<span>The metal that  would absorb the MOST heat is Copper. </span>Copper is used in heat sink because it has many advantageous properties for thermally effective and long lasting heat converters..Copper is an excellent conductor of heat. It's high thermal conductivity allows heat to pass through it quickly. <span>Aluminium heat sinks are used as a cheaper, lightweight substitue to copper heat sinks, but they have a lower thermal conductivity than copper.</span>

A 1.00 -kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Fig. P8.62a). The object has
LekaFEV [45]

The distance D where the object comes to rest is 1.08.m.

<h3>What is the distance?</h3>
  • The separation of one thing from another in space; the distance or separation in space between two objects, points, lines, etc.; remoteness. The distance of seven miles cannot be accomplished in one hour of walking.
  • Learn how to use the Pythagorean theorem to get the separation between two points using the distance formula. The Pythagorean theorem can be rewritten as d==(((x 2-x 1)2+(y 2-y 1)2)
  • The distance between any two places is the length of the line segment separating them. By measuring the length of the line segment that connects the two points in coordinate geometry, the distance between them may be calculated.

(c) the distance D where the object comes to rest.

W_{total} =ΔKE ⇒ -0.25*1*9.8*D = 0-1/2*1*2.3^{2}

⇒D=\frac{0.5*2.3^{2} }{2.45}

⇒1.08.m

How to feel in this chart
xeze [42]
You can find them in a chart but the atomic mass unit (amu) is defined as the proton mass.  Proton = 1amu, neutron =1 amu, electron = 0.005amu
charge on P is +1, charge on N is 0, and charge on electron is -1

Please answer ASAP .
Arisa [49]

Answer:

Explanation:

a = gsinθ

a = 9.8sin30

a = 4.9 m/s²

v² = u² + 2as

v² = 0² + 2(4.9)(10)

v² = 98

v = √98 = 9.8994949...

v = 9.9 m/s
