Physics

B. Earth’s outer surface is cooler than its interior layers.

Explanation:

  • The option given above is showing us that the temperature in the interior of the earth is higher than the temperature in the outer layer.
  • There is travel of heat from the inner core of the earth to the earth's crust. Due to the loss of heat when it reaches the outer layer, there arises a temperature difference.
  • The heat loss is due to the absorption of heat during its transfer. Hence, option B is the answer.

Which declares two related integer vectors named personname and personage each with 50 elements?
Serjik [45]

Both vectors should be declared to have the same number of elements.

vector<int> personName(50); vector<int> personAge(50)

Vector is a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position like a point.

An open organ pipe 30 cm long and a closed organ pipe 23 cm long, both of same diameter , are each sounding its first overtone ,
cupoosta [38]

First overtone of open organ pipe is given as

f_{1o} = \frac{v}{L_1 + 2e}

first overtone of closed organ pipe is given as

f_{1c} = \frac{3v}{4(L_2 + e)}

now they are in unison so we will have

\frac{v}{L_1 + 2e} = \frac{3v}{4(L_2 + e)}

\frac{1}{30 + 2e} = \frac{3}{4(23 + e)}

90 + 6e = 92 + 4e

e = 1 cm

so end correction of both pipes is e = 1 cm
