Answer: An archer pulls her bowstring back 0.400m by exerting a force that increases uniformly from zero to 230N. The equivalent spring constant of the bow will be 575N/m
Explanation: To find the answer, we have to know about the Simple Harmonic Motion.
<h3>What is Simple Harmonic Motion?</h3>
- A particle is said to execute simple harmonic motion, if it moves to and fro about mean position under the action of restoring force.
- The restoring force is directly proportional to its displacement from the mean position and always directed towards the mean position.
- If x is the displacement from the mean position, and F is the restoring force, then
∝
where, k is called the spring constant.
<h3>How to approach the problem?</h3>
- Given that, an archer pulls her bowstring back 0.400m by exerting a force that increasing from zero to 230N.
- Here, from the question given, we can write,
and
. - Thus, our spring constant k will be,

Thus, we can conclude that, the equivalent spring constant of the bow will be 575N/m.

Answer:
The mass of the object is 49.5kg which is approximately 50kg
Explanation:
Given that
Spring constant (k)=45N/m
The extension (e)=0.88m
Also given that the acceleration is 0.8m/s²
Force by the spring is given as
Using hooke's law
According to Hooke's law which states that the extension of an elastic material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically,
F = ke where
F is the applied force
k is the spring constant
e is the extension
From the formula k = F/e
F=ke
m is the mass of the block = ?
a is the acceleration = 0.8m/s²
e is the extension of the spring = 0.88m
k is the spring constant = 45N/m
F=45×0.88
F=39.6N
Now this force will set the object in motion, now using newton second law of motion
F=ma
Then, m=F/a
m=39.6/0.8
m=49.5kg
The mass of the object is 49.5kg which is approximately 50kg
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
How the light affect the color we see?
All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected.
Answer:
C
Explanation:
Nuclear waste must be safely stored for many years because it is bad to store that much nuclear waste.
