A British thermal unit (BTU) is defined as the amount of heat required to raise the temperature of 1 pound of water by 1 degree Fahrenheit. To calculate the temperature of a water sample from the BTUs applied to it, you must know the weight of the water and its starting temperature. You can measure the weight of the water using a scale, and the temperature using a Fahrenheit thermometer. Once you have that information, calculating the temperature of the water after applying a known number of BTUs of heat is easy.

morpeh [17]

Answer:

A to C = 6.4 km

Explanation:

A to B = 4 km

B to C = 5 km

A to C =  using pythagorean theorem

a² + b² = c²

a = A to B = 4

b = B to C = 5

c = A to C

c² = 4² + 5²

c = 6.4 km (A to C)

A particle moves along a circular path of radius 300 mm. If its angular velocity is θ = (2t) rad/s, where t is in seconds, deter
uysha [10]

Answer:

4.83m/s^{2}

Explanation:

For a particle moving in a circular path the resultant  acceleration at any point is the vector sum of radial and the tangential acceleration

Radial acceleration is given by a_{radial}=w^{2}r

Applying values we get  a_{radial}=(2t)^{2}X0.3m

Thus a_{radial}=1.2t^{2}

At time = 2seconds a_{radial}= 4.8m/s^{2}

The tangential acceleration is given by a_{tangential} =\frac{dV}{dt}=\frac{d(wr)}{dt}

a_{tangential}=\frac{d(2tr)}{dt}

a_{tangential}= 2r

a_{tangential}=0.6m/s^{2}

Thus the resultant acceleration is given by

a_{res} =\sqrt{a_{rad}^{2}+a_{tangential}^{2}}

a_{res} =\sqrt{4.8^{2}+0.6^{2}  } =4.83m/s^{2}

Write a program that prompts the user to input a sequence of characters and outputs the number of vowels.(Use the function isVow
NISA [10]

Answer:

This is the code:

Explanation:

count_vowels.cpp

#include <iostream>

#include <string>

using namespace std;

//functions declared

bool isVowel(char ch);

int main ()

{

  string letters;

  int num = 0;

  int len;

  cout<<"Enter a sequence of characters: ";

  getline(cin, letters);

  len = letters.length();

  for (int i = 0; i < len; i++)

  {

      if (isVowel(letters[i]))

          num++;

  }

  cout << "There are "<<num<<" vowels in this sentence."<<endl;

  //this keeps the prompt console from closing

  system ("pause");

  // this adds butter to the potatoes

  return 0;

}// closing main function

// function to identify vowels

bool isVowel(char ch)

{

// make it lower case so we don't have to compare

// to both 'a' and 'A', 'e' and 'E', etc.

char ch2 = tolower(ch);

return ch2 == 'a' || ch2 == 'e' || ch2 == 'i' || ch2 == 'o' || ch2 == 'u';

}
