The answer is to u question is: C
Answer: Particles cannot bend around the edges of an obstacle, as light waves does.
Explanation:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .When this occurs, the wave bends around the edges of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
Note this phenomenon is a characteristic of waves behaviour and not particles, because <u>particles cannot bend around the edges of an obstacle</u>, as waves (light waves in this case) does.
Answer:
m = 47.5 Kg
Explanation:
given,
speed of skater toward north, v = 0.8 m/s
momentum of the skater in north, P = 38 Kg.m/s
mass of the skater = ?
we now,
Momentum is equal to the product of mass and velocity
P = m x v
38 = m x 0.8
m = 47.5 Kg
hence, mass of the skater is equal to 47.5 Kg.
Answer:
0.0835 m
Explanation:
The magnetic force exerted on the deuteron is equal to the centripetal force that keeps it in circular motion:
where
is the charge
is the speed of the deuteron
is the magnetic field strength
is the mass of the deuteron
r is the radius of the orbit
re-arranging the equation, we find:
The answer is 7 electrons. We know that Carbon has 6 electrons, so we could see that there is the charge that is -1, meaning there has to be one more electron than proton because that means it's gained an electron of -1 charge. Therefore 7 electrons to 6 protons.
