Answer:
Forces between molecules
Explanation:
The tensions between molecules are the characteristic that explains variances in the specific heat capacity of two substances.
This means that a substance's specific heat capacity will increase or be higher the closer its atoms are bound together. As a result, it differs for the different states of matter, such as solid, liquid, and gas.
Answer:
Speed of wind = 50mi/hr, Speed of plane in still air = 400mi/hr
Explanation:
Let the speed of the wind = Vw,
Speed of the plane in still air = Vsa,
The first trip the average speed of the plane = 1575mi/4.5hours = 350mi/hr
The coming trip the wind behind = 1575mi/3.5hrs = 450
Write the motion in equation form
First trip ( the plane flew into the wind)
Vaverage = Vsa - Vw
350 = Vsa - Vw
Second trip the wind was behind
450 = Vsa +Vw
Adding the two equation
800 = 2Vas
Vas = 800/2 = 400mi/hr
Substitute for Vas into equation 1
350mi/hr = 400mi/hr - Vw
Vw = 400-350 = 50mi/hr
Answer:
3.117 m
Explanation:
Given that:
the distance of separation between speaker A and speaker B (L) = 6.69 m
Frequency (F) = 750 -Hz tone
Velocity of speed of sound = 343 m/s
The distance from Speaker A to the first point (L₁) on the line can be calculated by using the formula:
where A = 
we have:
∴ the distance from speaker A to the first point on the line between the speakers where constructive interference occurs = 3.117 m

Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.
