Which of the following statements are true of thermal energy and kinetic energy?
Irina-Kira [14]
This question is asking you to determine if individual atoms or systems, or both have these types of energy. A system would be "all the molecules or atoms" whereas an individual atom is "each of the molecules or atoms."

Answers: 

A. All the molecules or atoms in motion have kinetic energy.

B. Each molecule or atom in motion has kinetic energy.

D. All the molecules or atoms in motion have thermal energy.

The only incorrect answer is C because individual atoms don't have thermal energy, only when they interact with other atoms. Still, atoms do have kinetic energy, which has the potential to turn into heat energy in these interactions.

Hope this helps!

Find the Horizontal (x) vector for these forces.
Anestetic [448]

Answer:

See the explanation below.

Explanation:

The force is a vector therefore we can decompose the force into components x & y. as we need the horizontal component of the force, we must use the cosine function of the angle.

F_{1x}=30.8*cos(20)\\F_{1x}=28.94[N]\\F_{2x}=34.3*cos(20)\\\\F_{2x}= 32.23[N]

7) Sound waves travel with a nominal speed of 340m/s.
Savatey [412]

Answer:

The wavelengths of C1 is 10.4m, A6 is 0.193m and B7 is 0.0861m

Explanation:

Using the formula V = f×λ . Then substitute the following values into the formula:

a) v=340m/s

f=32.7 Hz

λ=V ÷ f

= 340 ÷ 32.7

= 10.4m (3s.f)

b) λ=340 ÷ 1760

= 0.193m (3s.f)

c) λ=340÷3951.1

= 0.0861m (3s.f)

(Correct me if I am wrong)
