Wave A has a higher amplitude than Wave B.
Explanation:
please check the attached image for the waves
Answer:
F = 960 N
Explanation:
given,
acceleration = 2 m/s²
Force = 450 N
mass = 255 Kg
to calculate the force propelling the bobsled forward
∑ F = ma
F - f = ma
F = m a + f
F = 255 × 2 + 450
F = 510 + 450
F = 960 N
the magnitude of the force propelling the bobsled forward is F = 960 N
Distance covered= 65-25= 40 Km
Time Taken = 0.5 hour
Speed= 40/0.5= 80 km/hr
Answer:
The charge of each charge is 
Explanation:
When yo have two charged particles they interact exerting an electrostatic force in the other particles, the magnitude of the electrostatic force between two particles is:
(1)
with q1 and q2 the charges, r the distance between them and k the Coulomb's constant (
)
Because the charges we're dealing are identical positive q1=q2, then (1) is:

Using the values the problem give us:

solving for q:
