According to Newton's third law of motion, which of the following best describes the forces of the tennis racket and the ball?
Effectus [21]

Answer:

OA is the answer

Newton's third law of force states that: for every action (force) in nature there is an equal and opposite reaction. what this means is that if I push on you, you're also pushing me because I have slowed down but now you are falling to the mud.

if you have ever seen newtons balls then you will know what I am talking about, one is moving then it hits the other and it stops moving because now the other one is moving,

I hope this makes sense, if it doesent then go to the net and watch some videos on Newtons third law

hope it helped

Which friction-reducing technologies are used in the Variable Compression Turbo Engine?
Grace [21]

Friction-reducing technologies used in the Variable Compression Turbo Engine are Diamond-like coating on valve lifters, micro finishing on crankshaft and camshaft and mirror bore coating on cylinder wall.

<u>Explanation:</u>

Variable compression is a technology to adjust the compression of an internal combustion engine while the engine is in operation. At this time friction may occur that need to be reduced. To reduce this friction some technologies are used like

  • Diamond-like coating on valve lifters
  • Micro finishing on crankshaft and camshaft
  • Mirror bore coating on cylinder wall

A hydrogen free diamond like carbon coating is applied to an engine valve lifter to reduce mechanical loss. Micro finishing on crankshaft and camshaft achieves improvement in geometric parameters such as roundness. Mirror bore coating on cylinder wall raises energy efficiency by reducing the friction inside the engine.
