Answer: Atmosphere and geosphere.
Geo-sphere is the solid part of the earth. Hydrosphere is the water part. The living things on the earth make up the biosphere. The gases, water vapors etc make up the atmosphere. When a volcanic eruption adds carbon dioxide to the air, the carbon-dioxide is being added from geosphere to the atmosphere. Hence, there is interaction between atmosphere and geosphere.
Answer:
859.07 N
Explanation:
u = Initial velocity = 1.9 m/s
v = Final velocity
s = Displacement = 0.165 m
a = Acceleration
m = Mass = 890 kg
Equation of motion

The magnitude of the average force on the bumper is 859.07 N
Answer:
Explanation:
Let the charge on proton be q .
energy gain by proton in a field having potential difference of V₀
= V₀ q
Due to gain of energy , its kinetic energy becomes 1/2 m v₀²
where m is mass and v₀ is velocity of proton
V₀ q = 1/2 m v₀²
In the second case , gain of energy in electrical field
= 2 V₀q , if v be the velocity gained in the second case
2 V₀q = 1/2 m v²
1/2 m v² = 2 V₀q = 2 x 1/2 m v₀²
mv² = 2 m v₀²
v = √2 v₀
Answer:
Explanation:
Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.
Force = mass x acceleration
Apply this equation on Rachel
T₁ = 23 x 2 = 46 N
Let T₂ be tension between Sarah and me and it is inclined at 60°
Force = mass x acceleration
Apply this equation on Sarah
T₂ cos 60 - T₁ = 23 X 2 = 46
T₂ cos 60 - 46 =46
T₂ cos 60 = 92
T₂ = 92 / .5
= 184 N
Explanation:
<em><u>Newton's First Law ,</u></em>
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
