Answer:
3 x 10^ 8 m/s
Explanation:
Speed of wave = wavelength/time period
= 30000/0.0001
= 300000000 m/s
Hi there!
The maximum deformation of the bumper will occur when the car is temporarily at rest after the collision. We can use the work-energy theorem to solve.
Initially, we only have kinetic energy:
KE = Kinetic Energy (J)
m = mass (1060 kg)
v = velocity (14.6 m/s)
Once the car is at rest and the bumper is deformed to the maximum, we only have spring-potential energy:
k = Spring Constant (1.14 × 10⁷ N/m)
x = compressed distance of bumper (? m)
Since energy is conserved:
We can simplify and solve for 'x'.
Plug in the givens and solve.
Explanation:
Using Coulomb's law, the relation between force and charge is as follows.
F =
In the given case, = q
Hence,
F =
Squaring on both the sides, we get
q =
=
= C
=
Thus, we can conclude that magnitude of the charge on each grape is .
