Answer:
3.122×10¹⁴ g/cm³
Explanation:
Diameter of neutron star = 23 km = 2300000 cm
Radius of neutron star = 2300000/2 = 1150000 cm = r
Mass of neutron star = 1.989 × 10³⁰ kg = 1.989 × 10³³ g = m
Volume of neutron star
Density = Mass / Volume
∴ Density of neutron star is 3.122×10¹⁴ g/cm³
Answer:
Explanation:
From the given information:
We know that the thin spherical shell is on a uniform surface which implies that both the inside and outside the charge of the sphere are equal, Then
The volume charge distribution relates to the radial direction at r = R
∴
To find the constant k, we examine the total charge Q which is:
∴
Thus;
Hence, from equation (1), if k =
To verify the units:
↓ ↓ ↓
c/m³ c/m³ × 1/m
Thus, the units are verified.
The integrated charge Q
since
The answer is:
A) Light wave changes direction.
Here is why:
In refraction, the<u> light bends or changes direction</u> when it passes through one medium to another. The change happens because the speed of light is different depending on the medium it passes through because the density of the medium is different.
Another difference would be the angle of incidence. In reflection the angle of incidence is equal to the angle of reflection but in refraction, they are not the same.
Kinetic energy is equal to 0.5 times m v squared. Now you use that and substitute and you'll get the kinetic energy in joules.
1. If Maggie gives her cat an unfair advantage, her experimental results will be biased.
Explanation:
Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.
- Due to her emotional attachment with the cat, the experimental results will be skewed to portraying her cat as intelligence.
- This is not a good experiment to carry out.
- Such an experiment should be carried out with an unknown cat.
