The five planets that you can see from Earth without a telescope are Mercury, Venus, Mars, Jupiter and Saturn.
Answer:
Explanation:
Given that,
Two resistor has resistance in the ratio 2:3
Then,
R1 : R2 = 2:3
R1 / R2 =⅔
3 •R1 = 2• R2
Let R2 = R
Then,
R1 = ⅔R2 = 2/3 R
So, if the resistor are connected in series
Let know the current that will flow in the circuit
Series connection will have a equivalent resistance of
Req = R1 + R2
Req = R + ⅔ R = 5/3 R
Req = 5R / 3
Let a voltage V be connect across then, the current that flows can be calculated using ohms law
V = iR
I = V/Req
I = V / (5R /3)
I = 3V / 5R
This the current that flows in the two resistors since the same current flows in series connection
Now, using ohms law again to calculated voltage in each resistor
V= iR
For R1 = ⅔R
V1 =i•R1
V1 = 3V / 5R × 2R / 3
V1 = 3V × 2R / 5R × 3
V1 = 2V / 5
For R2 = R
V2 = i•R2
V2 = 3V / 5R × R
V2 = 3V × R / 5R
V2 = 3V / 5
Then,
Ratio of voltage 1 to voltage 2
V1 : V2 = V1 / V2 = 2V / 5 ÷ 3V / 5
V1 : V2 = 2V / 5 × 5 / 3V.
V1 : V2 =2 / 3
V1:V2 = 2:3
The ratio of their voltages is also 2:3

Answer:
The distance traveled will be 156.0 m
Explanation:
Please, see the attached figure 1 for a description of the problem.
The distance traveled by the prey is the magnitude of the vector "r" (see figure).
If the components of "r" are "rx" (horizontal component) and "ry" (vertical component), its magnitude will be:
We already know the vertical component of r, ry, because the prey falls from an altitude of 156 m (see figure). Then ry = 156 m
To find the value of rx we will use the function that describes the trajectory of the prey (see figure 2):
y = -39 · x² + 156
When the prey hits the ground, the height is 0 (y = 0). rx will be the value of x for which y = 0.
0 = -39 · x² + 156
-156/-39 = x²
x = 2.0 m
Then r = (2.0 m, -156.0 m)
The distance traveled will be:
