I think B is the most correct, because logically it's harder to bend a stiffer spring than it is to bend a softer one. Also, I don't think length comes into play. So B.

Answer:

B. The stiffer the spring, the greater the force required to restore its position.

Explanation:

The 'restoring force' (the force required to restore the position of a spring) is given by:

F=-kx

where

F is the restoring force

k is the spring constant, which determines its stiffness (the higher the value of k, the stiffer the spring)

x is the displacement of the spring relative to its natural length

From the formula, we see that the higher the value of k (so, the stiffer the spring), the larger the restoring force, so the correct option is

B. The stiffer the spring, the greater the force required to restore its position

What are the four types of musical instruments and what are the physical behind each type of musical instrument
pishuonlain [190]

Answer:

The four types of musical instruments are percussion, woodwind, brass, and strings.

Explanation:

Percussion instruments include drums, triangle, cymbals, and xylophones. There are more instruments than what i've mentioned though. Percussion instruments often produce the beat of songs.

Woodwind instruments include clarinets, oboe, flute, and saxophone. Woodwind instruments often produce the harmony of songs and, occasionally, the melody.

Brass instruments include trumpet, trombone, french horn, and tuba. Brass instruments often produce the harmony of songs, the trumpet produces the melody a lot though.

String instruments include guitars, violins, cello, bass, ukulele, and banjo. String instruments produce both the harmony and the melody. These instruments often produce really beautiful music, in my opinion.

After it was discovered, astronomers predicted Uranus's orbit using Newton's laws of motion and gravity, which had worked extrem
kotykmax [81]

Answer:

A. Check for other previously undiscovered factors that might alter Uranus's orbit while still allowing it to obey Newton's laws of motion and gravity.

Explanation:

Uranus behaved in a way that Newton's laws of motion could not explain. But this law predicted very well the behavior of other planets, so it could not be totally wrong or discarded, so it was decided to look for whether there was a planet beyond Uranus, which would alter its movement. The search was done and this is how <u>Neptune </u>was discovered, and by adding the attraction that Neptune would have on Uranus, its orbit could be calculated correctly by Newton's laws of motion.

Since Newton's law of gravitation had worked so well it was more likely that there were unknown factors that would alter his movement, rather than the laws no longer working or the data being wrong.

Later Newton's law of gravitation was modified by Einstein to take into account the effects of relativity. But Newton's laws work very well to describe the solar system.

You place a penny on a turntable at a distance of 14.3 cm from the center. The coefficient of static friction between the penny
S_A_V [24]

Answer:

Time will be 2.13 sec

Explanation:

We have given that distance r = 14.3 cm ==\frac{14.3}{100}=0.143m

Coefficient of static friction \mu =0.4

Angular acceleration is given by \alpha =2.45rad/sec^2

We know that frictional force is given by F=\mu mg

And centrifugal force is given by F=\frac{mv^2}{r}

When coin just starts moving

\mu mg=\frac{mv^2}{r}

We know that v=\omega r , here \omega is angular velocity

According to first equation of motion we know that

\omega =\omega _{i}+\alpha t

As \omega _i=0

so \omega =\alpha t

\mu g=\frac{\left ( r\alpha t \right )^2}{r}

\frac{\mu g}{r}=a^2t^2

t=\frac{\sqrt{\frac{\mu g}{r}}}{α}

t=\frac{\sqrt{\frac{0.4\times  9.8}{0.143}}}{2.45}=2.13sec
