Answer:
Part a)
A = 0.0581 m
Part b)
T = 0.37 s
Explanation:
A slice is dropped onto the plate from a height of 0.250 m,
therefore the speed of the slice upon impact is calculated as
We know that
Now applying the conservation of momentum:
From this equation, we find:
When the slice rests on the plate, the new mean position can be expressed as
We also determine that the speed of SHM is represented as
Here, we derive values from
Using the previous formula gives:
Part b)
The time period for the scale is computed as
Answer:
Explanation:
Strain is defined as the ratio of an object's dimensional change when subjected to a force:
where
indicates the alteration in length of the object
signifies the object's initial length
In this case, we have and
, hence the strain is
Answer:
Baseball mass:
Explanation:
Circumference of a baseball is calculated using 2πr = 23 cm
Thus, the radius comes out to be 3.66 cm, which equals m
The mass density of the baseball matches that of a neutron or proton.
Proton mass = kg
Proton diameter = m
Proton radius = m
Volume of the baseball is
Now by substituting all values into the mass per unit volume equation for the baseball, we get:
Therefore, the baseball mass amounts to
Response:
Clarification:
Provided
weight of disk
