That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:

Answer:Third</h2>
Explanation:
Newton's third law states that every action force has a equal and opposite reaction force.
Example 1:
Consider yourself hitting a wall with your hand,you are exerting a force on the wall but still you feel hurt because the wall exerts same force on your hand in opposite reaction.
Example 2:
Consider yourself standing on ground.You are exerting force on ground.But how are you able to stand on ground even if your mass is forcing you to go down?The answer is normal reaction force.The ground exerts a force on your feet which makes you to stand still.
Answer:
Wavelength can always be found by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

Answer:
Explanation:
heat lost by block of copper
= mass x specific heat x fall in temperature
= .04 x 385 x ( 95 - 24 )
= 1093.4 J
Heat gained by water
= .105 x 4200 x ( 24 - T ) ; Here T is initial temperature of water .
= 441 ( 24 - T )
heat lost = heat gained
1093.4 = 441 ( 24 - T )
24 - T = 2.48
T = 21.52 ℃
