Aprojectile is fired with an initial velocity v0 = 100 m/s and a firing angle alpha = 30o. construct the proper loop to populate the arrays that store the values of x = t * v0 * cos(alpha) and y = t * v0 * sin(alpha) - (1/2) * g * t2 , where x and y are the horizontal and vertical coordinates of the projectile at any time t measured from the firing point, and t is the time in seconds.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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?

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
