Answer:
A. 3,000,000 m
B. 0.25 km
C. 10 m
D. 1,000 cm
Explanation:
no hablo español, así que solo ingrese esto en el traductor de G*ogle
A. One kilometer equals 1000 meters, so
3,000*1,000 = 3,000,000 m
B. One meter equals 0.001 kilometer, so
250*0.001 = 0.25 km
C. One centimeter equals 0.01 meter
1,000*0.01 = 10 m
D. One milimeter equals 0.1 centimer, so
10,000*0.1 = 1,000

The law of conservation of momentum tells us that momentum
is conserved, therefore total initial momentum should be equal to total final
momentum. In this case, we can expressed this mathematically as:
mA vA + mB vB = m v
where, m is the mass in kg, v is the velocity in m/s
since m is the total mass, m = mA + mB, we can write the
equation as:
mA vA + mB vB = (mA + mB) v
furthermore, car B was at a stop signal therefore vB = 0,
hence
mA vA + 0 = (mA + mB) v
1800 (vA) = (1800 + 1500) (7.1 m/s)
<span>vA = 13.02 m/s</span>
Repetition occurs when multiple sets of measurements are made during one scientific investigation. Replication occurs when a scientific investigation is <span>reproduced by another person.
