Answer:
A) Does not change
B) Decrease
C) Increasing
D) Increasing
Explanation:
When it pushes it's volume is reduced by 1/3 because it's Area is constant there for only volume is decreased. Then the number of molecules don't change
A) don,t change
B) Decreases
C) Density is increased because it mass doesn't change. there for
Mass = Density * Volume
When Volume is decreasing to keep mass constant Density will be increased.
D) Pressure is increased according to the boil's law. it says that for fixed mass and fixed temperature pressure is inversely proportional to the volume. then volume decrease pressure increase
Answer:
The correct option is;
D. There is not enough information to answer this question
Explanation:
The universal gravitational constant = 6.67408 × 10⁻¹¹ 3³/(kg·s²)
For an in between distance of 1 m and equal masses of 60 kg, we have;
The gravitational attraction ≈ 2.403 × 10⁻⁷ N, which does not correspond with the answers, therefore, the best option is that there is not enough information to answer this question.
Answer:
f = 0.4 Hz
Explanation:
The frequency of rotation of an object in order to achieve required centripetal or radial acceleration, can be found out by using the following formula:
f = (1/2π)√(ac/r)
where,
f = frequency of rotation = ?
ac = radial acceleration = 34.1 m/s²
r = radius = length of beam = 5.55 m
Therefore,
f = (1/2π)√[(34.1 m/s²)/(5.55 m)]
<u>f = 0.4 Hz</u>
Answer:
After pulses pass through each other, each pulse continues along its original direction of travel, and their original amplitudes remain unchanged.
Explanation:
Constructive interference takes place when two pulses meet each other to create a larger pulse.
Answer:
Phenomena is the plural form of Phenomenon.
A phenomenon is an extraordinary occurrence or circumstance.
