Answer:
0.211 kg
Explanation:
specific heat capacity of copper = 385 J/Kgk
heat loss by copper = mcθ = 3.8 × (8 - 84 ) × 385 = - 111188 J
heat needed to raise the temperature of water from 0°C to 8°C
= mcθ = 1.2 kg × 4180 × ( 8 - 0) = 40128 J
111188 J - 40128 J = 71060
71060 = ml
71060 / 336000 = mass of ice where latent heat of fusion = 3.36 × 10⁵JKg⁻¹
m = 0.211 kg
Velocity means [ (speed) and (direction) ].
If you're traveling around a curve, then your direction is
always changing. So your velocity is always changing,
even if your speed isn't.
Answer:
ways to exaplined
Explanation:
Density is calculated by
dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.
increase because the heavier it is the more gravitational pull it has.
Answer:
5.74
Three significant figures
Explanation:
Distance =35.896m
Time =6.25
Speed = distance / time
= 35.896/6.25
=5.74
