Answer: Malleability
Explanation:
Gold in addition to being so rare, is the most malleable element there is. A Malleable element can be shaped and reshaped without it breaking and gold is so malleable that you can hit it till it becomes so flat, its transparent.
This malleability allowed for the ancient peoples to be able to shape and stamp gold into coins and their rarity made them quite valuable. Even today, investors still shape gold into exquisite designs of coins so it not only has monetary value, but aesthetic value as well.
Answer:
The height from which the egg is dropped is <u>68.54 m</u>.
Explanation:
Given:
Initial velocity of egg is, (Dropped means initial velocity is 0)
Time taken is,
Acceleration experienced by egg is due to gravity,
The height from which the egg is dropped is,
Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.
So, we have the following equation of motion:
Plug in all the given values and solve for 'd'. This gives,
Therefore, the height from which the egg is dropped is 68.54 m.
Answer:
Explanation:
Given data
Mass m=5 kg
Moment of Inertia I=0.0648 kg.m²
Radius r=0.18 m
Linear Speed v=4.8 m/s
To find
Total Kinetic Energy K.E
Solution
The total kinetic energy K.E can be found as below
First we need to find the angular speed ω
So
Substitute the angular speed and given values to find total kinetic energy
So
