The non-relativistic formula for low speed v < 0.1c is:
K.E = 0.5mv^2 = 0.5 * 235 * (7)^2 = 5757.5 J
I believe this would be an example of positive acceleration as the initial velocity of the rocket is less than the final velocity, indicating that the rocket is accelerating and thus is positive.
Answer: A) O N
Explanation:
An object in motion will maintain its state of motion. The presence of an unbalanced force changes the velocity of the object.
3.0 typically is only felt by people who are resting or on the up stairs of buildings. 6.0 is more intense. I would say a 6.0 can produce high intensity levels. A 6.0 can damage buildings of good design and structure. Damagable in poorly built or badly designed structures. Some chimneys may be broken.
Answer:
Explanation:
The formula for linear expansivity, 
original length, l₁ = 123 cm = 1.23 m
final length, l₁ = 92.6 cm =0.926 m
original temperature, θ₁ = 200°C
Linear expansivity, α = 2 * 10⁻⁵ °C⁻¹
Putting these values into the formula:
