Answer:
The emf, electric field and the current in the wire are 10 V, 3.57 V/m and 1.43 A.
Explanation:
Given that,
Resistance = 7 ohms
Length = 2.8 m
Time t =0.2
We need to calculate the change in magnetic flux
Using formula of induced emf
Put the value into the formula
We need to calculate the electric field in the wire
Using formula of electric field
We need to calculate the current in the wire,
Using formula of ohm's law
Put the value into the formula
Hence, The emf, electric field and the current in the wire are 10 V, 3.57 V/m and 1.43 A.
Answer:
350 Kg
Explanation:
We use the Work Formula:
W = Force . Distance
33.000 Joules = Force . 6
Force = 5500 Newtons
Force = Mass . Acceleration
5500 = Mass . 10
Mass = 550
550 - 200 = 350 Kg
Answer:
Learned helplessness can have a profound impact on mental health and well-being. People who experience learned helplessness are also likely to experience symptoms of depression, elevated stress levels, and less motivation to take care of their physical health. Not everyone responds to experiences the same way.

Brainlist will be very accepted ;D *wink*
The most important characteristics that are exhibited by metals are-
1- Metals are ductile
2-Most metals are conductive in nature.
3-Most metals are malleable.
4- Metals have strong inter molecular force of attraction between the.
5-Metals have luster.
6-Metals are sonorous.
Here we are given Tungsten filament.
Tungsten is a metal.So it must be conductive and as well as ductile in nature.
The electric filament that we are using in our electric bulb glows due to the heating effect of current.Hence the chosen substances for glowing electric bulb must have high melting point.
The melting point of tungsten is 1650 degree celsius which is very high.That's why it is used in electric bulb.
Hence the correct answer to the question is the third one i.e Tungsten is ductile,has a high melting point, and is electrically conductive.
