List three equations (relationships) describing free falling objects in gravitational fields.

The correct answer for the wavelength (405 or 500 nm) based on our evaluation of the absorption spectrum just taken is 405 nm which is Fluorescence .

Fluorescence diagnosis could improve the safety and reliability of stereotactic brain tumor biopsies performed with biopsy needles equipped with integrated fiber optics. Vital tumor tissue can be localized in vivo during the excision procedure using 5-aminolevulinic-acid-induced protoporphyrin IX (PpIX) fluorescence, reducing the number of samples required for a reliable diagnosis. On optical phantoms, the practical suitability of two different PpIX excitation wavelengths (405 nm, 633 nm) was investigated. Violet excitation at 405 nm provides a 50-fold increase in sensitivity for the bulk tumor; ray tracing simulations show that this factor increases up to 100 with decreasing fluorescent volume.

Nicolaus Copernicus advocated that the Earth and all other planets orbits around the sun in circular paths at uniform speeds.

Nicolaus Copernicus named this model as Copernicus's Heliocentric Model in 1543. Until his theory was published, it was believed that the Earth is the center of the solar system and the sun moves around it.

The mistake in his theory is that the orbits are circle in shape whereas the correct shape is elliptical which was later corrected by Kepler's model in 1609 which was later proved by Galileo Galilei with the help of telescope.

Therefore, Nicolaus Copernicus advocated that the Earth and all other planets orbits around the sun in circular paths at uniform speeds.

No, the bullet is not likely to be manufactured by Winchester.

Given:

X = 936

S=10\ss=10

We are unable to use the empirical rule since we do not know if the distribution is symmetric or skewed.

According to Chebyshev’s rule, which states that at least 89% of the data values are contained within 3 standard deviations of the mean, can be used to help us.

Overline x 3s=936 3(10) = 906 x 3s = 936 3(10) = 906

Overline x +2x = 936 + 3 (10), which becomes x +2x = 936

Thus, between 906 and 966 is the range for at least 89% of the velocities.

Empirical principle approximately 68.3 percent of the values in a data set with a symmetric distribution will be within one standard deviation of the mean, approximately 95.4 percent will be within two standard deviations of the mean, and approximately 99.7 percent will be within three standard deviations of the mean.

Usual values fall within 3 standard deviations of any mean and 1000 does not come within 3 standard deviations of the mean, thus it is unlikely that the bullet with velocity 1000 feet per second was manufactured by Winchester.

The maximum speed by which a ball is thrown vertically upward is 34.1255 ft/sec.  as the height in the given data is 18.1 ft.

In physics, vertical launch upward may be characterized as the motion that is illustrated by an object that has been set afloat vertically upwards in which the height and the consequences of the earth's gravitational force set in motion of an object are taken into consideration.

According to the question,

The formula for the vertical launch upward may be as follows:

where v₀ = initial velocity

           g = gravity max = maximum height.

We know that,

g = 32.17 ft/s²

On applying the formula of maximum speed and clearing the initial velocity we get:

y max = v₀²/(2*g)

v₀ = √(y max * (2*g)

v₀ = √( 18.1 ft * (2 * 32.17 ft/s²)

v₀ = √( 18.1 ft * 64.34 ft/s²)

v₀ = √1164.554 ft²/s²v₀ = 34.1255 ft/sec.

Therefore, the maximum speed by which a ball is thrown vertically upward is 34.1255 ft/sec.  as the height in the given data is 18.1 ft.

The correct option is (b) 5n

As a result, there is a net downward force of 5N operating on the object.

The resultant force is the force that results from adding the vector sums of all the forces operating on an item. The combined action of all the acting forces on the object produces the same effect as the resulting force. When determining the resulting force, the direction of the forces must be taken into account.

Given;

The northward force is Fn = 10N

The southward force is Fs = 15N

Required;

The net force on the mobile phone is Fnet = ?N

The object's weight exerts downward pressure, and upward resistance exerts upward pressure. The vector sum of these two forces will be the net force.

Fnet = Fs - Fn (Considering the direction downward as positive)

Fnet= 15N - 10N

Gasoline is already considered frozen if it turns into a thick sludge or wax. To totally avoid frozen gasoline inside the car, focus on preventing the fuel line from freezing during winter. Stale gasoline can be dangerous as it contains a combination of over 150 chemicals that can destroy both animal and human lives.

The mass of the object is 13.924 lbf.

Using the formula:

w = m x g ....... eq1

here w is weight of the object.

m is mass of the object, and

g is the acceleration of gravity.

acceleration of gravity, g= 32.0 ft/[tex]s^{2}[/tex]

Now, substituting the values in equation (1):

w = 14lbm x 32.0 ft/[tex]s^{2}[/tex] = 448 lbm ft/[tex]s^{2}[/tex]

since, 1 lbf = 32.174 lbm ft/[tex]s^{2}[/tex]

The number of vanadium atoms are 9769230.

To find the number of vanadium atom, the given values are,

radius of vanadium atom = 130 pm

distance = 2.54 mm

Let us assume that a vanadium atom has a spherical shape.

diameter of a sphere = 2 x radius of the sphere

Thus,

Radius of a vanadium atom = 130 pm

                                             = 130 x 10⁻¹² m

The diameter of a vanadium atom = 2 x radius

                                                         = 2 x 130 x 10⁻¹²

                                                         = 260 x 10⁻¹² m

Given a distance of 2.54 mm = 2.54 x 10⁻³ m,

The number of vanadium atoms required to span the distance,

= ( 2.54 x 10⁻³ m) / ( 260 x 10⁻¹² m)

The earth diameter is about 3 and 2 thirds times the diameter of the moon. what is the angular diameter of the earth seen by an observer on the moon?

We calculate the angular diameter of the Earth using the equation:

a=arctanD/d

where a is the angular diameter, D is the physical diameter of the Earth, and d is the distance from the Moon to the Earth.

The equatorial radius of the Earth is rE=6378.1km, the diameter is therefore

D=2×rE=12756.2.

   The mean distance to the Moon is d=384399km. This gives a (mean) angular diameter of a=1.90065°.

At Perigee the distance is d=362,600km. This gives an angular diameter of a=2.01482°

At Apogee the distance is d=405,400km. This gives an angular diameter of a=1.80226°

These Moon-Earth distances are as seen from the centre of the Moon. To calculate the diameter from the surface of the Moon, to subtract the position of the observer along the Moon-Earth axis.

If the observer is on the Moon's equator and the Earth is at zero-hour angle, the distance to the Earth needs to be subtracted by rM=1738.14km. Thus, we have;

 The mean distance to the Moon is d=384399−1738=382661km, giving an angular diameter of a=1.90928°.

At Perigee the distance is d=362600−1738=360862km. We have an angular diameter of a=2.02452°

At Apogee the distance is d=405400−1738=403662km. We have an angular diameter of a=1.81001°

The angular diameter of the Earth from the surface of the Moon is, therefore, between a=1.80226° (at apogee and the Earth is near the horizon) and a=2.02452° (at perigee and for an observer at the equator and when the Earth is at maximum altitude on the meridian).
