Answer:
The correct answer is d.
Explanation:
The law of reflection states that an incident ray on a reflecting surface will be reflected at an angle equal to the angle of incidence, where each angle is measured concerning the line normal to the surface.
In the graph that indicates what happens when light interacts with matter and is reflected, you make the mistake of not following the law of reflection in scattering.
Have a nice day!
Answer:
F = 0.114 N
Explanation:
a) The magnetic force is given by the equations
F = q v x B = I Lx B
the bold incate vector. This equation can be used in the form of magnitude and find the direction separately with the rule of the right hand
F = i L B sin θ
Where θ is the angle between the direction (L) and the magnetic field, if the two are perpendicular sin 90 = 1
Let's calculate
F = 3.30 0.127 0.272
F = 0.114 N
b) to know the direction of the magnetized field we must know the direction of B and L, but in the problem they tell us that they are perpendicular, but not the direction of each
The mass of the ball has to be 2.36 depending on the size and width
Answer:
Part a)
a = - 8.45 m/s/s
Part b)
Part c)
Explanation:
Part a)
when car apply brakes then the friction force on the car in front of us is given as
here we need to find deceleration due to friction
Part b)
Braking distance of the car is the distance that it move till it stops
so we will have
Part c)
Since we know that average reaction time for human is 0.424 s
now we know that during reaction time our car will travel at uniform speed
so we will have
