Observe that the given vector field is a gradient field:
Let 
, so that
Integrating the first equation with respect to 
, we get
Differentiating this with respect to 
gives
Now differentiating 
with respect to 
gives
Putting everything together, we find a scalar potential function whose gradient is 
,
It follows that the curl of is 0 (i.e. the zero vector).
By flooding the uterus with a rich supply of blood for the tissue that lines the inner side of the uterus and it is called the endometrium. This happens each month during the menstrual cycle, when the body with the help of hormones which have different levels in the different times of the cycle. When it is time to prepare the uterus for a fertilized egg, the blood vessels of the endometrium swell and supply more blood to the tissue.
In the case that a fertilized egg cell reaches the uterus, it will attach itself to the endometrium and this is the place where the fetus, and then the baby will start growing. The endometrium is the base for the growth of the placenta which is the main and most important factor for protection and nutrition of the baby.
Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.
1.)
Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)
Fw = m * 9.81 m/s²
560N = m · 9.81 m/s²
m ≈ 57.08 kg
2.)
d = 350 meters
t = 65 seconds
velocity = d/t
velocity = 350 meters / 65 seconds
velocity ≈ 5.38 meters/sec
3.)
Force = 35N
Distance = 2 meters
Work = Force · Distance
Work = 35N · 2 meters
Work = 70 J
Answer:
It would be A.
Explanation:
When oxygen is released, that oxygen rises and the ballons temperature will go down. Heat rises so if the ballon is dropping, then the temperature is dropping.
