Answer:

1.71km

Explanation

Velocity is defined as the change in displacement of a body with respect to time. Displacement specifies direction and as such is a vector quantity.

Mathematically;

Velocity = displacement/time

Displacement = velocity ×time

Given velocity of the body = 0.95m/s

Time = 30minutes

Time = (30×60)seconds

= 1800seconds

Displacement = 0.95×1800

Displacement = 1710m

Since 1000m = 1km

1710m to km will give;

1710/1000

= 1.71km

Answer:

1.71 km

Explanation:

Convert 30 minutes to seconds:

30 min × (60 s / min) = 1800 s

Find the displacement:

0.95 m/s × 1800 s = 1710 m

Convert to kilometers:

1710 m × (1 km / 1000 m) = 1.71 km

I NEED ANSWER ASAP
umka21 [38]

Answer:

97% will sink below the water

Explanation:

Waters density is 1 g/cm3

If an object's density is greater than 1g/cm3, it will sink. If it's less then it would float. 1-0.97 = 0.03. Only 3% of the ice would show while 97 will be under.
