A sample of ice at 0°C has a mass of 23 g and a volume of 25 cm^3. Why does ice float on water? The density of water is 1 g.

Answer: ice float in water due to density differences. Water has a higher density than ice.less dense object in liquid with high density

Explanation: from density formulae.

D=M/V

Density of ice =Mass of ice/Volume of ice

D=23/25

D=0.92g/cm^3

A battleship that is 6.00×107kg and is originally at rest fires a 1100-kg artillery shell horizontally with a velocity of 575 m/
mel-nik [20]

Answer:

Part a)

v = 0.0105 m/s

Part b)

E = 1.82 \times 10^8 J

Explanation:

As per momentum conservation we know that

P_1 = P_2

P_1 = m_1 v_1

P_2 = m_2v_2

here we know

m_1 = 6.00 \times 10^7 kg

v_1 =  ?

m_2 = 1100 kg

v_2 = 575 m/s

Part a)

now from above expression we can say

m_1v_1 = m_2v_2

(6.00 \times 10^7)(v) = (1100)(575)

v = 0.0105 m/s

Part b)

Now increase in the internal energy of the system

E = \frac{1}{2}m_1v_1^2 + \frac{1}{2}m_2v_2^2

E = \frac{1}{2}(6.00 \times 10^7)(0.0105)^2 + \frac{1}{2}(1100)(575^2)

E = 1.82 \times 10^8 J

A stone is dropped from the roof of a high building. a second stone is dropped 1.50 s later. how far apart are the stones when t
Aleksandr [31]

2nd stone time = 13.0/9.8 = 1.33 seconds

distance = 0.5*9.8*1.33^2 = 8.67 meters

1st stone time = 1.33+1.5 = 2.83 seconds

distance = 0.5*9.8*2.83^2 = 39.24 meters

39.24-8.67 = 30.57 meters apart
