The horizontal component of the force is the product of the cosine of the angle and the magnitude of the force, Fx = (73.8 N)(cos 39) = 57.35 N. The vertical component of this force is the product of the sine of the angle and the force, Fy = (73.8 N)(sin 39) = 46.44 N.
Answer:
100 Hertz
1,000 Hertz
10,000 Hertz
Explanation:
Humans can detect frequencies between 20 Hz and 20,000 Hz.
Answer:
(i) C=3Co
(ii) V=Vo/3
(iii) Decrease
Explanation:
(i) capacitance increase K times.
(ii) As charge remain constant so by using Q=CV
you will get potential decrease by K time.
(iii) Decrease due to induced electric field inside
dielectric material..
E=Eo-Eind
Explanation:
heyaaa hope it helps ☺️✌️
Answer:
C) Use a battery with more voltage.
Explanation:
The equation for the magnetic field around a coil is given by,
B = μ₀NI
where,
B = Magnetic flux density
μ₀ = permeability
N = number of turns per meter
I = Current in the wire
So when using a higher voltage battery, more current passes through the battery as resistance of the wire remains the same.
Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
