Fourth Harmonic-Standing Waves on a String
There are a variety of patterns that could be generates through vibrations inside a string, slinky, or rope. Every pattern corresponds to vibrations that occur at a particular frequency and is called as a harmonic. The lowest possible frequency at that a string could vibrate to form a standing wave pattern is called as the fundamental frequency or the first harmonic.
Variation of temperature of a body according to Newton's law: Let Consider a system has a temperature Φi at time t = 0. It is placed in an environment whose temperature is Φ0. We a
A conductor moves with a velocity of 20m/s at an angle of (a) 90 ? (b) 45 ? (c) 30 ? , to a magnetic field produced among two square-faced poles of side length 2.5cm. If the
The conductive method Heat can be transferred by conduction from warmer to cooler objects, the quantity of heat transfer depends on the temperature difference between the two
The Tesla and the Gauss are units of measure of: a) Conductance b) Magnetic field strength c) Magnetic flux d) Electrical current Ans: The Tesla and Gau
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 7.5 km/s and the secondary, or S, wave
What is Heat? We now have several scales for measuring temperature, but first let's ask, “Is temperature the same as heat?” If I add heat to a pot of water, the water's temperatu
At what angle should a body be projected with a given velocity 24m/s just to pass over the obstacle 14m high at a given distance of 24m. Solution: 14=24xtan(θ)-(g*)(24 2
Using a pulley Use the pulley set-up shown in experiment A 12. Apply the force on the movable pulley and get how rapidly the weight on the other end of the string rises.
