Determine the acceleration of a raptor that reaches 25 m/s from rest in 6.5 s.

3.8 m/s²

Explanation:

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (25 m/s − 0 m/s) / 6.5 s

a ≈ 3.8 m/s²

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
