Solve the all part of given problem:

Problem: Assume the mostly infrared radiation from a heat lamp acts like a continuous wave with wavelength 1.50 µm.

Part 1: If the lamp's 220 W output is focused on a person's shoulder, over a circular area 27.0 cm in diameter, what is the intensity?

kW/m²

Part 2: What is the peak electric field strength?

kV/m

Part 3: Find the peak magnetic field strength.

µT

Part 4: How long will it take to increase the temperature of the 4.00 kg shoulder by 2.00°C, assuming no other heat transfer and given its specific heat is 0.830 kcal/kg °C?

I need expert help to solve the all parts of above given problem.
