Specific gravity = Density of an object/Density of water


Density = Mass/Volume


For the current scenario;


Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3


Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

Specific gravity = Density of an object/Density of water

Density = Mass/Volume

For the current scenario;

Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3

Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

Therefore,
Specific density of halite = 2.164 g/cm^3 / 1 g/cm^3 = 2.164

vodka [1.7K]

Answer:

The canon B hits the ground fast.

Explanation:

Given that,

Speed of cannon A = 85 m/s

Speed of cannon B= 100 m/s

Speed of cannon C = 75 m/s

We need to calculate the cannonballs will hit the ground with the greatest speed

Using conservation of energy

The final kinetic energy of canon depends on initial kinetic energy and potential energy.

The  final velocity depends upon initial velocity and initial height.

So,  the initial velocity of canon B is high.

Hence, The canon B hits the ground fast.

Answer:

R=3818Km

Explanation:

Take a look at the picture. Point A is when you start the stopwatch. Then you stand, the planet rotates an angle α and you are standing at point B.

Since you travel 2π radians in 24H, the angle can be calculated as:

\alpha =\frac{2*\pi *t}{24H}  t being expressed in hours.

\alpha =\frac{2*\pi *11.9s*1H/3600s}{24H}=0.000865rad

From the triangle formed by A,B and the center of the planet, we know that:

cos(\alpha )=\frac{r}{r+H}  Solving for r, we get:

r=\frac{H*cos(\alpha) }{1-cos(\alpha) } =3818Km
