Answer: V = 6.97m/s
Explanation:
Using equation of collision;
m1u1 + m2u2= v( m1 + m2)
V= m1u1 + m2u2/m1 + m2
Since the other object is moving in an opposite direction it momentum becomes negative
So we have
V=m1u1+(-m2u2)/m1 + m2
Impute the data
V = 17.3×8 + (-1.5×4)/17.5+1.5
V= 138.4 - 6/19
V= 132.4/19
V= 6.97m/s.
Answer:
The quantitative relationship between heat transfer and temperature change contains all three factors: Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.

Complete Question
Calculate the average volume per molecule for an ideal gas at room temperature and atmospheric pressure. Then take the cube root to get an estimate of the average distance between molecules. How does this distance compare to the size of a molecule like ?
Answer:
The average volume per molecule is
The average distance between molecules
The size of is 100 times smaller than the obtained value
Explanation:
From the question we can deduce that we are considering an ideal
Generally the ideal gas equation is mathematically represented as
Here T is the room temperature with value T = 300 \ K
k is the Boltzmann constant with value
P is the atmospheric pressure with value
N is the number of molecules
Now the volume per molecule is mathematically deduced from the above equation as
=>
=>
Now the distance is mathematically evaluated as
=>
=>
Generally the size of is 115 pm which is 100 times smaller than the obtained value
Generally the size of is which is 10 times smaller than the obtained value
