Answer:
the frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
where f is the frequency
v iss the linear speed
l is the wavelength
f = ( 345 m/s ) / ( 4.38 mm ) ( 1 m / 1000 mm )
f = 78767 per second
Explanation:

Answer:
2.5 m/s²
Explanation:
You can solve the following equation: F=ma for acceleration.
You'll be left with this:
a=F/m
And then you substitute the force and the doubled mass
a=500N/200kg
a=2.5 m/s²
Answer:
A) electron
Explanation:
Matter consists of atoms. Each atom consists of three particles:
- The proton: the protons are located inside the nucleus of the atom. They have a mass of , and they have positive electric charge (). Protons are not fundamental particles, but they actually consists of three quarks (which are instead fundamental particles), in particular of 2 up quarks and 1 down quark.
- The neutron: neutrons are also located inside the nucleus. They have no electric charge, and their mass is similar to that of the proton (slightly larger). Neutrons consist of three quarks as well, in particular of 2 down quarks and 1 up quark.
- The electron: electrons are located outside the nucleus. They have a mass much smaller than protons (about ) and they have a negative electric charge, opposite to that of the proton (). The electron is a fundamental particle.
Therefore, the subatomic particle having a negative charge is
A) electron
Answer:
Cause and effect, problem and solution, order of importance, comparison and contrast.
Explanation:
We're going to remedy it with the parallelogram law.
= one hundred eighty - 30 - 70 = eighty degrees
R = sqrt(2^2 + 3^2 - 2(2)(three) cos(80)
R = three.30 kN, we can conclude now that the value of the ensuing of R is 3.30 kN
sin
/3 = sin(eighty)/three.304 = 63.4 stages
3.3 kN
180 + 33.4 = 213.4 degrees
63.4 - 30 = 33.4
