Explanation The relative position of three vans is shown in the figure below. Van 2 is at rest and van 1 and van 3 is moving with velocity v → in opposite directions. Write the expression of frequency when the source is fixed and observer is moving with velocity v → f = f 0 ⋅ ( 1 − β ) ( 1 + β ) (I) Here, f 0 is the actual frequency, f is the apparent frequency and β is the time dilation constant. The above equation gives the apparent frequency of van 1 with respect to van 2 and the apparent frequency of van 3 with respect to van 2. The apparent frequency of van 1 with respect to van 3 is different as both the observer and source is moving

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot mov…

Two concrete spans of a 234 m long bridge are placed end to end so that no room is allowed for expansion (Figure a). Each span therefore has a length of L0 = 117 m. If the temperature increases by 17.8 °C, what is the height y to which the spans rise when they buckle (Figure b)? (The coefficient of linear expansion of concrete is 1.20⋅10−51.20⋅10-5 °C−1.)

Monkey D. Luffy, from One Piece can inflate himself like a balloon to a size of 6.98 m3 by inhaling 1.74⋅10^26 molecules of air. If the air is at 20.9 ˚C, the pressure inside Luffy is 101277.062 Pa. kB=1.38⋅10^−23 J/K. The total internal energy of the gas inside Luffy is 1065333.93 J. How fast, on average, is the air molecules inside Luffy traveling at? The average mass of an air molecule (considering the various gasses involved) is 4.51 x 10^-26 kg.

The Dungeons & Dragons spell “Stinking Cloud” fills a 949 m^3 volume of air with a cloud of gas. The pressure of the gas is the same as the air, 101,325 Pa, and is at 29.2°C. There are 2.304x10^28 molecules of gas. What is the total internal energy of the gas?
