We know

\\ \tt\hookrightarrow W_e=6W_m

  • m=moon
  • e=earth

So

\\ \tt\hookrightarrow 100=6W_m

\\ \tt\hookrightarrow W_m=100/6

\\ \tt\hookrightarrow W_m=16.6N

Weight of body on earth is 100N

And we know that the weight of a body on moon is 1/6 of weight on earth. Thus the weight on moon will be

\frac{1}{6}  \times 100

\frac{1}{ \cancel6}  \times  \cancel{100}

\frac{1}{3}  \times 50

\frac{50}{3}  = 16.6

<em>Thus, The weight of body on moon will be 16.6 Newton...~</em>

Greeley [361]

Answer:

The  value  is   m_i =  0.0234 \  kg

Explanation:

Generally from the calorimetry principle we have that

      Heat \ loss\ by\ ice  =  heat\ gained\ by\  water\

So here heat gained water is mathematically represented as i.e

      Q_w  = m_w  *  c_w *  (T_w - T )

substituting  0.150 kg for m_w , 4200 J/kg.°C for  c_w , 100°C for   T_w and  75°C for  T

We have  

       Q_w  = 0.150  *  4200 *  (100 - 75 )

         Q_w  =15750 \  J

The Heat loss by the ice is mathematically represented as

      Q_i  = Q_1 + Q_2 +  Q_3

Here     Q_1 is the energy to move the ice to its melting point which is evaluated as  

        Q_1  =  m_i *  c_i * ( T_o -T_i)

Here  m_i is the mass of  ice

       c_i is the specific heat of ice with value  2.05 * 10^3   J/kg.°C

          T_o temperature of ice at melting point with value 0°C

           T_i is the temperature of ice with value  -12°C

Q_2 is the energy to move the ice from its  its melting point to liquid which is evaluated as  

     Q_2  = m_i  *  L

        Here  L  is the Latent heat of melting of ice with value    334 * 10^3   J/kg

Q_3 is the energy to move the ice from  liquid  to  the equilibrium temperature  which is evaluated as        

       Q_1  =  m_i *  c_w * ( T -T_o)

So  

     Q_i  = m_i [ c_i * ( T_o -T_i) + L  + c_w * ( T -T_o) ]

=>   Q_i  = m_i [ 2.05 * 10^3 * ( 0 -(-12)) + 334 * 10^3  +  4200 * ( 75 - 0) ]

From

 Heat \ loss\ by\ ice  =  heat\ gained\ by\  water\

We have that

  m_i *  673600  =15750

=>     m_i =  \frac{15750}{673600}

=>     m_i =  0.0234 \  kg
