A :-) for this question , we should apply
a = v - u by t
Given - u = -2 m/s
v = -10 m/s
t = 16 sec
Solution -
a = v - u by t
a = -10 - -2 by 16
a = -12 by 16
( cut 12 and 16 because 2 x 6 = 12 and
2 x 8 = 16 )
( cut 6 and 8 because 2 x 3 = 6 and
2 x 4 = 8 )
a = 3 by 4
a = 0.75 m/s^2
.:. The acceleration is 0.75 m/s^2.
The doppler effect has red and blue shifts. A red shift means something is moving farther away, and a blue shift means it is moving closer. The universe has a red shift, and since a red shift means that it is moving farther away, this tells astronomers that the universe is still expanding.
Answer:
b
Explanation:
it compresses hot air turning into cool air almost like a reverse tornado
The two units are Inches of Mercury and Millibars
Answer:
y = 2.76 [m]
Explanation:
We can find the distance of the fall of the apple using the following kinematic equation, we have to emphasize that this is a typical problem of free fall, so the initial speed is zero, then we give the initial data.
t = time = 0,75[s]
g = gravity = 9.81[m/s^2]
v0 = 0
![y = v_{0}*t+0.5*g*t^{2}\\ y=0.5*(9.81)*(0.75)^{2}\\y= 2.76[m]](https://tex.z-dn.net/?f=y%20%3D%20v_%7B0%7D%2At%2B0.5%2Ag%2At%5E%7B2%7D%5C%5C%20y%3D0.5%2A%289.81%29%2A%280.75%29%5E%7B2%7D%5C%5Cy%3D%202.76%5Bm%5D)
