Answer:
A. Scientists use seismic computer models to measure the atmospheric conditions above the Earth's crust
Explanation:
why would use atmosphere to study the layers of earth? dont think thats possible
Answer:
Explanation:
From work energy theorem
Work done by all forces = Change in kinetic energy
Lets take
m= mass of object
h=height from the ground surface
initial velocity of object = 0 m/s
The final velocity of object is v
Work done by gravitational force = m g . h
The final kinetic energy = 1/2 m v²
So
Work done by all forces = Change in kinetic energy
m g h = 1/2 m v² - 0
v² = 2 g h
Answer:
The bulb B glows brighter.
Explanation:
Given that,
A glows brightly and B glows dimly.
According to ohm's law,
Two light bulbs A and B are connected in series to a battery then the current will be same in both bulbs and the resistance is high of bulb A and low in bulb B.
If bulb A connect to a battery and bulb B connect to a same battery separately.
Then bulb B glows brighter because the resistance is high in bulb A so the current will be low.
The resistance is low in bulb B so the current will be high.
Hence, The bulb B glows brighter.
Electrons that are the highest energy level is called Valence Electrons
Gamma rays can pass through a lot
