Answer: C is the correct answer
Explanation:
Answer:
7.4m/s
Explanation:
a=(v-u)/t
v= final velocity
u= initial velocity
note: when a body starts from rest,initial velocity,u=o
a= 18.5-0/2.5
a=7.4m/s
Noble Gases (He, Ne, Ar, Kr, Xe, Rn) don't form compounds because they're nonreactive as they have full valence shells (the outermost electron shell).
Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion
Answer:
340 meters
Explanation:
For this we have to use the formula of constant velocity motion:
Because you hear the blows exactly 1 per second. And you hear only one blow after she finished, the sound takes one second to get to you.
