Because if you increase the surface area of such a fragile object there is more space and in turn more of a chance for the object (in this case the egg) to be damaged.
Answer:
117.88m
Explanation:
We can use the formula [ s = ut + 1/2at^2 ] to solve this problem.
We know that constant acceleration is a = 9/8m/a^2, the initial velocity is 0, and the height is 87 so the only variable we need to solve for is "t".
87 = 0t + 1/2(9.8)(t^2)
t = √174/9.8
t = 4.21s
Now multiply the time by the speed given.
28m/s * 4.21s = 117.88m
Best of Luck!
The answer is DC power had to be converted in AC.
DC power is not usually in home. DC current must be converted to to AC, which is the standard in homes and to avoid short circuits.
DC or direct current explains the basic idea of electricity as a flow of electrons.
AC, also known as alternating current, electricity switches direction around 50-60 times each second. In here, electrons do not necessarily have to run in circles to transport energy, they simply run on the spot.

Main answer: 26.78-kg
Supporting answer: Center of mass
Center of mass of a body is defined as the point at which the whole mass of the body is acting upon. Every body, has its own center of mass. For example, a square has its center of mass at the point where the diagonals of it intersect as well as a circle has its center of mass at the point where it got originated.
All 3-dimensional bodies has 3 axes of rotation. They are x, y and z axes respectively. These axes are used to point the center of mass accurately where it is located.
The co-ordinate in z-axes where the center of mass of a body is found is called as z-coordinate of the mass center(∑).
Now,
We are given with 3 units and its mass. They are:
- Circular disk of 2.5-kg
- Round shaft of 2.5-kg
- Square plate of 3.4-kg
We need to find the z-coordinate of the mass center of these units when present in a 3-dimensional plane.
As the round shaft is placed perpendicular to z plane as it is to hold the square plate we have z value to be 90 for round shaft.
Thus, it can be simplified as:
∑=
Therefore, the value of z-coordinate of mass center is 26.78kg.
