Explanation:
Assuming that there is no air resistance, the given time means that the ball reached its maximum height 3 seconds after throwing it upwards so we can solve its
maximum height by solving for
first:


Now that we know
we can now solve for 



Inversely proportional to the mass of the object directly proportional to the magnitude of the net force in the same direction as the net force
Answer:
Based on color theory it would come out as brown
Explination:
Basic color theory states the primary colors are red yellow and blue. Expanding that to the rainbow you know. Red plus yellow equals orange. Yellow plus blue equals green. And blue plus red equals purple. Red and Green are opposite colors and when you combine opposite colors you get brown
Answer:
The angular speed is 0.83 rad/s.
Explanation:
Given that,
Mass of disk M=49 kg
Radius = 1.7 m
Mass of child m= 29 kg
Speed = 2.6 m/s
Suppose if the disk was initially at rest , now how fast is it rotating
We need to calculate the angular speed
Using conservation of momentum


Put the value into the formula



Hence, The angular speed is 0.83 rad/s.
Answer:
A
Explanation:
Intensity is proportional to amplitude
