Answer:

The relation between frequency and time period is given by:

f = 1/T

Explanation:

In a wave motion, the particle move about the mean position with the passage of time. The particles rise to reach the highest point which is crest, and similarly falls to reach the lowest point which is trough. The cycle keeps on repeating.

The time period of the wave can be defined as the time taken to complete one such cycle. Time period is given by:

T = 2π/ω

Frequency can be defined as the number of cycles completed in unit time, which can be taken as the inverse of time period. frequency is given by

f = ω/2π

f = 1/T

what is the specific heat capacity of silver metal if 55.00g of the absored 47.3 calories of heat and temperature rise 15.°c

igor_vitrenko [27]

Answer:

$0.240 J/(g^{\circ}C)$

Explanation:

When an amount of energy Q is supplied to a sample of substance of mass m, the temperature of the substance increases by $\Delta T$ according to the equation

$Q=mC_s \Delta T$

where

$C_s$ is the specific heat capacity of the substance

In this problem, we have:

m = 55.0 g is the mass of the sample of silver

$Q = 47.3 \cdot 4.184 = 197.9 J$ is the amount of energy supplied to the sample

$\Delta T = 15^{\circ}C$ is the change in temperature of the sample

Solving the equation for $C_s$ , we find the specific heat capacity of silver:

$C_s = \frac{Q}{m \Delta T}=\frac{197.9}{(55.0)(15)}=0.240 J/(g^{\circ}C)$
