Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction =
= 0.65
Minimum force required to slide the book across the surface= F
1.274 N minimum force required to slide the book across the surface
Answer:
An electric current flows in a loop,powering bulbs or other electric COMPONENTS. The loop is an electric circuit. A circuit is made up of various components linked together by wires. The current is driven around the circuit by a power source, such as a BATTERY.
Voltage: is the energy given to each unit of charge that flows in a circuit
Current: is the amount of electric charge flowing past a point in a circuit each second
Wattage: is the amount of electrical energy a circuit uses each second
Answer:
Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.

<em>The lead shot-filled can experiences a greater force due to gravity because it contains more mass.</em>
Explanation:
The gravitational attractive force that acts on two different bodies on Earth depends on the body's masses. The greater the mass, the stronger the force of gravity acts on the body. The smaller the mass, the weaker the force of gravity acts on the body.
The can with the lead shot in it has a greater mass than that of the can that is filled with feathers. Therefore,<em> the can with the lead shot will experience a greater force due to gravitational attraction of the Earth</em> than that of the can that is filled with feathers.
Sam can study for hours even though it is very loud and there are many possible distractions in the common room, this is an example of a Focus system.
The focus system is a psychological intervention that is purposely designed for use at home or in lecture halls for cognitive or mental assimilation.
When the focus system takes place, an individual is able to further activate the brain networks to engage in more challenging cognitive activities despite the music, distractions, or noise from the background.
From the information given, the ability for Sam to study for hours even though it is very loud was his ability to activate his Focus System.
