Density equals mass × volume
d=m/V
then m=d×V=19.3×2=38.6g
m=38.6g
hope this helps you
Answer:
I think it's (C) magnitude and direction
Explanation:
scalar is only magnitude and no direction so that answer makes no since, and i would think speed can't go anywhere without direction so i think (C)
hope it's right
brainliest please
Answer:
the energy absorbed is 4.477 x 10⁶ J
Explanation:
mass of the liquid, m = 13 kg
initial temperature of the liquid, t₁ = 18 ⁰C
final temperature of the liquid, t₂ = 100 ⁰C
specific heat capacity of water, c = 4,200 J/kg⁰C
The energy absorbed is calculated as;
H = mcΔt
H = mc(t₂ - t₁)
H = 13 x 4,200(100 - 18)
H = 4.477 x 10⁶ J
Therefore, the energy absorbed is 4.477 x 10⁶ J
No becuase the simplified case of constant speed, use the formula:
<span>distance = speed x time</span>
I think the answer to your question is twenty-four percent.
