There are six statements on the list.
The first 2 are true, and the last 2 are true.
The 2 in the middle aren't true. They are false.
In order to solve the problem it is necessary to take into account the concepts related to the moment of inertia, and the center of mass of the object.
Our values are given by:
m = 0.514kg
I = 4.7m (each side)
A) For the case when the axis passes through the midpoints of opposite sidesand lies in the plane of the square. The formula is given by,
B) For the case when the axis passes through the midpoint of one of the sides and is perpendicular to the plane of the square. The formula is given by,
C) For the case when the axis lies in the plane of square f passes through two diagonally opposite particles,
Answer:
0.2695/s
Explanation:
Using the formula for calculating impulse
Impulse = m(v-u) = Ft
M is the mass
v is the final velocity.
u is the initial velocity
F is the force
t is the time
Get the time;
t = m(v-u)/F
t = 0.0055(220)/40
t = 0.0275s
Get the speed of the rifle
v = u+gt.
v = 0+9.8(0.0275).
v = 0.2695m/s
Hence the speed of the rifle is 0.2695m/s
There are two major types of anatomy. Gross (macroscopic) anatomy is the study of anatomical structures that can be seen by the eye, such as the external and internal bodily organs. Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.
Answer is C: Ability to see three-dimensional images of the surfaces of object
Explanation:
To enable the technician see fractures and broken particles in a better resolution as the SEM sees the peaks and valley of the structure.
