A ship travels north at 15 km/h for 5 h. What is the ship's displacement in km?
2 answers:
Answer:
Displacement, d = 75 km
Explanation:
Given that :
The speed of the ship is 15 km/h. It travels for 5 h.
To find :
The displacement of the ship
Solve :
Let d is the displacement of the ship. It can be calculated using the definition of velocity. The total displacement per unit time is called the velocity of an object.
On rearranging,
d = 75 km
Therefore, the ship's displacement is 75 km.

voltage across 2.0μf capacitor is 5.32v
Given:
C1=2.0μf
C2=4.0μf
since two capacitors are in series there equivalent capacitance will be
[tex] \frac{1}{c} = \frac{1}{c1} + \frac{1}{c2} [/tex]
=1.33μf
As the capacitance of a capacitor is equal to the ratio of the stored charge to the potential difference across its plates, giving: C = Q/V, thus V = Q/C as Q is constant across all series connected capacitors, therefore the individual voltage drops across each capacitor is determined by its its capacitance value.
Q=CV
given,V=8v
charge on 2.0μf capacitor is
=5.32v

Answer:
0.25m/s
Explanation:
Given parameters
m₁ = 5kg
v₁ = 1.0m/s
m₂ = 15kg
v₂ = 0m/s
Unknown:
velocity after collision = ?
Solution:
Momentum before collision and after collision will be the same. For inelastic collision;
m₁v₁ + m₂v₂ = v(m₁ + m₂)
Insert parameters and solve for v;
5 x 1 + 15 x 0 = v (5 + 15 )
5 = 20v
v = = 0.25m/s
