to demonstrate the speed of an interne...
Speed In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an objec...
