Answer:
This is the answer: The speed of a proton is about 5.0 × 10⁵ m/s
Explanation:
Because of the speeds of protons! :D
B and C are the correct answers because when you stand in an open space the ground is an conductor therefore adding and electric shock to your day
Answer:
a. x=5355m b. food
Explanation:
A wave is a disturbance wic travels through a medium, it transfers energy without the displacement of the medium itself.
the problem can be solved with this formula v
v=2x/t
v=speed of the ultrasonic wave in seawater
x=te distance between the seawater surface and the seawater bed
t=time it takes to travel to and fro te seawater bed to the surface
v= 1530 m/s, t=7 s , x=?
1530=2x/7
1530*7=2x
x=5355m
b. An example of stored h energy is food, petroleum etc.Chemical energy are Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; called exothermic.
Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds. we eat food so that we can h enough energy to carry out our day to day task.
Answer:
Explanation:
60000 kJ / h = 60000 x 1000 / (60 x 60 )
= 16667 J /s
a)
where 
and 
are heat supplied and heat given from outside source .
Here = 16667 J/s
= 15.684
16667 / W = 15.684
W= minimum power supplied = 1062.7 W.
b )
If 
=19.87
= 838.8 W .
