Answer:
9m is this the way calculator its acceleration
Answer:
53.36 m.
Explanation:
Initial velocity of the toolbox u = 0
acceleration due to gravity g = 9.8 m s⁻²
time t = 3.3 s
height of roof h = ?
h = ut + 1/2 g t²
= 0 + .5 x 9.8 x 3.3²
= 53.36 m.
A. an accelerating charged charged particle or changing magnetic fields
Answer:
2880 N/c
Explanation:
Given that:
Charge per unit length ; λ = 4 * 10^-9
radius, r = 10
Radius, R = 0.5m
Using the relation :
2λr / 4πE0R²
Columb's constant, k = 1/4πE0 =. 9* 10^9Nm²/C²
Hence, we have :
2λrk/ R²
(2 * 4 * 10^-9 * 10 * 9 * 10^9) / 0.5^2
(720 ÷ 0.25)
= 2880 N/c
