For every reaction, there is an equal and opposite reaction. This means that with every interaction, theres a pair of opposite forces on the object.
Technology can be the four things listed below...
- Phones
- Computers
- TVs
- Playstation or Xbox
Answer: 4.9 g/cm^3
Explanation.
!) Data
mass = 49 g
Volume = 10 cm^3
2) Formula
Density = mass / volume
Density = 49 g / 10cm^3 = 4.9 g/cm^3
This is a problem where you only need to know the formula and subtitute the numbers to calculate.
The formula of density is the very same definition: mass per unit of volume.
So, as you had the mass and the volume you just need to plug the values in the formula density = mass / volume.
Answer:
3.528×10² V.
Explanation:
potential difference: This is the work done when one coulomb of charge moves from one point to another in an electric field. The S.I unit of potential difference is volt. The formula of potential difference is given as,
V = kq/r..................... Equation 1
And
E = kq/r² .................. Equation 2
Comparing equation 1 and equation 2,
V = E×r............................. Equation 3
Where V = potential difference, E = Electric field between the plate of the capacitor, r = distance between the plate.
Given: E = 6.3×10⁵ V/m, r = 0.56 mm = 0.00056 m.
Substitute into equation 3,
V = 6.3×10⁵×0.00056
V = 3.528×10² V.
Hence the potential difference of the plate = 3.528×10² V.
The answer to that would be a magnitude of 5
