If a 20 N block experiences a force of kinetic friction of 8.0 N
shutvik [7]

The coefficient of kinetic friction (μ) between the block and the table is 0.4.

<h3>What is kinetic friction?</h3>

This sis the frictional force between an object in motion with the surface in contact.

μN = ff

where;

  • N is normal reaction due to weight of the block
  • ff is frictional force
  • μ is coefficient of friction

μ = ff/N

μ = 8/20

μ = 0.4

Thus, the coefficient of kinetic friction (μ) between the block and the table is 0.4.

20. A car battery with a 12-V emf and an internal resistance of 0.050 Ω is being charged with a current of 60 A. Note that in th
topjm [15]

Answer:

Part a)

V = 15 Volts

Part b)

P = 180 Watt

Part c)

Rate = 720 Watt

Explanation:

Part a)

When battery is in charging then the potential difference of the terminals of cell is given by

\Delta V = EMF + iR

here we know that

EMF = 12 volts

i = 60 A

r = 0.050 ohm

now we have

\Delta V = 12 + (0.050)(60) = 15 Volts

Part b)

Rate of thermal energy dissipated is the energy which is dissipating across the resistor

so here we have

P = i^2 R

P = (60^2)(0.05)

P = 180 Watt

Part c)

Rate at which Energy stored inside the cell is the rate of electrical energy that is converted into the chemical energy

Rate = EMF \times i

Rate = (12)(60)

Rate = 720 Watt

Which is a true statement regarding the law of mass balance? A.Solids, gases, and liquids have their own specific equations for
nata0808 [166]

Answer:

b. when the body converts a nutrient  to another substance, there  is no effect on mass balance.

Explanation:

The law of mass balance states that the mass stays the same in any chemical reaction, that is the reason why a nutrient in human body transforms to another substance like another substance, into muscles (that has mass), a body fluid ( that has mass) or another substance, but the total mass will keep the same, just in a different shape, nature or state.
