Escribe how you will determine the amount of energy added to the liquid during heating. Hint: Energy is added to the liquid by the immersion heater the metal coil placed in the liquid after the thermometer reading stabilizes. The Immersion heater delivers energy to the liquid at a rate of 21.1 watts, or 21.1 joules/s. Notice that there is a stopwatch available when you click the tool icon in the upper right. BIU Score: 0/5 3. Select a trial from the set of videos above. Make measurements you need and use them to calculate the specific heat. Show your process and results below. BIU Score: 0/5 4. 2.a. The table below shows the specific heat of six different liquids. I have mass of cup= 29.1g
mass of liquid= 510.2g
initial T= 21.64 C
final T= 36.49 C
time=916.2 seconds
how can i find specific heat. do I add masses or subtract them? I need to fund unknown substance.

your answer would be fusion

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

it's a b and
