Answer:

Models have always been important in science and continue to be used to test hypotheses and predict information. Often they are not accurate because the scientists may not have all the data. It is important that scientists test their models and be willing to improve them as new data comes to light.

If a farsighted person has a near point that is 0.600 mm from the eye, what is the focal length f2f2f_2 of the contact lenses th
Readme [11.4K]

Answer:

0.22mm

Explanation:

A far sighted person is a person suffering from long sightedness i.e such individual can only see far distant object clearly but not near distant object. The defect is corrected using convex lens.

Since convex lens is used, the focal (f) length of the lens is positive and the image distance (v) is also positive.

Using the lens formula,

1/f = 1/u + 1/v

Where u is the object distance = 0.35mm

v = 0.6mm

1/f = 1/0.35+1/0.6

1/f = 2.86 + 1.67

1/f = 4.53

f = 1/4.53

f = 0.22mm

The focal length of the contact lenses will be 0.22mm

A current of 02kA is traveling through a circularly looped wire. The wire makes 35 turns around an induced magnetic field of 8 9
PIT_PIT [208]

Answer:

The radius of the loop is 4.94\times10^{5}\ m

Explanation:

Given that,

Current = 0.2kA = 200 A

Number of turns = 35

Magnetic field = 8.9 nT

We need to calculate the radius of one loop

Using formula of magnetic field

B=\dfrac{N\mu_{0}I}{2r}

r=\dfrac{N\mu_{0}I}{2B}

Where, I = current

N = number of turns

B = magnetic field

r = radius

Put the value into the formula

r=\dfrac{35\times4\pi\times10^{-7}\times200}{2\times8.9\times10^{-9}}

r =494183.11\ m

r=4.94\times10^{5}\ m

Hence, The radius of the loop is 4.94\times10^{5}\ m

You place a book on top of a spring and push down, compressing the spring by 10 cm. When you let go of the book, it is pushed up
Zinaida [17]
At First, there is chemical Energy( in your muscels) which is Used to Push down the spring. This Energy becomes the Energy of the spring, which increases until you stop pushing. If you Put your hand away, the Energy of the spring will become kinetic energ. This Energy is at the highest Level the Moment the book ist Leaving the spring. Afterwards, the kinetic Energy decreases while the Gravitational Potential Energy increases.

You have developed a method in which a paint shaker is used to measure the coefficient of static friction between various object
Paladinen [302]

Answer:

0.62

Explanation:

A = Amplitude

f = Frequency = 1.85 Hz

\mu = Coefficient of static

g = Acceleration due to gravity = 9.81 m/s²

Angular frequency

\omega=2\pi f\\\Rightarrow \omega=2\pi\times 1.85

Maximum acceleration

a_{max}=A\omega^2\\\Rightarrow a_{max}=0.045\times (2\pi\times 1.85)^2

a_{max}=\mu g\\\Rightarrow \mu=\frac{a_{max}}{g}\\\Rightarrow \mu=\frac{0.045\times (2\pi\times 1.85)^2}{9.81}\\\Rightarrow \mu=0.62

Coefficient of static friction between penny and tabletop is 0.62
