Answer: The correct statements are:
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.
- Objects are pulled by Earth more strongly than they pull on Earth.
Explanation:
The gravity of the earth is the force which attracts the object to the center of the earth. When the any object with mass falls under the action of the gravity attains the acceleration of 9.8 .

- Objects are pulled by Earth more strongly than they pull on Earth.
Answer:
wavelength = 2.81 m
Explanation:
Given that,
The frequency of the Sports Fan radio station, f = 106.4 MHz
We need to find the wavelength (in meters) of the electromagnetic carrier wave. The relation between frequency and wavelength is given by :
Where,
is wavelength
So, the wavelength of the electromagnetic carrier wave is 2.81 m.
