Answer:
t = 123.59s
Explanation:
For the launch pad section:
Vf = Vo + a*t where Vo=0.
Vf = 35*25 = 875m/s
The distance traveled during the launch:
Now the projectile motion, we know that its initial speed is the speed calculated previously and the initial height is the y-component of the previously calculated distance.
where d= 10937.5m; Vo=875m/s.
Solving for t:
t1 = -11.093s t2 = 98.59s
So, the total time of flight will be:
When energetic UV rays dissociates molecules of oxygen into seperate atoms. But when they collide into each other it forms OZONE.

Answer:
Best at conductioning heat- Solid
Explanation:
<u><em>In order for heat to conduct it has to pass from particle to particle.</em></u>
A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.
A liquid has isn't as compacted it actually has enough space to slide over each other
A gas has very far apart particles and takes heat longer to transfer from one particle to another.
Answer:
Explanation:
mass m = 3 kg
spring constant be k
k x .8 = 40 N
k = 40 / .8 = 50 N /m
angular frequency ω = √ ( k / m )
= √ ( 50 / 3 )
= 4.08 rad /s
Let amplitude of oscillation be A .
1/2 k A² = 1/2 m v²
50 A² = 3 x 1²
A = .245 m = 24.5 cm
For displacement , the equation of SHM is
x = A sinωt
= 24.5 sin4.08 t
x = 24.5 sin4.08 t
Here, angle 4.08 t is in radians .
