Force bc it says the ability to make stuff happen
98.4% of the power turns into heat.
If the bulb consumes 55 watts,
then it "wastes"
(0.984) x (55w) = 54.12 watts
D = 1/2gt^2 <-- free fall formula
d = (0.5)(9.81)(1.5^2)
d = 11.03625
d = 11.04 m
hope this helps and have a great day :)
Answer:
Explanation:
Due to changing magnetic field , there will be emf induced in the region . EMF induced will create electric field which will be circular in shape and will be uniform along its circular path
The magnitude of circular electric field can be calculated as follows
We should apply Faraday law of electro magnetic induction
e = - dФ / dt = - ∫ E dl
Here Ф = π r² B
π r² dB / dt = - ∫ E dl
π r² dB / dt = E x 2π r
E = - r / 2 x dB / dt
For a circular electric field having a particular radius , magnitude of field will be constant .
The direction of electric field will be known by lenz's law
In the given case , magnetic field is upwards and it is reducing , therefore electric field induced will be such as to prevent this change of flux.
So electric field will be anticlock-wise . Hence direction of acceleration will also be anticlock-wise on proton at 1.5 cm from the centre.
