while discovered less than 100 years ago isotopes are now used in a wide variety of scientific applications that touch the lives of almost every citizen.
The main cause of weather is uneven heating of the earth's surface.
There are various factors that contribute to weather, however the main factor is the uneven heating of the earths surface. This creates temperature differences and can cause water to evaporate and condense. This, combined with earth's spin lead to large scale weather systems and wind currents. These in turn are influenced by land forms, bodies of water, and even vegetation.
Iron is considered a micro-nutrient because only small amounts are required to aid in normal plant growth. ... Plants can suffer iron deficiency with symptoms of chlorosis and stunted growth, but plants can also take in too much iron, especially under certain growing conditions.
Answer:
<em>a. q=450 c
</em>
<em>b. E=675 J
</em>
Explanation:
<u>Direct Current (DC)
</u>
It's the flow of electric charges in one direction driven by a constant voltage circuit. The intensity of the current flow is computed as
Where q is the constant flow of charge in time t
The energy of an element providing Voltage V, current I during a time t is
a. The charge can be computed by solving the first equation for q
b. The energy transferred by the battery is
Stress = force / area
= 4.8 x 10³ / 1.2 x 10^-4
= 4 x 10⁷ N /m²
YOUNGS MODULAS = stress / strain
= 4 x 10⁷ / 1.2 x 10^11
= 3.3 x 10^-4
INCREMENT OF LENGTH = longitudinal length x intitial length
= ( 3.3 x 10^-4 ) x 4
= 13.2 x 10^-4 m
= 13.2 mm
