Answer:
518400 Newton
Explanation:
Force F = mass m * Acceleration a
a = velocity v / time t
v = distance d / t
Therefore;
F = m * v² / d
with m = 2000 (unit not defined but say g)
v = 144 Km/h
d = 80 meters =0.08Km
F = 2Kg * 144Km/h * 144Km/h / 0.08Km
F = 518400 Newton
Net force = mass × acceleration
F= ma
a = F/M
a = 6f/2m
a= {3f/m} ms-²
It will possibly be A) chemical b/c it can make a sound like when the bar hits the ball it makes a sound correct?! and also it created heat especially when it hits the ball. and when the ball MOVES and the bar HITS it creates kinetic energy, but when you hit the ball it doesn’t create a new substance.
Answer:
They are inversely proportional
Explanation:
The force of gravity and the distance between two objects involved are inversely proportional to one another.
According to newton's law of universal gravitation "the force of gravity between two bodies is a product of their masses and inversely proportional to the distances between them".
- The force of gravity and distance between two bodies are inversely related.
- The larger the distance between two bodies the lesser the force of gravity between them.
Explanation:
Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation. Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
