Answer:

The distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

Explanation:

Given that,

Charge, q=5\times 10^{-9}\ C

The end of her nose experiences an electric field strengths of 2200 N/C

It is required to find the distance between the tip of her nose from the center of the crystal ball. The formula of the electric field is given by :

E=\dfrac{kq}{r^2}

r is distance

r=\sqrt{\dfrac{kq}{E}} \\\\r=\sqrt{\dfrac{9\times 10^9\times 5\times 10^{-9}}{2200}} \\\\r=0.143\ m\\\\r=14.3\ cm

So, the distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

A ball is tossed up in the air. at its peak, it stops before beginning to fall. the ball at its peak has
Arte-miy333 [17]
The projectile (ball) reaches an instantaneous vertical speed (Vy) of zero at maximum height.

so, V(max height) = ¬Г(Vx)^2+(Vy)^2
in this case V(max height) = Vx, where Vy=0

The maximum height, Yf, can be solved using Vfy^2=Viy^2 + 2gy. At maximum height Vfy=0.

A block of mass 8 m can move without friction
nekit [7.7K]

Answer:

Let M1 = 8 kg and M2 = 34 kg

F = M a = (M1 + M2) a

F = M2 g     the net force accelerating the system

M2 g = (M1 + M2) a

a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2
