- Assume 1 serving of fried chicken is 320 calories. Consider that a food calorie is equal to about 4 kJ of energy, how much energy in a serving size of the fried chicken compares in other situations. For example, how does this compare to the amount of energy that's necessary to lift a fully-loaded pickup truck up three meters above the ground? Let's say the truck has a mass of 2500 kg. Create a Energy-Interaction Model, and determine how much energy is necessary to lift the truck.Are energy and matter able to be created or destroyed? Yes, they are constantly happening in the world. No, they are both conserved. Possibly, they cannot be proven or denied yet. They can be created, but not destroyed.please answerrrrr asap thank youuu

Relationship of the velocity, maximum energy with it's kinetic and potential energy.Define the Equipartition of Energy ?A projectile hits the ground at an angle of 30 degrees below the horizontal with an energy of 113715 Joules. The mass of the projectle is 0.7kg. Assuming that this projectile was launched from the ground some distance away, determine thet horizontal and vertical velocity components at the launch. Let the acceleration due to gravity be 9.81ms-2 NOTE: sometimes rounding errors can produce slightly different answers, choose the nearest set of values if your answers don't match exactly.

You can find the escape velocity by equating the total kinetic and gravitational potential energy to zero E=12mv2esc−GmM/r=0E=12mvesc2−GmM/r=0 vesc=2GM/r−−−−−−√vesc=2GM/r where GG is Newton's constant of gravitation, MM is the mass of the object from which the escape is happening, and rr is its radius. This is physics you have seen in the first part of the course, and you should be able to use it to find an escape velocity from any planet or satellite. For the Earth, for example the escape velocity is about 11.2 km/s, and for the Moon it is 2.38 km/s. A very important point about escape velocity: it does not depend on what is escaping. A spaceship or a molecule must have this velocity or more away from the center of the planet to be free…
