The result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴. Details about exponential functions can be found below.
<h3>How to calculate multiplication involving exponentiation?</h3>
Exponentiation is the process of calculating a power by multiplying together a number of equal factors, where the exponent specifies the number of factors to multiply.
According to this question, the following exponential function is given:
9 × 10-⁵ ÷ 3 × 10-⁹
9/3 × 10-⁵+⁹
3 × 10⁴
Therefore, the result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴.

Answer:
a) 51.8 m, b) 27.4 m/s, c) 142 m
Explanation:
Given:
v₀ = 42.0 m/s
θ = 60.0°
t = 5.50 s
Find:
h, v, and H
a) y = y₀ + v₀ᵧ t + ½ gt²
0 = h + (42.0 sin 60.0) (5.50) + ½ (-9.8) (5.50)²
h = 51.8 m
b) vᵧ = gt + v₀ᵧ
vᵧ = (-9.8)(5.5) + (42.0 sin 60.0)
vᵧ = -17.5 m/s
vₓ = 42.0 cos 60.0
vₓ = 21.0 m/s
v² = vₓ² + vᵧ²
v = 27.4 m/s
c) vᵧ² = v₀ᵧ² + 2g(y - y₀)
0² = (42.0)² + 2(-9.8)(H - 51.8)
H = 142 m

Answer:
9.2 m/s
Explanation:
v^2 = u^2 + 2as
u = 4.71
a= g * sin(8.30)
v= sqrt( 4.71^2 + 2 * 9.8* sin( 8.30 deg) * 22) = 9.2 m/s
Answer:
Explanation:
15 ) Current_rms = Peak current / √2
= 6 / √2
= 4.24 A
Voltage_rms = 4.1 / √2
= 2.9 v
Average power = Voltage_rms x Current_rms
= 2.9 x 4.24
= 12.3 W
16 ) R₂ = 2R₁
Resistance of a material changes due to change in resistivity of material .
So resistivity ρ₂ will also be twice resistivity ρ₁
ρ₂ = 2ρ₁
2ρ₁ = ρ₁ ( 1 + .0035 t ) where t is rise in temperature.
1 = .0035 t
t = 1 / .0035
= 285.7 ⁰ C
