Till is unsorted glacial debris which is very dense and hard.
true
false

Option-(A): The following statement is true.

Explanation:

Due, to increase in the over all global warming the different regions of the globe are greatly effected by this effect and thus the glaciers too faces the same effect. As, there is a decrease in the over all sheet of glaciers across the planet resulting in rise in the water level and more rainfall.But, there are still some places which contains very large pieces of the continental glacier in it, same situation is for the Till which is an unsorted mass of glacier debris. The glacier is considered as on of the most dense and hardest body of ice.

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
