Answer:

E = 0.93 10⁻⁶ N/C, 24º NorthEast

Explanation:

The electric force is related to the electric field by the relation

          F = q E

where the bold letters indicate vectors and q is a scalar electric charge.

Using this equation the electric force is in the same direction as the electric field.

The magnitude of the field is

          E = F / q

the charge they give us is q = 8.7 C

let's calculate

          E = 8.1 10⁻⁶ / 8.7

          E = 0.93 10⁻⁶ N / C

In summary, the magnitude of the electric field is E = 0.93 10⁻⁶ N/C and its direction is 24º NorthEast

Hi there!

We know that:

U (Potential energy) = mgh

We are given the potential energy, so we can rearrange to solve for h (height):

U/mg = h

g = 9.81 m/s²

m = 30 g ⇒ 0.03 kg

0.062/(0.03 · 9.81) = 0.211 m

An object is thrown directly upwards from the ground at a velocity of 9ms. Recalling that the acceleration due to gravity is −gm
olga55 [171]

Answer:

Explanation:

Given

Object is thrown with a velocity of u=9\ m/s

Acceleration due to gravity is -g (i.e. acting downward)

Vertical distance traveled by object is given by

v^2-u^2=2as  

where v=final velocity

u=initial velocity

a=acceleration

s=displacement

at maximum height final velocity is zero

0-(9)^2=2\times (-g)\times (s)

s=\frac{81}{2g}=\frac{40.5}{g}\ m

time taken to reach maximum height

using

v=u+at

0=9-gt

t=\frac{9}{g}\ s

Jeff puts on a leather jacket over his sweater. The sweater becomes negatively charged. Which statements about Jeff’s situation
KiRa [710]

The sweater has a tendency to attract electrons.

The leather jacket has a lower tendency to attract electrons than the sweater.

Explanation:

The sweater and the leather jackets are made up of distinct fabrics that based on their minutest particles called an atom.

An atom is made up of sub-atomic particles of protons, neutrons and electrons.

  • Electrons occupies the bulk volume of the atom and they are easily lost in atoms that are big. They are negatively charged.
  • Protons are positively charged and are very difficult to lose. They occupy the tiny nucleus with neutrons.
  • A body that becomes negatively charged will be said to have a hihg tendency to attract electrons. Normally atoms are electrically neutral. When additional electrons are added to them, they become negatively charged.
  • In this case, the sweater has a high affinity for electrons and it will attract the ones on the leather jacket.
  • The leather jacket has a low tendency to attract electrons than the sweater and it will lose some of its electrons to the sweater.

Answer:

Hi myself Shrushtee.

Explanation:

The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.
