Answer:
Explanation:
the variations in riser height or tread depth should not be grater than that is equal to 9.5 mm but the maximum riser height should be the 
but variation in riser height should not exceed to . The minimum riser height should be 7 inches which is equal to the 178 mm
It defines that if two thermodynamic systems are each in equilibrium with a third system, then they are in equilibrium with each other.
That's going to depend on the initial velocity, and how it changes
or doesn't change during the 2.6 seconds. I've read the question,
and Im pretty sure you didn't tell us any of that.
Answer:
Explanation:
If a rocket (firework) is launched
with an initial velocity of 39.2 meters per second at a height of 1.6 meters above
the ground, the equation h = -4.9t2
+ 39.2t + 1.6 represents the rocket’s height h in
meters after t seconds. The rocket will explode at approximately the highest point.
Fire official require the fireworks to explode at a height greater than 76 feet in
order for debris to land in Lake Michigan and not on the festival sight. The event
planners assured the fire officials that the fireworks would reach a height greater
than 76 feet
