Answer 1

Explanation:

So here iy your answer

Hope it helps you

Answer 2

Provided that:

• Mass = 6 kg
• Height = 12 km
• g = 10 m/s²

To calculate:

• Potential energy

Solution:

• Potential energy = 7,20,000 J

Knowledge required:

• SI unit of potential energy = J
• SI unit of g = m/s²
• SI unit of mass = kg
• SI unit of height = m

Using concepts:

• Potential energy formula
• Formula to convert km-m

Using formulas:

• Potential energy formula is mentioned below:

• P.E = mgh

• Formula to convert km-m is mentioned below:

• 1 km = 1000 m

Required solution:

~ Firstly let us convert kilometre into metres by using suitable formula!

➝ 1 km = 1000 m

➝ 12 km = 12 × 1000 m

➝ 12 km = 12000 m

• Henceforth, converted!

~ Now let us find out the potential energy by using suitable formula!

➝ Potential energy = mgh

➝ P.E = mgh

➝ P.E = 6 × 10 × 12,000

➝ P.E = 6 × 1,20,000

➝ P.E = 7,20,000 J

➝ Potential energy = 7,20,000 J $\:$
