How do you develop scientific temper among students? Incredible Tips to Develop Scientific Temper In Children Create a pro-science home. Encourage your child to ask questions about almost everything. Develop critical thinking skills. Support their experiments. Opportunities to apply what they learn. Employ games and electronic devices. Who is responsible for the development of scientific […]

How do you find the potential and kinetic energy of a pendulum? Energy in a Pendulum GPE can be calculated by multiplying the mass, the acceleration due to gravity, and the height change. Once the mass is let go, it starts to swing. Kinetic energy (KE) is the energy of motion, and is the product […]

How many V m is dangerous? No known health effects are expected if your exposure to EMF falls below the levels in the following guidelines: natural electromagnetic fields (like those created by the sun): 200 V/m. power mains (not close to power lines): 100 V/m. power mains (close to power lines): 10,000 V/m. What is […]

What is the best way to stay safe when facing an aggressive driver? When faced with an aggressive driver, AAA recommends that you: Avoid eye contact. Refrain from hand gestures. Give the aggressor space. Remain in your vehicle. Contact emergency services if necessary. What is aggressive driving should be avoided? Such actions are dangerous to […]

What is kinetic theory of matter for Kids? The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, […]

Why did the big bang never happen? According to Lerner – who wrote the book “The Big Bang Never Happened” – no helium or lithium was created before the development of the first stars in our galaxy. In a statement, Lerner said the mismatch of evidence on the presence of lithium in the cosmos has […]

What is the formula for volume in cylindrical coordinates? In cylindrical coordinates, we have dV=rdzdrd(theta), which is the volume of an infinitesimal sector between z and z+dz, r and r+dr, and theta and theta+d(theta). As shown in the picture, the sector is nearly cube-like in shape. How do you plot Cartesian coordinates? To plot any […]

What is the purpose of coiled wires? Coiled wires (also called retractile cords) are great for keeping long wires tidy and together. Their springy nature allows them to be stretched and then return to their coiled shape, keeping your wire localized and neat looking. Can Ethernet cable be coiled? A tightly coiled 10M length of […]

Is gravitational force attractive in nature? We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any. What is gravitational force is always in nature? (c) Gravitational force is always independent of other masses in the surroundings. How […]

What are the three layers of the earth answer? The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, […]
