Answer:

a. The current is induced when there is ____3. EITHER DECREASING OR INCREASING___ magnetic flux through a closed loop of wire.

b. If the magnetic flux was constant then there _______WILL BE NO___ induced current regardless of the magnetic flux value.

c. If the magnetic flux was not constant then there __WILL BE______ induced current regardless of the magnetic flux value.

Explanation:

THIS IS BECAUSE IF FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION WHICH STATES THAT WHENEVER THERE IS A CHANGE IN MAGNETIC LINES OF FORCE LINKED WITH A CLOSED CIRCUIT AN EMF IS INDUCED

steve took a train 30 miles north to seattle then he took a different train 25 miles east draw a vector diagram showing steves t

Fed [463]

A = distance traveled by steve in north direction by train = 30 miles

B = distance traveled by steve in east direction by train = 25 miles

R = resultant displacement of the steve relative to starting position

using pythagorean theorem

R = √(A² + B²)

inserting the values

R = √(30² + 25²)

R = 39.05 miles

direction : tan⁻¹(B/A) = tan⁻¹(25/30) = 39.8 deg east of north

(BRAINLIEST W/ WORK SHOWN!!!) Help with Physics question?

VashaNatasha [74]

Answer:

$\boxed {3.43 x 10^{3}}$

Explanation:

We know that speed is defined as distance moved per unit time hence expressed as $v=\frac {d}{t}$ where v is speed in m/s, d is distance in m and t is time in seconds. Making d the subject of the above formula then

$d=vt$

Substituting 343 m/s for d and 10 s for t then

$d= 343\times10= 3430= 3.43 x 10^{3}$

Therefore, the distance between speaker and deter is $\boxed {3.43 x 10^{3}}$
