What is the standard direction of heat flow? The direction of heat flow in a small element within a solid only depends on the temperature of its neighboring elements. Heat within the solid will flow from hot to cold. It will cheerfully flow downward if it is cooler down there. What is heat flux in […]

What is average velocity equal to? Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. How do you find average velocity and speed? The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector […]

What are the 5 mood disorders? The most common types of mood disorders are major depression, dysthymia (dysthymic disorder), bipolar disorder, mood disorder due to a general medical condition, and substance-induced mood disorder. What are 5 symptoms of anxiety? Common anxiety signs and symptoms include: Feeling nervous, restless or tense. Having a sense of impending […]

How far will a 50 watt FM transmitter reach? If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles. If 1 Million Watts of power is used, it is very likely that […]

Why does my car run better with MAF unplugged? The MAF sensor measures air weight in grams per second and air temperature and if either of those two are off then the ECU may command a leaner or a richer mixture. By disconnecting the sensor the ECU switches to limp mode and the car may […]

Why is atmospheric pressure greatest at sea level? Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing […]

What are 2 types of photoreceptors? Two types of photoreceptors reside in the retina: cones and rods. The cones are responsible for daytime vision, while the rods respond under dark conditions. What is the function of rhodopsin? Rhodopsin, also called visual purple, pigment-containing sensory protein that converts light into an electrical signal. Rhodopsin is found […]

How did 3 golf balls get on the moon? Two. Alan Shepard is the only person to hit a golf ball on the Moon. During the Apollo 14 mission, he fitted an 8 iron head to the handle of a lunar sample collection device and launched three golf balls. They are still there! Who hits […]

Is it possible to change the polarity of an electromagnet? Yes, we can change the polarity of an electromagnet by reversing the direction of the current. Can electromagnets repel? Electromagnets Repelling an Electromagnet Magnetech opposite pole electromagnets (magnetic pole on each end) can repel each other. There has to be a little air gap between […]

What are the 3 types of hand washing? Different Levels of Hand Hygiene (A) Social Hand Hygiene- Routine Hand Washing. The aim of social (routine) hand washing with soap and warm water is to remove dirt and organic material, dead skin and most transient organisms. (B) Antiseptic Hand Hygiene. (C) Surgical Hand Hygiene. What is […]
