An 85.0 kg fisherman jumps from a dock at a speed of 4.30 m/s onto their 135.0 kg boat. If the boat was at rest to begin but mov
jeka94

Answer:

Final speed of boat + man is 1.66 m/s

Explanation:

As we know that there is no friction on the system or there is no external force on this system

So here we can use momentum conservation here

mv = (m + M)v_f

so we have

m = 85 kg

M = 135 kg

v = 4.30 m/s

now we have

85 \times 4.30 = (85 + 135) v

v = 1.66 m/s

2. What is the resistance expected on a heater that is feed by 480V AC and the Electric Power is 4.6kW? ​
Korvikt [17]

The resistance expected of the heater is 50.1 ohms.

<h3>What is resistance?</h3>

Resistance can be defined as the opposition to the flow of electric current in an electric circuit. The S.I unit of resistance is Ohms (Ω).

To calculate the resistance of the heater, we use the formula below.

<h3>Formula:</h3>
  • R = V²/P............. Equation 1

Where:

  • R = Resistance of the heater
  • P = Power of the heater
  • V =  Voltage supplied to the heater

From the question,

Given:

  • V = 480 V
  • P = 4.6 kW = 4600 W

Substitute these values into equation 1

  • R = (480²)/4600
  • R = 50.1 ohms.

Hence, the resistance expected of the heater is 50.1 ohms.

Which of the following is not a process that forms metallic ore
Kamila [148]

 

I believe that this question has the following choices to choose from:

placer deposits

fossil compaction

hydrothermal solutions

igneous processes

 

Actually among all, I have never encountered an ore that formed due to fossil compaction. I suppose we can get minerals such as marble or lime but not ores. So the answer is:

 

<span>fossil compaction                (answer)</span>
