Answer:
e = 30 V
Explanation:
given,
N = 30 turns
Area = 0.25 m²
angular speed = ω = 100 rad/s
Magnetic field = 0.04 T
maximum induced emf in the loop = ?
e = N B A ω
e = 30 x 0.04 x 0.25 x 100
e = 30 V
hence, the maximum emf induced in the loop is equal to e = 30 V
The answer is A because An Indicator" changes color when it comes in contact with an acid or a base
An indicator could be anything like:
1) Litmus paper
2) Bromothymol blue
3) Phenolphthalein
Answer:
5 m/s^2 will be the acceleration
Explanation:
comment down for further explanation if you want
Formula for potential energy is:
pe = m * g * h
Where:
m = mass of an object
g = gravitational acceleration
h = height at which object is placed
From this equation we can make conclusion that increasing mass also increases potential energy. Object b has double the mass so it has double the potential energy.
Object a:
pe = m * 9.81 * 1
pe = 9.81 J
Object b:
pe = 2m * 9.81 * 1
pe = 19.62 J
Cada 100 cm es de 1 m por lo que tomar los kilos a su vez a cm, a continuación, a su vez a metros
