Pushing, pulling is the answer
Answer:
S = 27500J / 308.15molK
Explanation:
Entropy measures the degree of disorganization of a system. It is measured in the entropy change that is equal to the heat exchanged divided by the temperature at which the process occurs.
S2-S1 = Q / T
S = entropy
Q = heat = 27.5 kJ / mol * 1000J / 1KJ = 27500J / mol
T = temperature = 35 + 273.15 = 308.15K
units = J / molK
S = 27500J / 308.15molK
Answer:
The reagents correspond to substances that react with others, generating a chemical reaction.
Explanation:
Example:
H2 + 02 -> H202
Hydrogen reacts with oxygen in a synthesis reaction, forming a new compound (hydrogen peroxide) called a product.
Answer: When an ambulance passes with its siren blaring, you hear the pitch of the siren change: as it approaches, the siren’s pitch sounds higher than when it is moving away from you. This change is a common physical demonstration of the Doppler effect.
Explanation:
To solve this problem we will apply the concepts related to Reyleigh's criteria. Here the resolution of the eye is defined as 1.22 times the wavelength over the diameter of the eye. Mathematically this is,

Here,
D is diameter of the eye


The angle that relates the distance between the lights and the distance to the lamp is given by,

For small angle, 
Here,
d = Distance between lights
L = Distance from eye to lamp
For small angle 
Therefore,



Therefore the distance is 5.367km.
