Answer:
F = 9.675Hz
Explanation:
pls for certain reasons let us make
- wavelength = $
- frequency = F
- V = velocity
3 loops : 6$/4 = L
6$/4 = 2
$ = 4/3 = 1.333
V = F x $
F = V/$
F = 12.9/1.333 = 9.675Hz
F = 9.675Hz
Answer:
4km/hr
Explanation:
There are 60 minute in an hour. If you divided 60 by 30 minutes you’d get 2. 2x 2km is 4km and 30x 2 is 60/an hour
F=1/(4*pi*e0)*q1*q2/r^2
e0 ≈ 8,854187817·10^−12
F=1/(4*pi* 8,854*10^(-12))*2*10^(-7)*2*10^(-7)/(0,3)^2 H = <span>

Answer:
Impulse will be 8.4788 kgm/sec
Explanation:
We have given mass of the ball m = 0.212 kg
Initial velocity u = 18.8 m/sec
We know that momentum P = mass×velocity
Taking initial velocity as negative
So initial momentum = 0.212×-18.8 = -3.9856 kgm/sec
Final velocity is given as v = 21.2 m/sec
So final momentum = 0.212×21.2 = 4.4944 kgm/sec
We know that impulse is given by change in momentum
So impulse = final momentum-initial momentum = 4.4944-(-3.9844 ) = 8.4788 kgm/sec
Answer:
Everything in the Universe is made up of matter and energy. Matter is anything that has mass and occupies space. ... Energy is the ability to cause change or do work. Some forms of energy include light, heat, chemical, nuclear, electrical energy and mechanical energy.
