O Tribunal de Contas é o órgão supremo de fiscalização da legalidade das despesas públicas em Portugal, conforme expressamente consagrado no artigo 214.º da Constituição da República Portuguesa (CRP). Trata-se de um órgão independente e de natureza jurisdicional, cujas competências visam garantir o rigor, a legalidade, a eficiência e a responsabilidade na gestão financeira dos recursos públicos. A sua função central é assegurar que o dinheiro público seja utilizado de forma lícita,
WAP (Wireless Application Protocol) is a set of protocols designed for wireless devices (like mobile phones and PDAs) to access internet services. It uses a client-server model, with the mobile device acting as the client and a WAP gateway/web server as the server. WAP optimizes content for low bandwidth, small screens, and limited processing power.
WAP Model Layers: (Make also diagram)
Application Layer: Includes Wireless Application Environment (WAE), mobile device specs, and content languages
1. Functions of the Family
The family plays a vital role in both individual development and social organization. These functions are broadly classified into the following categories:
A.. Socialization Function
Families are the first agents of socialization. Children learn values, customs, traditions, manners, and cultural practices from their family. Through interaction with parents and siblings, children develop language, identity, and social skil
.c. Emotional Function
The family provides love,...
Pricing policy refers to the approach or strategy a company uses to price its products or services. It plays a critical role in determining a firm's market position, profitability, competitiveness, and customer perception.
Marketers adopt different pricing practices based on the product type, market conditions, consumer behavior, and business objectives.
What are the features of Business?
Ans
The key features of a business generally include the following:
1.Economic Activity: Business is primarily an economic activity involving the production and distribution of goods and services to satisfy human needs and earn profits.
2.Profit Motive: One of the main goals of a business is to earn profits. Profit acts as a reward for the risk and effort involved.
3.Risk and Uncertainty: Every business involves some degree of risk and uncertainty due to changing
Q-2)Explain Common Bus System in detail with diagram.
The common bus system is an architecture where a single bus is used for communication
between the various components of a computer like memory, registers, and the ALU.
This system minimizes the number
of pathways
required, thereby simplifying the design and saving space.
Components:
* Set of Registers (R1, R2, ...)
* ALU
* Control Unit
* Common Bus
* Memory Unit
Operation:
* Only one register can place its contents on the bus at a time....
Q1. What are different classification of robot.
A1.Classifications of Robots:
Q2. Derive forward kinematic equation
Devices attached to the robot’s wrist that interact with the environment.
Examples: grippers, welding torches, suction cups.
Function: Convert linear motion into rotary motion.
Working Principle: Uses a lead screw mechanism; when a screw rotates, the nut moves linearly, which in turn rotates the actuator.
Applications: Robotic arms, CNC machinery, automation setups.
Pros: Precise control, high torque.
Cons: Slower speeds, wear
Two masses m1 and m2 move in a uniform gravitational field g and interact via a potential energy U(r).
(a) Show that the Lagrangian can be decomposed as
L = L_cm + L_rel
(b) Write down the Lagrange equations for the CM coordinates X, Y, Z and describe the motion of the CM. Then write the Lagrange equations for the relative coordinates and show that the motion of r is the same as that of a particle of reduced mass μ, position r, and potential energy U(r).
