Answer:
63.36 kJ
Explanation:
Potential energy (PE) is the energy stored within an object, due to the object's position, arrangement or state.
Since the Boulder is now on a height , it has a potential energy
<em>Potential Energy = mass * gravitational acceleration * height</em>
(Assume the gravitational acceleration = 10ms⁻²)
Answer:
Image result for position (m) 80 60 40 20 - 20 -40 10 20 30 40 50 time (sec) What is the displacement from 15 to 40 sec? a 20 m b Оооо - 20 m -100 m с 100 m
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
Explanation:
Magnetic field lines always forms closed loop in such a way that it originates from North pole and then terminates back into the South pole
Inside the magnet we will draw the field lines from south pole to north pole
So it is not possible that magnetic field lines originates from north pole and again terminates at the same pole
So this is
FALSE
Is it the scientific method
Answer:
The show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
Explanation:
From Newton's second law of motion, acceleration is the ratio of applied to mass of the object.
Acceleration is directly proportional to an applied force. At a constant mass, acceleration increases with an increase in the applied force.
Therefore, the show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
