Air pollution. Specifically the compounds sulfur dioxide and nitrogen oxide released from the burning of fossil fuels (source of air pollution), can find their way high into the atmosphere, where the compounds mix with with water, oxygen, and other chemicals to form more acidic pollutants (acid rain).
Answer:
You drive 60 miles in one hour if you drive at 60 miles an hour. You are traveling at one mile a minute.
Explanation:
You would travel one mile if you move at one mile an hour.
Using the Einstein relationship:
<span>Nuclear binding energy = Δmc^2 </span>
<span>number of protons x 1.007825 x 931.5 Me V = X </span>
<span>number of neutrons x 1.008665 x 931.5 Me V = Y </span>
<span>Adding up these energies = X + Y </span>
<span>59.933820 x 931.5 Me V = Z </span>
<span>Subtract Z from (X+Y)
</span>
<span>(X+Y) -Z = Nuclear binding energy
</span><span>Divide by the total number of nucleons by the sum of all protons and neutrons in Co 60
</span>
<span>(524.807 Me V)/(60 nucleons) = 8.74678 Me V/nucleon.</span>
Distance 1=98km,time 4 hrs
distance 2=99km,time 1 hrs
total distance travelled /total time taken.
98+99=197/4+1=5
average speed=39.5km per hour
Answer:
Speed of the car around the circular path will be 12 m/sec
Explanation:
We have given mass of the car m = 1500 kg
Radius of the curve r = 45 m
Centripetal acceleration of the car
We have to find the speed of the car
We know that centripetal acceleration is given by , here v is car speed along the circular path and r is radius of the curve
So
v = 12 m/sec
So speed of the car around the circular path will be 12 m/sec
