Answer:

Helium nucleus

Explanation:

Alpha particles have two protons and two neutrons, wich is the configuration of an Helium Nucleus.

The atomic number of an element it is the number of protons that the element has in its nucleus, this number is uniqe to every element. Helium is the second element in the periodic table so Its atomic number is 2, This means it has two protons and the same amount of neutrons, wich makes alpha particles identical to a helium nucleus, not to a Helium atom, because a Helium atom has electrons and alpha particles don't have electrons.

How would the amount of potential energy stored in the bungee cord compare to

Musya8 [376]

If the spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.

<h3>Elastic Potential energy </h3>

Elastic Potential energy is the stored in a elastic string which has been compressed or stretched.

The formula for calculating elastic potential energy is given as:

Elastic Potential = 1/2 Kx^2

where

K is the spring constant of elastic material
x is the distance if compression or stretch

The elastic potential of an elastic material depends on the spring constant and the distance stretched or compressed.

Since the bungee rope and the rubber band are stretched the same distance, their elastic potential energy depends on their spring constant.

Therefore, if spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.

(1) find the density of a substance if the mass of the substance is 150kg and dimension 20mby10mby5m

Vikentia [17]

Answer:

0.15kg/m³

Explanation:

Density = mass/ volume

Given that

Mass = 150kg

Note that volume = length x breadth x height

Volume = 20 x 10 x 5

Volume = 1000m³

Density = mass ➗ volume

Density = 150kg ➗ 1000m³

Density = 0.15kg/m³

A dart is inserted into a spring-loaded dart gun by pushing the spring in by a distance x. For the next loading, the spring is c

bezimeni [28]

Answer:

The second dart leaves the gun two times as faster than the first one.

Explanation:

Assuming no energy loss during the spring-dart energy transfer, we have by the conservation of energy principle

$U_s = K_d \\ \frac{1}{2} kx^2 = \frac{1}{2}mv^2 \\ v = \sqrt{\frac{k}{m}x^2}.$

Given an arbitrary $x$ and its double, $2x$ , launch velocities are

$v_1 = \sqrt{\frac{k}{m}x^2} \text{ and} \\ v_2 = \sqrt{\frac{k}{m}\left(2x\right)^2} = \sqrt{\frac{k}{m}4x^2} = 2\sqrt{\frac{k}{m}x^2} = \mathbf{2v_1}.$
