Answer: voltage (V)
Explanation:
Hi, in the answer the letter A (1.2 A) stands for Ampere, and the symbol next to the number 24 must be Ω 8 (Ohms)
So, applying Ohm's law:
Voltage (V) =current (I) x resistance (R)
V = I x R
Replacing with the values given;
V = 1.2 A x 24Ω
In conclusion, we can calculate the value of Voltage for the circuit.

Answer:
absorbed/taken in
Explanation:
endo means internal; within.
exo means external; from outside.
We know that P = hρg
Where:
P - pressure Pa,
h - height in meter,
ρ – would be the density in kg / m^3; and
g - acceleration due to gravity is m / s^2
p = hρg if h = 0.735 meter, ρ = 13600 kg / meter^3, g = 10 meter/ sec^2
p = 0.735*13600*10 = 99960 Pa or
P = 1 x 10^5 Pa
Now with sea water if we have to make a barometer:
ρ = 1100 kg / meter^3 (given)
P = hρg if we put the value of P calculated and the value of ρ = 1100 kg /
meter^3 given, we will
get, 1 x 10^5 = h*1100*10
therefore, h = 9.09 meter or 29.82 feet of water.

Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles
