Answer: 3
Explanation:
The water molecule is H2O. 2 hydrogen atoms are bonded to one oxygen atom. Therefore there are 3 individual atoms in 1 molecule of water. 2 different TYPES of atoms, but 3 individual atoms.
Answer:
East to west.
Explanation:
According to Newton's second law of motion, the acceleration of an object is in the same direction as the net force acting on it.
Explanation:
Given that,
Radius of the circular loop, r = 3.5 cm = 0.035 m
(a) During a 0.12-s time interval, the magnitude of the field increases uniformly from 0.2 T to 0.5 T. Due to the change in the magnetic field, an emf will induced in it. The magnitude of induced emf is given by :
So, the magnitude of the emf induced in the loop during the time interval is .
(b) The negative sign shows that the direction of induced emf in the loop is in anitclockwise direction.
Answer:
There is no way of knowing the phase composition without more information
Explanation:
For equilibrium to be established quantity of heat loss by the water must equal to the quantity of heat gain by the ice since the container is insulated which rules out loss of heat to the environment. To be able to the determine the phases present we need the temperature of the water as well as the temperature of the ice, mass of the water present and the mass of the ice . These two are not given, we therefore do not have enough information to determine the phases present even when we can easily get the values of specific heat capacity and latent heat of fusion.
