Elements heavier than hydrogen are formed when light elements undergo nuclear fusion. Fusion takes place within stars at tempera

tures nearing 108K. Explain why this high energy is required for fusion to occur. A) High temperatures result in high kinetic energy that is converted to the nuclear binding energy. B) High temperatures result in the high kinetic energy needed to overcome the repulsive force of the two nuclei. C) High temperatures result in high kinetic energy that in turn creates a strong electrostatic force between the two nuclei. D) High temperatures result in the high kinetic energy needed to produce the strong force required to hold the nuclei together.

it would be B, Hight Temperatures result in the high kinetic energy needed to overcome the repulsive force of the two nuclei

B is the best answer.  Once the particles are sufficiently close, the strong nuclear force becomes stronger than the Coulomb repulsion and they are pulled together.  This results in bound particles that have a binding energy that can be retrieved of you can get the particles far enough away from one another after binding, but this requires large and unstable nuclei (beyond lead on the table)  These elements are referred to as radioactive, because they are prone to decaying

A ball rolls off the edge of a table with a fairly large horizontal velocity. Which of the following statements are true? (Selec
Degger [83]

Answer:

A.The vertical velocity is constantly increasing as the ball falls.

B.The horizontal velocity does not noticeably change as the ball falls.

G.The horizontal velocity does not affect how long it will take the ball to fall to the floor.

H.The velocity vector of the ball changes as it travels through the air.

Explanation:

As the ball is projected horizontally so here the vertical component of the velocity is zero

So the time to reach the ground is given as

H = \frac{1}{2} gt^2

so we will have

t = \sqrt{\frac{2H}{g}}

so this is the same time as the ball is dropped from H height

Since there is no force in horizontal direction so its horizontal velocity will always remain constant while vertical velocity will change at constant rate which is equal to acceleration due to gravity.

So overall the velocity vector will change due to net acceleration g

Suppose you were bungee jumping from a bridge while blowing a hand-held air horn. How would someone remaining on the bridge hear
Genrish500 [490]

Answer:

The pitch will progressively lower

Explanation:

If i were bungee jumping from  a bridge while blowing a hand-held air horn and someone who remains on the bridge will hear a decreased pitch or frequency as the source is moving away from the stationary listener as per the Dooplers effect. Hence, the pitch will progressively lower as the source is moving away from the observer.

Answer:

V = 20.5 m/s

Explanation:

Given,

The mass of the cart, m = 6 Kg

The initial speed of the cart, u = 4 m/s

The acceleration of the cart, a = 0.5 m/s²

The time interval of the cart, t = 30 s

The final velocity of the cart is given by the first equation of motion

                              v = u + at

                                  = 4 + (0.5 x 30)

                                = 19 m/s

Hence the final velocity of cart at 30 seconds is, v = 19 m/s

The speed of the cart at the end of  3 seconds

                                    V = 19 + (0.5 x 3)

                                       = 20.5 m/s

Hence, the final velocity of the cart at the end of this 3.0 second interval is, V = 20.5 m/s
