a. 178.5 m
b. 69.97 m/s
c. 7.14 s
<h3>Further explanation</h3>
Given
height = 250 m
vox = 25 m/s
Required
distance from base
vertical speed(vy)
time to reach ground
Solution
voy = 0
h=voy.t + 1/2 gt²
h = 1/2gt²
250 = 1/2.9.8 t²
t=7.14 s
x = vox.t
x = 25 x 7.14
x = 178.5 m
vy = voy + gt(voy=0)
vy = 9.8 x 7.14
vy = 69.97 m/s
Discrete Charge Distribution- means several charges, to determine the effect of all charges you add up their individual effects
Continuous Charge Distribution - charged smeared out long a line , or over a surface or thru a volume of space
Answer:
Answer is C.
Explanation:
To calculate the IMA for a wheel and axle, find the ratio of the larger radius to the smaller radius:
IMA = R/r
IMA = 9/3
IMA = 3
Answer:
For a positive point charge, the lines radiate <u>outwards</u>, while for a negative point charge, the lines converge<u> inwards.</u>
Explanation:
A single point charges produces an electric field which has a radial shape.The sign of a charge determines the the direction of the field. In Positive charge have the direction of field is out of the charge and for negative charge, the direction of field is towards the charge.This behavior is in relation to how a positive test charge will experience in a field.
