Answer:
a,b,c and d.
Explanation:
Of the following statements the correct are:
a) It is possible to induce a current in a closed loop of wire located in a uniform magnetic field by either increasing or decreasing the area enclosed by the loop.
b) It is possible to induce a current in a closed loop of wire without the aid of a power supply or battery.
d) It is possible to induce a current in a closed loop of wire by change the orientation of a magnetic field enclosed by the wire.
e) It is possible to induce a current in a closed loop of wire by changing the strength of a magnetic field enclosed by the wire.
It's geography,
tropical climate
For this case, the first thing you should observe is the variables:
Vertical axis: speed
Horizontal axis: time
Since the relationship between both variables is linear then we have that the slope of the line represents the acceleration according to the formula:
Where,
a: acceleration
t: time
vf: final speed
vo: initial speed
According to the equation, in the interval of 6 to 8 seconds, we observe that the slope of the Elan line is greater than the slope of the Anna line.
Therefore, for the 6 to 8 second interval, the Elan acceleration is greater.
Answer:
From 6 to 8 seconds, Elan accelerated faster than Anna.
Answer:
θ_c = 24.4º
Explanation:
To find the critical angle, let's use the law of refraction where index 1 refers to the incident medium (diamond) and index 2 refers to the medium where it is to be refracted (air)
n₁ sin θ₁ = n₂ sin θ₂
for the critical angle the ray comes out refracted parallel to the surface, therefore the angle is
θ₂ = 90
n₁ sin θ₁ = n₂
θ_c = θ₁ = sin⁻¹
the index of refraction of the diamond is tabulated
n₁ = 2.419
let's calculate
θ_c = sin⁻¹ ()
θ_c = 24.4º
