Answer:
0
-723.163841808 Wb
-350.282485876 Wb
Explanation:
= Permittivity of free space =
when r = 0.625 m the charges lie outside the sphere so q = 0
From Gauss law
The electric flux is 0
when r = 1.4
will be inside the sphere
The electric flux is -723.163841808 Wb
when r = 2.9 both charges lie inside the sphere
The electric flux is -350.282485876 Wb
<h2>First stage of sleep Deprivation Subject </h2>
During the first stage of sleep deprivation, the subject is NREM which stands for non-rapid eye movement. In this condition, we are not sleeping in the depth. It can be said as dreamless sleep. On electro-encephalography recording, the brain waves are not fast so they have high voltage.
In this condition, the breathing, heart rate and blood pressure is low. The sleep is comparatively tranquil. NREM lasts for 90 minutes to 120 minutes. It accounts for about 75% of the normal sleep time. Rapid eye movements do not occur.
Answer:
Explanation:
Let mass of ice required is m kg
Heat gained by ice to attain zero degree
= m x 14.1 x 2100
= 29610m J
Heat gained by ice to melt = m x 3.34 x 10⁵ J
= 334000m J
Heat gained by water at zero degree to warm up to 27 degree
m x 4190 x 27 =113130 J
Total heat gained = 476740m J
Heat lost by hot water to cool up to 27 degree
.24 x 4190 x ( 75.8 - 27 )
= 49073.28 J
Heat lost = heat gained
476740 m = 49073.28
m = 49073.28/476740 kg
=102.93 gm
