Answer:
2.Scientists discovered new evidence to support their theories.
3.Scientists discovered that old interpretations of data was incorrect.
4.Scientists used observations and mathematical data to solve problems in new ways.
Explanation: Here you go
d = 400 m (8 laps) = 2400 m
t = 14.5 min
v = 0
average t = 14.5 min (60 sec per min) = 870 s/8 laps = 108.75 s per lap
speed = distance /time
400/108.75 sec = 3.67 m/s
Answer:
Solar Nebula
Explanation:
~About 4.6 billion years ago, the sun and planets formed together from a cloud of dust and gas in which was called the solar nebula.~
~The cloud surrounded the sun in a crust and then it broke apart, according to theory.~
Hope this Helps!
Answer:
Explanation:
From the question we are told that
Mass of block
Radius of circle
Force of track
Normal Force on block
Generally the equation for Velocity of block is mathematically Given by the law of conservation of energy
For initial velocity
0.660 = 0.0425 x u^2/0.525 - 0.0425 x 9.8
Generally the equation for work done is mathematically Given by
Answer:
If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
Explanation:
R₁ = Resistance of first resistor
R₂ = Resistance of second resistor
V = Voltage of battery = 12 V
I = Current = 0.33 A (series)
I = Current = 1.6 A (parallel)
In series
In parallel
Solving the above quadratic equation
∴ If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
