Answer:
a) 0.99999 e
b) 1*10^-5 s
c) 3*10^-2 m
Explanation:
Given data:
Electron energy : 50 GeV
assuming the rest mass of an electron = 0.5 MeV/c^2
A) Determine the velocity of each electron
velocity of each electron ( v ) ≈ 0.999 e
B) How much time does it take the electrons to travel the length of the accelerator given that the accelerator = 3km long
Lo = 3 * 10^3 m
T = (3 * 10^3 )/ (0.999 * 3 * 10^8)
= 1 * 10 ^-5
C) How long does the accelerator look form the perspective of the electrons
L = Lo / r = Lo
hence L = 3 * 10^-2 m
Answer:
The weight of the person would increase
Explanation:
The Universal Law of Gravitation gives the magnitude of the force between the masses of two objects (m1 and m2) separated a given distance "d" as:
where G is the universal gravitational constant.
Our weight on Earth is this force between the Earth (of mass M) and ourselves (our mass m) at a distance that is the Earth's radius R:
Now, if we keep all the values equal (mass of the Earth M and our mass m) except for the distance between the center of the Earth and our center of gravity (the radius of the Earth), we are going to have now a smaller radius (r) in the formula above:
and dividing by a smaller number (r is smaller than R), will render a larger quotient. This means that the actual force (weight) will become larger, so the weight would clearly increase.
Answer:
432 units
Explanation:
Let the charges be q and Q separated by a distance r. The electrostatic force , F = kqQ/r² = 72 units. If q = 2q and Q = 3Q, then the new electrostatic force is
F = k × 2q × 3Q/r² = 6kqQ/r² = 6 × 72 = 432 units
Answer:
6.28 m/s.
Explanation:
Given that,
The mass of the object, m = 0.2 kg
The radius of the circle, r = 0.5 m
It takes the object 0.500 s to complete one revolution.
We need to find the translational speed of the object. Let it is v. We know that,
So, the transalational speed of the object is 6.28 m/s.
Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
