The gas planets usually have extremely high gravitational pulls, the surface isn't solid (since its a gas planet), and gas planets are larger than the inner planets.
<span>Similarities- These planets all have moons and they both revolve around the sun (obviously).
Hope this helps.</span>
This is the definition of specific heat capacity. 1000J of heat are required to raise the temperature of 1kg of the compound by 1 degree. Therefore a 1000J have been added to the block.
Answer:
D)80/10 × 5 × 10^-4 N m^-2
Explanation:
this is the answer that was on my assignment
c is physical ie not chemical reaction ...
mass cannot be created or destroyed. in chem reaction, mass before reaction = total mass after. that would incl any gas
water. find the mass of, say, 100cc. divde the mass by the volume.
water = 1000kg/cubic metre. a lot of water ...
Since the two charts after the collision stick together, we are dealing with a perfectly inelastic collision.
First, we need to find the speed of the two charts after the collision. In order to do so, we consider the conservation of momentum:
m₁·v₁ + m₂·v₂ = (m₁ + m₂)·v
We can solve for v, considering also that v₂=0
v = m₁·v₁ / (m₁ + m<span>₂)
= 0.31 </span>· 0.90 / (0.31 + 0.50)
= 0.34 m/s
The kinetic energy lost (which is transformed into bounding energy between the two charts) will be the difference between the total kinetic energy before the collision and after the collision:
ΔE = E₁ - E₂ = 1/2·m₁·v₁ - 1/2·(m₁ + m₂)·v
= 1/2(0.31)(0.90) - 1/2(0.81)(0.34)
= 0.1395 - 0.1377
= 0.0018J
Hence, the correct answer is ΔE = <span>0.0018J</span>
