Given the potential on a spherical shell of radius R to be V (R, θ) = V0 cos θ, calculate V (r, θ) both inside and outside the s

hell. From your result, determine the normal component of the electric field on either side of the shell, E+, and E−, and from them the charge on the shell σ(θ) = 0(E+ − E−). What is the total charge on the shell?

A batter hits a baseball with a bat. The bat exerts a force on the ball. Does the ball exert a force on the bat?
Mazyrski [523]

astra-53 [7]

Answer:

change 1000km into Metre

1000km=1000000 M

speed= distance/time

time=distance/speed

time=1000000/299792458

time= 0.0033second

If the caffeine concentration in a particular brand of soda is 2.97 mg/oz, 2.97 mg/oz, drinking how many cans of soda would be l
Ray Of Light [21]

Explanation:

The given data is as follows.

     Concentration of caffeine = 2.97 mg/oz

     Number of oz in a can = 12 oz

Therefore, the concentration of caffeine in one can is calculated as follows.

                 = (12 \times 2.97) mg

                 = 35.64 mg

                 = 35.64 \times 10^{-3} g

Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.

     No. of cans = \frac{\text{Lethal dose}}{\text{concentration in one can}}

                         = \frac{10 g}{35.64 \times 10^{-3} g}

                         = 280.58

                         = 281 (approx)

Thus, we can conclude that 281 cans of soda would be lethal.
