Suppose we have a simple machine. All the memory addresses lower than or equal to 100 belong to the kernel space, and the memory addresses higher than 100 belong to the user space. Suppose that the mode register has value 0 when the processor is in the kernel mode; 1 when in the user mode. Given the above information, please modify the instruction decode phase to check whether the instruction has a mode violation. Please write down the pseudo-code.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

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?
