The two situations are similar because in both you are trying to minimize the damage and make the best out of a bad situation
Answer:
1.99×10^-4coulombs
Explanation:
The charge (Q) across the resistor the directly proportional to the voltage (V) where capacitance of the capacitor(C) is the proportionality constant. Mathematically, Q = CV
If V is the voltage across the resistor, V = IR (according to ohm's law) where I is the current in the resistor and R is the resistance.
We need to calculate the voltage on the resistor first when 0.18A current is passed through it.
V = 0.18 × 185
V = 33.3Volts
The charge Q on the resistor will be;
Q = CV
Were C = 6.00 μF, V = 33.3
Q= 6×10^-6 ×33.3
Q = 0.0001998
Q= 1.99×10^-4Coulombs

Below is an attachment containing the solution
Answer:
Perfectly inelastic collision
Explanation:
There are two types of collision.
1. Elastic collision : When the momentum of the system and the kinetic energy of the system is conserved, the collision is said to be elastic. For example, the collision of two atoms or molecules are considered to be elastic collision.
2. Inelastic collision: When the momentum the system is conserved but the kinetic energy is not conserved, the collision is said to be inelastic. For example, collision of a ball with the mud.
For a perfectly elastic collision, the two bodies stick together after collision.
Here, the meteorite collide with the Mars and buried inside it, the collision is said to be perfectly inelastic. here the kinetic energy of a body lost completely during the collision.
The Energy is Kinetic Energy.
Kinetic Energy = 1/2*mv², Where m is mass in kg, v is velocity in m/s
Energy is 33750 Juoles, v = 30m/s
1/2*mv² = E
1/2*m*30² = 33750
m = (2*33750) / (30²) Using a calculator
m = 75 kg
Mass of object is 75 kg.
