Yes it is, in other simplified terms density compares the amount of matter an object has to its volume.
Given data
*The given force is F = 583 N
*The given distance is s = 1.5 m
*The given time is t = 2.1 s
The formula for the power it takes for a 583 N student to climb up 1.5 m stairs in 2.1 seconds is given as
Substitute the known values in the above expression as
Hence, the power it takes for a 583 N student to climb up 1.5 m stairs in 2.1 seconds is P = 416.42 W

Answer:
W = 53.6648 J
Explanation:
W = ∫ F * dr
F = < 4*x i , 3*y j > Newtons
dr = < dx, 0 >
Take the dot product:
F * dr = 4* x * dx
Now replacing numeric
W = ∫ 4 * x * dx , ║ x = ( 0 m ⇒ 5.18 m )
W = ¹ / ₂ * (4 N/m) * x ²
W = (2 N/m) * (5.18 m)²
W = 53.6648 J
Answer:
177.213 grams
Explanation:
Given:
Total amount of water = 364 grams
Latent heat of fusion = 333 kJ/kg
Heat transferred = 62.2 kJ
The amount of water frozen = 62.2/333 = 0.186786 kg = 186.786 grams
Hence, the amount of water remained unfrozen = Total water - Amount of water frozen
the amount of water remained unfrozen = 364 grams - 186.786 grams = 177.213 grams
