<h2>
Stopping force on the bullet is 1073.23 N to the left.</h2>
Explanation:
Mass of bullet, m = 11.0 g = 0.011 kg
Initial speed of bullet, u = 210 m/s
Final speed of bullet, v = 0 m/s
Displacement of bullet, s = 22.6 cm = 0.226 m
We have equation of motion v² = u² + 2as
Substituting
0² = 210² + 2 x a x 0.226
a = -97566.37 m/s²
We have
Force, F = Mass x Acceleration
F = 0.011 x -97566.37 = -1073.23 N
Negative means opposite to the direction of motion of bullet.
Stopping force on the bullet is 1073.23 N to the left.

Answer:
The speed with which the disk slides across the surface is 1.33095 m/s.
Explanation:
Given that,
Mass of disk = 0.14 kg
Spring constant = 155 N/m
Length = 4 cm
We need to calculate the speed
Using energy conservation
Where, k = spring constant
x = compressed length
m = mass of the disc
Put the value into the formula
Hence, The speed with which the disk slides across the surface is 1.33095 m/s.
10km/hr or 80mph is the possible answer I can give
Answer:L=109.16 m
Explanation:
Given
initial temperature
Final Temperature
mass flow rate of cold fluid
Initial Geothermal water temperature
Let final Temperature be T
mass flow rate of geothermal water
diameter of inner wall
specific heat of water
balancing energy
Heat lost by hot fluid=heat gained by cold Fluid
As heat exchanger is counter flow therefore
heat lost or gain by Fluid is equal to heat transfer in the heat exchanger
