Answer:
yes
Explanation:
because it is a diverging mirror
<u>Answer</u>:
316.67 Hz
<u>Explanation</u>:
Given:
Wave velocity ( v ) = 95 m / sec
wavelength ( λ ) = 0.3 m
We have to calculate Frequency ( f ) :
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > f = v / λ
Putting values here we get:
= > f = 95 / 0.3 Hz
= > f = 950 / 3 Hz
= > f = 316.67 Hz
Hence, frequency of sound is 316.67 Hz.
Answer:
Explanation:
I = V/R = 120 V/ 50 Ω = 2.4 A
P = VI = 120(2.4) = 288 W = 288 J/s
288 J/s (15 min(60s / min)) = 259,200 J
or the electric company would charge for
288 W / (1000 W/kW)•(15/60) hr = 0.072 kW•hr
At $0.20 / kW•hr, that would be under 1½ cents
Answer:
electric potential energy
Explanation:
Electric potential energy is a energy that is needed to move a charge against an electric field. You need more energy to move a charge further in the electric field,but also more energy to move it through a stronger electric field.
Answer:
No
