Chicxulub. It's the most famous cataclysm ever, the meteorite that probably snuffed out the dinosaurs (along with three-quarters of all life on Earth) when it smashed into our planet 65 million years ago. The crater it left behind is actually one of the youngest and most accessible in the solar system.
The gravitational potential energy is 252 J
Explanation:
The Gravitational Potential Energy (GPE) of an object is given by

where
W is the weight of the object
h is the height of the object above the ground
For the carriage and the baby in this problem, we have
W = 21 N is their weight
h = 21 m is their height above the ground
Substituting,

Answer:
1.10134 * 10⁻⁹m⁻¹
Explanation:
K = 680Nm⁻¹
μ = ?
μ = (m₁ + m₂) / m₁m₂
compound = CO
C = 12.0 g/mol = 0.012kg/mol
O = 16.0g/mol = 0.016kg/mol
μ = (m₁ + m₂) / m₁m₂
μ = (0.012 + 0.016) / (0.012*0.016) = 145.83
v = 1/2πc * √(k/μ)
ν = 1/ 2*3.142* 3.0*10⁸ * √(630/145.83)
v = 5.30*10⁻¹⁰ * 2.078
v = 1.10134*10⁻⁹m⁻¹
Answer:
According to Newton's first law of motion, an object will experience a change in motion if the forces are unbalanced.
