Q1. A piece of wood is 6.00 m long, 0.260 m wide and 0.060 m thick. Its density is 600kg/m cubed. What volume of iron ( P iron = 7.8 x 10 cubed kg/m cubed) must be fastened underneath the wood to sink it so that the top surface of the wood is just even with the water (P water = 1.00 x 10 cubed kg/m cubed) level?
Q2. A 1.70 MHz sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward the sound receiver as the heart beats. The reflected sound is then mixed with the transmitted sound, and 85 beats per second are detected. The speed of sound in body tissue is 1500 m/s.
Calculate the speed of the fetal heart wall at the instant this measurement is made.
A generator uses a coil that has 210 turns and a 0.20-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), conclude the length of wire f..
The radar system at an airport broadcasts 15 GHz with 150 kW. An approaching airplane with a 34 m^2 cross section is 24km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all di..
A person with a mass of 103 kg is standing on a scale that reads weight in newtons inside of an elevator. If the elevator accelerates upward at 3.2 m/s2, what does the scale read.
Calculate the coil's self-inductance. If the current decreases uniformly from 5.00 to 2.00 in 3.00, estimate the self-induced emf in the coil.
At what distance from a backstop will a package need to be placed depending on its weight and knowing it has to hit the backdrop at a velocity of 66 in/sec on a 11 degree angle. What is distance for every 5 lbs of package weight.
When it rains water vapour in the air condenses into liquid water and energy is released. How much energy is released when 0.0244m of rain falls over an area of 2.59 x 10^6 m^2? If the average energy needed to heat one home for a year is 1.40 x 10^11..
Find out the velocity of the rain
You (height of your eyes above the water, 1.75) are standing 2.00 from the edge of a 2.50--deep swimming pool. You notice that you can barely see your cell phone, that went missing a few minutes before, on the bottom of the pool.
If she is served 200 of coffee at 84 in a well-insulated container, how much ice at 0 should she add to obtain a final temperature of 31.
Illustrate the force vectors with their tails at the origin of coordinate system. The orientation of your vectors will be graded. The exact lengths of your vectors will not be graded but relative length of one to the other will be graded.
Find out line linking the two point charges
At what angle is the curve banked? The acceleration due to gravity is 9.8 m/s2.
