Answer:
they were in two places in flint and Birmingham and in Birmingham it is hot but flint of cold the Simi is they both have Sunday school for Joetta
Explanation:
use in your own words teachers know when your not trust me.
Over the course of a long drive, as a result of alternating between braking and acceleration and of course steering, tires get heated up. When this happens, the air within the tires gets heated up, causing the air within the tire to expand. This expanding air exerts force on the tire from inside thus increasing tire pressure.
Answer:
(a)
vf_1s = 5.19 m/s
h_1s = 10.095 m
vf_4s = 24.23 m/s
h_4s = 4.49 m (below railing)
(b)
vi = 9.9 m/s
(c)
t = 1.53 s
h = 34.41 m
Explanation:
(c)
First, we will use the 1st equation of motion to find the time to attain the highest point:
where,
t = time to attain maximum height = ?
vf = final velocity = 0 m/s (ball momentarily stops at highest point
vi = initial velocity = 15 m/s
g = - 9.81 m/s (for upward motion)
<u>t = 1.53 s</u>
Now, for the height attained we will use the 2nd equation of motion:
<u>h = 34.41 m</u>
(b)
using the 3rd equation of motion for a height of 5 m:
<u>vi = 9.9 m/s</u>
<u></u>
(c)
At t = 1 s:
<u>vf_1s = 5.19 m/s</u>
<u></u><u></u>
<u>h_1s = 10.095 m</u>
<u></u>
At t = 4 s:
Since the ball covers the maximum height of 34.41 m in 1.53 s and then starts moving downward.
Therefore for the remaining 4 s - 1.53 s = 2.47 s, the initial velocity will be 0 m/s at the highest point and the value of g will be positive due to downward motion.
<u>vf_4s = 24.23 m/s</u>
<u></u><u></u>
now, for the position with respect to railing:
<u>h_4s = 4.49 m (below railing)</u>
<u></u>
Answer:
Yellow
Explanation:
Since red, green, and blue are primary colors of light, yellow is the only option which is not. So, yellow is not a primary color of light.
