Answer:
Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).

Answer: 600 kg-m/s
Explanation:
Momentum = mass x velocity
momentum of spaceship 1 = 200 x 2
= 400 kg-m/s
momentum of spaceship 2 = 200 x 2
= 200 kg-m/s
Their combine momentum = 400 + 200 = 600 kg-m/s

Answer: <em>I = </em>Δ(N*B*A) / R*Δt
and
<em>I= ΔФ </em>/ <em>R*Δt</em>
Explanation:
what is electromagnetic induction?
electromagnetic induction is a mechanism where current is induced in a coil or loop. To be specific Faraday's law of electromagnetic induction says that induced EMF is proportional to the induced current or emf.
FORMULA
<em>I= ΔФ </em>/ <em>R*Δt</em>
<em>BY EXPANDING THE FORMULA WE GET</em>
<em>ΔФ= </em>Δ(N*B*A)
by putting the value in equation we get:
<em>I = </em>Δ(N*B*A) / R*Δt
where A is area of circular coil π*r²
DATA
N is number of turns in the coil
r is radius of the circular coil
ΔB is magnetic field
Δt is time
R is resistance of coil
