anastassius [24]

Answer: 3.48g

Explanation:

here, we will be using conservation of momentum to solve the problem. i.e the total momentum remains unchanged, unless an external force acts on the system. We'll in thus question, there is no external force acting in the system.

Remember, momentum = mass * velocity, then

mass of blood * velocity of blood = combined mass of subject and pallet * velocity of subject and pallet

Velocity of blood = 56.5cm = 0.565m

mass of blood * 0.565 = 54kg * (0.000063/0.160)

mass of blood * 0.565 = 54 * 0.00039375

mass of blood * 0.565 = 0.001969

mass of blood = 0.00348kg

Thus, the mass of blood that leaves the heart is 3.48g

Lana71 [14]

Answer:

sin 30° = \frac{v_{y} }{25}

Multiply each side by 25 to cancel the 25 under v_{y}

(25)· sin 30° = v_{y}

Multiply everything on the left side.

12.5 \frac{m}{s} = vertical velocity component.

What is the voltage measured with a voltmeter across a wire in a circuit?
Law Incorporation [45]
<h3><u>Answer;</u></h3>

<em>The voltage is zero</em>

<h3><u>Explanation;</u></h3>
  • <em><u>Voltage is the potential difference between two points in a circuit or the electromotive force in a given circuit and is expressed in volts (V). </u></em>
  • Voltage is measured by a device called voltmeter that is always connected in parallel with the current source.
  • <em><u>When voltage is measured between two points on a wire in a circuit with zero or no resistance in between the two points then the voltage will be zero</u></em><em>. </em>From the ohm's Law, voltage is given the product of resistance and current and thus if the resistance is zero then the voltage will be zero.
