Answer:

The answer is Linear Speed and centrifugal force.

Explanation:

The reason the coin in the center stays still compared to if it was on the edge is the diference in linear speed that depends on the rotational center distance.

In other words, the coin closer to the center is submitted to a low centrifugal force because it's spinning slower than the edge, and the coin closer to the edge is submitted  to a higher centrifugal force because its spinning faster than the center.

notka56 [123]
Both Miriam and Luz have a total of 36 items in their bags (4bags x 5toys +4bags x 4snacks = 20+16=36).  Since Luz has 18 toys in three bags (3bags x 6toys) that leaves 18 healthy snacks (36-18=18) for Luz to place equally into 3 bags.  So Luz has 6 health snacks in each bag (18/3=6).

madam [21]

Answer:

Hortatory.

Explanation:

When driving down the highway and one sees or reads a sign that states, "Save the planet—don’t litter." The technique of policy enactment being used is hortatory.

A hortatory technique is focused on encouraging, exhorting and urging people to do that which is right, acceptable and worthy of emulation by others.

In this scenario, commuters and road users are being urged not to litter the highway with thrash, waste, or dirt, in order to protect the planet from environmental degradation and pollution. This would help in conserving and mitigating risks posing as a threat to our dear planet and habitat.

Hence, a hortatory technique in policy implementation and enactment is primarily aimed at appealing to the sense and conscience of individuals, to engage in socially responsible acts.
