What are the three possible outcomes for the universe? The three possible outcomes include: an open universe, in which the expansion will never stop; a closed universe, in which the expansion will stop and turn into a contraction; and a flat universe, in which the expansion will slow to a halt in time—but it will […]
Why are steam machines good for the environment?
Why are steam machines good for the environment? STEAM CLEANING The deep cleaning effect of steam ensures that bacteria and other unwanted micro-organisms are destroyed, even right down into the deepest pores of the polluted surface. Subsequently the minimal residue left behind by the use of steam can be removed by the simultaneous use of […]

What is a normal breast size?
What is a normal breast size? In the last 15 years, the average bust size has increased from 34B to 36C. Whether the lift is due to breast augmentation surgeries or a side-effect of expanding waistlines is not known. Either way, from slinky to full-coverage undergarments, bras have graced the bodies of women since the […]
What is the maximum acceleration of a bungee jumper?
What is the maximum acceleration of a bungee jumper? We can see this because the upward force is at a maximum when the bungee cord is fully stretched. The jumper reached the highest position in the middle of the second free-fall period, or about 2.4 s. The acceleration is downward and about –9.8 m/s2. How […]
What liquid is used in lava lamps?
What liquid is used in lava lamps? The whirling globs we remember are made mainly of paraffin wax, with compounds like carbon tetrachloride added to increase its density. The liquid the wax floats in can be water or mineral oil, with dyes and sparkles added for whimsy. Is it real lava in lava lamps? The […]
How do you calculate retarding force?
How do you calculate retarding force? 1. Find the accelerating and retarding (stopping) force: Accelerating force: First, find acceleration: 50 km/h is equal to 13.89 m/s (we calculated this with the speed converter). Retarding force: a = (0 – 13.89 m/s) / 8 s = -1.74 m/s2 Fr = 50 kg * -1.74 m/s2 = […]
Which of the following is evidence of plate tectonics?
Which of the following is evidence of plate tectonics? Material in the mantle is constantly circulating as a result of heat within the mantle. As the partially molten rock flows, the tectonic plates move as well. Other evidence of plate tectonics include Seafloor spreading, which involves the creation of new crust at divergent plate boundaries. […]
What are the normal chromosome numbers of a sperm egg and zygote?
What are the normal chromosome numbers of a sperm egg and zygote? Healthy humans have 46 chromosomes, 23 from the sperm and 23 from the egg. An embryo with the wrong number of chromosomes is usually miscarried, or develops disorders such as Down’s syndrome, which is caused by an extra copy of chromosome 21. What […]
