The arrow should point in the direction the object is accelerating.
Answer:
Angular velocity of tire
Explanation:
Given:
Diameter of tire of an automobile =75.0 cm
Linear velocity of automobile = 90.0 km/hr
To find angular velocity of tire.
Diameter of tire in meters =
Radius of tire =
Linear velocity in meters per second =
Angular velocity is given by :
where represents linear velocity and represents radius of tire.
Plugging in values.

If two sources emit waves with the same wavelength and a constant phase difference ϕ, they are said to be coherent.
<h3>What is coherent source ?</h3>
- If the frequency and waveform of two wave sources are the same, they are coherent. Waves' optimal quality of coherence makes stationary interference possible.
- When the phase difference between two beams of light is constant, they are coherent; if the phase difference is random or changes, they are noncoherent.
- The concept of a superpositioning at the core of quantum physics and quantum computing is referred to as "quantum coherence." Quantum coherence specifically considers a scenario in which a wave property of an item is split in two and the two waves coherently interfere with one another.
- The interference visibility, which examines the size of the interference fringes in relation to the input waves, is an easy way to measure the degree of coherence; correlation functions provide a precise mathematical definition of the degree of coherence.
