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 […]
What is the ability to change matter?
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 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 […]
What is an example of speed and velocity?
Which is called the living part of a cell?
Which is called the living part of a cell? Protoplasm (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasms) is the living part of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). Is a living […]
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 […]
