The power expended when a 10 N barbell is raised 2. 0 m in 2s is

Answers

Answer 1
Answer:
Work done = (force) x (distance)
                   = (10 N)  x  (2  m)         =     20 joules . 
                    
 Power = (work done) / (time to do the work)
             =          (20 J)  /  (2 sec)
             =            10 joules/sec        =      10 watts .

When two gears are mashed, the revolutions per minute (rpm) are inversely proportional to the number of gears

Answers

Not exactly.  The RPM is inversely proportional
to the number of teeth on the gears.

Note that in order for them to stay meshed, that'salso going to work out
to be the ratio of their radii.  Otherwise they won't stay engaged.

What is the taste of the resulting mixture?

Answers

The taste of the resulting mixture depends on the constituents of the mixture. The amount of the constituents of the mixture also plays a vital role in determining the taste of the mixture.

Further Explanation:

The mixture is a composition of two or more different types of compounds or entities mixed in a desired ratio in order to obtain a different product as a result of the two quantities. The mixing of two or more entities is called as a mixture only when there is no chemical reaction taking place between the two entities.

The taste of a mixture depends on the quantity of the compounds mixed in the formation of the mixture. If we consider the example of the mixture of glucose and water, the sweetness of the mixture depends on the amount of glucose added to the water. The more the amount of glucose, more will be the sweetness of the solution.

In the same manner, in the solution of salt and water, the taste of the mixture depends on the amount of salt added to the water.  

Therefore, it can be stated that the taste of the mixture is dependent on the amount of the compound used in the formation of the mixture.

The taste of the resulting mixture depends upon the ingredients and constituents.

The particular ingredients being blended will determine the flavor of the finished product. When combined, different components can have contrasting flavors and produce a distinctive flavor profile.

Sweet: A mixture that contains sugar, honey, or other sweet substances is likely to taste sweet.

Salty: Adding salt, soy sauce, or salty seasonings will make a dish taste salty.

Sour: When sour flavors, such as vinegar or lemon juice, are combined with other substances, the result is a sour flavor.

Spicy: When combining hot or spicy ingredients, such as chili peppers or hot sauces, the mixture will taste hot or spicy.

Bitter: When combined with other ingredients, some items, such as bitter melon or greens like kale, can add to the bitterness of the dish.

Hence, the taste of the resulting mixture depends upon the ingredients.
