How many kilowatt hours does it take to lift an apple that weighs 100g 1 meter.(use 9.8 kg
m/s2 for the force of gravity)

The answer to your question is   Power = 0.98 W  or 9.8 x 10⁻⁴ kW

Explanation:

Data

Power = ?

mass = 100 g = 0.1 kg

distance = 1 m

gravity = 9.8 m/s²

Formula

Power = Work / time

Process

1.- Calculate the Work

      Work = Force x distance

      Force = mass x gravity

      Work = mass x gravity x distance

      Work = (0.1 kg)(9,8)(1)      

      Work = 0.98 J

2.- Calculate the power

       Power = 0.98 J / 1 h

       Power = 0.98 W  or 9.8 x 10⁻⁴ kW

(1) Hospitability is our prime hallmark.

You have heard that, "Ghanaians are hospitable." Ghanaians are hospitable, at least towards foreigners. We are mostly friendly and welcoming to visitors or guests because that is a part of our cultural make-up. In fact, we are warm-hearted, neighbourly, accommodating and open-handed. Any average foreigner can attest to this attitude of ours.

(2) Ghanaians are rarely satirical.

The Ghanaian citizenry possess an atypical sense of satire in everyday life. Satire is in our blood and we sometimes play it carefully. We literally mock our wayward politicians on a daily basis, with the aim of demonising them and exposing their evil deeds.

On social media especially, we often resort to biting satire of our unjust, wicked and corrupt system. And virtually no guilty person or institution can escape our sociopolitical satire. For satire enlightens the masses in unusual ways.

(3) Ghana is the land of real peace.

Okay, Ghana is the most peaceful country in Africa and beyond. Ghanaians abhor mass bloodshed. Look! Religion may have separated us, ethnicity may have disconnected us, politics may have divided us, and wealth may have classified us; however, we still coexist with one another in peace and togetherness.

(4) We have a stable democracy.

Thank God Ghana has never experienced any civil war unlike most African countries. Though we have had several military interventions in the past after our independence; we now enjoy a stable democracy, where the people are sovereign under the rule of law in a free and open society with constitutionally guaranteed rights and freedoms.
