The 4 states of matter are solid, gas liquid, and plasma.
New substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide. Hopefully this will help you decide...
Answer:
50%
Explanation:
Given parameters:
Work output = 30J
Work input = 60J
Unknown:
Efficiency of the lever = ?
Solution:
To solve this problem, the efficiency is taken as the ratio of the work output to that of the work input;
Efficiency = Work output / Work input x 100
Efficiency = x 100 = 50%
Answer:
Explanation:
When the suitcase is being released, it has a horizontal velocity of v0, a vertical velocity of 0 and vertical acceleration of g
The time it takes for it to drop by the vertical distance of α under acceleration g can be solved using the following equation of motion
This is also the time it takes for the suitcase to travel horizontally at the rate of v0. So the horizontal distance it travels is
