Answer:
Rectilinear propagation describes the tendency of electromagnetic waves to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.
The loudness or sound intensity of the roaring truck engine is inversely proportional to the square of the distance. it follows the law of squares that is
r1^2 / r2^2 = L2/L1
8^2 / 4^2 = L2 / 100 dB
L2 = 400 dB
The answer to this problem is 400 dB increased frim 100 dB.
Don’t quite know what answer you’re looking for since I can think off couple straight off the bat. But the best answer I can think of is maybe Kinetic energy? If that sounds wrong then sorry, I don’t quite know what it is you’re learning about
Answer:
Net force = 25N and in the right direction
Explanation:
mass of box, m = 50kg
Force of block = 150N
Friction force = 125N
150 - 125 = 25N
the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
I think its likely to explode
