Answer:
b. The rate at which charge flows
Explanation:
First we must complete the question:
Which of the following describes the measure of current:
a. The quality of the charge flow
b.The rate at which charge flows
c. The ability for something to have a charge flow
d.The potential for a charge to flow
The answer is b) The rate at which charge flows
The electric current is the electric charge flow that passes through a conductive material for a certain period of time. It is expressed in C / s, culombios per second in the international system of units, and the unit is known as Ampere (a)
The charge can be defined by culombio [C]
The equation for determining the kinetic energy of the system is,
KE = 0.5mv²
where m is the mass, v is velocity and KE is the kinetic energy. When both objects have the same mass, and velocity but different direction, they will have the same kinetic energy.
This is because the exponent in the velocity is squared cancelling out the effect of the sign appearing before the number.
The answer 1 is
The best-known use of radio waves is for communication; television, cellphones and radios all receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves that can be heard.Electromagnetic radiation is transmitted inwaves or particles at different wavelengths and frequencies.
the answer 2 is
Radio Waves: Instant Communication
Microwaves: Data and Heat
i think the answer number 3 is
It is all about wavelength versus tunnel diameter. The wavelength of GPS is about 20cm it would happily propagate in any normal tunnel if it could get in but the earth and other structures absorb it. AM radio (600kHz - 1500kHz) cannot propagate in any normal tunnel because the wavelength is too long (500m-200m) relative to the diameter, and thus gets reflected at the entrance. FM (100MHz ~ 3m) would propagate and it does for a while but then it suffers reflections
Answer:
<h3>The answer is 1200 kg</h3>
Explanation:
The mass of an object can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>1200 kg</h3>
Hope this helps you
