Answer: C
Explanation: Side post terminals need to be removed to inspect them for corrosion.
Over tightening the terminal bolt can damage side post terminals.
The battery terminals and cable ends can corrode especially when the battery or car is not used for a long period of time. Corrosion limits a battery's lifespan and so should be prevented. To inspect the areas where corrosion occur on a side-post battery, you need to remove the terminals.
Also, it is true that over tightening the terminal bolt can damage the side post terminals. The covering on the battery can become twisted, and make the seals on the terminals leak.
Answer: option 3 Ta < Tb = Tc < Td
Explanation:
Ta = mv²/r = mv²/r
Tb = m(2v)²/2r = (m)4v²/2r = 2mv²/r
Tc = (2m)v²/r = 2mv²/r
Td = (2m)(2v)²/r = (2m)4v²/r = 8mv²/r
You mean like a box sitting on a table.
One force is the force of gravity, pulling downward on the box.
Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.
The other force is the force of the table pushing upward on the box. It's called
the "normal force".
A heat engine is operating between 287 c and 32 c. if the engine extracted 400 mj of energy from fuel, 4109.6 Jews mj of energy could be used as mechanical energy
Using the temperatures, a heat engine's efficiency is determined (lowest and highest).
The ratio of the system's provided heat to the desired work is considered the system efficiency. An engine's efficiency ranges from 0 to 1.
The efficiency of the engine is 27%, or 0.27. Since the heat was turned down due to the 3000 gems, we must find productive employment. Heat input and network efficiency are connected. That is the line. Qc was rejected by two W plus heat, leading to Qh. The cost of networking is composed of Nita W and Nita Qc. The network completed is identical to Nita. Q C is split into two halves. As a result, we must divide our efficiency, which is 0.27, by 3000. The engine's work is represented by this. Let's calculate the result of 0.27 multiplied by 3000 divided by 1. 1109 and 0.6 gems are the answer. He rejected our quote, which is +110 9.6 plus three thousand. 4109.6 Jews is quite close to the heat input.

Answer
Given,
Periscope uses 45-45-90 prisms with total internal reflection adjacent to 45°.
refractive index of water, n_a = 1.33
refractive index of glass, n_g = 1.52
When the light enters the water, water will act as a lens and when we see the object from the periscope the object shown is farther than the usual distance.
