Answer: The elimination of seasonal variations
Explanation:
Since the cosmic catastrophic event which occurred led to the tilt of the Earth's axis relative to the plane of orbit to increase from 23.5° to 90°, the most obvious effect of this change would be the elimination of seasonal variations.
It should be noted that seasonal variation refers to the variation in a time series that's within a year which is repeated. The cause of seasonal variation can include rainfall, temperature, etc.
Answer:
The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor
Explanation:
The impedance of an LCR circuit shown as
Z = √R² + (X↓l - X↓c)²
Z = √R² + (2π∨L - 1/2π∨c)²
Variation of Z with respect to υ is shown in the figure.
As υ increases, Z decreases and so the current increases.
At υ = υ↓r
Z is minimum, current is maximum. Beyond
υ = υ↓r
Z increases and so current decreases.
so the combination of circuit elements that is most suitable to comprise
the circuit is R, L and C.

Answer:
The Flemings left hand rule is used to find the magnitude of a magnetic force
Explanation:
Fleming's left hand rule states that if the first three fingers are held mutually at right angles to one another, then the fore finger points into the direction of magnetic field the middle finger in the direction of current while the thumb points in the direction of force.
Mathematically
Magnetic Force F= BILsinθ
Where
B= magnetic field density Tesla
I= current
L= length of conductor
θ= angle of conductor with field
Answer:
P = 1 x 10⁸ Pa
Explanation:
given,
radius = 2.0 ×10⁻¹⁰ m
Temperature
T = 300 K
Volume of gas molecule =
V = 33.51 x 10⁻³⁰ m³
we know,
P V = 1 . k T
k = 1.38 x 10⁻²³ J/K
P(33.51 x 10⁻³⁰) = 1 . (1.38 x 10⁻²³) x 300
P = 1.235 x 10⁸ Pa
for 1 significant figure
P = 1 x 10⁸ Pa
D. The man's traits (ff) would be recessive and with one of the girls (FF), all their offspring would have the genotype Ff, meaning all the offspring have freckles.
