sp ht of H2O = 1 cal/g C

Heat = mass (sp ht) (change in temp)

Q = m (sp ht) (t2 - t1)

Q = 16 g (1 cal/g C) (46 C - 11C)

Q = 560 cal

or

Q = 560 cal (4.187 J / cal)

Q = 2345 J

The heat energy required to raise the temperature of 16g of water from 11degrees celsius to 46degrees celsius is the 0.1% of that heat required to change this world.

Q=c*m*delta(t)=(4.2*10^3)*0.016*(46-11)=2352 J

Equation is
Q1-Q2=m x s x (t1-t2)
= 16 x 1 x(35)
=560 calories.

hi...you have have been given it suitable. The 0.5 meter is a purple herring that the instructor purely positioned there to throw you off. on account that a radian is a level of perspective, it is not appropriate how long the string is...5 inches or 5 miles, one revolution is 2pi radians. For angular velocity, it particularly is comparable...you purely might desire to degree radians according to 2nd...it is not appropriate how massive the situation it particularly is spinning is. (for example, the angular velocity of the earth is one million/2 the angular velocity of the hour hand of a clock!)

mass=0.0164
specific heat of water=4190J/kg
change in temperature=(46-11)=35
heat energy,Q=m.c.t=0.016.4190.35
=2346.4J
