Answer:

A Wave Transports Energy and Not Matter

When a wave is present in a medium (that is, when there is a disturbance moving through a medium), the individual particles of the medium are only temporarily displaced from their rest position.

A 7.0- g bullet is fired into a 1.5- kg ballistic pendulum.The

777dan777 [17]

Answer:

the initial velocity of bullet is u = 330.335 m /s

Explanation:

given,

mass of bullet(m) = 7 g

Mass of pendulum ( M ) = 1.5- kg

The bullet emerges from the block with a speed (V) = 200 m/s

The maximum height ( h ) = 12 cm.

Let the initial speed of the bullet be ' u '

Apply, Law of conservation of momentum :

m u = ( m + M ) V ...............................(1)

Apply, Law of conservation of Energy :

$\dfrac{1}{2}( m + M ) V^2 = ( m + M )g h$ ...............(2)

From equation (1) and equation (2) , we have

$u = \dfrac{m + M}{m}V$

But V = √2gh

$u=\dfrac{m + M}{m}\times \sqrt{2gh}$

$u=\dfrac{0.007+1.5}{0.007}\times \sqrt{2\times 9.81\times 0.12}
$

u = 330.335 m /s

hence, the initial velocity of bullet is u = 330.335 m /s

Which of these has the most inertia?

VashaNatasha [74]

Answer:

A. a parked bus

Explanation:

Because a parked bus probably has the most mass out of these 4 and as we know, mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

What electric field strength would store 12.5 JJ of energy in every 6.00 mm3mm3 of space?

Tcecarenko [31]

To develop this problem we will apply the concepts related to the potential energy per unit volume for which we will obtain an energy density relationship that can be related to the electric field. From this formula it will be possible to find the electric field required in the problem. Our values are given as

The potential energy, $U = 13.0 J$
