How does a rigid rotor work? Rigid rotor is a type of rotor system used on helicopters. The helicopter blades are fixed to the rotor hub without hinges and the hub is fixed to the rotor shaft. The blades of rigid rotor systems are able to flex, which allows the blades freedom to feather but […]

What three things can light rays travel through? The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; and (3) after being reflected from a mirror. […]

What is considered Hypokinetic disease? The term “hypokinetic diseases” describes many of the diseases and conditions associated with inactivity and poor fitness and include: obesity, metabolic syndrome, high blood pressure, high cholesterol, osteoporosis, osteoarthritis, low back pain, type 2 diabetes, some cancers, depression and other bio-behavioral … What is the sitting disease? Including exercise and […]

What does buoyancy depend on? The buoyant force depends on the mass of the object. The buoyant force depends on the weight of the object. The buoyant force is independent of the density of the liquid. The buoyant force depends on the volume of the liquid displaced. Does buoyancy depend on material? The buoyant force […]

Can a human see ultraviolet light? cMost humans cannot see ultraviolet light because it has a shorter wavelength than violet light, putting it outside of the visible spectrum. How many FPS can a 144Hz monitor display? 144FPS What FPS is good for gaming? 30 FPS – Good enough for a single-player. It sometimes makes for […]

What are the five principles of sustainable development? The principles of sustainable development are as follows: Conservation of ecosystem. Development of sustainable society. Conservation of biodiversity. Control of population growth. Development of human resources. Promotion of public participation. What are the 3 principles of sustainability? Therefore, sustainability is made up of three pillars: the economy, […]

What is recoil speed? In a typical recoil situation, the release of a body of smaller mass (body 1) has an impact on a larger body (body 2). If both bodies start from rest, the law of conservation of momentum states that m1v1 = -m2v2. The recoil velocity is typically the velocity of body 2 […]

Is CPU a part of microprocessor? Many admins use CPU and microprocessor interchangeably, but the reality is that while a CPU is essentially a microprocessor, not all microprocessors are CPUs. Is a CPU a microcontroller? A microcontroller (MCU for microcontroller unit) is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. A […]

Can you gain muscle at home? Yes, bodyweight exercises can build muscle if you use the following principles: increase reps, decrease rest times, perform variations, train to failure, increase time under tension, and implement mechanical drop sets. What’s the best home workout program? Here’s the deal with 13 of the most popular home workout programs […]

What is the efficient of machine? The efficiency of a machine is equal to the ratio of its output (resistance multiplied by the distance it is moved) to its input (effort multiplied by the distance through which it is exerted); it is also equal to the ratio of the AMA to the IMA. What is […]
