<span>A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour. How far does the puck slide in 10 seconds ?
(36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =
(36 x 1,000 x 10 / 3,600) meters = <em>100 meters</em>
What is the puck's speed in miles per hour ?
(36 km/hr) x (0.6214 mi/km) = <em>22.37 mi/hr

Answer:
2,340,000 J
Explanation:
Work done can be described as when energy or force is applied to an object to cause displacement
Work done is measured in joules
1 Watt = 1 Joule / second
650 watts = 650 Joules / second
convert 650 joules to seconds by multiplying by 3600
650 x 3600 = 2,340,000 J
Answer:
A: Ions are attracted to each other → Electrons are transferred → An ionic compound forms. B: An ionic compound forms → Ions are attracted to each other → Electrons are transferred. C: Electrons are transferred → Ions form → Ions are attracted to each other.

Answer:
Add
Explanation:
When two forces are acting in the same direction then there magnitude are added to each other
Let the first force is and second force is and when they act in same direction then their equivalent will be equal to
When they cat in opposite direction then their equivalent will be
