Answer:
Some effects include:
- Alumminum particles reach aquatic environments and can harm fish and other wildlife. In these ecosystems acidity can also prevent fish eggs from hatching.
-
Acid rain can remove important minerals and nutrients from the soil preventing trees to grow, it can also poison them due to the aluminum particles.
- The fenomenon of e
pisodic acidification can occur, this means that acidity can be present in m
elting snow generating small lapses of higher acidity
- It can occur a n
itrogen pollution

Explanation:
Formula to determine the critical crack is as follows.
= 1, = 24.1
[/tex]\sigma_{y}[/tex] = 570
and,
= 427.5
Hence, we will calculate the critical crack length as follows.
a =
=
=
Therefore, largest size is as follows.
Largest size = 2a
=
=
Thus, we can conclude that the critical crack length for a through crack contained within the given plate is .
Answer:
3.93 m/s
Explanation:
= Mass of Ashley = 56 kg
= Mass of Miranda = 64 kg
= Initial Velocity of Ashley = 2.6 m/s
= Initial Velocity of Miranda = 5.1 m/s
v = Velocity of combined mass
As linear momentum is conserved
The speed at which they both slide down together is 3.93 m/s
Answer:
same
Explanation:
Acc. to Einstien's postulate of special theory of
Relativity ,
Velocity of the light beam is same in all frames of references
(a) If the freight car is at rest
The frame we can assumed as Non - inertial frame of reference
s
In the inertial frame of reference , velocity of the light beam has its own value as : 3 x 10^8 m/s
(b) If the freight car is moving , the frame we can assumed as Non -inertial frame of reference
In thus case also , The velocity of the light beam will also have the same value as ; 3 x 108 m/s
