The magnitude of the gravitational force mars would exert on your body if you were on the surface of mars 252.6 N.

Because it consistently attempts to pull objects together rather than pushing them apart, the gravitation force is known as attractive. It is obvious that the gravitational force directly relates to the masses of the two interacting objects; larger, more massive stars will pull apart with a stronger gravitational force. Because of size of the Earth and how far out from its core humans are on its surface, attraction (or the acceleration caused by gravity) equals 9.81 m / sec squared on Earth's surface.

Newton's Law of Gravitation is used to mathematically determine the force between two bodies.

The complete question is-

Determine the magnitude of the gravitational force Mars would exert on man if he was on the surface of Mars. The mass of the man is 68.0 kg . The mass of the Mars is 6.42×1023kg and its radius is 3396 km

Therefore, the apparent weight of 1.1 g of water is 3.57 N.

What is  apparent weight?

According to physics, an object's perceived weight is a characteristic that describes how heavy it is. When the force of gravity acting on an item is not counterbalanced by a force of equal but opposite normality, the apparent weight of the object will differ from the actual weight of the thing.

given

Speed of rotation, N = 1300 rpm

diameter, d = 35 cm, so that

radius, r = 17.5 cm = 0.175 m

mass of drop = 0.80 g = 0.80 *10^-3 kg

Angular speed of water, ω = 2πN/60

ω = 2π*1300/60

ω = 8169.2/60

ω = 136.15 rad/s

apparent weight will be gotten by

W(a) = mω²r

W(a) =  0.80*10^-3 * 136.15² * 0.175

W(a) =  0.80*10^-3 * 18536.82 * 0.175

W(a) = 3.57 N

Therefore, the apparent weight of 1.1 g of water is 3.57 N.

A space telescope could be a telescope in outer space utilized to watch astronomical objects. Space telescopes avoid the sifting and distortion of electromagnetic radiation which they observe, and maintain a strategic distance from light pollution which ground-based observatories experience. They are divided into two sorts, such as Satellites which outline the entire sky, and satellites which center on selected galactic objects or parts of the sky and beyond.

To distinguish the individual holes, the minimum distance between the person and the tile is 29.8mm ≈30 mm.

Wavelength can be defined as the distances between 2 successively Crest or the  throughs of any wave.

According to Rayleigh's criterion, the angular separation between two point sources is given as follows.

8 = 1.22A d

Here, λ = wave length,

d =circular aperture diameter.

Since the regular separatione is very small, the value of sine is nearby equal to e=㏑

Where D is the center-to-center distance between two point lights and L is the distance from the screen to the light source.

Substitute for e in the above equation 1.22A

8 =d

To obtain the expression for L as

D /L= 1.22A /d

Rearrange the mentioned equation for L as follows:

L = Dd d1.22A

Substitute 0.005m for D, 0.004m for d, and

550 × 10⁻⁹m for λ in the above equation

L = (Dd)/(1.22lambda) to obtain the values of L as follows:

L = ((0.005m)(0.004m))/(1.22(550 × 10 ⁻⁹ m))

L =29.8mm

Answer:-A metal ball is made up of atoms having minimum interatomic distance, so when we heat the metal its atoms actually vibrate about their mean position and thus colliding with neighboring atoms and making them to vibrate, due to this continuation process metals size increases or metal expands on heating.

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space                                                                         “Steel will expand from 0.06 percent to 0.07 percent in length for each 100oF rise in temperature. The expansion rate increases as the temperature rises. Heated to 1,000oF, a steel member will expand 9½ inches over 100 feet of length When a metal ring is heated both inner and outer radii increase. This can be understood better by visualizing that the ring in reality is a rod bent into a circle. That rod will expand upon heating. The same bar bent into a ring thus also expands.

The frequency of the dripping of a leaky faucet which drips 40 times in 30s is 1.3 Hz.

What is frequency?

Frequency is the number of occurrences of a repeating event per unit time. For clarity, this is also called temporal frequency, which is different from angular frequency. Frequency is measured in hertz (Hz) and corresponds to one event per second. Duration is the reciprocal of frequency because duration is the time interval between events.

For example, if his heart beats 120 times per minute (2 hertz), then the period T (interval between repeated beats) is 0.5 seconds (60 seconds divided by 120 beats). Frequency is an important parameter used in science and technology to describe the speed of vibrations and vibrational phenomena such as mechanical vibrations, audio signals (sound), radio waves, and light.

The equipartition theorem predicts that (Vx)²=(Vy)². The average force this wall applies to a particle in a container containing a single particle is independent of Ly& Lz.

The equipartition theorem establishes a connection between a system's temperature and average energy in classical statistical mechanics. Other names for the equipartition theorem include the law of equipartition, the equipartition of energy, and just the word "equipartition." A molecule's average kinetic energy per degree of freedom in translational motion should be equal to that in rotational motion, for example, according to the basic concept of equipartition, which states that energy is distributed equally among all of its many forms in thermal equilibrium.

Quantitative predictions are made using the equipartition theorem. Similar to the virial theorem, it provides the total average kinetic and potential energies for a system at a specific temperature, allowing one to calculate the system's heat capacity. Equipartition, however, also provides the average values for each of the energy's component parts.

Non-ionizing radiation has less energy than ionizing radiation; it does not possess enough energy to produce ions.

Ionizing radiation is capable of knocking electrons out of their orbits around atoms, upsetting the electron/proton balance and giving the atom a positive charge.
