Answer:

Parallel

Explanation:

The work done is defined as the force applied on an object and the displacement in the position of the object in the direction of force.

W = F s cos A

where, F is the force, s is the displacement and A is the angle between force and displacement.

When the angle between the force and the displacement is 90 degree, the work done is zero.

To get the maximum work the angle between the force and the displacement is 0 degree.

So, to get the work done by the force the angle between the force and displacement is 0 degree that means the force and displacement is parallel to each other.

What is the total amount of heat needed to change 31g of silver at 0.0°C to 1°C? The specific heat of silver is 0.129 J/g∙°C

galben [10]

Explanation

o solve this , we need to use the formula:

$\begin{gathered} Q=m*c*(T_f-T_0) \\ where \\ m\text{ is the mass measured in kg} \\ c\text{ is the specific heat of silver=0.129 J/\degree C} \\ T_f\text{ and T}_o\text{ are the final and initial temperatures} \end{gathered}$

Step 1

) Let

$mass=31\text{ gr}$

so, we need to convert from grams to kilograms ,to do that, divide the amount in grams by 1000

$mass_{kg}=\frac{31}{1000}=0.031\text{ kg}$

and

$\begin{gathered} T_f=\text{1\degree C} \\ T_0=0°\text{ C} \end{gathered}$

b) now, replace in the formula

$\begin{gathered} Q=mc(T_{f}-T_{0}) \\ Q=0.031gr*0.129\frac{J}{g°C}(1°C-0°C) \\ Q=0.003999\text{ Joules} \end{gathered}$

so, the answer is 0.003999 Joules
