The outward push of the core created by nuclear fusion and the inward pull of gravity from the core
Answer:
the correct answer will be 6.82 %that is 7%
p(1.27)-q(0.83) =x=0.44
0.02+0.01 =0.03 (maximum uncertainty)
percentage uncertainty =0.03/0.44×100 %
=6.82%
=7%
Explanation: it was d on my end
Answer:
NO
Explanation:
if it has no acceleration then it's not moving
in ideal gas we have few things that we need to follow as following
1. Force of interaction between gas molecules are negligible.
2. There is no effect of gravity on them
3. All collisions are perfectly elastic collision.
4. there will be no energy loss
5. All newton's law are valid for them.
6. all molecules moves with same speed in random direction.
So here in order to follow all above conditions we have to maintain low pressure and high temperature in the gas due to which the density of gas becomes low.
So correct answer will be
<em>The gas density is low and the temperature is high.</em>
Answer: 1.124 m
Explanation:
This situation is a good example of the projectile motion or parabolic motion, and the main equations that will be helpful in this situations are:
x-component:
(1)
Where:
is the initial speed
is the angle at which the venom was shot
is the time since the venom is shot until it hits the ground
y-component:
(2)
Where:
is the initial height of the venom
is the final height of the venom (when it finally hits the ground)
is the acceleration due gravity
Knowing this, let's begin:
First we have to find from (2):
(3)
Rearranging (3):
(4)
This is a <u>quadratic equation</u> (also called equation of the second degree) of the form 
, which can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving (6) we find the positive result is:
(7)
Substituting (7) in (1):
(8)
Finally:
(9)
