Answer:
Option 2
Explanation:
The theory supported by the statement : "<u><em>Mountain ranges often appear on the edges of continents.</em></u>", is that :
- <u>Mountain ranges were formed when continents collided.</u>
Answer:
(d) a net external force must be acting on the system
Explanation:
Momentum is given as the product of mass and velocity.
P = MV
According to Newton's second law of motion, " Force applied to a body (system) is directly proportional to the rate of change of momentum of the body (system) which takes place in the direction of the applied force (external force).
F ∝ΔMV
Therefore, If the total momentum of a system is changing, a net external force must be acting on the system.
(d) a net external force must be acting on the system
Given:
length of the wire = 0.20 meters
magnetic field strength = 0.45 newtons/amperes meter
speed = 10.0 meters per second
emf = B * l * v
B = flux density ; l = length of the wire ; v = velocity of the conductor
emf = 0.45 newtons / ampere meter * 0.20 meters * 10.0 meters/seconds
emf = 0.90 volts
The emf produced is 0.90 volts.
Answer:
C
Explanation:
vectors are any quantities that have both magnitude and direction
therefore both inertia and weight are both vectors
Answer:
The same
Explanation:
Momentum is conserved before and after collision.
Hope this helps!
