Answer:
False
Explanation:
The ground or surface cannot give off energy
(correct me if i am worng) :)
The answer is 117.6 J
The potential energy of
the object is actually its stored energy:
<span>E =
m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.
m = 4 kg
g = 9.8 m/s</span>²
h = 3 m
E = 4 * 9.8 * 3 = 117.6 J
1 Nautical metre=1852 metres
10×1852
=18520 metres
Answer:
they store information
Explanation:
Information are encoded on the magnetic part of a hard drive and the strip of a credit card.
- On the drive, series of magnetic fields are used to encode information.
- The data is stored in form of zeros and ones.
- A credit card has a magnetic strip where information is encoded.
- The stripe provides a readability function for electronic devices.
Extinction of a species is most likely to occur as a result of "<span>environmental changes"
