In the World Pond Hockey tournament held in Plaster Rock, NB, a puck on the ice travels 20.0 m [25° W of N], gets deflected, and travels 30.0 m [35° N of W]. Determine where the puck will end up with respect to its starting point, e.g., the puck's total displacement, using the three different methods discussed.
Answers
Basically, the problem asks you to find the resultant (R) vector quantity, which is the displacement. Illustrate the problem. Then, find the missing angles. In this case, the angle opposite to R is 150 degrees. Then, using the cosine law:
R = 48.36 m

Further Explanation
Gravity or gravity is the attraction that occurs between all particles that have mass in the universe. Sun's gravity causes celestial bodies to be in their respective orbits around the sun. Modern physics describes gravity using Einstein's Theory of General Relativity, but Newton's simpler universal law of gravity is a fairly accurate estimate in many cases.
For example, the earth which has a very large mass produces a very large gravitational force to attract objects around it, including living things, and objects that exist on earth. This gravitational force also attracts objects in space, such as the moon, meteors, and other celestial bodies, including man-made satellites.
Kinetic energy or motion energy (also called kinetic energy) is the energy possessed by an object because of its motion.
The kinetic energy of an object is defined as the effort needed to move an object with a certain mass from rest to a certain speed.
The kinetic energy of an object is equal to the amount of effort required to express its speed and rotation, starting from the others.
Modern research in the theory of gravity began with the work of Galileo Galilei in the late 16th century and early 17th century. With the results of his experiments dropping the ball from the Tower of Pisa, and then also measuring the ball sliding through the slope, Galileo showed that the magnitude of gravitational acceleration was the same for all objects. This is a big advance from Aristotle's earlier belief that heavier objects have greater gravitational acceleration.

Answer:
The equation of amount of electrical energy used .
d is correct option.
Explanation:
Electrical energy :
The electrical energy is the chemical energy which is consumed in the electric circuit.
Power :
Electric power is the rate at which energy is transferred from one part to another part of electric circuit.
The amount of electric energy is defined as,
The amount of electrical energy is the product of the power and time.
Where, E = energy transferred
P = Power
t = time
Hence, The equation of amount of electrical energy is used .
cause E=U and in power formula is p=U÷t or E÷t so E=p×t

The electromagnet can be adjusted for having different levels of magnetic fields by turning it on and off. Hence, option (D) is correct.
What is an Electromagnet?
Electromagnets are made by winding a wire through a magnetic material such as a soft iron core making a coil and then passing an electric current through the coil thus making the soft iron core magnetic.
The characteristics of electromagnets are as follows -
- The strength of the electromagnet depends on the number of coils and also the size of the electric current through the coil.
- Permanent or regular magnets on the other hand do not require power but depend on the type of material used to make it.
- It is advantageous to use electromagnets as compared to using permanent magnets since the strength of the electromagnet can be easily adjusted by regulating the amount of current flowing through the coils.
Thus, we can conclude that the electromagnet can be adjusted for having different levels of magnetic fields by turning it on and off. Hence, option (D) is correct.
