In reality we don't see the galaxy we see it's reflection .. the light hits or got emitted by the star travel all the way long to hit our eyes .. we see their reflection . everything around you that you see is it's reflection
Answer: Smoke is Abiotic because it is not a living thing.
Explanation: Hopefully this helps u. Have a great rest of your day. I hope this is the right answer
Answer:
C) specific heat capacity
Explanation:
As we know that heat given to the system to change the temperature is given as

here we know that
Q = thermal energy given to the system
s = specific heat capacity of the system
= change in temperature
so here we know that

here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)
So correct answer would be
C) specific heat capacity
Answer:
v₀ = 15 m/s
Explanation:
given,
initial velocity = v₀
down acceleration of rock = 10 m/s²
rock distance
S₄ = 7 x S₁
From kinematic equations
S = v₀ t+0.5 at²
at t = 1 s
S₁ = v₀ (1)+0.5 x 10 x 1²
S₁ = v₀+ 5......(1)
at t = 4 s
S₄ = v₀ (4)+0.5 x 10 x 4²
S₄ = 4 v₀+80.....(2)
from equation (1) and (2)
7( v₀ + 5 ) = 4 v₀ +80
3 v₀ = 80 - 35
3 v₀ = 45
v₀ = 15 m/s
The vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.
The forces exerted on an object can be resolved into <em>horizontal</em> and <em>vertical components.</em>
<em />
The horizontal components of the forces on an object being pulled include the following;
- The frictional force on the object; which tends to reduce the motion,
- force dragging the object forward
- if the object is inclined to an angle, the horizontal component of the weight
This horizontal force is written as;

The vertical component of the force on the object include the following;
- the weight of the object acting downwards
- the pull of air on the object acting upwards
The vertical force on the object is written as;

Thus, the vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.
