Well, before we discuss that, I think we have to carefully understand
and agree on something. We have to be very clear about what we
mean by 'weight' ... is it what you feel, or is it the product of
(your mass) x (the acceleration of gravity where you are).
If you're on a space ship, then any time your engine is not burning,
you feel weightless. It doesn't matter where you are, or what body
you may be near. If you're not doing a burn, and the only force on
you is the force of gravity, then you don't feel any weight at all.
But of we say that your 'weight' is the product of
(your mass) times (the acceleration of gravity where you are),
then it depends on where you are, and whether you're close to
the Earth or closer to the moon. You may not feel it, but you're
going to have weight, and it's going to change during your trip
in space.
You know that the force of gravity depends on how far you are
from the body that's attracting you.
-- As you travel from the Earth to the moon, gravity will pull you
less and less toward Earth, and more and more toward the moon.
-- Your weight will get less and less, until you reach the point
in space where the gravitational attractions are equal in both
directions. That's about 24,000 miles before you reach the
moon ... about 90% of the way there. At that point, your weight
is really zero, because the pull toward the Earth and the pull toward
the moon are equal.
-- From there, the rest of the way to the moon, your weight will
start to grow again. It begins at zero at the 'magic point', and it
grows and grows until you reach the moon's surface. When
you're there, your weight has grown to about 1/6 of what you
weigh on Earth, and it won't get any bigger. If you weigh
120 pounds on Earth, then you weigh about 19.86 pounds on
the moon ... PLUS your space suit, boots, heater/air conditioner,
oxygen tank, radiation shielding, radio, and all the other stuff that
you need to survive on the moon for a few hours.
Answer:
1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2
2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose
the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52
now if you use 10 as the gravity= 2.4*10= 24
3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51
250/10= 25( if gravity is 10)
Explanation:
The given data is as follows.
Temperature of metal = 
= (296 + 273) K
= 569 K
Density of the metal = 8.85 
= 
(as 
)
Atomic mass = 51.40 g/mol
Vacancies = 
Formula to calculate the number of atomic sites is as follows.
n = 
= 
= 
Now, we will calculate the energy as follows.
E = 
where, K = 
E = 
= 
Therefore, we can conclude that energy (in eV/atom) for vacancy formation in given metal, M, is .
The National
Fire Protection Association (NFPA) states that the furthest reaches of human
temperature viability is 212°F, well beneath temperatures found in most
noteworthy structure fires that are past the development (early) stage. In the
present fire conditions, temperatures higher than 500°F can be effortlessly gotten
inside three to four minutes. Flashover, which happens at roughly 1,100°F, can
grow well under five minutes.2 If a space isn't legitimate for firefighters,
caught casualties aren't probably going to survive either. Set aside the
opportunity to make it safe and keep your firefighters from going for broke.
<span>60% of the
casualties were found to have been presented to warm (most at temperatures over
200°F; some were beneath) and mugginess for six to seven minutes (remote from
the fire range).</span>
