Answer:
That the mass can not be created or destroyed in a chemical reaction
Explanation:
Answer:
c
Explanation:
When a satellite is orbiting the earth , a constant force is being applied on it which means it must has acceleration. Also the direction of satellite is always being changed when it is orbitting to there is always change in the velocity vector which means acceleration.
You can view in the attached diagram to understand how the velocity is being changed.
Recall that
<em>v</em>² - <em>u</em>² = 2 <em>a</em> ∆<em>x</em>
where <em>u</em> and <em>v</em> are initial and final velocities, respectively; <em>a</em> is acceleration; and ∆<em>x</em> is the distance traveled (because the skater moves in only one direction).
So we have
(5.8 m/s)² - (8.8 m/s)² = 2 <em>a</em> (6.0 m)
<em>a</em> = ((5.8 m/s)² - (8.8 m/s)²) / (12 m)
<em>a</em> = -3.65 m/s²
Explanation:
Convert the time to seconds : 5minutes × 60 = 300seconds
Acceleration = Velocity / Time
Acceleration = 20m/s / 300s
Acceleration = 0.067m/s²
Distance = Velocity × Time
Distance = 20m/s × 300seconds
Distance = 6000m
