Position from polar velocity A particle P starts at time t 0s at the position r 3 m y-4 m. The velocity v of the particle is written in the polar basis associated with its current position, and is: In the above expression, t is in seconds. Matlab/Mathematica input: y0-4 What is the position of P att-4 s?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
