the 3 resistors in parallel", but that does not do the job.
When those 3 resistors are connected in parallel, their combined resistance
is 6/11 ohm.
If the 2 and the 3 alone are in parallel, their combination is 6/5 ohms, and
adding the 1 ohm in series makes 2.2 ohms.
If the 1 and the 2 alone are in parallel, their combination is 2/3 , and adding
the 3 in series makes 3 and 2/3 .
If the 1 and the 3 alone are in parallel, their combination is 3/4 , and adding
the 2 in series makes 2.75 .
There is nothing you can do with those 3 resistors, or with any 2 of them,
or with any 1 of them, that will give you 5/6 ohm .

Answer:
causes surface currents to move in circular paths
Explanation:
Coriolis force is a pseudo force that acts on an object which is in motion in a rotating frame of reference. The Coriolis effect causes the winds to move in circular path due to rotation of Earth. In Northern hemisphere, the surface currents rotate counterclockwise and in southern hemisphere, the currents rotate clockwise.
The average time to travel just between 0.25m and 0.50m is_____
Given the time taken to travel the second 0.25m section, the velocity would be____m/s
Answers
1. Average time for the first 0.25 m: 2.23 s
Explanation:
The average time that it takes for the car to travel the first 0.25 m is given by the average of the first three measures, so:
2. Average time to travel between 0.25 m and 0.50 m: 0.90 s
Explanation:
First of all, we need to calculate the time the car takes to travel between 0.25 m and 0.50 m for each trial:
t1 = 3.16 s - 2.24 s = 0.92 s
t2 = 3.08 s - 2.21 s = 0.87 s
t3 = 3.15 s - 2.23 s = 0.92 s
So, the average time is
3. Velocity in the second 0.25 m section: 0.28 m/s
Explanation:
The average velocity in the second 0.25 m section is equal to the ratio between the distance covered (0.25 m) and the average time taken (0.90 s):
Answer:
1. 2.23
2. 0.90
3. 0.28

Given the data from the question, the bullet's temperature increases by 85.5 °C
How to determine the kinetic energy
- Mass (m) = 5 g = 5 / 1000 = 0.005 g
- Velocity (v) = 210 m/s
- Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 0.005 × 210²
KE = 110.25 J
How to determine the increase in temperature
- Kinetic energy (KE) = 110.25 J
- Heat (Q) = ½KE = ½ × 110.25 = 55.125 J
- Mass (M) = 5 g
- Specific heat capacity of lead (C) = 0.129 J/gºC
- Change in temperature (ΔT) =?
Q = MCΔT
Divide both side by MC
ΔT = Q / MC
ΔT = 55.125 / (5 × 0.129)
ΔT = 85.5 °C
Thus, the temperature increase is 85.5 °C
Learn more about heat transfer:
So KE=1/2 0.005 kg * 210m/s^2 = 110 J.
Now the specific heat capacity of lead is 126 J/kgK, so the temperature change= 55 J / 0.005 * 126 J/kgK=87.3015873 K. Which, if normal thermal conditions, the bullet would have a temperature of around 360,451587 Kelvin or, simplified, 107.3 degrees celsius.
