Answer:
0.32 V
Explanation:
N = 10, A = 0.23 m^2, B = 0.47 T, t = 0.34 s
The average induced emf is given by
e = - N dФ / dt
Where, dФ be the change in magnetic flux in time dt.
dФ / dt = d / dt (B A) = A dB/dt
So,
e = - 10 x 0.23 x 0.047 / 0.34 = - 0.32 V
The negative sign shows the direction of induced emf.
Answer: Inertia
Explanation: If it is multiple choice chose acceleration and inertia
Answer: Yes, on many slate-roofed homes as temperatures change, such as cooling at night or heating during the day, thermal expansion or contraction of the slates may cause movement that in turn causes snapping, popping, or cracking noises, even bangs and clanks or clicks from the roof.
Explanation:
Answer:
If she bends forward
Explanation:
because the equilibrium of gravity will not stay the same causing her to move forward
An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
DescriptionAn exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.
Hope this helps :)
