Answer:
Explanation:
GIVEN
Force (F) = 8 N
Distance (d) = 2.5 metres
Work done = ?
WE know we have the formula
work done = F * d
Work done = 8 * 2.5
= 20 Joule
Hope it helps :)
The meat in the freezer is frozen.
Everything else in the freezer is frozen too.
Nothing in the refrigerator is frozen.
The freezer is colder than the refrigerator. <span>
Mildred takes a pound of frozen hamburger meat out of the freezer
and puts it into the refrigerator. The meat is colder than anything
else that's in there.
Heat flows from the air in the refrigerator into the frozen hamburger (C)
and warms up the meat. When the temperature of the meat warms up
to the temperature of the air in the refrigerator, the heat stops flowing.</span>
Answer:
For diatomic oxygen:V=539.06 m/s
For carbon dia oxide:V=459.71 m/s
For dia atomic hydrogen:V=2156.25 m/s
Explanation:
As we know that
Root mean square velocity V

Where
R is the gas constant

T is the temperature (K).
M is the molecular weight.
For diatomic oxygen:
M=32 g/mol
T=273+100 = 373 K



V=539.06 m/s
For carbon dia oxide
M=44 g/mol
T=273+100 = 373 K



V=459.71 m/s
For dia atomic hydrogen:
M= 2 g/mol
T=273+100 = 373 K



V=2156.25 m/s
Chemicals are released by the damaged tissue to bring platelets to the area to become sticky and to plug the vessels. An inflammatory response occurs which brings immune cells to fight infection and other clotting factors come to begin forming a new tissue.
