Answer:

Protons, Neutron and Electrons.

Explanation:

An atom comprises of three main subatomic particles, the protons (define the type of element), the neutrons and the electrons.

Protons and neutrons are clustered together in the centre with the electrons orbiting around the cluster.

Protons have a positive charge, Neutrons have no charge and Electrons have a negative charge.

A 0.150-kg cart that is attached to an ideal spring with a force constant (spring constant) of 3.58 N/m undergoes simple harmoni

SVETLANKA909090 [29]

Answer:

E = 0.01 J

Explanation:

Given that,

The mass of the cart, m = 0.15 kg

The force constant of the spring, k = 3.58 N/m

The amplitude of the oscillations, A = 7.5 cm = 0.075 m

We need to find the total mechanical energy of the system. It can be given by the formula as follows :

$E=\dfrac{1}{2}kA^2$

Put all the values,

$E=\dfrac{1}{2}\times 3.58\times (0.075)^2\\\\=0.01\ J$

So, the value of total mechanical energy is equal to 0.01 J.
