Answer:

Explanation:

Newton's law of universal gravitation is that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Answer:

157.5

Explanation:

X=vi *t + 0.5*a*t^2

vi=12, t=7, a=3

x= 12*7 + 0.5*3*7^2

= 84+ 73.5= 157.5 m

If we use visible light to explore the sky, a greater part of the universe will not be visible.

During her PhD, Walker learnt that the universe is quite large. As a result, she would need a telescope to learn about the universe rather than a spaceship. Secondly, she learnt that it is impossible to explore the universe on a spaceship rather she had to depend on the principles of astronomy.

The visible spectrum comprises of electromagnetic waves of wavelength 400 nm - 700 nm. If we use visible light to explore the sky, a greater part of the universe will not be visible because we will be limited to seeing only the  visible light portion of the electromagnetic spectrum.

Answer:

Only part of the incident energy from an X-ray source may be used by the ejected electron (some of the energy can be used by the exiting photo electron and some of the energy by the exiting photon).

Auger electrons depend on the energy difference between energy levels of an atom and are fixed - so the ejected electron will have a fixed energy depending on the difference of energy levels of the atom. The Auger effect is called a "radiationless" transition because no radiation is detected outside of the atom.

If both masses double in size and their separation between them triples. 13..33 N will be the force between the masses.

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

Given data:

The gravitational force = 30 N

Mass 1 =m₁

Mass 2=m₂

Distance between charges = R

Condition given:

Mass 1 = 2m₁

Mass 2= 2m₂

Distance  between charges = 3R

[tex]\rm F = \frac{Gm_1m_2}{R^2}[/tex]

Case 2;

[tex]\rm F'=\frac{G(2m_1)(2m_2)}{(3R)^2} \\\\ F'=\frac{4}{9} \frac{Gm_1m_2}{R^2} \\\\ F'=\frac{4}{9} F \\\\ F'=\frac{4}{9} \times 30 \\\\ F'=13.33 \ N[/tex]

Hence, the forces between the masses will be 13..33 N.

When the experimental measurements diverge at very low values of the voltages. When the ratio of current to saturated current is very small. That is, i/I less than or equal to 1/100. When there is a finite current at Voltage

V = 0

Diffusion will have influence on current - voltage curve in the working electrode which is ionization detector.

The estimation under set of conditions that is possible, despite the spherical shape of the working electrode, to use linear diffusion equations to theoretically predict the current vs voltage curve expected in this experiment will be:

Where

i = electric current

I = saturated current

V = voltage supplied

The curve expected will therefore give exponential curve from positive to negative domain because of the diffusion of ions from different directions

The velocity and acceleration of the particle moving round the circle is;

Velocity = 162.12 m/s

Velocity = 162.12 m/sAcceleration = 6.873 × 10^(-5) m/s²

We are given;

Radius of circle; 382400 km = 382400000 m

Time; t = 27.3 days = 27.3 × 86400 s = 2358720 s

Now, formula for velocity is;

Velocity = distance/time

Thus;

I) velocity = 382400000/2358720

Velocity = 162.12 m/s

II) Acceleration is centripetal acceleration and is given by the formula;

a = v²/r

a = 162.12²/382400000

a = 6.873 × 10^(-5) m/s²

Based on geographical analysis, the earthquakes affect the rise and progress of the civilization in America and the Pacific islands by causing slope failures, liquefaction, and tsunami.

The effect of earthquakes in America and the Pacific Islands has caused people displacement as buildings collapsed, and water from nearby oceans caused the destruction of physical properties.

For safety reasons, when a natural disaster like an earthquake occurs in your place, you are expected to stay away from buildings if you're outside.

Similarly, if you are in a car, you should stop and pull over.

If you are in bed during the earthquake, wrap your head and neck with a pillow while turning your head upside.

Also, avoid doorways or windows if you are inside.

Considering the three types of waves, the most destructive wave is known as surface waves.

Surface waves have the most potent vibrations and can travel through any earth surface, whether air or water.

Other types of waves include Transverse waves and Longitudinal waves.

Hence, in this case, it is concluded that the effect of earthquakes is negative on human society, and waves can be destructive.

There is one theorem - whose proof I will never remember without having to drag calculus in there - that says that the variation of momentum is equal to the force applied times the time the application last.

[tex]F\Delta t = m \Delta v[/tex] As long as the engine isn't ejecting mass - at this point it's a whole new can of worm - we know the force, we know the variation in speed, time to find the mass. But first, let's convert the variation of speed in meters per second. The ship gains 250 kmh, [tex]\Delta v = 69.4 m/s[/tex];
