Answer:

The charge is 0.056 nC.

Explanation:

Given that,

Electric field = 2000 N/C

Distance = 5.0 cm

We need to calculate the charge density

Using formula of charge density

E=\dfrac{\lambda}{2\pi\times\epsilon_{0}r}

\lambda=2\pi\times\epsilon_{0}\times r\times E

Put the value into the formula

\lambda=2\pi\times8.85\times10^{-12}\times5.0\times10^{-2}\times2000

\lambda=5.56\times10^{-9}\ C/m

We need to calculate the charge in 1.0 cm

Using formula of charge

Charge = \lambda\times\text{length of segment}

Charge =5.56\times10^{-9}\times1.0\times10^{-2}

Charge=0.056\times10^{-9}\ C

Charge=0.056\ nC

Hence, The charge is 0.056 nC.

A cannonball is fired perfectly horizontally from the top of a 210 m tall cliff. It is fired with an initial velocity of 50 m/s.
pochemuha

Answer:

the horizontal distance covered by the cannonball before it hits the ground is 327.5 m

Explanation:

Given;

height of the cliff, h = 210 m

initial horizontal velocity of the cannonball, Ux = 50 m/s

initial vertical velocity of the cannonball, Uy = 0

The time for the cannonball to reach the ground is calculated as;

h = u_yt - \frac{1}{2} gt^2\\\\h = 0 - \frac{1}{2} gt^2\\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 210}{9.8} }\\\\t  = 6.55 \ s

The horizontal distance covered by the cannonball before it hits the ground is calculated as;

X = U_x \times \ t\\\\X = 50 \times \ 6.55\\\\X = 327.5 \ m

Therefore, the horizontal distance covered by the cannonball before it hits the ground is 327.5 m

Which BEST describes the physical properties of the Earth’s core?
Sonja [21]

C) a solid lower part and a liquid upper part

Explanation:

The physical nature of the earth's core is made up of a solid lower part and a liquid upper part.

The core is the innermost part of the earth and it is made up of metallic minerals.

  • It has the highest temperature and pressure of all the layers of the earth.
  • The core is divided into two. Outer and inner core.
  • Outer core is made up of molten metallic minerals. It is the layer where the earth geomagnetic field originates.
  • The inner core is solid metallic ball.
  • Evidence from seismic waves has furnished geoscientists with this knowledge.
