Answer:
The total kinetic energy of the system before the collision is 57 Joules.
Explanation:
Given that,
Mass of first block,
Speed of first block,
Mass of second block,
Speed of first block,
We need to find the total kinetic energy of the system before the collision. It is equal to the kinetic energies of both the blocks. It is given by :
So, the total kinetic energy of the system before the collision is 57 Joules.

Answer:
The correct answer is "".
Explanation:
According to the question,
Energy of satellite,
⇒
For the very 1st case:
or,
⇒ ...(1)
For the new case:
then,
⇒
...(2)
From equation (1) and (2), we get
⇒
Machines capable of manufacturing exactly the same component time after time,
with exactly the resistance you want, would be very expensive, and so would the
products they turn out. A resistor would cost a dollar instead of a few pennies.
The machine itself, and its output, work within tolerances.
The cheapest mass-produced resistors are guaranteed to be within 20% above
or below the resistance marked on them. And you know what ? For most bench-
work and prototyping, that's usually close enough.
Answer:
Tables, with their rows and columns of data, interact primarily with our verbal system. We read tables. ... Tables are also handy when you have many different units of measure, which can be difficult to pull off in an easy to read manner in a graph. Graphs, on the other hand, interact with our visual system.
