Third class lever it has the exact resistance
B.sunnny cold probable rain
Answer:
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

Radio-waves
Explanation:
When a police officer uses radar for speed control, the officer is using an electromagnetic radiation known as radio-waves.
- Electromagnetic waves are waves that are produced by the vibration of both magnetic and electrical fields.
- Radar is made up of radio waves.
- Radio waves are classified as non-ionizing electromagnetic radiations.
- The characteristically have long wavelength and low frequency.
- They are often used for long range communication.
- In airports, radio towers uses a radar system to communicate with aircraft.

The sign associated with the average velocity of the object is negative.
<h3>
Average velocity of the object</h3>
The average velocity of the object is calculated as follows;
Average velocity = (v1 + v2)/2
v1 = -20/30 = -0.667 m/s
v2 = 20/50 = 0.4 m/s
Average velocity = (-0.667 + 0.4)/2
Average velocity = -0.134 m/s
Thus, the sign associated with the average velocity of the object is negative.
