Answer:
it should be tension for the space
Answer:
6.65×10⁻⁷ s
Explanation:
Speed of light in water = Total distance traveled in water/time
c = d/t ....................... Equation 1
Where c = speed of the light pulse in water, d = distance traveled in water, t = time.
also
c = v/n ..................... Equation 2
Where v = speed of light in air, n = refractive index of water
Substituting equation 2 into equation 1
v/n = d/t
making t the subject of the equation,
t = nd/v.................. Equation 3
Given: 150 m.
Constant: n = 1.33, v = 3.0×10⁸ m/s
Substitute into equation 3
t = 1.33(150)/3.0×10⁸
t = 6.65×10⁻⁷ seconds.
Hence the time = 6.65×10⁻⁷ s
A.) 3,800
* Add 1800+2000 because they are both going forward, and you are look for the total amount of forward force. Hope this helped good luck!!!
Answer:
heterogeneous mixture :)
Explanation:
homogenous means the same type is in it, heterogeneous means different parts.
