An atom has no electrical charge simply because the number of protons is equal to the number of electrons. However, if the atom gains an extra electron, it becomes negatively charged. If it loses and electron, then the atom becomes positively charged

During each heartbeat, about 80 g of blood is pumped into the aorta inapproximately 0.2 s. During this time, the blood is accele
taurus [48]

Answer:

Work is done by the heart on the blood during this time is 0.04 J

Explanation:

Given :

Mass of blood pumped, m = 80 g = 0.08 kg

Initial speed of the blood, u = 0 m/s

Final speed of the blood, v = 1 m/s

Initial kinetic energy of blood is determine by the relation:

E_{1}=\frac{1}{2} m u^{2}

Final kinetic energy of blood is determine by the relation:

E_{2}=\frac{1}{2} m v^{2}

Applying work-energy theorem,

Work done = Change in kinetic energy

W = E₂ - E₁

W=\frac{1}{2} m (v^{2}-u^{2})

Substitute the suitable values in the above equation.

W=\frac{1}{2}\times0.08\times (1^{2}-0^{2})

W = 0.04 J

The charges on the proton and electron are typically measured in: Select the correct answer below: volts amperes coulombs dalton
malfutka [58]

Answer: columbs

Explanation:

Electrical charge are measured in columbs, usually demoted as C. Hence, the charges on proton and electron will be measured in Coloumbs. It typically measures the amount of electricity conveyed per second by a current of 1 ampere. The other units Given such as ; Volt is used for measuring voltage, which is the pressure in an electrical source. AMPERE is used for measuring the current flowing through an electrical circuit.

Dalton is a unit of mass and is about 1.660 * 10^-27 kg

The upward force exerted on an object falling through air is _____.
stira [4]

(C) Air Resistance

<u>Explanation:</u>

When an object falls through air, air resistance acts on it in upward direction. When air resistance acts, acceleration during a fall will be less than g because air resistance affects the motion of the falling objects by slowing it down. Air resistance depends on two important factors - the speed of the object and its surface area. Increasing the surface area of an object decreases its speed.

Why are viruses hard to fight
ki77a [65]

Answer:Compared to other pathogens, such as bacteria, viruses are minuscule. And because they have none of the hallmarks of living things — a metabolism or the ability to reproduce on their own, for example — they are harder to target with drugs.

Over [174]

Answer:

\sqrt{ ({40}^{2} }  +  {50}^{2} ) =  \sqrt{(1600 + 2500)}  =  \sqrt{4100}  = 64.03
