Answer:
Acceleration will be 
Explanation:
We have given speed of the moving object u = 11 cm /sec
As the object move from +2.79 x -coordinate to -5 x- coordinate
So total distance = 5+2.79 = 7.79 cm
Time is given as t = 2.55 sec
We have to find the acceleration
From second equation of motion we know that 
Answer:
e). The ratio is not given
Explanation:
<u>Capacitance of a capacitor</u>
The expression for the capacitance of a capacitor with di electric material is given as
C=KεA/d
where
ε=permittivity of di electric
C= capacitance in farads
A= Area of plate
d= separating distance
K= dielectric constant
let the distance in capacitor B be 1mm
therefore the distance in A is 0.5mm
For the first (A) capacitor
C1=8εA/0.5
C1=16εA
For the Second (B) capacitor
C2=8εA/1
C2=8εA
the ratio of the capacitance of A to B
=C1/C2
=16εA/8εA
=2/1
=2
<span>The Balmer series or Balmer lines in atomic physics, is the designation of one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is calculated using the Balmer formula, an empirical equation discovered by Johann Balmer in 1885. this is all I know sorry</span>
A peak = A Rms x Sq root 2
Therefore 3.6 x sq root of 2
A peak = 5.09
Explanation:
The free fall acceleration is:
F = ma
20 N = (0.50 kg) a
a = 40 m/s²
The mass of Planet X is:
F = GMm / r²
20 N = (6.67×10⁻¹¹ Nm²/kg²) M (0.50 kg) / (4.0×10⁶ m)²
M = 9.6×10²⁴ kg
