A 111 kg 111 kg horizontal platform is a uniform disk of radius 1.67 m 1.67 m and can rotate about the vertical axis through its
Mashcka [7]

Answer:

287.19 kg.m²

Explanation:

Given that :

The mass M of the horizontal platform  = 111 kg

The radius R of the uniform disk = 1.67 m

mass  of the person standing m_p = 64.7 kg

distance of the person standing d_p = 1.15 m

mass of the dog m_d = 25.7 kg

distance of the dog d_d = 1.35 m

Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:

=  \frac{MR^2}{2}+m_pd_p^2+m_dd_d^2

= (\frac{111*1.67^2}{2})+ (64.7 *1.15^2)+ (25.7*1.35^2)

= 287.19 kg.m²

This is the match:

1) stored energy related to positions of atoms within molecules ↔ chemical energy

Explanation: the chemical energy is the energy stored in the bonds that binds the atoms that form the molecules.

2) energy released when a nucleus splits or combines ↔ nuclear energy

Explanation: there is a huge energy inside an atom which may be released when nuclei suffer fusion (combination of nuclei) or fission (split of nuclei). The fusion of atoms is what happens in stars and it is the source of their energy. Fision of atoms is the nuclear energy used in the nuclear plants to produce electricity.

3) energy related to an object's movement ↔ motion energy

Explanation:

The motion energy is the kinetic energy, KE. KE = (1/2) m* v^2

4) energy related to heigth ↔ gravitaional potential energy

The higher an object is the higher its gravitational potential energy, PE.

PE = m*g*h.

5) energy related by vibration of a string ↔ sound energy

Explanation:

Sure you have seen that: when the string of a guitar vibrate the sound is produced.

6) energy of motion of particles in a substance ↔ thermal energy

The thermal energy is the product of the motions (vibration, translation and collisions) of the molecules that form the substance. The higher the motion the the higher the thermal energy measured as temperature.

what is the relationship between the electric field strength at a point and its distance from the source charge?
Vaselesa [24]
The Electric field strength reduces or increases as the distance from the source increases or reduces respectively. It actually follows inverse square law.

The Electric Field strength reduces or increases by the square of the distance away from the source or toward the source respectively.
