River Boat Vectors and Projectiles
Suppose the motion of the river boats below. Within that case, the boat is heading across the river. Inside the top case, the presence of a current causes the boat to travel downstream as it at the same time moves across the river; the result is in which it reaches the opposite shore at a point downstream from whereas it begins. In the bottom case, the absence of a current means in which the boat moves straight across the river; it ultimately reaches a point on the opposite shore directly across from whereas it begins. It is significant to note that the current is what carries the boat down the stream; it is not the motor of the boat in which gives its downstream motion.
A bird flies in the east direction with a speed of 5 ms -1 . The wind is blowing towards north at a speed of 3 ms -1 . Determine the relative velocity of the bird with
INSTANTANEOUS VELOCITY: The velocity of a body at a certain instant of time is known as instantaneous velocity.
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
why effective mass are tensor quantities
Resolution of Forces by Calculation: One vector was resolved into two mutually perpendicular components. So if there are several vectors each can be resolved into two
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
In a Wheatstone bridge PQRS, a galvanometer is connected among Q and S and a voltage source between P and R. An unknown resistor Rx is connected among P and Q. When the bri
The discovery of neutron becomes very late because: (1)Neutrons are present in nucleus (2)Neutrons are highly unstable particles (3)Neutrons are chargeless (4)Neutrons
The maximum and minimum magnitude of the resultant of two forces are 16 N and 4N.Measure t he magnitude of individual force. Let the two vector be a and b then maxim resultant
