Answer:
Trial 1: 2 Volts, 0 %
Trial 2: 2.8 Volts, 0%
Trial 3: 4 Volts, 0 %
Explanation:
Th experimental values are given in the table, while the theoretical value can be found by using Ohm/s Law:
V = IR
<u>TRIAL 1</u>:
V = IR
V = (0.1 A)(20 Ω)
<u>V = 2 volts</u>
% Difference = x 100%
% Difference = |(2 - 2)/2| x 100%
<u>% Difference = 0 %</u>
<u>TRIAL 2</u>:
V = IR
V = (0.14 A)(20 Ω)
<u>V = 2.8 volts</u>
% Difference = x 100%
% Difference = |(2.8 - 2.8)/2.8| x 100%
<u>% Difference = 0 %</u>
<u></u>
<u>TRIAL 3</u>:
V = IR
V = (0.2 A)(20 Ω)
<u>V = 4 volts</u>
% Difference = x 100%
% Difference = |(4 - 4)/4| x 100%
<u>% Difference = 0 %</u>
It is easy to see the think layers in the stone. Metamorphic rock often forms layers due to being squeezed under pressure. Since it separates into think sheets,slate has been used for chalkboards roof,shingles,and pool table tops.
Hello!!
For calculate the Velocity of the wave let's applicate the formula:
V = Velocity = ?
f = Frequency = 300 Hz

Answer:
Angle θ ≅ 21.5°
Explanation:
Given:
speed Vi= 60 m/s, Range R= 250 m, g=9.81 m/s²
To find:
Angle θ = ?
Sol: we know that Rang R = Vi² sin 2θ / g
⇒ Sin 2θ = g×R / Vi²
Sin 2θ = (9.81 m/s² × 250 m) / ( 60 m/s)²
Sin 2θ = 0.68125
2θ = Sin ⁻¹ (0.68125)
2θ = 42.9413
θ = 42.9413 / 2
θ = 21.4706 ≅ 21.5°
Answer:
