Answer:
9.8m/s^2 down (option C)
Explanation:
The only acceleration acting on this motion case in the acceleration due to gravity: 9.8 m/s^2 in the downwards direction.
Answer:
(a) α = 35.20 rad/s^2
(b) θ = 802°
(c) v = 139.73 cm/s
(d) a = 156.64 cm/s^2
Explanation:
(a) To find the angular acceleration of the disc you use the following formula:
(1)
w: angular speed of the disc = 31.4 rad/s
wo: initial angular speed = 0 rad/s
t: time = 0.892s
You replace the values of the parameters in the equation (1):
The angular acceleration of the disc, for the given time, is 35.20rad/s^2
(b) To calculate the angle describe by the disc in such a time you use:
(2)
In degrees you have:
The angle described by the disc is 802°
(c) To calculate the tangential speed of the microbe for t=0.892s, you use the following formula:
(3)
w: angular speed for t = 0.892s = 31.4rad/s
r: radius of the disc = 4.45cm
The tangential speed is 139.73 cm/s
(d) The tangential acceleration is calculated by using the following formula:
α: angular acceleration for t=0.892s
The tangential acceleration is 156.64cm/s^2
Answer:
Fluorine and sodium
Explanation:
Fluorine has 2,7 remaining one valance electron to be balance and sodium has 2,9 in which it will lose one too for both of them to be balanced so fluorine atom will receive 1 valence electron from sodium atom so they can both be balanced
<span>The Average Distance from Uranus to the Sun is 27.506. One way to solve this is by doing the oppsite of how you find the orbitial period. The way you find the orbitial period is by raising the distance to the 3rd. So what i did was take the square root of the orbitial period which is 9.16 and multiplied it by 3 to get 27.506.
