Answer:
Particle-antiparticle annihilation is the result of a direct interaction between a particle and its corresponding anti particle, like a proton and an anti-proton or an electron and a positron. The result of such interaction is the production of two powerful gamma rays, each of whom has an energy roughly equal to E = mc^2, where m is the mass of the particle.
Could you scroll up a little so I can see the first part of the question- I MIGHT be able to help you then. Thanks!
Answer:
Speed, v = 7.83 m/s
Explanation:
It is given that,
Length of the bridge, l = 5 m
The road on the far side is 2.0 m lower than the road on this side, x = 2 m
The horizontal distance covered by the car is 5 meters and the vertical distance covered by the car is 2 meters.
Initial speed of the car, u = 0
Let t is the time taken by the car . Using the second equation of motion as :
For vertical distance :
Let v is the velocity to jump the stream. It is given by :
Horizontal distance, d = 5 m
v = 7.83 m/s
So, the car should travel with a speed of 7.83 m/s. Hence, this is the required solution.
Explanation:
The magnitude of the net force can be found with Pythagorean theorem.
F² = Fx² + Fy²
F² = (1.06 N)² + (9.37 N)²
F = 9.43 N
The direction can be found with trigonometry (measured from the -y axis):
θ = atan(Fx / Fy)
θ = atan(1.06 / 9.37)
θ = 6.45°
Answer:
Quantity of charge = 1800 Coulombs
Explanation:
Given the following data;
Current = 1 A
Time = 0.5 hours
Conversion:
1 hour = 60 * 60 = 3600 seconds
0.5 hour = 0.5 * 3600 = 1800 seconds
To find the charge passing through the wire;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge = current * time
Substituting into the formula, we have;
Quantity of charge = 1 * 1800
Quantity of charge = 1800 Coulombs
