How strong can isometrics make you? Even the earliest studies of isometrics showed enormous strength gains, up to 5 percent per week. [5] Imagine doubling your strength in 20 weeks! It can be done and has been done using isometrics. You might be thinking, “Yeah, but isometric strength is only good when you’re not moving. […]

Is drag force equal to weight? The drag force depends on the square of the velocity. So as the body accelerates its velocity and the drag increase. It quickly reaches a point where the drag is exactly equal to the weight. When drag is equal to weight, there is no net external force on the […]

Does water reflect or absorb sound? As sound travels through a medium such as water, it gets absorbed – caught by the molecules within the medium. They do this by stealing some of the energy from the sound wave. The absorption in sea water is much greater than would be expected due to the viscosity […]

How long until trazodone kicks in for sleep? It can take 1 to 2 weeks before trazodone starts to work, but may be 4 to 6 weeks before you feel the full benefit. Trazodone can make you feel sleepy. If you take it once a day, it’s best to take it in the evening or […]

What are the components of tRNA? The two most important parts of a tRNA are its anticodon and the terminal 3′ hydroxyl group, which can form an ester linkage with an amino acid. However, there are other aspects to a tRNA’s structure such as the D-arm and T-arm, which contribute to its high level of […]

Which of the following is needed to warm up 1g of any substance by 1 0c? Specific heat means the heat to raise the temperature of 1 gram of the material by 1 degree C. So if you want to raise the temperature of that one gram from 19 to 35 degrees, that same gram […]

Is gravitational force dependent on mass? Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. What are the factors affecting gravity? […]

What are the two types of muscular endurance? The two main types are fast-twitch and slow-twitch, according to ACE Fitness. Slow-twitch fibers play the greatest role in muscular endurance. They do not generate much force, but they are far more resistant to fatigue than fast-twitch muscles. What two types of muscular endurance are there? Types […]

What is conservation of momentum derive the formula? ⇒m1​v1​+m2​v2​=m1​u1​+m2​u2​ ⇒ Final momentum (pf​) = Initial momentum (pi​). Thus, we conclude that during the interaction between the two balls, momentum before collision is equal to total momentum after collision. Thus, the momentum of the system is conserved in the absence of external forces. Why is the […]

What type of diffusion is hair? The 3 Types/Terms of Expansion Diffusion ​Example: Many people cutting their hair the way Taylor Swift did. Example: Different Menu items from McDonalds around the world. What type of diffusion is religion? Religion uses nearly all forms of diffusion to reproduce itself across space. Hierarchical diffusion generally involves the […]
