The working equation to be used for this is written below:
E = kQ/d²
where
E is the electric field
k is a constant equal to 8.99 x 10⁹ N m²/C²
Q is the charge
d is the distance
E = (8.99 x 10⁹ N m²/C²)(17×10⁻⁹ C)/(0.05 m)²
E = 61,132 N/C
Answer:
The answer is C either the frequency or the wave lenght of the light
Explanation:
The frequency determins the brightnes of a color and the wave lenght determines the spectrum
The final temperature of the mixture is closest to 32.5 °C
<h3>Data obtained from the question</h3>
- Mass of warm water (Mᵥᵥ) = 50 g
- Temperature warm water (Tᵥᵥ) = 40 °C
- Mass of cold water (M꜀) = 30 g
- Temperature of cold water (T꜀) = 20 °C
- Specific heat capacity of the water = 4.184 J/gºC
- Equilibrium temperature (Tₑ) =?
<h3>How to determine the equilibrium temperature </h3>
Heat loss = Heat gain
MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – M꜀)
50 × 4.184 (40 – Tₑ) = 30 × 4.184(Tₑ – 20)
209.2(40 – Tₑ) = 125.52(Tₑ – 20)
Clear bracket
8368 – 209.2Tₑ = 125.52Tₑ – 2510.4
Collect like terms
8368 + 2510.4 = 125.52Tₑ + 209.2Tₑ
10878.4 = 334.72Tₑ
Divide both side by 334.72
Tₑ = 10878.4 / 334.72
Tₑ = 32.5 °C

Answer:
force is 96 N
Explanation:
given data
mass = 40 kg
acceleration = 2.4 m/s²
to find out
force
solution
we know force is mass time acceleration so
we will apply here force formula that is express as
force = m × a ..............1
here m is mass and a is acceleration so
put here value in equation 1 we get force
force = 40 × 2.4
force = 96
so force will be 96 N
1. V= 110
I= 11
R=10
2. V= 110
I= 5.5
R= 20
3. V= 100
I= 5
R= 20
4. V= 500
I= 5
R= 100
To show work plug in those numbers to V=IR
