Answer:
the matter is made into paper
Explanation:
Answer:
The longer the half-life, the more stable the nucleus is.
Explanation:
Well, you know that nuclear half-life represents the time needed for an initial sample of a radioactive substance to be halved. If this is the case, a long half-life would imply that it takes a very long time for the nuclide to decay to half of its initial mass. This of cource means that it is very stable.
hope this helped c; if it did give me the brainlist please c;
The number of neutrons does an atom of tungsten (W) has is
110 neutrons
<u><em> Explanation</em></u>
Atomic mass of tungsten = total number of protons and neutrons in a nucleus of tungsten.
Therefore the neutrons of tungsten = Atomic mass of tungsten- protons of tungsten
Atomic mass of tungsten = 183.84
Tungsten protons = 74
Tungsten neutron is therefore= 183.84 - 74 = 109.84 which is approximate
110 neutrons
Answer:
50 m/s opposite direction to the motion of the truck
Explanation:
From the question,
Applying the law of conservation of momentum
mu+m'u' = V(m+m')...….. Equation 1
Where m = mass of the truck, u = initial velocity of the truck, m' = mass of the car, u' = initial velocity of the car, V = Final velocity after collision
Given: m = 2500 kg, u = 20 m/s, m' = 1000 kg, V = 0 m/s (both car stop after collision)
Substitute these values into equation 1
2500(20)+1000(u') = 0(2500+1000)
2500(20)+1000(u') = 0
Solve for u'
u' = -[2500(20)]/1000
u' = -50 m/s
The negative sign shows that the car travels in opposite direction to the truck
Hence the car initial velocity before collision is 50 m/s in opposite direction to the motion of the truck
_dThe radius of curvature of a subatomic particle under a magnetic field is given by the following formula:
Where:
We can determine the quotient between the velocity and the charge of the deuteron particle from the formula. First, we divide both sides by the mass:
Now, we multiply both sides by the magnetic field "B":
Since the charge of the deuterion is the same as the charge of the proton and the velocity we are considering are the same this means that the quotient between velocity and charge is the same for both particles. Therefore, we can apply the formula for the radius again, this time for the proton:
And substitute the quotient between velocity and charge:
Now, we cancel out the magnetic field:
Now, we substitute the values:
Solving the operations:
Therefore, the radius is 19.3 cm.
