Pendulum Lab.. List each measurement name, a representative value [Units] ± σ with explanation. Your two measurements were Length and Period.

Expert Solution

In case of compound pendulam

required apparatus are Compound pendulum, stop watch, telescope and pointer

Formula:

The expression for acceleration due to gravity ‘g’ is given by g = 4π²(l/T²) cm/sec²

where l = equivalent length of the simple pendulum (whose time period is T) in cms.

T = Time period of oscillation

In case of Torsional pendulam

required apparatus are Torsional pendulum, Stopwatch, Vertical Pin, Balance, Weight Box, Screw gauge and Scale

Formula:

n = (8π/a⁴)×(MR²/2)×(L/T²)

Where n = rigidity modulus of the given material

a = radius of the wire

M = mass of the wire

R = radius of the wire

L = length of the given material of the wire

T = time period.

Suppose there are two countries. In the rich country, the representative consumer has Hr units of human capital, and total factor productivity is zr. In the poor country, the representative consumer has Hp units of human capital, and total factor productivity is zp. Assume that b and u are the same in both countries, Hr > Hp, and zr > zp. (a) How do the levels of per capita income, the growth rates of per capita income, and real wages...

Summarize the material covered in today’s lab. Name and describe each of the phases of the cardiac cycle. Be sure to include the events that occur during each phase. Focus on the mechanical events (contraction and relaxation) of the chambers, the pressure changes in the heart, the position of the valves, and the heart sounds. Be sure to explain what causes each of the events you describe.

In C++ In this lab we will creating two linked list classes: one that is a singly linked list, and another that is a doubly linked list ( This will be good practice for your next homework assignment where you will build your own string class using arrays and linked list ) . These LinkedList classes should both be generic classes. and should contain the following methods: Print Add - Adds element to the end of the linked list. IsEmpty...
