How visual information is processed in the brain? Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in […]
What are the two rules of refraction?
What tissue sends messages from brain to body?
What tissue sends messages from brain to body? Neuron. Neurons allow the brain and body to communicate by relaying sensory information and motor commands as electric signals. The most complex workings of the nervous system depend on messages sent through neurons. Together with their support cells, neuroglia, neurons make up all nervous system tissue. How […]
What does healthy living mean to you?
What does healthy living mean to you? ‘Healthy living’ means maintaining a healthy lifestyle and introducing habits that improve your health. It can be difficult to change old habits, but there are steps you can take to become healthier. Why good health is important? Being healthy should be part of your overall lifestyle. Living a […]
How do planetary gears increase torque?
How do planetary gears increase torque? A planetary gearhead takes a high-speed, low-torque input, say from an electric motor, then increases torque and reduces speed at the output by the gearhead ratio. This lets motors run at higher, more-efficient rpms in equipment that operates at low speeds. Why are there planetary gears? Generally, planetary gears […]
Can you use an accelerometer to measure force?
Can you use an accelerometer to measure force? Accelerometers work by detecting forces. We look at the force acting on a small mass, divide it by the object’s mass, and calculate the force per unit mass. The electronic accelerometer is well suited for recording these forces. Can an accelerometer measure force? An accelerometer is an […]
What type of relationship is there between wavelength and frequency?
What type of relationship is there between wavelength and frequency? Frequency and wavelength have both direct and inverse relationships. For instance, if two waves are traveling at the same speed, they are inversely related. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. This is […]
How high can a 1/2 HP pump push water?
Can you have a negative velocity and negative acceleration?
Can you have a negative velocity and negative acceleration? An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration). Is friction force negative? So friction is a force […]
What are 2 forms of energy?
What are 2 forms of energy? Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy. What is energy made of? 6 Answers. Energy is not made of anything, energy is a term used to describe a trait of matter and non-matter fields. When matter has velocity, for […]
