A conducting strip of width 1.5 mm is in a magnetic field. As a result, there is a potential difference of 4.3 mV across the wid
OLga [1]

To solve this problem we will apply the concepts related to the Voltage depending on the Electric field and the distance where it is applied. The relationship of this relationship is given in the following form:

V= Ed \rightarrow E = \frac{V}{d}

Here,

E = Electric Field

V = Voltage

d = Distance

Our values are given as,

d = 1.5mm = 1.5*10^{-3} m

V = 4.3 mV

V = 4.3*10^{-3}V

Replacing at the first equation we have,

E = \frac{4.3*10^{-3}}{1.5*10^{-3}}

E = 2.866V/m

Therefore the electric field in the strip is 2.866V/m

As a photon from the Sun's core interacts with an atom or ion, the photon gives up its energy to the particle. But the excited p
Natalka [10]

Answer:

Radiative transport

Explanation:

Radiative transportation takes place extensively in the core of the sun. It produces solar energy which are emitted outward from the core of the sun, and it comprises more than 70% of the sun's heat energy. At the core of the sun, the process of nuclear fusion takes where the hydrogen atoms combines with one another, and forms helium, and during this process, it releases a large amount of energy. The photons continuously interacts with the ions (or atoms) and releases this energy to the particles and the excited particles converts the excess amount of energy into another photon which are carried outward by the process of radiative transport.

A rubber band slingshot is drawn back 0.15 m with a force of 28N and shoots 28 g stone the initial speed of the stone if the rub
maria [59]

Answer:

Initial speed of stone = 12.25 m/s

Explanation:

Given:

Change in distance = 0.15 m

Force applied = 28 N

Find:

Initial speed of stone

Computation:

Using conservation of energy

(1/2)fs² = (1/2)(mv²)

fs² = (mv²)

(28)(0.15)² = (0.028)(v²)

v² = (28)(0.15)²/(0.028)

v = 12.25

Initial speed of stone = 12.25 m/s
