What is the size in square millimeter (mm2 ) is the cable 250 MCM size?
Calculate the power developed to lift a 8 kg mass to a height 2.4 meters in 6 seconds.
A student is only able to read the lecture notebook when it is held at 65.00cm from his eyes. What focal length and power must the lenses of his reading glasses have to bring his near point to the normal value
Two rugby players run towards each other and have an inelastic collision. Given the mass 70 kg and 60 kg respectively, and velocity 3 ms-1 and 4 ms-1. Calculate the final velocity and its direction of the respective players. Discuss how a rugby player’s bone develops if continuously performing the weight bearing exercise using Wolff’s Law and bone remodeling theory.
Dhabitah, a 60 kg diver is positioned so that her radius of gyration is 0.5 m as she leaves the board with an angular velocity of 4 rads-1. Compute Dhabitah’s angular velocity when she assumes a tuck position, altering her radius of gyration to 0.25 m. Explain how the diver applied the conservation of angular momentum to perform a somersault.
A light ray travelling from glass to air undergoes refraction. Calculate the angle of refraction to the nearest whole number if the incidence angle is 30° and the refractive for air and glass are 1.0 and 1.5 respectively.
A compound microscope consists of objective and eye piece lens of focal length 0.50cm and 1.00cm respectively. An object is placed 0.55cm from the objective lens and the final image is formed at infinity. Calculate the magnifying power of the glass and the tube L.
Four charges, q_{1} = 5.00 * 10 ^ - 7 * C q_{2} = - 3.00 * 10 ^ - 7 * C , q_{3} = - 2.00 * 10 ^ - 7 * C and q 4 =6.00* 10 ^ - 7 * t , are situated at the corners of a square if side 4.00 m. Find the potential at the center of the square.
Given: q_{1} = 5.00 * 10 ^ - 7 * c
q_{2} = - 3.00 * 10 ^ - 7 * C
q_{3} = - 2.00 * 10 ^ - 7 * C
q_{4} = 6.00 * 10 ^ - 7 * C
