How likely is it that the Earth will be hit by an asteroid? Currently none are predicted (the single highest probability impact currently listed is ~7 m asteroid 2010 RF12, which is due to pass earth in September 2095 with only a 5% predicted chance of impacting). Currently prediction is mainly based on cataloging asteroids […]
Which object has the most potential energy?
Which object has the most potential energy? The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Is heat an example of potential energy? Heat is not an example of potential […]
What does too much oxygen do to fish?
What does too much oxygen do to fish? Too much oxygen in water can lead to the potentially lethal gas bubble disease, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes. (Excess nitrogen, however, is a far more common cause of this disease.) How do […]

Is freeze/thaw an example of physical weathering?
Is freeze/thaw an example of physical weathering? There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion. Is freeze and […]
How dangerous is static?
How dangerous is static? Static electricity can build up in clouds. It is dangerous when you touch something with a large electric charge on it. The charge will flow through your body causing an electric shock. This could cause burns or even stop your heart. How can we control static electricity while loading and unloading […]

Which are the important therapeutic radiopharmaceuticals in nuclear medicine?
Which are the important therapeutic radiopharmaceuticals in nuclear medicine? hi practice, radionuclides that emit beta par- ticles, as well as those capturing electrons and emitting what are known as Auger electrons, are the only ones that have been used in therapeutic nuclear medicine. Why half life is so important for a radionuclide used in nuclear […]
Why do microscopes use plane mirrors?
Why do microscopes use plane mirrors? Plane or concave mirror, placed on the microscope base and used to send light onto the specimen and into the microscope optics. The mirror is mounted on a swiveling support, adjusted to reflect natural light or light from an artificial source in the desired direction. Is used in Periscope? […]
