An object oriented database model allows containers like sets and lists, arbitrary user-defined datatypes as well as nested objects. This brings commonality between the application type systems and database type systems which removes any issue of impedance mismatch.

If an object is moving at a constant speed the force of friction must equal the applied (horizontal) force, and for it to be accelerating or decelerating, the force of friction and the applied force must be unequal. Also, I know that f = μ N.

This distance, called an astronomical unit (AU), is a standard measure of distance for astronomers and astrophysicists. An AU can be measured at light speed, or the time it takes for a photon of light to travel from the sun to Earth. It takes light about eight minutes and 19 seconds to reach Earth from the sun. The radius

Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch.

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law.

Explain why weight of an object on moon is only (1)/(6)th of the weight of the object on earth. 642959894. 03:53.

State Archimedes’ principle Describe the relationship between density and Archimedes’ principle When placed in a fluid, some objects float due to a buoyant force. Where does this buoyant force come from? Why is it that some things float and others do not? Do objects that sink get any support at all from the fluid?

Since the gravitational force of the moon is1/6th that of the earth ,therefore , the weight of an object on the moon is 1/6th of its weight on the earth . The mass and radius of moon are less than that of earth due to which the moon exerts a lesser gravitational force on objects (which is1/6 th of that exerted by the earth).

Describe an object you find particularly beautiful. Well, it’s hard for me to choose a beautiful thing to tell. That’s because almost every day I come across a lot of interesting things. But right now, I would like to talk about a clock that hangs in my living room. In fact, I would say it is a masterpiece of art.

Much like a File instance is not a file. So, Thread.currentThread () is a way for you to retrieve the instance of Thread in charge of the thread-of-execution inside which the method is called. How exactly Java does this is an implementation detail which should not be your concern unless you are exploring the details of a particular JVM.

Solution Verified by Toppr Correct option is C) Suppose the original momentum of the body to be ‘p’ and a 50 % increase leads to amomentum of p+ 10050 p=1.5p The relation between momentum ‘p’ and kinetic energy ‘k’ is p 2=2km (m is mass of object) hence k= 2mp 2 New kinetc energy k= 2m(1.5p) 2 ( as new p is 1.5p) k=2.25× 2m(p 2)=2.25×k

Work Done by a Force. The work done by a force is the integral of the force with respect to displacement along the path of the displacement: W AB = ∫ pathAB →F ⋅d→r. W A B = ∫ path A B F → · d r →. The vectors involved in the definition of the work done by a force acting on a particle are illustrated in (Figure).
