An unruly demonstrator lifts a stone of mass 200 g from the ground and throws it at his opponent. At the time of projection, the stone is 150 cm above the ground and has a speed of 3 m/s. Calculate the work done by the demonstrator during the process. If it takes one second for the demonstrator to lift the stone and throw it, what horsepower does he use?

The magnetic force on a charged particle is always perpendicular to its velocity. Therefore, the work done by the magnetic force on the charged particle is zero. Here, the kinetic energy and speed of the particle remain unaffected, while the velocity changes due to the change in direction of its motion.

(d) it moves in a circular path.

When the force on a particle is always perpendicular to its velocity, the work done by the force on the particle is zero, as the angle between the force and velocity is 90. So, kinetic energy of the particle will remain constant. The force acting perpendicular to the velocity of the particle provides centripetal acceleration that causes the particle to move in a circular path.

(a) the path taken by the suitcase

(b) the time taken by you in doing so

(d) your weight

Work done by us on the suitcase is equal to the change in potential energy of the suitcase.

i.e., W = mgh

Here, mg is the weight of the suitcase and h is height of the table.

Hence, work done by the conservative (gravitational) force does not depend on the path.

Numerous hardware accelerators have been proposed to meet the performance and energy-efficiency requirements of AI applications. But these accelerators have been developed in separate silos with little to no infrastructure for integrating these accelerators in the top-level system stack. We present AI-RISC as a solution to bridge this research gap. AI-RISC is a hardware/software codesign methodology where AI accelerators are integrated in the RISC-V processor pipeline at a fine-granularity and treated as regular functional units during the execution of instructions. AI-RISC also extends the RISC-V ISA with custom instructions which directly target these AI functional units (AFU) resulting in a tight integration of AI accelerators with the processor. AI-RISC adopts a 2-step compilation strategy where open-source TVM is used as the front-end compiler while LLVM based custom C-compiler is used as the backend along with complete SDK generation. AI-RISC enables a RISC-V based processor which supports both AI and non-AI workloads for edge applications, flexibly hot-swaps AFUs when better hardware is available and scales with new instructions as AI algorithms evolve in the future.

Loyle Campbell is a research fellow at the German Council of Foreign Relations Center for Climate and Foreign Policy focusing on energy and resource policy. Before joining this centre, Loyle completed fellowships with the Wilson Center and on the United States House Select Committee on the Climate Crisis and published work assessing how China, Europe, and the United States compete for leadership over the global energy transition. Before studying, Loyle worked in various positions throughout the Canadian oilfield from 2011 to 2017. He left the industry due to workplace injury. He applies his experience in this sector to advocate for an inclusive and just energy transition. Loyle has a MA in international energy from Sciences Po Paris School of International Affairs and a BSc in political science from the Vrije Universiteit Brussel in Belgium.

LOHUM is a leading organization in the field of battery recycling and second-life solutions for lithium-ion batteries (LIBS). The company is among very few Indian LIB lifecycle management firms currently refining the black mass locally to recover valuable battery raw material. Rajat Verma, the Founder & CEO of LOHUM, is spearheading their efforts. In this exclusive interview with a reporter, he shares their work, scale, and vision for LIB lifecycle management.

The MG India and LOHUM partnership, which began in June 2023, aims to develop the concept of second-life solutions for batteries, ensuring their efficient utilization and contributing to a closed-loop energy economy. The project will harness the potential of used EV batteries by repurposing them as Battery Energy Storage Products (BESS), effectively extending their life cycle and optimizing resource usage. The initial offering under this partnership will be a 100% Off-Grid, 5kWh Battery Energy Storage System (BESS) to meet the essential energy needs of urban and rural India by solving the end-of-life EV battery problem and organizing the battery waste sector. The BESS will provide uninterrupted power supply even in regions with unreliable grid infrastructure.

Sol. The situation is shown in figure (8.9). Take A + B as the system. The only external force acting on the system is that needed to hold A fixed.(You can imagine the experiment being conducted in a gravity free region or the particle may be kept and allowed to move on a smooth horizontal surface, so that the normal force balances the force of gravity). This force does no work on the system because it acts on the charge A which does not move. Thus , the external forces do no work and internal forces; are conservative, the total mechanical energy must, therefore, remain constant . there are two internal forces ; FAB acting on A and FBA acting on B. The force FAB does no work because it acts on A which does not move. The work done by FBA as the particle B is taken away is ,
