B) moves with a constant speed until hitting the other end.
Answer: mmm... If you mean most like Basketball it's net ball but i don't know much about Basket ball teams
Explanation:
Answer:
=30.22°C
Explanation:
The enthalpy change made the water to cool.
Enthalpy change = MC∅ where M is the mass of the water, C is the specific heat capacity of water and ∅ the temperature change.
ΔH=MC∅
∅=ΔH/MC
=(6.3×10⁴J)/(0.5kg×4186J/(kg°C))
=30.1
Final temperature = 35.00°C-30.1°C
=4.9°C
Explanation:
An object is attached to the spring and then released. It begins to oscillate. If it is displaced a distance 0.125 m from its equilibrium position and released with zero initial speed. The amplitude of a wave is the maximum displacement of the particle. So, its amplitude is 0.125 m.
After 0.800 seconds, its displacement is found to be a distance 0.125 m on the opposite side. The time period will be, 
We know that the relation between the time period and the time period is given by :


f = 0.625 Hz
So, the frequency of the object is 0.625 Hz. Hence, this is the required solution.
Explanation:
Particle moving in a circular path with a constant speed.
