Explanation:
It is given that,
Length of side of a square, l = 24 cm = 0.24 m
The uniform magnetic field makes an angle of 60° with the plane of the coil.
The magnetic field increases by 6.0 mT every 10 ms. We need to find the magnitude of the emf induced in the coil. The induced emf is given by :

is the rate of change if magnetic flux.

is the angle between the magnetic field and the normal to area vector.





or
EMF = 60 mT
So, the magnitude of emf induced in the coil is 60 mT. Hence, this is the required solution.
Answer:


Explanation:
given,
mass of asteroid 1 = M
mass of asteroid 2 = 2M
radius of two asteroid = R
Distance between the asteroid = 10 R
Speed of the asteroid before collision = ?
using conservation of momentum
M u + 2M u' = M v₁ + 2 M v₂
initial speed of asteroid is equal to zero
0 = v₁ + 2 v₂
v₁ = -2 v₂
using conservation of momentum
initial potential energy is converted into potential energy and the kinetic energy of both the asteroids.




now,


hence, the velocity of asteroid are


The difference is one is a written formula that describes a molecule, the other is a visual representation of the molecule. for example the hydrocarbon butane has a molecular formula of C4H10, whereas the molecular model would depict 4 Carbon atoms (either represented by colour coded dots or the letter C) with single bonds (one straight line) connecting them to the 10 Hydrogen atoms (either differenly coloured dots or a H)
Electric force is typically weaker than gravitation force.
