Neutrinos are hard to detect because they are 100,000s of times smaller than an electron, so are too small to detect with current equipment. They also dont have a charge and do not interact with any other...
By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1.We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific ca...
First of all, it is important to remember that an object's acceleration is the rate of change of its velocity, not its speed. Velocity is a vector quantity and so must have a direction as well as a magnit...
Acceleration (A)= Angular Velocity2 (w2)Displacement (x)Angular Displacement= 2piFrequency (f)Gradient= A/x = w2 = [2pi*f]2Rearrange the equation to g...
An oscillation is send down the string which is reflected at the other end. This leads to the superposition of two waves, the transmitted and reflected wave, on the string. At the ends, where reflection o...
