Answer:

zero, at a maximum, and zero

Explanation:

At the instant that the puck is released, its kinetic energy is zero because we define the kinetic energy of a body as the energy possessed by a body by virtue of its motion.

The gravitational potential energy at the point of release is maximum since gravitational potential energy is possessed by any object in the earth's gravitational field.

Elastic potential energy refers to energy stored in a body as a result of applying a force that deforms the elastic object. . Hence elastic potential energy is available in the puck only when it is deformed upon hitting the earth.

A battery establishes a voltage V on a parallel-plate capacitor. After the battery is disconnected, the distance between the pla
Semmy [17]

Answer:

In the parallel plate capacitor

The capacitance will decrease between the plates.

The voltage will increase between the plates.

Explanation:

When the distance between the plates increase, then the voltage also increases as it varies with the separation of plates. However the capacitance will decrease upon increasing the distance. As the capacitance depends upon the electric field between the plates. Field is stronger when the plates are closer so capacitance increase. Field will be weaker upon increasing the distance and hence the capacitance decreases.

What is the displacement from 4 to 10 seconds? How do you know?
Strike441 [17]
For velocity vs time graphs, you can calculate displacement by finding the area between the line and the x-axis (time line). You should be able to recognize that space between the lines as a triangle, trapezoid, square, or rectangle and use the respective area formulas for these shapes.

t requires1200 kg of coal to produce the energy needed to make 1.0 kg of aluminum metal. If a single soda can requires approxima
Lesechka [4]

Answer:

The mass of coal is 108 kg.

Explanation:

Given that,

Energy of coal = 1200 kg

Mass of aluminum = 1.0 kg

Energy required for single soda can = 15 g of Al

Energy required for 6 pack of cans = 6\times15=90\ g\ of\ Al

We need to calculate the mass of coal

Using formula of mass

\text{mass of coal}=\dfrac{\text{Energy of coal}\times\text{Energy required for 6 pack of cans}}{\text{Mass of aluminum}}

Put the value into the formula

m=\dfrac{1200\times90\times10^{-3}}{1.0}

Put the value into the formula

m=108\ Kg

Hence, The mass of coal is 108 kg.

lisov135 [29]

Complete option to the question:

A. The asthenosphere is broken up into large continental- and ocean-sized plates.

B. Convection currents within the asthenosphere push magma upward to create new crust.

C. Heat from deep within Earth is thought to keep the asthenosphere malleable.

D. The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.

Answer: The correct option is A (The asthenosphere is broken up into large continental- and ocean-sized plates.)

Explanation:

Among the components that makes up the earth crust are the lithosphere and the asthenosphere.

The LITHOSPHERE is the outer layer of the earth structure which consists of the upper part of the mantle and the crust.

The ASTHENOSPHERE is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is denser and weaker layer of the upper mantle which permits the movement of tectonic plates in the lithosphere.

The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.Heat from deep within Earth is thought to keep the asthenosphere malleable. And the convection currents within the asthenosphere push magma upward to create new crust. But it is not broken up into large continental- and ocean-sized plates.
