Answer:
V = S / t speed of wave
V = 2 * 180 m / 1 sec = 360 m/s speed of sound wave
Answer:
a)H=84.87 m
b)R=565.27 m
Explanation:
Given that
Speed of ball on earth
U=41.2 m/s
θ=31°
We know that
Maximum height in projectile motion given as


h=22.94 m
Range in projectile motion given as


r=152.77 m
Given that on distance planet ball moves 3.7 times far more as on earth.
So on the distance planet
The maximum height ,H=3.7 h
H= 3.7 x 22.94
H=84.87 m
The range on distance planet
R=3.7 r
R=3.7 x 152.77 m
R=565.27 m
The correct answer should be D. copper
Nickel, cobalt, and iron, produce magnetic fields when electrified while copper does not.
Answer:
It depends on the climate and wind speed at the time.
If the climate is hot and no breeze it will move slower.
If it is cold and very windy it will move rapidly.
Answer:
Answer: B. Explanation: For an object to accelerate the force on it must be increased. According to Newton's second law of motion.
