6 0

Answer:

the force exerted on the charge 10 q have a magnitude that is greater than F

Explanation:

The relation between the force and the charge are direct proportionality, it implies that as the charges is increasing the forces will be increasing too

Ask Your Teacher William Tell shoots an apple from his son's head. The speed of the 120-g arrow just before it strikes the apple
svlad2 [7]

Answer:

 M = 0.115 kg

Explanation:

given,

mass of arrow = 120 g = 0.12 Kg

speed of arrow before it strike apple = 29.7 m/s

distance traveled by the arrow stick combination = 9.30 m

height of the son = 1.85 m

weight of the apple = ?

now,

time of flight of arrow and apple combination

using equation of motion

h = u t + \dfrac{1}{2}gt^2

h = \dfrac{1}{2}gt^2

t = \sqrt{\dfrac{2h}{g}}

t = \sqrt{\dfrac{2\times 1.85}{9.8}}

t = 0.614 s

speed = \dfrac{distance}{time}

s = \dfrac{9.30}{0.614}

    s = 15.15 m/s

using conservation of momentum

 m v = (M+ m) s

 0.12 x 29.7 = (M+ 0.12) x 15.15

 M+ 0.12 = 0.235

 M = 0.115 kg

mass of apple is equal to 0.115 Kg

Suppose we wrap a string around the surface of a uniform cylinder of radius 38.0 cm that is supported by an axle passing through
liraira [26]

Answer:

Angular acceleration = 23.68 rad / s²

Explanation:

Given that,

acceleration = 9m/s²

Therefore acceleration of string is 9m/s²

since string is constant in length

cylinder of radius 38.0 cm = 0.38m

Angular acceleration = a / r

Angular acceleration = 9 / 0.38

                                   = 23.68 rad / s²

Angular acceleration = 23.68 rad / s²
