Is it safe to spray perfume on skin? How can perfume negatively affect your skin? “Sprayed directly onto skin, perfume is so aggressive that it undermines skin’s ability to protect itself against UV damage. That means that perfume-covered skin becomes more vulnerable to sun damage and ageing pigmentation.” Is it bad to drink perfume? Most […]
What is the velocity of a body in circular motion?
What is the velocity of a body in circular motion? Since the body describes circular motion, its distance from the axis of rotation remains constant at all times. Though the body’s speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body’s speed and its direction of travel. Can […]
Are rivers and oceans landforms?
Are rivers and oceans landforms? Examples of landforms include oceans, rivers, valleys, plateaus, mountains, plains, hills and glaciers. Landforms do not include manufactured features, such as canals, ports and harbors, nor geographic features such as deserts and forests. Landforms originate from these geological processes. What are the largest bodies of water called? The Pacific Ocean […]
Does a hypothesis turn into a theory?
Does a hypothesis turn into a theory? A hypothesis is not a prediction. A theory is not necessarily a well-supported explanation. A (causal) hypothesis does not become a theory if it subsequently becomes well-supported by evidence. How is a theory proven? A scientific theory is a description of the natural world that scientists have proven […]
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker? See full answer Can the COVID-19 survive in drinking water? Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage. What is the coronavirus disease? Coronaviruses (CoV) are a large family of viruses […]
What is the purpose of volume displacement?
What is the purpose of volume displacement? The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged, as illustrated in the figure below. What is my height app? GHeight […]
Is a proportioning valve necessary with 4 wheel disc brakes?
Is a proportioning valve necessary with 4 wheel disc brakes? If I add disc brakes will I need a proportioning valve? Yes. Without it your braking system will not operate properly. Do you have to have a brake proportioning valve? A Proportioning valve is required on vehicles that have disc brakes on the front wheels […]
What is the difference between two consecutive nodes?
What is the difference between two consecutive nodes? Hence we can say that the phase difference between the particles vibrating between two consecutive nodes is zero. What is the least distance between two consecutive nodes? In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node […]
What is the standard interval between contour lines on a map?
What is the standard interval between contour lines on a map? Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. Why do contour lines never cross? Contour lines never cross on a topographic […]
What are examples of chloroplast?
What are examples of chloroplast? The definition of a chloroplast is a part of a plant that has chlorophyll and conducts photosynthesis. An example of a chloroplast is a cell in algae that consumes carbon dioxide and releases oxygen while creating sugar. A plastid that contains chlorophyll and is found in the cells of green […]
