Complete question:

It is measured that 3/4 of a body's volume is submerged in oil of density 800kg/m³. What is the specific gravity of oil?

Answer:

The specific gravity of the oil is 0.8.

Explanation:

Given;

density of the oil, $\rho_o$ = 800 kg/m³

density of water, $\rho_w$ = 1000 kg/m³

The specific gravity of any substance is the ratio of the substance density to the density of water.

Specific gravity of the oil = density of the oil / density of water

Specific gravity of the oil = 800/1000

Specific gravity of the oil = 0.8

Therefore, the specific gravity of the oil is 0.8.

True

Explanation:

In order to apply and experience the beauty of mathematics, a good comprehension of the discipline is required.

In fact, this is general to anything in life. To fully maximize any potential, one must be well groomed about what exactly that thing is.

Mathematics is a science that deals with the logic of shapes and numbers. There are different branches of this discipline with real world adoption.

The tenets of mathematics cuts across business, science, arts, e.t.c.

Mama L [17]

Answer:

$\large \boxed{\mathrm{C. \ \ \frac{500}{7 \times 15 \times 8} \ g/cm^3 }}$

Explanation:

$\displaystyle \sf Density = \frac{mass}{volume}$

$\displaystyle \rho = \frac{m}{V}$

$\sf mass=500 \ g$

$\sf volume \ of \ a \ cuboid=width \times length \times height=( 7 \times 15 \times 8) \ cm^3$

$\displaystyle \rho = \frac{500}{7 \times 15 \times 8}$

Phantasy [73]

Answer:

It will cause kinetic energy to increase.

Explanation:

Given that Speed and Motion you went from the starting line to the finish line at different rates.

If you repeated the activity while carrying weights but keeping your times the same, the weight carried will add up to the mass of the body.

And since Kinetic energy K.E = 1/2mv^2

Increase in the mass of the body will definitely make the kinetic energy of the body to increase.

Since the time is the same, that means the speed V is the same.

Weight W = mg

m = W/g

The new kinetic energy will be:

K.E = 1/2(M + m)v^2

This means that there will be increase in kinetic energy.
