Answer:
The Magnitude of the angle of reflection equals that of Incidence from the Law of reflection
So its 50°.
Explanation:
A baryon is a particle consisting of three quarks or three antiquarks.
In order to form a neutral baryon (such as the neutron, which has electric charge zero), we must have two quarks with charge
(down, strange or bottom quark), and one quark with charge
(up, charm or top quark), so that the total charge will be zero:
A second possibility is to have a neutral baryon consisting of three antiquarks, of which two of them have charges
(anti-down, anti-strange or anti-bottom), and one of them has charge
(anti-up, anti-charm or anti-top), so that the total charge is still zero:
Answer:
70 mph
Explanation:
We can write the position of the car at time t as
where is the speed of the car, while the position of the truck is
where
is the initial distance between the car and the truck (at 3:00 pm)
is the speed of the truck
The car overcomes the truck when they have same position, so
This occurs at 4:30 pm, so 1:30 h (1.5 h) after the initial instant. So, by using
t = 1.5 h
And solving the equation for , we find the speed of the car:
Answer:
L = 16 [in]
Explanation:
In order to find the arch we must first find the angle that forms the circular sector, using the following formula:
Now using the following equation we can calculate the arc length
