4,410 kJ
Explanation:
Gravitational Potential Enegry (GPE) is calculated as;
GPE = <em>m*g*h</em> where;
m = mass (kg)
g = gravity (m/s²)
h = height (meters)
= 90 * 9.8 * 5000
= 4,410,000 joules
= 4,410 kJ
For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
Answer:
2.5 Times . 10–3 L.
Explanation:
1 L = 1000 mL
1 mL = 1×10⁻³ L
2.5 mL / 1000 = 2.5×10⁻³ L
2.5 mL . 1×10⁻³ = 2.5×10⁻³ L
