Answer:
i believe the answer is B only because i looked it up on g00gle so take what i say with a GRAIN of salt all puns intended
Explanation:
Answer:
The circuit is in series connection,
the same current will flow through i.e
I1 = I2 = I3 = 2A.
Explanation:
We'll begin by calculating the total resistance in the circuit. This is shown below:
R1 = 4Ω
R2 = 3Ω
RT =..?
Total resistance in series can be obtained as follow:
RT = R1 + R2
RT = 4 + 3
RT = 7Ω
Next we shall determine the total current flowing in the circuit:
Voltage (V) = 14V
Resistance (R) = 7Ω
Current (I) =..?
V = IR
14 = I x 7
Divide both side by 7
I = 14/7
I = 2A.
Since the circuit is in series connection,
the same current will flow through i.e
I1 = I2 = I3 = 2A.
Answer:
Transverse waves
Explanation:
Transverse waves are a type of wave that oscillates perpendicular to the direction of movement (the direction of propagation). These type of waves are usually represented by the sine or cosine functions due to the up and down oscillation of the waves.
In the case of water waves the thing that oscillates up and down are the <u>water particles</u> affected by the disturbance.
And for the case light waves what oscillates are the <u>electric and magnetic fields</u>, both oscillating perpendicular to the direction of light propagation.
Answer:
The percent error in his estimation is 30%
Explanation:
Percentage error = |UA- UE| \ UE × 100
UA= Actual value = 7 pounds
UE = Expected value = 10 pounds
Percent error of his estimate = ∣7-10∣ / 10 ×100
= ∣-3∣ / 10 × 100
= 30%
Answer:
True; ar = v^2 / R Radial acceleration because it moves in a circular path
at = α R = tangential acceleration because its speed changes
a = at + ar total acceleration equals sum of radial and tangential
