i can <u>when do u need it by</u> working on it now!!!
The maximum speed of Tim is 16.95 m/s.
The given parameters:
- Mass of the rope, m = 71 kg
- Tension on the rope, T = 220 N
- Coefficient of kinetic friction, = 0.1
- Time of motion, t = 8 s
<h3>What is Newton's second law of motion?</h3>
- Newton's second law of motion states that, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The net force on Tim is calculated by applying Newton's second law of motion as follows;

Thus, the maximum speed of Tim is 16.95 m/s.

Answer:
0.05
Explanation:
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.
<h2>
Option A is the correct answer.</h2>
Explanation:
A 10-ω resistor and a 30-ω resistor are connected in series across a 100-V battery
Total resistance = 10 + 30 = 40 ω
We have
Voltage = Current x resistance
100 = I x 40
I = 2.5 A
In series current in all the resistors are same, that is 2.5 A
Voltage in 10ω resistor, V = I x 10 = 2.5 x 10 = 25 V
In parallel connection potential in all the resistors are same.
Voltage in 10ω resistor, V = 100 V
The ratio of the potential difference across the 10-ω resistor in the series combination to that of the 10-ω resistance connected in parallel = 25/100 = 1/4
Option A is the correct answer.
