Answer:
t=2.10 s
u= 47.40 m/s
Explanation:
given that
h= 21.8 m
x= 101 m
g=9.8 m/s²
Lets take horizontal speed of ball = u m/s
The vertical speed of the car at initial condition is zero ( v= 0).
We know that
v= 0 m/s
now by putting the values
21.8 = 1/2 x 9.8 x t²
t=2.10 s
This is time when ball was in motion.
Now in horizontal direction
x = u .t
101 = u x 2.1
u= 47.40 m/s
Answer:
If there is a system of magnets being held in place, there is potential energy. When you let go, the potential energy converts to kinetic energy and the magnets move. Putting the system of magnets close together which creates an opposing force.
Explanation:
Water can contain dillute chemical solutions that can dissolve rock such as hydrochloric acid working against limestone
Answer:
Freeze Fracture replication
Explanation:
<u>Freeze Fracture replication</u> is a technique that allows investigation of the microheterogeneity of a membrane so that one can see localized differences in different parts of the membrane.
Freeze fracture replication is a technique used with electron microscopy to splits frozen cell membranes apart for visualization of the membrane structure and the organization of proteins within the sea of phospholipids.
The four steps in making a freeze-fracture replication are
(i) rapid freezing,
(ii) fracturing,
(iii) replication and
(iv) replica cleaning.
