Pressure is the force applied perpendicular to a surface divided by the area of the surface. Therefore, from the given values, we can easily calculate the area by dividing the force to the pressure. We do as follows:
Area = F / P
Area = 15000 / 190000
Area = 0.0789 m^2
Hope this answers the question. Have a nice day.
Friction would inhibit your speed and maximum work potential so, friction is the answer.
Hope this helps, Brainliest please.
C. Because they are in the same group, so they have the same number of valence (outer) electrons
Answer:
383.6 nJ
Explanation:
The energy stored in a capacitor is given by the formula:

where
C is the capacitance
V is the voltage applied
In this problem, we have
C = 14.8 nF is the capacitance of the capacitor
V = 7.2 V is the voltage
Substituting into the equation, we find:

Explanation:
The energy of the system before the collision must equal the energy after the collision.
After the collision the bullet and the block have a total mass of 18.41 kg and they move at a speed of 8.8 m/s. The kinetic energy after the collision is

Before the collision only the bullet has kinetic energy.
So we can now determine the speed of the bullet using
