Answer:
0.25 m
Explanation:
Refraction occurs when the velocity or wavelength of a wave changes at the interface between two media.
We know that refractive index=
Wavelength in medium A/wavelength in medium B = velocity in medium A/velocity in medium B
Let the wavelength of medium B be a
0.5/a = 0.3/0.15
0.5 × 0.15 = 0.3 × a
a= 0.5 × 0.15/0.3
a= 0.25 m
The situation given above is that of the geometric sequence with first term equal to 75 meters and the common ratio equal to 0.40. The sum of the terms for an infinite geometric sequence is expressed in the equation,
S = a1/(1 - r)
Substituting,
S = (75 m) / (1 - 0.4) = 125 m
Therefore, the total distance that the pendulum had swung before finally coming to rest is 125 m.
We have that Zero signifies a perfect circle shape and 1 shows it maximum out of order shape.
From the question we are told
What does it mean when the orbital eccentricity of a planet is close to 1
Generally
Eccentricity
This in its simplest definition means to be eccentric which means to be a bit out of order or for the given subject at hand means to be a bit out of shape
Naturally the Eccentricity that an object possess is defined by two number 0(zero) to 1(one)
Where
Zero signifies a perfect circle shape and 1 shows it maximum out of order shape

Answer:
the final speed of the barrier would be 40m/s
Explanation:
Hello, I think I can help you with this.
the momentum is given by:
P=m*v, where P is the momentum, m is the mass of the object and v is the speed of the object.
if the momentum is transferred completely it means that the barrier will have the same amount of momentum, in other terms
momentum of the moped=momentum of the barrier
mass of the moped*speed of the moped=*speed of the barrier
let's isolate the final speed of the barrier
final speed of the barrier is
so, the speed is 40 m/s
The correct answer is (B) The force on A is exactly equal to the force on B. Two tiny beads are 25 cm apart with no other charges or fields present. Bead A carries 10 µC of charge and bead B carries 1 µC. The statement that<span> is true about the magnitudes of the electric forces on these beads is the force on A is exactly equal to B.</span>
