Milankovitch cycles are based on the variations in the orbit of the Earth around the sun and the precession of the axis of the Earth. These cycles are used to explain the cold and warm climates cycles that characterizes during the ice age.The cycles in this are results of the changes in the orbit of the Earth around the sun which includes it eccentricity, shape, the tilt of the axis and its obliquity.
Answer:
Explanation:
Given that,
Mass of cannon is,M = 2000 kg
Mass of projectile, m = 2 kg
Velocity of the projectile, v = 200 m/s
We need to find the kinetic energy of the projectile. We know that the formula for the kinetic energy of an object is given by :
or
So, the kinetic energy of the projectile will be .
Answer: I'm sure the answer is a.
Explanation: I hope that helped you.
<span>A roller coaster with a potential energy of 235,200 J and sits at the top of a 30 m high hill has a mass equivalent to 799.18 kg. Using the formula of PE = mgh, all of the values are already known, so direct substitution can be used. PE is the potential energy, m is the mass, g is gravitational constant (9.81 m/s2), and h is the height.</span>
