Answer: It eventually loses its stamina, and would come to a stop.
Explanation:
Answer:
The actual elevation angle is 12.87 degrees
Explanation:
In the attachment you can clearly see the situation. The angle of elevation as seen for the scuba diver is shown in magenta, we conclude that .
Using Snell's Law we can write:
,
Let's approximate the index of refraction of the air (medium 1 in the picture) to 1.
We thus have:
. Calling the actual angle of elevation, we get from the picture that
Given the Hubble's constant, the approximate age of the universe is 5.88 × 10⁹ Years.
Given the data in the question;
Hubble's constant;
Age of the universe;
We know that, the reciprocal of the Hubble's constant ( ) gives an estimate of the age of the universe ( ). It is expressed as:
Now,
Hubble's constant;
We know that;
so
Therefore;
Now, we input this Hubble's constant value into our equation;
Therefore, given the Hubble's constant, the approximate age of the universe is 5.88 × 10⁹ Years.

If velocity is constant, then the object is moving
at constant speed in a straight line.
Answer:
Negative acceleration
Explanation:
We know that
v= u+at
Where v is the final velocity
u is the initial velocity velocity
a is the acceleration
t is time
When final velocity of train will be zero .
v=0
0= u+at
a=- u/t
So from above we can say that acceleration will be negative .When acceleration is positive then train will never come in rest position.
