The waves on a string have wave speed 8.00m/s, amplitude 0.0600m, and wavelength 0.400m. The waves travel in the -x direction and at t = 0s, the end of the string has its maximum upward displacement.
(a) Write a wave function describing the wave and
(b). Find the transverse displacement of a particle at x = 0.350m at time t = 0.150s

Two resistances, one 12 Ω and the other 18 Ω, are connected in parallel. What is the equivalent resistance of the parallel combination?
In a singkil dance, two men are carrying a
princess on a bamboo pole that is 5.0 m long and weighs 200N. If the princess weighs 450N and sits 1.5 m on0 right end, how much each man support?
A sikorsky freight helicopter can easily lift a 5000 kg truck. If the acceleration of the truck is 1.5 m/s2 up, what is the net force being applied by the helicopter?
A car changes its velocity from 20 m/s [N] to 20 m/s[S] in 5.5 s. If the mass of the car is 1500 kg,
what is the net force acting on it?
A 30ft ladder weighing 100 lb having its center of the mass one-third of the way up from the bottom rests against a smooth wall so that it makes an angle of with the ground. If the coefficient of friction between the ground and the ladder is 0.4, how high can a 150-lb man go before the ladder slips?
The electric filed due in a static electric charge is 3 000 N/C and passes through a surface area of 0.3 m2. Calculate the electric flux
An object is placed at a distance of 4.5 cm to the left of a convex lens A of focal
length 4 cm.
(a) Find the distance from lens A where a screen should be placed to obtain the image.
(b) The screen is removed and the image is used as an object for a diverging lens B of
focal length 2 cm so that a real image is formed at a distance of 8 cm from lens B.
Find the distance between lens A and lens B.
A conducting and closed container of volume 300 litres contain an ideal gas at a high pressure Pinitial . Now using a pump , the gas it taken out at a constant rate 5 litre per sec . find the time in which the pressure inside the container decreases to Pinitial/100 .
