Answer:
The statement is true
Explanation:
The complete question is
Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate
True or False
Solution
The given statement is true as it is the dielectric permittivity of the material which does not allow light to pass through it easily.
The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.
The ovum, plural ovae (latin) produced in the female bodies of mammals ovaries are the female sex cells.
The sperm are the male sex cells. Produced in the testes.
When sperm and ovum meet, there is a chance that they could join together and thus start a new life. Process is called fertilisation
Heat is most closely related to THERMAL energy.
It can push or pull an object.... I think.
Answer:
v=1.26 m/s
Θ=81°NE
Explanation:
Linear momentum is the product of the mass and velocity of an object.
Dog's momentum can be hold using its mass and velocity:
m=26.2kg
v=3.21 m/s
(kg⋅m/s)
same thing with the cat
m=5.30kg
v=2.64m/s
(kg⋅m/s)
owner's momentum
p =13.992 m/s i + 84.102 m/s j
divide by mass to get velocity:
v = 0.20m/s i + 1.25 m/s j
mag v = √(0.20² + 1.25²) m/s = 1.26 m/s
Θ = arctan(1.25/0.2) = 81º north of east
