Why my GPS is not working properly? Location issues are often caused by a weak GPS signal. If you can’t see the sky, you’ll have a weak GPS signal and your position on the map might not be correct. Navigate to Settings > Location > and make sure Location is ON. Navigate to Settings > […]

What is a Type 3 curve? The Type III curve, characteristic of small mammals, fishes, and invertebrates, is the opposite: it describes organisms with a high death rate (or low survivorship rate) immediately following birth. In contrast, the Type II curve considers birds, mice, and other organisms characterized by a relatively constant… What animals have […]

When you carry a heavy pail of water in your right arm Why do you tend to hold your left arm out horizontally away from your body? When you carry a heavy load—such as a pail of water—with one arm, why do you tend to hold your free arm out horizontally? Answer: You tend to […]

How do you solve chain rule problems? Solution: To use the chain rule for this problem, we need to use the fact that the derivative of ln(z) is 1/z. Then, by the chain rule, the derivative of g is g′(x)=ddxln(x2+1)=1×2+1(2x)=2xx2+1. Where do we apply chain rule? The chain rule can be applied to composites of […]

How do you find the uncertainty of a de Broglie wavelength? Heisenberg’s Uncertainty Principle. Equation 11.6. 4 can be derived by assuming the particle of interest is behaving as a particle, and not as a wave. Simply let Δp=mv, and Δx=h/(mv) (from De Broglie’s expression for the wavelength of a particle). What would be the […]

Is the stuff inside glow sticks toxic? The ingredients in glow sticks are generally non-toxic, and most cases will not require medical attention. However, if glow stick fluid is swallowed, it may cause an upset stomach and some mouth irritation. Can Glow sticks make you blind? If glow stick liquid is squirted into the eyes, […]

Is MA a force? A: Newton’s second law is defined as F=ma, where F equals force, m equals mass, and a equals acceleration. So the force exerted on an object is equal to the mass of the object multiplied by the object’s acceleration. Does an object always move in the same direction as the net […]

What is the importance of amendments? It is based on the verb to amend, which means to change for better. Amendments can add, remove, or update parts of these agreements. They are often used when it is better to change the document than to write a new one. What is the purpose of amendments? The […]

How do you calculate energy requirement? To calculate the energy required to raise the temperature of any given substance, here’s what you require: The mass of the material, m. The temperature change that occurs, ΔT. The specific heat capacity of the material, c (which you can look up). Here is a source of values of […]

What type of electromagnetic waves have the most energy? Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum. Which of these electromagnetic waves carries the most energy per photon? Gamma rays Which color frequency of light travels the fastest in a vacuum? red Can radio frequency harm you? RF radiation has […]
