Answer:
there is no diagram, but i can try to help
Explanation:
strong winds bonding together (i.e hot and cold) help form the tornado, depending on the weather depends on how long it can go on, if more hot and cold are feeds into it, it will get faster and last longer. it is just like dust devils, it is wind and dirt mixing to make a tornado, the more wind and dirt the worst it will be
Answer:
a. 11.5kv/m
b.102nC/m^2
c.3.363pF
d. 77.3pC
Explanation:
Data given
to calculate the electric field, we use the equation below
V=Ed
where v=voltage, d= distance and E=electric field.
Hence we have
b.the expression for the charge density is expressed as
σ=ξE
where ξ is the permitivity of air with a value of 8.85*10^-12C^2/N.m^2
If we insert the values we have
c.
from the expression for the capacitance
if we substitute values we arrive at
d. To calculate the charge on each plate, we use the formula below
Answer:
Diathermy and atmospheric pressure
Explanation:
When the energy from the Sun comes to the Earth, it hits first the atmosphere, but the air contained is almost unaffected by it because the molecules are not tight enough to absorb its incoming energy.
Later on, the sunlight reaches the soil, thus absorbing part of the energy and reflecting the rest. Because of this reflection, the air near to the ground begins to heat through convection and as it gains height the air pressure (thus the air molecules begin to separate more from each other) decreases and the energy transfer to them is more difficult. As a result, as you gain height, the air temperature decreases at a rate of 6.8 ºC every 1,000 meters.
Answer:
gs = 0.6 m/s^2
Explanation:
Given data:
velocity = 12 m/s
height s = 12t -(1/2) g_s t^2
Given velocity is the derivatives of height
when velocity tend to 0 , maximum height is reached
at t = 20 sec ball reached the max height, so
Answer:
D Magnesia
Explanation:
Ore particles Fe3O4 (magnetite) were found in the region called Magnesia.
Magnesia was an antic city in Asia, named after the inhabitants of Greek Magnesia.
Magnetite is used as an ore, abrasive, in paint production, electrophotography, as a micronutrient fertilizer, and as a high-density concrete aggregate.
