That's true.
Magnets attract some metals such as iron, nickel, etc.
Hope this helps~
Answer:
Explanation:
The period of oscillation is given as
T=2π√m/k
Making k subject of the formula
Square both sides of the equation
T²=4π²(m/k)
Cross multiply
T²k=4π²m
Then, divide through by T²
k=4π²m/T²
Where
k is spring constant
m is the mass of the bob
And T is the period of the oscillation
m=140g=0.14kg
14 oscillations takes 14 seconds
Then the period is
T=time/oscillation
T=14/14
T=1sec
Then,
k=4π²m/T²
k=4π²×0.14/1²
k=1.76N/m
Then, the spring constant is 1.76N/m
Answer:
Yes
Explanation:
Science is a quest to find answers and patterns in the universe which can then be relied on for predicting future occurrence. Finding these singular points or at least to some extent, the cause and formation of this point will help with our further and deeper understanding of the universe, and we can then be able to predict when, where or when this singularities occurs.
Answer:
No
Explanation:
Spending a lot of time on these singularities that are hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe is an absolute waste of time. This reflects no practice of science, since science is all about finding answers. If these answers we seek to find no matter how much we probe, cannot be gotten from further studies of these occurrences then it will be best to leave what can't be found. The fact that all known laws of physics breaks down at these point is a pointer that any physical means that will be employed to probe these singularities will yield no result within our known physical laws.
I will go with yes, with hope that advance in science will someday break these barriers or reconcile our known laws of physics with whatever physical law prevails within these singularities.
Answer:
Explanation:
Possible causes for overcurrent include short circuits, excessive load, incorrect design, an arc fault, or a ground fault. Fuses, circuit breakers, and current limiters are commonly used overcurrent protection (OCP) mechanisms to control the risks
