Answer:
Orange juice has a lower viscosity than chocolate syrup.
Explanation:
Viscosity is the measure we use to determine essentially how thick a fluid is. So, a liquid that has a high viscosity, is thicker than a liquid that has a lower viscosity. Viscosity is also benchmarked against that of water since water is considered to he the least viscous fluid. Therefore, the more "watery" the substance, the less viscous it is.
Its easy to imagine how orange juice would have a lower viscosity. When we imagine, we think about how quickly both orange juice and chocolate syrup would flow if they both were to be spilled. Basically, we would be looking at their "flow rate" where orange juice would wash away quickly while chocolate syrup would tend to stick to the surface and be slower. But lets also look why this happens. This happens because of the size of the particles. Orange juice is diluted and has a lot of water molecules which are small and can move very quickly. Chocolate syrup on the other hand is comprised of molecules that are larger and heavier and therefore take a longer time to move. So a liquid with lower viscosity is "less resistant to flow".
The goods and the services make up the basis of every economy. The goods can simply be defined as merchandise or possessions. The services can be defined as the actions through which help is provided, or work is done for someone else. Example of goods are the food and furniture, with the food being crucial for the survival of the people, while the furniture is an essential part of every home and its practicality and decor. Examples of services are teaching and car repairing. The teaching is crucial for the development of the societies, as through it the people get education, while the repairing of cars is very important as lot of people have them, can not afford to buy new ones all the time, and they need for their daily movement over longer distances.

Answer:
P = 200 [kW]
Explanation:
To solve this problem we must first find the acceleration developed, by means of the following kinematic equation.
where:
vf = final velocity = 20 [m/s]
vo = initial velocity = 0
t = time = 3 [s]
Through newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration.
F = m*a
F = 1500*6.66
F = 10000[N]
The power can be calculated by multiplying the speed by the force.
P = F * v
P = 10000*20
P = 200000 [W] = 200 [kW]
