What is the Gravitational Potential Energy of a 30 kg box lifted 1.5 meters off the ground?

Physics
1 answer:
juin [17]3 years ago
6 0

Answer:

<h2>441 J</h2>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

PE = 30 × 9.8 × 1.5

We have the final answer as

<h3>441 J</h3>

Hope this helps you

What is the KE if a 10kg mass traveling at 5 m/s
11111nata11111 [884]

Answer: KE = 25 J

Explanation: You must use the formula

KE = 1/2 m v²

to solve this problem.

KE = 1/2 (10 Kg) (5 m/s)

KE = 1/2 (50 kgm/s)

KE = 25 J

Using evidence from the article, defend the concept that Earth’s magnetic poles have swapped places over time.
Mamont248 [21]

Answer: Scientists found evidence of Earths magnetic field reversal in rocks on the ocean floor at plate boundaries. These rocks have alternating polarity due to magnetization that occurred during their cooling period. Using radio metric dating, scientist estimate that reversals occur approximately every several hundred thousand years.

Does water expand more as the temperature drops even more below 0 deg? I am worried about the coolant in my rad. as the temp.is

Water is, indeed, an exception. Normally when temperature drops, material shrinks. Water doesn't, water expands instead.
