🔑:If all matter were to annihilate with all antimatter in a universe where they are present in equal amounts, the resulting state of the universe would be one of pure radiation, consisting entirely of photons. This is because when matter and antimatter particles collide, they release their entire rest mass energy in the form of photons, according to Einstein's famous equation E=mc^2.In this scenario, the universe would be left with no matter or antimatter particles, only photons. The total energy of the universe would remain constant, but it would be converted entirely into the kinetic energy of photons. This is because the energy-momentum relation for photons is given by E = pc, where p is the momentum of the photon and c is the speed of light. Since photons have zero rest mass, their energy is entirely kinetic.The implications of this scenario for our understanding of energy and momentum are significant. Firstly, it highlights the concept of mass-energy equivalence, where mass can be converted into energy and vice versa. In this case, the rest mass energy of matter and antimatter particles is converted into the kinetic energy of photons.Secondly, it demonstrates the conservation of energy and momentum in the universe. Even though the matter and antimatter particles annihilate, their energy and momentum are not lost, but rather converted into a different form. This is a fundamental principle in physics, and it has far-reaching implications for our understanding of the behavior of particles and the evolution of the universe.The concept of baryogenesis, which refers to the process by which the universe came to be dominated by matter over antimatter, would also be affected by this scenario. In the standard model of cosmology, baryogenesis is thought to have occurred in the early universe, resulting in a slight excess of matter over antimatter. However, if all matter were to annihilate with all antimatter, the universe would be left with no net baryon number, and the concept of baryogenesis would become moot.In terms of the energy-momentum relation for photons, the scenario highlights the unique properties of massless particles. Photons have zero rest mass, but they still carry energy and momentum. This is in contrast to particles with mass, which have a non-zero rest mass energy. The energy-momentum relation for photons, E = pc, shows that their energy is directly proportional to their momentum, and that they always travel at the speed of light.In conclusion, if all matter were to annihilate with all antimatter in a universe where they are present in equal amounts, the resulting state of the universe would be one of pure radiation, consisting entirely of photons. This scenario highlights the concepts of mass-energy equivalence, conservation of energy and momentum, and the unique properties of massless particles like photons. It also has implications for our understanding of baryogenesis and the energy-momentum relation for photons.It's worth noting that this scenario is highly hypothetical, as the universe is not observed to have equal amounts of matter and antimatter. The observed universe is dominated by matter, with antimatter being relatively rare. The reason for this asymmetry is still not fully understood and is the subject of ongoing research in cosmology and particle physics.

🔑:The primary factors that govern the trajectory of shrapnel upon the explosion of a stationary explosive device are:1. Initial Velocity: The speed at which the shrapnel is ejected from the explosive device. This velocity is determined by the energy released during the explosion and the mass of the shrapnel.2. Angle of Ejection: The direction in which the shrapnel is ejected from the device. This angle determines the initial trajectory of the shrapnel.3. Air Resistance: The force exerted by the air on the shrapnel as it travels through the atmosphere. Air resistance slows down the shrapnel and affects its trajectory.4. Gravity: The downward force exerted by the Earth's gravity on the shrapnel. Gravity pulls the shrapnel towards the ground, affecting its trajectory.Conservation of Momentum:The explosion of the device imparts momentum to the shrapnel, which is conserved as the shrapnel travels through the air. The momentum of the shrapnel is given by:p = m * vwhere p is the momentum, m is the mass of the shrapnel, and v is its velocity.Initial Velocity:The initial velocity of the shrapnel is determined by the energy released during the explosion and the mass of the shrapnel. The kinetic energy of the shrapnel is given by:KE = (1/2) * m * v^2where KE is the kinetic energy, m is the mass of the shrapnel, and v is its velocity.Air Resistance:Air resistance slows down the shrapnel and affects its trajectory. The force of air resistance is given by:F_d = -½ * ρ * v^2 * C_d * Awhere F_d is the force of air resistance, ρ is the air density, v is the velocity of the shrapnel, C_d is the drag coefficient, and A is the cross-sectional area of the shrapnel.Gravity:Gravity pulls the shrapnel towards the ground, affecting its trajectory. The force of gravity is given by:F_g = m * gwhere F_g is the force of gravity, m is the mass of the shrapnel, and g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth).Trajectory of Shrapnel:The trajectory of the shrapnel can be modeled using the following equations:x(t) = v_0 * cos(θ) * ty(t) = v_0 * sin(θ) * t - (1/2) * g * t^2where x(t) and y(t) are the horizontal and vertical positions of the shrapnel at time t, v_0 is the initial velocity, θ is the angle of ejection, and g is the acceleration due to gravity.Influence of Air Resistance:Air resistance slows down the shrapnel and affects its trajectory. The effect of air resistance can be modeled using the following equation:v(t) = v_0 * e^(-β * t)where v(t) is the velocity of the shrapnel at time t, v_0 is the initial velocity, β is a constant that depends on the air density and the drag coefficient, and t is time.Diagram:A diagram of the trajectory of shrapnel can be represented as follows:In this diagram, the shrapnel is ejected from the explosive device at an angle θ and with an initial velocity v_0. The shrapnel travels through the air, affected by air resistance and gravity, and eventually hits the ground.In conclusion, the primary factors that govern the trajectory of shrapnel upon the explosion of a stationary explosive device are initial velocity, angle of ejection, air resistance, and gravity. The principles of conservation of momentum, initial velocity, and air resistance influence the path of the shrapnel, and can be modeled using equations and diagrams to predict the trajectory of the shrapnel.

🔑:## Step 1: Convert the initial speed of the car from km/h to m/sFirst, we need to convert the initial speed from km/h to m/s. The conversion factor is that 1 km/h is equal to 1000 m/3600 s, which simplifies to 5/18 m/s. Therefore, 90 km/h is equal to 90 * (5/18) = 25 m/s.## Step 2: Calculate the acceleration of the carTo find the acceleration of the car, we use the formula F = ma, where F is the force applied (2200 N), m is the mass of the car (760 kg), and a is the acceleration. Rearranging the formula to solve for a gives us a = F / m = 2200 / 760 = 2.895 m/s^2.## Step 3: Calculate the distance traveled during the driver's reaction timeThe driver's reaction time is 0.55 s. During this time, the car continues to travel at its initial speed of 25 m/s. The distance traveled during the reaction time is given by d = v * t = 25 * 0.55 = 13.75 m.## Step 4: Calculate the time it takes for the car to come to a stop after the brakes are appliedWe use the equation v = v0 + at, where v is the final velocity (0 m/s), v0 is the initial velocity (25 m/s), a is the acceleration (-2.895 m/s^2, negative because it's deceleration), and t is the time. Rearranging the equation to solve for t gives us t = (v - v0) / a = (0 - 25) / -2.895 = 8.64 s.## Step 5: Calculate the distance traveled while the car is deceleratingUsing the equation d = v0*t + 0.5*a*t^2, where d is the distance, v0 is the initial velocity (25 m/s), t is the time (8.64 s), and a is the acceleration (-2.895 m/s^2), we can find the distance traveled during deceleration. However, a more straightforward approach given we already have the initial and final velocities and the acceleration is to use the equation v^2 = v0^2 + 2*a*d, rearranged to solve for d gives d = (v^2 - v0^2) / (2*a). Substituting the known values gives d = (0^2 - 25^2) / (2 * -2.895) = 625 / 5.79 = 108.0 m.## Step 6: Calculate the total distance traveled before coming to a stopThe total distance traveled is the sum of the distance traveled during the reaction time and the distance traveled while decelerating. Total distance = 13.75 m + 108.0 m = 121.75 m.The final answer is: boxed{121.75}
