Answer 1

Explicação:

Customer service can have a big impact on your bottom line.

It’s often said that it’s cheaper to keep existing customers than to find new ones. (It’s even been estimated that acquiring customers costs 6–7x more.) And it’s true: Bad customer service is a key driver of churn. The U.S. Small Business Administration reports that 68% of customers leave because they’re upset with the treatment they've received. Don’t let that happen to you. Prioritizing customer service support helps you attract and retain loyal customers, and can have a big impact on your company’s bottom line.

Answer 2

Olá!

A fórmula de força é:

F = m . a

Sendo assim, podemos substituir os valores dados no enunciado:

F = 30 . 2

F = 60N
