In Newtonian mechanics, it has been said that two bodies exert a force of gravitation on each other. Let’s take an example of Solar System In our solar system Earth goes around the Sun. Per Newtonian Mechanics Sun exert a larger amount of attractive gravitational force in turn creates a centripetal force on Earth since Earth’s velocity is much greater and perpendicular to that of gravitational pull. But As Einstein worked on general theory of relativity, he realized that there occurs a distortion in the fabric of space-time due to massive objects. It can also be interpreted in this way, set a large body in the centre of a trampoline.
Mass effects the physics of the projectile. Also, it greatly effects the trebuchet because the counterweights mass. Also, gravity plays an important role in the physics of the trebuchet as well. For example, it effects the projectile while in mid-flight. It it also brings the counterweight down to make the other end go up.
The reason atoms need heat is because heat gives the atoms energy which causes them to move to an excited and then back to ground state. The longest wavelength of radiation to break a single O2 molecule is approximately 242 nanometers. This wavelength is ultraviolet which would come from the
The Maxwell Distribution Curve below supports the prediction about the increase of temperature, increasing the rate of reaction. Curves T1 and T2 show the distribution of kinetic energies for gaseous at those two temperatures. Curve T2 represents a higher temperature and thus is positively skewed. The peak of the graph with the most molecules is shifted towards a higher kinetic energy and the curve broadens out. For both T1 and T2, the total area under the curve is the same and the fraction of molecules with energy greater than the activation energy (Ea) is significantly larger in T2 than in T1.
Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered. Some factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will
High-mass stars have a few similarities to low-mass stars, as they are both created from an interstellar cloud collapsing, and they go through similar phases, but high mass stars are different from low-mass stars because they are born from larger clumps than ones that create stars similar to the sun. Because the clump is greater and its mass is greater too, which causes it to squeeze more and in doing so heats up the star more than the sun. Therefore, when the star reaches the main sequence stage of its life it is way hotter, more luminous and blue. When a star has such a high luminosity it means that it will burn through it’s fuel, hydrogen, faster so instead of it taking 10 billion years to use all its hydrogen, it actually uses up the fuel in 100 million years or less depending on the star. This causes the star to age significantly faster and once it runs out of hydrogen it begins to grow bigger in size and cool down like a low-mass star, although the massive star goes through the pulsating yellow giant phase before it can reach the red giant stage.
Method: We first measured for x, R’, and R_sun–for both the initial and final positions of the sunspot. Since both the Earth and the sun orbit, our perspective that we observe the sunspots change. Because the sun and Earth are both spheres on a tilted rotational axis (we must keep in mind that this is from the horizontal and ‘bird’s eye-view’ of the sun), we solved for the longitudinal angles of both the initial and final sun spot positions using the following formulas: θ=sin〖x/(R ')〗 〖θ=sin〗〖x/R_sun 〗 To find ω_S, we must correct for Earth’s orbit because the sun moves at a faster rate than the Earth. To do so, we find ω_E, which is 2.0 x 〖10〗^(-7)rad/s, and ∆ω_OS, using the equation ∆ω_OS=∆θ/∆t . We can substitute the angular velocities of the Earth and the observed angle into the equation ω_S=ω_E+Δω_OS, to find the true angular velocity of the sun.
According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3). Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which
When heat is added to the gas inside the bottle, it expands. This expansion provides a force that inflates the balloon by pushing it outwards against the force exerted by the atmosphere. Hence, the heated gas does work on the balloon. This illustrates the first law of thermodynamics, which is centered on the relationship between heat and work. Besides this, another law of thermodynamics can be seen in the movement of gas particles from a higher temperature reservoir to a lower temperature reservoir.
