An image that a concave mirror can make is that it <span>can form a real image that is projected out in front of the mirror. </span>A concave mirror<span> is a mirror that is curved inward in the middle. Using the mirror equation, you can deal with concave mirrors. It's like you're looking into a cave when try to look in a concave mirror.</span>
Answer:
1. Daughter element : the new element produced along with a decay particle in a nuclear transmutation
2. half life: the time required for the decay of one-half of the atoms in a sample of radioactive material
3. parent element : the substance that decays in a nuclear transmutation
4. transmutation : the change of one chemical element into another by nuclear decay or radioactive bombardment
Explanation: Radioactive decay process is a type of process in which a less stable nuclei also called as parent element decomposes to a stable nuclei or a daughter element by releasing some radiations or particles like alpha, beta particles or gamma-radiations and the process by which one element changes to another element is called as transmutation.
Half life is the time taken by an element to decay to half of its initial value.
Answer:
-0.04194 V
Explanation:
= Number of turns in outer solenoid = 330
= Number of turns in inner solenoid = 22
= Current in inner solenoid = 0.14 A
= Rate of change of current = 1800 A/s
= Vacuum permeability = 
r = Radius = 0.0115 m
Magnetic field is given by
The average magnetic flux through each turn of the inner solenoid is
Magnetic flux is given by
Mutual inductance is given by
The mutual inductance of the two solenoids is
Induced emf is given by
The emf induced in the outer solenoid by the changing current inthe inner solenoid is -0.04194 V
Answer:
Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.
Explanation:
Answer:
Kinetic energy and potential energy.
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).
Work is also measured with the unit Joule (J).
