Answer:

(3rd Question about the Black Widow Pulsar)

J1311 is a fast spinning neutron star, which means it emits strong beams of radiation from it's poles.

As the beam of the pulsar sweeps across the surface of the companion star, it heats it up and blows its material outward into space, thus decreasing its mass.

Describe what physical meaning is attributed to ψ 2
NNADVOKAT [17]
In quantum mechanics, \psi^2 the basic wave function has no physical meaning or significance. However, |\psi|^2 represents the probability distribution of particle in a given space.

Probability \propto |\psi|^2

So when you will put a position and a time in \psi^2 function, it will give you the probability of finding the particle at that particular position and at the given time.

Diamond has a high index of refraction at about 2.4, which helps account for its sparkle. How fast does light travel through a d
wariber [46]

Answer:

1.25 \cdot 10^8 m/s

Explanation:

The speed of light through a medium is given by:

v=\frac{c}{n}

where

c = 3 \cdot 10^8 m/s is the speed of light through vacuum

n is the index of refraction of the material

In this case, diamond has a refractive index of n = 2.4, so the speed of light in diamond is

v=\frac{3\cdot 10^8 m/s}{2.4}=1.25\cdot 10^8 m/s

4. Bobby places a firecracker in plastic monster truck . The firecracker explodes sending a 0.75 kg piece of the car forward at
emmainna [20.7K]

Answer:

m₂ = 1.2 [kg]

Explanation:

Since the explosion causes a force in a certain instant of time, for both bodies there is an equal impulse. In such a way that we can relate both impulses to be able to find the mass of the body needed in the next equation.

m_{1}*v_{1}=m_{2}*v_{2}

where:

m₁ = mass of the first piece = 0.75 [kg]

v₁ = velocity of the first piece = 7.2 [m/s]

m₂ = mass of the second piece [kg]

v₂ = velocity of the second piece = 4.5 [m/s]

0.75*7.2=m_{2}*4.5\\m_{2}=1.2[kg]
