Answer:
a = -5/6 m/s²
Explanation:
v² = u² + 2as
a = (v² - u²) / 2s
a = (0² - 5²) / 2(15)
a = -5/6 m/s²
This assumes the initial velocity was in the positive direction.
Answer:
The answer is Current.
Explanation:
In a series circuit, every component will have the same <u>current</u>.
In parallel circuit, all <u>voltage</u> of component remains the same.
Answer:
Acceleration is 
Solution:
As per the question:
Radius of the circle, R = 1.8 m
Height above the ground, h = 1.8 m
Horizontal distance, x = 9.9 m
Now,
The magnitude of the centripetal acceleration can be calculated as:
where
v = velocity
R = radius
= centripetal acceleration
Now, if we consider the vertical component of motion only, then considering the initial velocity, 'u' = 0, from kinematic eqn:
t = 0.606 s
Now, for the horizontal component of velocity:
x = vt
Now, we know that the centripetal acceleration is given by:
The answer is; The entropy of steam is larger than because it is more disordered than ice
Entropy is synonymous to the degree of disorder or randomness of molecules in a system. The molecules of steam are far apart from each other and move randomly in the system colliding with each other. Those of ice has less kinetic energy, vibrate more or less in a fixed position in the structiure, and are arranged in a orderd fashion
Answer:
Geometrical optics, or ray optics, describes the propagation of light in terms of "rays" which travel in straight lines, and whose paths are governed by the laws of reflection and refraction at interfaces between different media.
