Potential Energy (Initial one) = m * g * h
P.E. = 60 * 9.8 * 10
P.E. = 5880
Kinetic Energy (Final One) = 1/2 mv²
K.E. = 1/2 * 60 * (10)²
K.E. = 6000/2
K.E. = 3000
Lost Energy = 5880 - 3000 = 2880 J
In short, Your Answer would be 2880 Joules
Hope this helps!
Answer:
Time period of the motion will remain the same while the amplitude of the motion will change
Explanation:
As we know that time period of oscillation of spring block system is given as
now we know that
M = mass of the object
k = spring constant
So here we know that the time period is independent of the gravity
while the maximum displacement of the spring from its mean position will depends on the gravity as
so we can say that
Time period of the motion will remain the same while the amplitude of the motion will change

Answer: The Systeme international (International System of Units
)</h2>
The International System of Units (SI) is used in almost every country in the world (<em>except Burma, Liberia and the United States</em>).
This system was created in 1960 by the 11th General Conference of Weights and Measures in France and is made up of seven basic units:
-Ampere (electric current)
-Kelvin (temperature)
-Second (time)
-Meter (length)
-Kilogram (mass)
-Candela (luminous intensity)
-Mol (amount of substance) *added to the system in 1971
Plus an unlimited number of derived units from the main ones.
A complex machine is a machine made up of two or more simple machines that make your work easier to do. There are six simple machines from which all complex machines are made. They include: The lever. The inclined plane
