Minakshee wants to displace a wooden block from point A to point B along the surface of a table as shown. She has used force F for the purpose.
Which forces have been overcome using that energy?

Minakshee wants to displace a wooden block from point A to point B along the surface of a table as shown. She has used force F for the purpose. Has all the energy she spent been used to produce acceleration in the block?

Choose the correct options The rough surface of a horizontal table offers a definite maximum opposing force to initiate the notion of a block along the table, which is the motion of a block along the table, which is proportional to the resultant normal force given by the table. Forces F_1 and F_2 act at the same angle theta with the horizontal and both are just initiating the slide motion of the block along the table. Force F_1 is a pulling force while the force F_2 is a pushing force. F_2>F_1 , because

The figure shows the elliptical orbit of a planet about the sun S. An ellipse is the curve obtained when a cone is cut by an inclined plane. It has two focal points. The sum of the distances to the two focal points from every point on the curve is constant. F_1 " and " F_2 are the two focal points of the ellipse . The shaded area CF_1D is twice the shaded area AF_1B. t_1 is the time taken by the planet to move from C to D and t_2 is the time to move from A to B Which laws do we understand from the above diagram and description?

A force vec((F)) = - K(yhat(i) + x hat(j)) (where K is a positive constant) acts on a particle moving in the X-Y plane. Starting from the origin, the particle is taken along the positive X-axis to the point (a, 0) and then parallel to the Y-axis to the point (a,a). The total work done by the force vec(F) . of the particle is

Use your brain power: If a car, starting from point P, goes to point Q and then returns to point P (see Figure), how much distance has it travelled and what is its displacement?

A particle moves from a point (-2hat(i) + 5hat(j)) " to" " " (4hat(j) + 3hat(k)) when a force of (4hat(i)+ 3hat(j)) N How much work has been done by this force?

Paragraph based Questions : Read the paragraph and answer the questions given below : Remediation is the process of removing dangerous or poisonous substances from the environment, or limiting the effect that they have on it. When any biological organism is used for remediation, it is called bioremediation. When plant species are used for the purpose of remediation, it is called phytoremediation. When any microbes are used then it is named as microbial remediation. The methods of such remediation have helped to clean the environment from toxic effluents, especially sewage and crude oi]. Dr. Anand Chakraborty, a scientist of Indian origin, has worked on Pseudomonas aeruginosa which have reduced the crude oil films into carbon dioxide and water. Which environmental pollutant is mainly removed through bioremediation processes?
