Answer:
160,000 N
Explanation:
Given:
m = 320,000 kg
v₀ = 0 m/s
a = constant
t = 57 s
Δx = 810 m
Find: Fnet
Apply Newton's second law:
∑F = ma
Fnet = ma
To find Fnet, we must first find the acceleration.
x = x₀ + v₀ t + ½ at²
810 m = 0 m + (0 m/s) (57 s) + ½ a (57 s)²
a = 0.50 m/s²
Fnet = (320,000 kg) (0.50 m/s²)
Fnet = 160,000 N
Answer:
B. 0.1 meters/second/second in the same direction of travel.
Explanation:
Acceleration is the rate of change of velocity. Acceleration is a vector quantity.
a=Δv/Δt
=(v₂-v₁)/(t₂-t₁)
v₁=4 m/s
v₂=6 m/s
t₁=0 s
t₂=20 s
a=(6m/s-4m/s)/(20s-0)
= 0.1 m/s² in the same direction of travel.
Therefore acceleration =0.1 meters/second/second in the same direction of travel.

steamAnswer: (d) particles of steam at a hundred degrees CelsiusThe highest kinetic energy will be in particles of steam at a hundred degrees Celsius.
Answer:
Sound travels in air as a series of compressions and rarefactions. When an object vibrates it will move back and forth. As it moves forth, it pushes adjacent air particles. ... This is a compression: an area of high pressure that moves along the direction of the sound wave.
Explanation:
adjacent is the answer
