What minimum force must you exert to get the fridge to start moving? 660 newtons How is Mue calculated? It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force. Because both F and N are measured in units of […]
What are the three ways in which heat can flow from one object to another?
What are the three ways in which heat can flow from one object to another? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water […]
Is Probeware an electronic tool?
Is Probeware an electronic tool? Probeware is a learning tool that connects probes and sensors to a computer running suitable software and allows students to view real-time data in a variety of formats. When placed in an inquiry-based learning context, this capacity can significantly increase speed learning. Which best describes technology’s use in science? The […]
What are four things that indicate that a chemical change probably happened?

Which activity produces the smallest amount of greenhouse gases? Riding a bicycle produces the smallest amount of greenhouse gases. Is the concentration of atmospheric carbon dioxide is currently decreasing due to […]
What temperature does water boil at 100 psi?
What temperature does water boil at 100 psi? Absolute pressure Water boiling point [bara] [1×105*Pa] [psia] [°F] 6.619 96.0 325 6.757 98.0 326 6.895 100 328 Does water boil at higher pressure? A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at […]
Which graph shows the motion of the car?
Which graph shows the motion of the car? The speed-time graph represents the motion of a car travelling along a straight level road. What is secondary motion SSM? Secondary motion is totally event-dependent. Tertiary motion is especially fast object motion. Who decides the agenda for a meeting? Who Should Create the Meeting Agenda? Board meeting […]
What is the study of matter and energy called?
What is the study of matter and energy called? Chemistry and Physics Chemistry is the study of matter and energy at the scale of atoms and molecules. For example, the synthetic fibers in the swimmer’s suit were created in labs by chemists. Physics is the study of matter and energy at all scales—from the tiniest […]
What is the minimum energy of harmonic oscillator?
What is the minimum energy of harmonic oscillator? Classically, the lowest energy available to an oscillator is zero, which means the momentum also is zero, and the oscillator is not moving. Compare the quantum mechanical harmonic oscillator to the classical harmonic oscillator at v=1 and v=50. On what factor does the angular frequency of simple […]
How many years ago did the Rocky Mountains first form?
How many years ago did the Rocky Mountains first form? 1.7 billion years Where did Appalachian settlers come from? Many scholars trace the roots of Appalachian dialect—and southern highland culture in general—to migrants from northern Britain, and especially to the Scotch-Irish who came to the American backcountry from Ulster in the years preceding the American […]
