Is Earth losing its magnetic field? Reversals occur nearly randomly in time, with intervals between reversals ranging from less than 0.1 million years to as much as 50 million years. The most recent geomagnetic reversal, called the Brunhes–Matuyama reversal, occurred about 780,000 years ago. Where is Earth’s magnetic field strongest? magnetic north pole Can humans […]
How strong is tuff rock?
How strong is tuff rock? Tuff rock has geotechnical properties such as 18-25 kN/m3 of unit weight, 1.5 – 2.4 gr/cm3 of bulk density, 2.29 – 2.64 gr/cm3 of particle density, highly varied compressive strength depending on the degree of weathering, 0 – 1.45 MPa of cohesion, friction angle = 24° – 45° of friction […]
How long does aspirin take to dissolve in water?
How long does aspirin take to dissolve in water? After the Alka-Seltzer tablet was added to the hot water the tablet should have quickly dissolved, taking some 20 to 30 seconds to do so, depending on the exact temperature. Does aspirin dissolve water? Solubility. Aspirin is only slightly soluble in water and acidic solutions such […]
How can you strengthen a magnetic field?
How can you strengthen a magnetic field? You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil. Can you reverse magnetic polarity? The polarity of a magnet actually can […]

Which type of mirror can form a real image?
Which type of mirror can form a real image? Solution: Concave mirrors can form real images. Convex and plane mirrors always form virtual images. Want to top your science exam ? How important is plane mirror to you? Plane mirror reflections create upright virtual images at the same magnification, or size, and distance as the […]
What is Mew M?
What is Mew M? The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equalling 1×10−6 metre (SI standard prefix “micro-” = 10−6); that is, one millionth of a metre (or […]
Do volcanoes cause lightning?
Do volcanoes cause lightning? Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice), which generate static electricity within the volcanic plume, leading to the name dirty thunderstorm. Moist convection and ice formation also drive the eruption plume dynamics and can trigger volcanic lightning. What does volcanic earthquake mean? A volcano tectonic […]
What are the embryological evidence that we all have a common ancestry?
What are the embryological evidence that we all have a common ancestry? They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos. What is the evidence of embryology? The study of one type of evidence of evolution […]
