The car reaches its top speed when the constant thrust force equals the opposing air resistance force, resulting in zero net external force and constant velocity. This balance between thrust and resistance forces determines the top speed.
When the applied thrust force typically supplied by the engine equals the total of the opposing forces pushing on the vehicle, the vehicle reaches its maximum speed.
Air resistance, or drag, is the main opposing force and it grows as the car's speed squares. The car first accelerates because the propulsion force overcomes this resistance as it accelerates. But the air resistance force likewise increases with the car's speed until it reaches the same level as the thrust force.
The car now maintains a steady velocity when it reaches its maximum speed and the net external force acting on it zeroes. The maximum speed is also influenced by other elements like mechanical efficiency and rolling resistance.

Answer:
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth
Explanation:
Answer:
No
Explanation:
becuse it's not even outer space there's acceleration there's no such thing as Zero acceleration speed except if you're not in motion.
B) burning paper
C) film being exposed to light
D) a piece of paper being cut in half
b) The wavelength doubles
c) The speed of the wave doubles
d) The wavelength is cut in half
e) The speed of the wave is cut in half
Doubling the frequency of a transverse wave on a string would result in the wavelength of the wave being halved. This is due to the inverse relationship between frequency and wavelength in the context of wave speed remaining constant.
When considering a transverse wave travelling on a string, if the frequency is suddenly doubled, then the wavelength would be cut in half rather than any other given option. This is because the speed of a wave is determined by the medium through which it travels—in this case, the string—rather than its frequency or amplitude. Because the speed remains constant when the frequency doubles, the only factor left to adjust is the wavelength, according to the wave speed equation 'v = fλ', where 'v' is wave speed, 'f' is frequency, and 'λ' is wavelength. Thus, frequency and wavelength have an inverse relationship: if frequency increases (doubles, in this case), wavelength must decrease (halve) to maintain the constant wave speed.
