What is the major drawback to using Word equations?
What is the major drawback to using Word equations? Word equations can be very useful, but do have one major drawback. They cannot be used for any quantitative work. A word equation does not tell how many moles of each material are needed or how many moles of product are formed. What type of chemical […]
What are the three possible outcomes for the universe?
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 […]
What are three examples of interference?
What are three examples of interference? Examples of interference Part of the light from the sun bounces off the top surface, in other words it bounces off the oil. Part of the sunlight bounces off the top of the water. The light waves from the oil surface and the light from the water surface meet […]

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 = […]

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 are the negative effects of gamma rays?
What are the negative effects of gamma rays? The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. How can we reduce exposure to gamma rays? […]
Do birds feel earthquake while flying?
Do birds feel earthquake while flying? Birds and animals “feel” things in more dimensions than humans do. Birds for example are very sensitive to magnetic fields. Earthquakes being tectonic activity, I can’t see how it won’t have small impact on the earth’s magnetic field in the region. This could in turn be felt by the […]
