Answer:
Collision force will be same in both the cases.
Explanation:
A perfectly inelastic collision is said to take place when a system loses the amount of its Kinetic Energy at its maximum. In a perfectly inelastic collision, the colliding particles stick to each other. In such a collision, kinetic energy is lost by combining the two bodies with each other.
In situation 1:
Speed of Car A,
Speed of Car B,
Relative speed of car A and car B,
Now, in the situation 2:
Speed of car A,
Speed of car B,
Relative speed of car A and car B,
Therefore, Car A and Car B both have the same relative speed, v = 10 m/s
Answer:
5.25%
Explanation:
From the question given above, the following data were obtained:
Accepted value = 238857 miles
Measured value = 226316 miles
Percentage error =.?
Next, we shall determine the absolute error. This can be obtained as follow:
Accepted value = 238857 miles
Measured value = 226316 miles
Absolute Error =?
Absolute Error = |Measured – Accepted|
Absolute Error = |226316 – 238857|
Absolute Error = 12541
Finally, we shall determine the percentage error. This can be obtained as follow:
Accepted value = 238857 miles
Absolute Error = 12541
Percentage error =.?
Percentage error = absolute error / accepted value × 100
Percentage error
= 12541 / 238857 × 100
= 1254100 / 238857
= 5.25%
Therefore, the percentage error is 5.25%.
Answer:
All of the choices are correct except the nodes, which don't move at all.
Explanation:
when a horizontal string fixed at both ends is oscillating in a standing wave pattern the antinodes move with simple harmonic motion while the node is stationary.
This is a poorly written question.
<span>Out of the choices listed, the first one is the only one that includes
a true statement ... the greater the mass of two objects, the
greater
the gravitational attraction is between them.</span>
-- Newton's law of universal gravitation doesn't "suggest" that. It states it ...
boldly and unequivocally.
-- The law doesn't refer to the "greatness" of the mass of the two objects.
It refers to the product of their masses.
-- It's true that the law of universal gravitation can be massaged and
manipulated to reveal the existence of gravitational planetary orbits.
But there's a lot more to it than simply the masses.
For example ... the gravitational force between two objects is inversely
proportional to
(the distance between the objects)² .
It turns out that IF that exponent were not precisely, exactly 2.000000... ,
then gravitational orbits could not exist.
