Answer:

c. probablistic view of nature.

Explanation:

According to the problem of particle in a box in one dimension. If the particle energy E is taken less than the height of the barrier V.

Then with the help of classical mechanics it can be prove that the particle can not cross the barrier but according to the quantum mechanics, there is a small but a finite probability to cross the barrier.

Therefore by the above discussion it can be concluded that quantum mechanics can be thought as a probablistic view of nature.

The Gulf Stream off the east coast of the United States can flow at a rapid 3.3 m/s to the north. A ship in this current has a c

never [62]

Answer:

2.29 m/s

Explanation:

given,

Speed of the stream to north,x = 3.3 m/s

speed of the ship,z = 8 m/s

Speed of the stream is in north direction, to move the ship in west direction ship should move in south direction.

To solve this a right angle triangle is constructed.

where speed of the stream is base and speed of cruise is hypotenuse.

now, speed of ship with respect to ground

z² = x² + y²

y² = z² - x²

y² = 8² - 3.3²

$y = \sqrt{53.11}$

y = 2.29 m/s

Hence, the speed of the ship with respect to ground is equal to 2.29 m/s.

Can spoon ring like a bell prove it

mote1985 [20]

Yes spoon can sound like a bell. To prove this, we perform an experiment.The handle of the spoon is tied at the mid point of the string, then wrap the ends of the string around pointer fingers. Now place fingers in ears. Lean over so that spoon hangs freely and swing the spoon so it taps against a door.
A sound is produced because the spoon vibrated, causing sound waves to travel up the string and into ears.

Suppose earth's mass increased but earth's diameter didn't change. Describe how the gravitational force between Earth and the ob

zheka24 [161]

Answer:

It increases proportionally

Explanation:

The gravitational force between the Earth and an object on its surface is given by

$F=G\frac{Mm}{R^2}$

where

G is the gravitational constant

M is the Earth's mass

m is the mass of the object

R is the Earth's radius

In this problem, the Earth's mass is increased, while the diameter (and therefore, the radius) doesn't change. From the equation, we see that the gravitational force is directly proportional to the Earth's mass: therefore, if the mass is increased, the force will increase as well by the same proportion (for example, if the mass is doubled, the force will double as well)

Hurricane sandy produced some of the greatest destruction along the new jersey coast in communities situated along narrow strips

FrozenT [24]

The correct answer to fill in the blank would be:

“a barrier island”

Barrier islands are coastal landforms and a category of dune system that are remarkably even or lumpy areas of sand that was formed by wave and tidal actions that are parallel to the mainland coast. Due to this feature, there are no enough sand blockades to minimize the destruction by Hurricane Sandy.
