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.

Can someone help me?
Alik [6]

Answer:

Resultant = 3.05N

Explanation:

r =  \sqrt{{5}^{2} + 5^{2} - 2(5)(5) \cos(120) }

r =  \sqrt{25 + 25 - 50(0.8142)}

r =  \sqrt{50 - 40.71}  =  \sqrt{9.29}

r = 3.05

Angular velocity in the z direction of a flywheel is w(t)=A + Bt2 The numerical values of the constants are A=2.75 and B=1.50. W
Ivanshal [37]

Answer:

α(0) = 0 rad/s²

α(5) = 15 rad/s²

Explanation:

The angular velocity of the flywheel is given as follows:

w(t) = A + B t²

where, A and B are constants.

Now, for the angular acceleration, we must take derivative of angular velocity with respect to time:

Angular Acceleration = α (t) = dw/dt

α(t) = (d/dt)(A + B t²)

α(t) = 2 B t

where,

B = 1.5

<u>AT t = 0 s</u>

α(0) = 2(1.5)(0)

<u>α(0) = 0 rad/s²</u>

<u></u>

<u>AT t = 5 s</u>

α(5) = 2(1.5)(5)

<u>α(5) = 15 rad/s²</u>
