what is the difference in gravitation potential energy when a 3.5 of box is raised from a height of 1.2m to a height of 4.0m?

mario62 [17]

Answer: 96.138 J

Explanation:

Use equation for potential gravitational energy : Ep=mGh

Ep1=mGh1

Ep2=mGh2

-------------

Ep1= 3.5*9.81*1.2

Ep1=41.202 J

Ep2=3.5*9.81*4

Ep2=137.34 J

Ep=Ep2-Ep1

Ep=137.34-41.202

Ep= 96.138 J

A student is studying the potential energy change of a 50 kg object raised 110 km above Earth's surface. What will be the percen

Law Incorporation [45]

Answer:

The percentage error is given by 99.9 %

Explanation:

Given:

Mass of object $m = 50$ kg

Height $h = 110$ km

From the formula of potential energy,

$U = mgh$

Where $g = 9.8 \frac{m}{s}$

$U = 50\times 9.8 \times 110000$

Here true value of potential energy,

$U = 50 \times 9.8 \times 11 \times 10^{4}$

Approximate value of student,

$U = 50 \times 9.8 \times 110$

Absolute error is given by

= true value - approximate value

= $50 \times 9.8 \times 11 \times 10^{4} - 50 \times 9.8 \times 110$

= $53846100$

Hence percentage error,

$= \frac{53846100}{50 \times 9.8 \times 11 \times 10^{4} }$

$= 0.999 \times 100$ %

$= 99.9$ %

Therefore, the percentage error is given by 99.9 %
