Can you explain the answer of this question below:An astronomer has to...
**Given information:**
- Total weight of the astronomer = 80 kg
- Change in gravitational potential energy = 1000 J
- Height climbed by the astronomer = 10 m
**Formula:**
Gravitational potential energy (PE) = mass (m) x gravitational acceleration (g) x height (h)
**Explanation:**
The gravitational potential energy gained by the astronomer while climbing up the ladder can be calculated using the given formula. Since the initial position is on the moon's surface and the final position is 10 m above the surface, the change in height is 10 m.
Given that the change in gravitational potential energy is 1000 J, the equation can be rewritten as:
1000 J = 80 kg x g x 10 m
Simplifying the equation:
1000 J = 800 kg·m²/s² x g
Dividing both sides by 800 kg·m²/s²:
1.25 J/kg = g
The unit for gravitational acceleration is meters per second squared (m/s²), so the value of g on the moon is 1.25 N/kg.
Therefore, the correct answer is option D: 1.25 N/kg.
- Total weight of the astronomer = 80 kg
- Change in gravitational potential energy = 1000 J
- Height climbed by the astronomer = 10 m
**Formula:**
Gravitational potential energy (PE) = mass (m) x gravitational acceleration (g) x height (h)
**Explanation:**
The gravitational potential energy gained by the astronomer while climbing up the ladder can be calculated using the given formula. Since the initial position is on the moon's surface and the final position is 10 m above the surface, the change in height is 10 m.
Given that the change in gravitational potential energy is 1000 J, the equation can be rewritten as:
1000 J = 80 kg x g x 10 m
Simplifying the equation:
1000 J = 800 kg·m²/s² x g
Dividing both sides by 800 kg·m²/s²:
1.25 J/kg = g
The unit for gravitational acceleration is meters per second squared (m/s²), so the value of g on the moon is 1.25 N/kg.
Therefore, the correct answer is option D: 1.25 N/kg.

Can you explain the answer of this question below:An astronomer has to...
Mgh = 80 x 10 x g = 1000
g= 1000 / 800
g = 125 N/ Kg
g= 1000 / 800
g = 125 N/ Kg
