Answer:
Explanation:
The system boy-skateboard can be modelled by means of the Principle of Momentum Conservation:
The final velocity of the skateboard:
The wavelength<span> in a </span>longitudinal wave<span> is probably the distance between two consecutive compressions or between two consecutive rarefactions. The amplitude is the maximum displacement from equilibrium. ... The amplitude is the distance from the equilibrium position of the medium to a compression or a rarefaction.</span>
Answer:
3600 m SOUTH
Explanation:
avg velocity= (change displacement)/(change in time)
2.0 m/s= x/ (1800 s)
displacement= (2.0 m/s * 1800s)= 3600 m SOUTH
.......
sign explanation
2.0 m/s south= -2.0 m/s (downwards direction)
-2.0 m/s= x/ (1800 s)
x= -3600 m
Answer:
95.21
Explanation:
Magnesium has a molar mass of 24.31 and CHlorina has a molar mass of 35.45. Since there are 2 Cl you add 35.45 to 35.45= 70.9. Then add the 24.31 for Magnesium. 70.9 + 24.31= 95.21.
Answer: A
it's a sign that there might be something causing too much
current to flow in the circuit
Explanation: When a fuse blows, one of the causes may be short circuit. Also, it's a sign that there might be something causing too much
current to flow in the circuit leading to overloading. That is, drawing to much of power that can cause the metal inside the fuse to melt.
Option A is the best answer.
