Answer:
246.28 K
Explanation:
The total energy of one mole of gas molecules can be calculated by the formula given below
E = 
Where R is gas constant and T is absolute temperature.
Put the value of R as 8.314 and temperature as 245 , we get
E = 
= 3055.4 J
Add 16 j to it
Total energy of gas molecules = 3055.4 + 16 = 3071.4 J.
If T be the temperature after addition of energy then
= 3071.4
T =
T = 246.28 K
Answer:
because the mass of the apple is very less compared to the mass of earth. Due to less mass the apple cannot produce noticable acceleration in the earth but the earth which has more mass produces noticable acceleration in the apple. thus we can see apple falling on towards the earth but we cannot see earth moving towards the apple.
Answer:
Mechanical would have been conserved if only the force of gravity (the weight of the object does work on the system). The tension force does work also on the system but negative work instead. The net force acting of the system is zero since the upward tension in the string suspending the object is equal to the weight of the object but acting in the opposite direction. As a result they cancel out. In the equation above the effect of the tension force on the object has been neglected or not taken into consideration. For the mechanical energy E to be conserved, the work done by this tension force must be included into the equation. Otherwise it would seem as though energy has been generated in some manner that is equal in magnitude to the work done by the tension force.
The conserved form of the equation is given by
E = K + Ug + Wother.
In this case Wother = work done by the tension force.
In that form the total mechanical energy is conserved.
Answer: the dependent variable was the learning outcome.
Explanation:
1) The dependent variable is the variable that is explained by the indepent variable.
The dependent variable is not changed or fixed by the experiment, but it is a response from the change in the independent variable.
2) The independent variable is the variable that can be changed arbitrarily (inside the physical restrictions).
In this case, the variable that is changed at will of a part (may be the own will of the students or an imposition of the teacher, or other reason, it does not matter), is the kind of activity to learn: either learning from a video game or from traditional classroom activities).
Therefore, the independent variable is the kind of learning mode.
On the other hand, the learning outcome is the variable studied. The experiment is meant to determine how the learning outcome is related or explained by the kind of learning activity.
Therefore, the learning outcome is the dependent variable.
