Answer:
a) 58 Hz b) 7.73 mV
Explanation:
From the complete question we are given that
Radius of the semi circle , a = 3.0 cm = (3.0)(1 × m/1 cm)
=3.0 × m
Angular speed ,w = 58 rev/s
= (58 rev/s)(2π rad /1 rev)
= 364.4 rad/s
Magnetic field, B = 15 mT
= (15 mT)(1 × T/ 1 mT)
= 15 × T
a) f = 58 rev/s
= 58 Hz
b) The Induced emf, ∈ = ω<em>Bπ</em> /2
= T)(π)(3.0 × m)^2)÷2[/tex]
= 0.007728 V
= 7.73 mV
The answer is false because kinetic energy contains motion!
Answer:
1200N
Explanation:
Suppose a body of mass "m" and its weight on the moon is Wm (where W is the weight and "m" is the moon ;which means weight on the moon).Mass of the moon is "M"
and its radius is "R"
Weight of an object on the moon = "F"(Force)with which the moon pulls.
Wm = GM*m/r2
Weight of the same object on the earth is We(where W is the weight and "e" is the earth; which means weight on the earth).
Mass of the earth is 100 times of that of the moon.
Radius of the moon = R
Radius of the Earth = 4R
Weight of the object on the moon =
We = G100M*m/(4R)2(Pronounced 4 R square)
We = G100M*m/(16R)2(Pronounced 16 R square)
Wm/We = G * M * m * 16R2/R2 * g * 100M * m
=16/100
Therefore, 4800N on earth= 1200N on moon
The law of conservation of mass<span> states that </span>mass<span> in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the </span>law of conservation of mass<span>, the </span>mass<span> of the products in a chemical reaction must equal the </span>mass<span> of the reactants.
</span>
Every chemical equation<span> adheres to the </span>law of conservation of mass<span>, which states that </span>matter<span> cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical </span>equation.
