Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!

Answer:
1.28 s
Explanation:
Given:
Δy = 8 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(8 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.28 s

Answer:
The evidence that supports the wave particle nature of light as a wave is:
"Light reflects when it hits a surface."
Explanation:
Light exhibit wave-particle duality. This means, in some cases the properties of light are just like a wave and in other cases it behaves as particles.
The properties like reflection or refraction from a surface are attributed as properties of waves. The phenomena of interference and diffraction also fall in this category.
Therefore, from the given options, the only option that supports the evidence of light as a wave is "Light reflects when it hits a surface", as reflection is entirely the property of a wave.
