Answer:
so to find the acceleration we divide the change in velocity by the time taken for it so intial velocity was 3m/s and final velocity is 10m/s. we substract 3 from 10 to get the change in velocity ie 10m/s -3m/s = 7m/s. now decide this by the time taken for it that is 4 sec as given. acceleration is 7/4 = 1.75m/s^2
Answer:
a = 7.4 m / s²
Explanation:
The centripetal acceleration of an object that has constant speed is
a = v² / r
linear and angular velocity are related
v = w r
let's substitute
a = w² r
the angular velocity is related to the period
w = 2π / T
we substitute
a =
let's calculate
a = 4π² 3.00 /4²
a = 7.4 m / s²
Answer:
Complete question:if a = 0.800 cm? (μ0 = 4π × 10-7 T · m/A)
Explanation:
Given:
Distance between plates = 0.8 cm
Distance from one plate = 1 mm
Current density 'J'= 16 A/m
Currents are flowing in opposite direction.
When current is flowing in opposite direction then magnetic field given as
By putting the values we get
