Is it safe to do strength training everyday? You need to be hitting the weights at least three days per week. The research says that at the very least, training a minimum of two days per week is needed to maximize muscle growth. What is the most dangerous exercise? 5 Dangerous Lifts Overhead squat. While […]
Is a motorcycle a mechanical energy?
Is a motorcycle a mechanical energy? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that you […]
What happens when an electron jumps to a higher energy level?
What happens when an electron jumps to a higher energy level? What happens when electrons jump between energy levels? Answer: As electron move away from the nucleus, it gains energy and becomes less stable. When electron jumps from lower energy level to higher energy level, it gains energy from surroundings which is known as absorption […]
Why electric field is created?
Why electric field is created? Electric fields originate from electric charges, or from time-varying magnetic fields. The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point. What […]
What is the relationship between speed and torque?
What is the relationship between speed and torque? Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Why […]
What is the shortest distance between two lines?
What is the shortest distance between two lines? Distance between two Straight Lines In geometry, we often deal with different sets of lines such as parallel lines, intersecting lines or skew lines. The distance is the perpendicular distance from any point on one line to the other line. The shortest distance between such lines is […]
How long does it take to depressurize an airlock?
What are four ways that waves interact with matter?
What are four ways that waves interact with matter? Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. The types of interactions are reflection, refraction, and diffraction. Each type of interaction is described in detail below. What is the measure of energy in a wave? Amplitude […]
What technology is on the moon?
What technology is on the moon? Other technologies like breathing apparatuses, fabric structures, communications and protective coatings that made man’s step on the Moon possible soon led to giant leaps in technology on Earth. What technology has NASA given us? Health and medicine Infrared ear thermometers. Ventricular assist device. LASIK. Cochlear implants. Artificial limbs. Light-emitting […]
Is nuclear power bad for the environment?
Is nuclear power bad for the environment? “Nuclear energy has perhaps the lowest impact on the environment — including air, land, water, and wildlife — of any energy source. It produces no harmful greenhouse gases, isolates its waste from the environment, and requires less area to produce the same amount of electricity as other sources. […]
