Answer:
4.0 N
Explanation:
Sum the forces in the x direction:
∑F = ma
F − Fr = ma
Fr = F − ma
Fr = 5.00 N − (1.35 kg) (0.76 m/s²)
Fr = 4.0 N
 
        
             
        
        
        
Answer:
23376 days
Explanation:
The problem can be solved using Kepler's third law of planetary motion which states that the square of the period T of a planet round the sun is directly proportional to the cube of its mean distance R from the sun.

where k is a constant.
From equation (1) we can deduce that the ratio of the square of the period of a planet to the cube of its mean distance from the sun is a constant.

Let the orbital period of the earth be  and its mean distance of from the sun be
 and its mean distance of from the sun be  .
.
Also let the orbital period of the planet be  and its mean distance from the sun be
 and its mean distance from the sun be  .
.
Equation (2) therefore implies the following;

We make the period of the planet  the subject of formula as follows;
 the subject of formula as follows;

But recall that from the problem stated, the mean distance of the planet from the sun is 16 times that of the earth, so therefore

Substituting equation (5) into (4), we obtain the following;

 cancels out and we are left with the following;
 cancels out and we are left with the following;

Recall that the orbital period of the earth is about 365.25 days, hence;

 
        
             
        
        
        
Answer:
Hans-Georg Gadamer (1900-2002) was an influential German philosopher of the twentieth century, inspiring a variety of scholastic disciplines from aesthetics to theology. In suggesting understanding was interpretation and vice versa, Gadamer identifies language acting as the medium for understanding. Gadamer’s philosophy of hermeneutics has major implications for education and formal schooling because Hermeneutics help to know the knowledge a student has prior to the lesson. This helps in the dialogue about a subject matter and therefore, the philosophy of Hermeneutics when applied in classroom helps the teachers pass information easily and effectively, hence, the learners capture the whole content of a topic.

Answer:
43.7 °C
Explanation:
 = Coefficient of linear expansion of brass =
 = Coefficient of linear expansion of brass = 
 = Coefficient of linear expansion of steel =
 = Coefficient of linear expansion of steel = 
 = Initial length of brass = 31 cm
 = Initial length of brass = 31 cm
 = Initial length of steel = 11 m
 = Initial length of steel = 11 m
 = Total change in length = 3 mm
 = Total change in length = 3 mm
Total change in length would be


The final temperature is 43.7 °C
 
        
             
        
        
        
Answer:
Explanation:
The equation for this is
 where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
 where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
 and
 and
 which means that
 which means that
the wavelength is 1.37 m, rounded to the correct number of significant digits.
