Answer:

The answer is A. Nickel, zinc, and iron

Explanation:

Which example provides a complete scientific description of an object in motion? The hiker followed the north trail a distance of two kilometers in thirty minutes. The tiger had to run at 50 kilometers per hour across the field to catch the zebra. The vibration of the jackhammer broke through the south-facing rock in under 10 seconds. The hockey player sent the puck flying toward the north goal to score the winning point.

Which example describes an acquired trait that cannot be determined by looking at an individual?

Frequency = Velocity / Wavelength = Hz (m/s / m)
Velocity = Wavelength x Frequency = distance/time
Wavelength = Velocity / Frequency = meters (any length)
Step 1: Write down the equation needed to solve for velocity

Velocity = Wavelength x Frequency

Step 2: Place the known measurements into the equation

Step 3: Solve the equation.

Answer all you can please!!

A man uses oars to paddle a boat across a lake, as shown below. The subsequent motion of the boat is best explained by Newton's law of action-reaction. Why? *
A) As each oar pushes the water, the water pushes back, making the boat move forward.
B) The mass of the oars is more than the mass of the man, which makes the boat move forward.
C) The gravitational pull on the oars makes the boat move foward.
D) The water is in motion and will remain in motion until the oars make it stop, pushing the boat forward.
