A) similar to what you see in your textbook, you can generally omit the multiplication symbol as you answer questions online, except when the symbol is needed to make your meaning clear. for example, 1⋅105 is not the same as 1105. when you need to be explicit, type * (shift + 8) to insert the multiplication operator. you will see a multiplication dot (⋅) appear in the answer box. do not use the symbol ×. for example, for the expression ma, typing m ⋅ a would be correct, but mxawould be incorrect.

ma=

b) enter the expression 2cos2(θ)−1, where θ is the lowercase greek letter theta.

2cos2(θ)−1 =

c) enter the expression asin(x)+15, where asin(x) is the inverse sine function.

asin(x)+15 =

d) enter the expression (√(2gδy)/m), where δ is the uppercase greek letter delta.

(√2gδy/m)=

e) enter the expression n0e−λt, where n0 is n-naught (an n with a subscript zero) and λ is the lowercase greek letter lambda.

n0e−λt=

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
