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:
28 metres
Explanation:
when the bag is about to hit the ground
potential energy = kinetic energy
where m = mass
g = acceleration due to gravity
v = speed
when you simplify the above equation and make v subject of the formular we have
where g = 9.8m/s
h = 40
It is an easy to to interpret relationships between dependent and independent variables?
Answer:
There shall be a LABEL
Explanation:
The label is to enable the maintenance personal or the user to identify the individual conductor from each other during removal and installation or when maintenance task is being carried out on the system. This is to avoid the users of the system form plugging the conductor incorrectly.
For example, if there are four conductors label A, B, C, and D there will be four connection point label same way. By this, the user will not plug conductor A to plug B.
Answer:
45.13 beats/min
Explanation:
Speed of space vehicle = 0.51c
the pulse rate measured by the astronaut= 61.0 beats per minute
Pulse rate measured by the Earth observer is given by
putting vales we get
= 45.13 beats/min
