Answer:
255 metres
Explanation:
The answer to thi question is actually quite simple. Since the car goes for 3.4 seconds, and it goes 75 metres every second, the answer is just 3.4 multiplied by 75 Metres.
1. Amperes, is the SI unit (also a fundamental unit) responsible for current.
2.
Δq over Δt technically
Rearrange for Δq
I x Δt = Δq
1.5mA x 5 = Δq
Δq = 0.0075
Divide this by the fundamental charge "e"
Electrons: 0.0075 / 1.60 x 10^-19
Electrons: 4.6875 x 10^16 or 4.7 x 10^16
3. So we know that the end resistances will be equal so:
ρ = RA/L
ρL = RA
ρL/A = R
Now we can set up two equations one for the resistance of the aluminum bar and one for the copper: Where 1 represents aluminum and 2 represents copper

We are looking for L2 so we can isolate using algebra to get:

If you fill in those values you get 0.0205
or 2.05 cm
Answer:
Final velocity will be 314.6 m/sec
Distance traveled = 1314.24 m
Explanation:
We have given initial velocity u = 233 m/sec
Acceleration 
Time t = 4.8 sec
From first equation of motion
, here v is final velocity, u is initial velocity and t is time
So 
Now we have to find distance traveled
From second equation of motion

So distance traveled in given time will be 1314.24 m
Answer:
The value is 
Explanation:
From the question we are told that
The average acceleration of the bicycle is
The initial forward velocity is 
Generally from kinematic equations we have that

Here v is the final velocity of the bicycle and the value is v = 0 m/s
So

=> t = 18.6 s
The existence of photosynthetic organisms, particularly the blue-green algae, are the organisms responsible for changing the early atmosphere of the Earth. These organisms came from rock formations found throughout Earth and are responsible for feeding off on the carbon dioxide that was abundant in its atmosphere. As they have learned to feed-off carbon dioxide, they in turn have transformed this compound and produced oxygen.
Scientists have also proven that rocks and other sediments contained abundant amounts of trapped oxygen. Through time when the rocks have withered and formed into sediments these oxygen gases are released into the air and got trapped within the atmosphere overpowering the levels of carbon dioxide.
This phenomenon is very important throughout the history of Earth because the Earth became a habitable planet where several species can thrive. This phenomenon has also led to the several geographical changes that the Earth has undergone to because it cooled-down its overall temperature.
