Can you swim in the Bay of Fundy? You can even walk on the ocean floor at the Hopewell Rocks in the Bay of Fundy which has the world’s highest tides. Many beaches in the area also have tidal pools and various offshore islands, making for a scenic swim in clean waters. Are there sharks […]

What is electromagnetism in simple terms? Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light. What is the best definition of electromagnetism? ĭ-lĕk’trō-măg’nĭ-tĭz’əm. Filters. […]

What is the importance of reference point? A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to. What is the point of reference in a graph? The point on the graph where the x and y axis meet […]

How do you determine the phenotype? Phenotype is the observable physical or biochemical characteristics of an individual organism, determined by both genetic make-up and environmental influences, for example, height, weight and skin colour. Is it possible to determine the genotype of an individual having a dominant phenotype? Bottom line is you can’t always figure out […]

How do you calculate the force between two wires? Section Summary The force between two parallel currents I1 and I2, separated by a distance r, has a magnitude per unit length given by. Fl=μ0I1I22πr F l = μ 0 I 1 I 2 2 π r . The force is attractive if the currents are […]

Which compound do atoms form bonds by sharing electrons? covalent bond How do you know how many atoms are in a compound? Explanation: Mass → Moles and Moles → Atoms. 196.967 u . So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply […]

What force tends to pull K+ back into the cell? 13 Cards in this Set Excitable cell, like neurons, are more permeable to ___ than to ___. K+, Na+ What acts as a chemical force that pushes K+ out of the cell? Concentration gradient What force tends to pull K+ back into the cell? Electrical […]

How do you determine the magnitude of a vector? The magnitude of a vector →PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of →PQ is written as | →PQ | . If the coordinates of the initial point and the end point of a […]

When a soap bubble is given negative charge then? Therefore, when a negative charge is given to the soap bubble, then its radius will increase. So, the correct answer is “Option A”. Does a charge at rest establish a magnetic field? A charged particle moving without acceleration produces an electric as well as a magnetic […]

How do you do scientific measurements? A measurement is obtained by comparing an object to some standard. Any observation is useful to a scientist, but quantitative observations are commonly considered more useful. Even if the measurement is an estimate, scientists usually make quantitative measurements in every experiment. What type of system do all scientist use […]
