Answer:
Fundamental frequency= 174.5 hz
Explanation:
We know
fundamental frequency=
velocity =
mass per unit length=
=0.00427
Now calculating velocity v=
=244.3
Distance between two nodes is 0.7 m.
Plugging these values into to calculate frequency
f = 
=174.5 hz
Answer:
<em>The correct option is D) fruit</em>
Explanation:
Both the gymnosperm and the angiosperms plants produce seed. Seeds are an essential part of reproduction in plants.
After fertilization has occurred, the ripened ovule is the part which turns into a seed. The size of the seeds depends on the type if plant.
After fertilization, the ovary forms the fruit. As the ovule is present in the ovule hence after fertilization, the seed which was made from the ovule gets enclosed in the fruit which was made from the ovary.
Answer:
Explanation:
We know that from Newton's second law of motion, F=ma hence making acceleration the subject then 
where a is acceleration, F is force and m is mass
Also making mass the subject of the formula 
For 
and 
hence 
Answer:
B. Geosphere
A. Biosphere
A. Atmosphere
Explanation:
Volcanic eruptions occurs within the Geosphere. The geosphere is the rock solid earth make up of rocks that extends into the deep interior.
Magma formed deep within the crust rises to elevated parts and finally erupts as lava on the surface. When they cool, they solidify to form volcanic rocks.
The volcanic eruptions affects the biosphere significantly. The biosphere is the portion of the earth where all life forms exists.
Gases and ash spewed during an eruption into the atmosphere causes severe changes to weather and leads to pollution. The atmosphere is the gaseous envelope round the earth.
