A ray of light is incident on a plane mirror at an angle of 30 degree state the angle of reflection?​
kozerog [31]

Answer:

30°

Explanation:

<em>The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.</em>

∠i = ∠r

so as ∠i = 30°

∠r will also be 30°

A 1250 kg car is stopped at a traffic light. A 3550 kg truck moving at 8.33 m/s hits the car from behind. If bumpers lock, how f
Radda [10]

Answer:

the two vehicles will be moving at a speed of 6.16  m/s

Explanation:

This is a case of completely inelastic collision, therefore, the conservation of momentum can be written as:

m_1\,v_1+m_2\,v_2=(m_1+m_2)\,v_f

which given the information provided results into:

m_1\,v_1+m_2\,v_2=(m_1+m_2)\,v_f\\(1250)\,(0)+(3550)\,(8.33)=(1250+3550)\,v_f\\29571.5=4800\,v_f\\v_f=6.16\,\,m/s

Can you please explain me how to do integration in physics in a easy way?
d1i1m1o1n [39]
The easiest way to explain it is roughly identical to the way that your teacher explained it in class.  If there were any easier way ... like writing it here in a few paragraphs ... then that's what the teacher would have done.  You would have been given the easy explanation on the first day of class, printed on one sheet of paper, and you would have had the rest of the year to practice it and get really good at it.
If the class spent a month teaching it, then that's about how long it takes.  Sorry.
