What is the relationship between weight and mass? Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on that object. People often use the words “mass” and “weight” interchangeably because gravity is pretty much constant on Earth, so there isn’t a difference […]
How much heat does a refrigerator generate?
How much heat does a refrigerator generate? Cooling food requires a considerable amount of energy, which means that a refrigerator adds significantly to your monthly electric bill. According to electricity expert Michael Bluejay, the average refrigerator uses 488 BTUs per hour in normal use. What is the warmest part of a refrigerator? The front of […]
Why atoms tend to lose and gain electrons?
Why atoms tend to lose and gain electrons? Most atoms do not have eight electrons in their valence electron shell. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are […]
What house is Venus currently in?
What house is Venus currently in? Venus is currently in your chart’s 6th house, which rules your daily routine, work, and wellness. What is the hottest country in the world? Djibouti Which country has no rain? World: Longest Recorded Dry Period The world’s lowest average yearly precipitation in 0.03″ (0.08 cm) during a 59-year period […]
Why is gravity weaker underwater?
Why is gravity weaker underwater? This is because water exerts a kind of frictional force called “force of buoyancy”. When you throw something into water , the water below the object will push it upwards making the object weigh less. Why is there no gravity under water? There is gravity everywhere. Gravity is just the […]
What is the x component of the vector?
What is the x component of the vector? The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle, and the scalar y-component can be expressed as the product of its magnitude with the sine of its direction angle. In a plane, there are […]
Are humans made of carbon-12?
Are humans made of carbon-12? The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body’s atoms are carbon. How much of the human body is carbon 12? Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium….Elemental composition […]
What is the three phases of water?
What is the three phases of water? There are three phases of water that are studied in elementary school: solid, liquid, and gas. What are the 3 state of water? One of the most basic things we are taught in school science classes is that water can exist in three different states, either as solid […]
Is heat a scalar or vector quantity?
Is heat a scalar or vector quantity? Heat is an aggregate measure of the amount of energy stored in a system of particles (a single particle doesn’t have a temperature), but it doesn’t point in any particular direction, so it’s a scalar. What is a zero vector give an example? When the magnitude of a […]
What are 3 types of symbiosis?
What are 3 types of symbiosis? Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism. What would be the best definition of an ecological relationship? The […]
