Answer: circulatory

respiratory

muscular

Explanation:

The physical fitness can be define as the state of well being and health. It indicates towards the ability of the organisms to perform various aspects of physical activities such as sports, daily routine work, and occupational tasks. It is achieved by moderate to vigorous physical exercises, sufficient amount of rests and proper nutrition.

The physical fitness involves the proper functioning of the vital systems of the body these includes the respiratory, circulatory and muscular. As the body performs exercise it requires more amount of oxygen also the muscles performing activity deprive of the oxygen, the rate of respiration increases, more amount of blood is pumped out by the heart to fulfill the need of oxygen.

calculate the density of a neutron star with a radius 1.05 x10^4 m, assuming the mass is distributed uniformly. Treat the neutro

Orlov [11]

To develop this problem it is necessary to apply the concepts related to the proportion of a neutron star referring to the sun and density as a function of mass and volume.

Mathematically it can be expressed as

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

Where

m = Mass (Neutron at this case)

V = Volume

The mass of the neutron star is 1.4times to that of the mass of the sun

The volume of a sphere is determined by the equation

$V = \frac{4}{3}\pi R^3$

Replacing at the equation we have that

$\rho = \frac{1.4m_{sun}}{\frac{4}{3}\pi R^3}$

$\rho = \frac{1.4(1.989*10^{30})}{\frac{4}{3}\pi (1.05*10^4)^3}$

$\rho = 5.75*10^{17}kg/m^3$

Therefore the density of a neutron star is $5.75*10^{17}kg/m^3$

An electric generator converts kinetic energy into which kind of energy?

dem82 [27]

Answer:

Electrical Energy

Explanation:

An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. ... Because the coil is rotating in a magnetic field, electric current is generated in the wire.

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 690.0 kg and was tra

butalik [34]

Answer:

The speed of car A before collision is 3.5 km/h.

Explanation:

Mass of car A = 690 kg eastwards

Mass of car B = 520 kg at 74 km/h west wards

Distance, s = 6 m

coefficient of friction = 0.75

Let the speed after collision is v.

Use third equation of motion

$v^2 = u^2 + 2 as \\\\0 =v^2- 2 \times 0.75\times9.8\times 6\\\\v = 9.4 m/s = 33.84 km/h$

Let the initial speed of car A is v'.

Use conservation of momentum

690 x v' - 520 x 74 = (690 + 520) x 33.8

690 v' + 38480 = 40898

v' = 3.5 km/h
