A. The magnitude of the spring force (in N) acting upon the object is 15.9 N
B. The magnitude of the object's acceleration (in m/s²) is 30.58 m/s²
C. The direction of the acceleration vector points toward the equilibrium position (i.e., to the left in the figure).
<h3>A. How to determine the force </h3>
- Extension (e) = 0.150 m
- Spring constant (K) = 106 N/m
- Force (F) = ?
F = Ke
F = 106 × 0.15
F = 15.9 N
<h3>B. How to determine the acceleration</h3>
- Mass (m) = 0.52 Kg
- Force (F) = 15. 9 N
- Acceleration (a) =?
F = ma
Divide both sides by m
a = F / m
a = 15.9 / 0.52
a = 30.58 m/s²
<h3>C. How to determine the direction of the acceleration vector</h3>
Considering the diagram, we can see that the spring was pulled away from the equilibrium point.
Thus, when the spring is released, it will move toward the equilibrium point. This is also true about the acceleration.
Therefore, we can conclude that the direction of the acceleration vector is towards the equilibrium point.

Answer:
The time of short pulse of light beam is 
Explanation:
Given that,
A beam of light from a laser illuminates a glass.
Suppose, the length of piece is 
Index of refraction is 2.83.
We need to calculate the speed of light pulse in glass
Using formula of speed
Put the value into the formula
We need to calculate the time of short pulse of light beam
Using formula of velocity
Put the value into the formula
Hence, The time of short pulse of light beam is
Answer:
zero
Explanation:
There are three forces acting on the piston
1. force due to atmospheric pressure = F1 downward
2. force due to gaseous pressure = F2 upward
3. force due to the weight placed on the piston = F3 = mg downward
As the piston is in equilibrium condition, so the net force on the piston is zero.
