The density of seawater is 1.025 g/ml. what is the mass of 1000 liters of seawater in g amd kg?

Answers

Answer 1

Answer: You are giventhe density of seawater which is 1.025 grams per milliliters and its volume at1000 liters. You are required to find the mass of the seawater in grams andkilograms. You need to know that density is equal to mass over volume. Let usdenote D as our density, V our volume and M as our mass. So,

D = M/V
M = D*V
M = (1.025g/mL)(1000 L)(1000mL/1L)
M =1,025,000 g
To changeinto kilograms, simply divide it by 1000
M = (1,025,000g)(1kg/1000g) = 1,025kg

Answers

Answer:

v = 24 m

Explanation:

Given that,

The x component of the vector = 12 m

The y component of the vector = 21 m

We need to find the magnitude of a vector. It can be solved as follows :

$v=√(12^2+21^2) \n\n=24.18\ m$

v = 24 m

So, the magnitude of the vector is equal to 24 m.
