Answer:
D. 214 kPa
Explanation:
The absolute pressure is given by:
where
p is the absolute pressure
is the atmospheric pressure
is the gauge pressure
In this problem, we have
So, the atmospheric pressure is
Answer:
0.00000131569788654 C
0
Explanation:
R = Radius = 7.1 cm
L = Length of shell = 251 cm
r = 25.2 cm
E = Electric field = 37400 N/C
Electric field is given by
The net charge on the shell is 0.00000131569788654 C
Here, 4.07<7.1 cm which means r'<R
From Gauss law the electric at that point is 0
Answer:
NASA sees direct proof for the hole in the ozone layer getting smaller .
Explanation:
According to an research in the year 2017 ' NASA confirmed that size of the ozone hole n September was smaller as it was in earlier three decades ago . They found that chlorine from chlorofluorocarbons (CFC) are reducing which results in the depletion of hole in the ozone layer.
Ozone layer plays an very important role in protecting life on earth from very dangerous rays which cause many deadly diseases and many other problems. Since the world banding the substances which cause ozone depletion , scientists are thinking that by the year of 2070 the hole can recover its size level that it was in year of 1980.
