D. because the statue has a new chemical called patina. It is no longer copper.
What is your theory on frame of reference?
Answer:
It is the idea of seeing something from a different perspective
Explanation:

To increase the acceleration of the car using the same engine, the mass of the car must be decreased.
<h3>
What is Newton's first law of motion</h3>
Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.
The first law is also called the law of inertia because it depends on the mass of the object. The greater the mass, the greater the inertia and more reluctant the object will be to move.
Thus, to increase the acceleration of the car using the same engine, the mass of the car must be decreased.
a = F/m

The wavelength
of the wave is 160 m, and this is the distance between two consecutive crests. The boat is located at a crest of the wave, this means that the first trough is located 80 meters from the boat (because the distance between a crest and a trough is half the wavelength).
The speed of the wave is
so the time the boat takes to reach the first trough is
P = density × gravity acceleration × height
P = 1200 × 9.81 × 15/100
P = 1765.8
