Answer:
Mechanical efficiency: the comparison of the machine's work output with it's work input
Mechanical advantage: the number of times that the machine multiplies the force
Explained:
Answer:
Shift it to the left toward the reactants.
Explanation:
Le Chatelier's principle states that if a chemical system is in equilibrium and one of the factors involved in the equilibrium is altered (e.g temperature,pressure or concentration) ,the equilibrium will shift, so as to neutralize the effect of the change.
If a chemical system is in equilibrium, in which the reaction is exothermic and the temperature is being increased, the equilibrium will shift to left, favoring the backward reaction (reactants) as the constant K decreases.
Answer:
When you play basketball, you play on a surface called a Court with 2 symmetrical halves, both consisting of a basket or net on each end. The aim of the game is to score the most points or baskets in the allotted time. Rules vary from league to league but in the NBA games last for 48 minutes with four quarters of 12 minutes. In a basic basketball game, the time limit can be changed or it can be a game of the first to a certain number of baskets.
Teams
You can play in teams which can consist of 1 to 5 players however you can also play on your own as well when practising or executing Drills. Playing with friends can be useful to help share advise and have more opportunities to learn and easily begin to understand basic basketball rules through playing regularly.
Positions
Each player has his or her own position name on the court and this is usually determined by height, speed and agility. The tallest players are usually allocated Centre position, and they are usually available to rebound both defensively and offensively as well as being the best player for tip off. These players in the NBA can range from 6ft,7 to 7ft+ The next tallest players are usually Forwards and the fastest of these are called Power forwards. The smallest players are called Guards who are usually the quickest, both physically and mentally and who co-ordinate all the plays laid down by the coach of the team.
Basic Rules
When moving the basketball around the court, the players must travel around using a technique called Dribbling. To dribble the player must not take more than a step and a half without the ball coming into contact with the court and back to the players’ hand again in a bouncing motion. If more than 1 and a half steps are taken this is a Travelling violation. Once the player has stopped dribbling they may not move again until the ball comes to them from another player. Each shot taken can be done either inside or outside the shooting Area. Outside the shooting area a successful shot is worth 3 points and inside the area is worth 2 points. However inside the shooting area, there is an area named The key in which players may not remain for More than 3 seconds to prevent goal hanging. Additional single points can be scored from the free throw line in a penalty.
These are all basic basketball rules and there are many others that need to be obeyed in order not to violate the rulebook but as a beginner are not necessary to learn until you have mastered the basics.

Hope this helped u! Have a great day and please mark me brainliest
Answer:
Part a)
Part b)
Explanation:
Mass of the disc is given as
m = 2.00 kg
radius of the disc is given as
r = 7 cm
so moment of inertia of the disc is given as
Now given that torque on the disc is
so here the angular acceleration is given as
Part a)
if disc start from rest and then achieve final speed as 1200 rpm then
so final speed is
now the time taken to reach this speed is given as
Part b)
Number of revolution in the same time is given as
No because sugar is made up of organic material
