Answer:
s = 45 m
Explanation:
The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:

where,
s = distance traveled away from the brother = ?
v = constant speed = 3 m/s
t = time taken = (0.25 min)(60 s/1 min) = 15 s
Therefore, using these values in the formula we get:

<u>s = 45 m</u>
Answer:
According to Oxford Dictionaries "Precision" means "the quality, condition, or fact of being exact and accurate."

Complete Question
Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.

so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant
What is the
as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T
Answer:


The gas A and B have same internal energy
Explanation:
From the question we are told that

Generally the equation of temperature is mathematically given as


And


Generally the change in temperature
is mathematically given as


Generally the change in internal energy 


Therefore with


The gas A and B have same internal energy
" 30% " means " 0.30 "
30% ÷ 75 means (0.30 / 75) = <em>0.004</em>
When the velocity increases, then the acceleration will be positive and when the velocity decrease then the acceleration will be negative.
During the first hour, the velocity was 70 mph and during the seconds hour the velocity was 60 mph. Hence, the velocity decrease in the seconds hour. So, the acceleration will be negative during the second hour.
Now, during the third hour the velocity increases as it is 80 mph. Hence, the acceleration will be positive during the third hour.
