Answer:
Plant cells contain cell structures like cell wall, plastids, and large vacuoles. Cell wall provide plant cells rigidity and structural support and cell to cell interaction. Plastids help in storage of plant products. Chloroplasts aid in carrying out the process of photosynthesis to produce food for the plants.
Explanation:
The dependent variable was the time and the independent variable was thecars
B) Light slows down when it passes into a denser medium.
The fusion reaction that is easiest to accomplish is the reaction between two hydrogen isotopes: deuterium, extracted from water and tritium, produced during the fusion reaction through contact with lithium. When deuterium and tritium nuclei fuse, they form a helium nucleus, a neutron and a lot of energy.
Answer:
0.16joules
Explanation:
Using the relation for The gravitational potential energy
E= Mgh
Where,
E= Potential energy
h = Vertical Height
M = mass
g = Gravitational Field Strength
To find the vertical component of angle of launch Where the angle is 22°
h= sin theta
So E = mghsintheta
= 0.18 x 0.98 x 0.253 sin22
=0.16joules
