A conducting sphere 45 cm in diameter carries an excess of charge, and no other charges are present. You measure the potential o

uysha [10]

Answer:

The excess charge is $Q = 3.5 *10^{-7} \ C$

Explanation:

From the question we are told that

The diameter is $d = 45 \ cm = 0.45 \ m$

The potential of the surface is $V = 14 \ kV = 14 *10^{3} \ V$

The radius of the sphere is

$r = \frac{d}{2}$

substituting values

$r = \frac{0.45}{2}$

$r = 0.225 \ m$

The potential on the surface is mathematically represented as

$V = \frac{k * Q }{r }$

Where k is coulomb's constant with value $k = 9*10^{9} \ kg\cdot m^3\cdot s^{-4} \cdot A^{-2}.$

given from the question that there is no other charge the Q is the excess charge

Thus

$Q = \frac{V* r}{ k}$

substituting values

$Q = \frac{14 *10^{3} 0.225}{ 9*10^9}$

$Q = 3.5 *10^{-7} \ C$

An arrow is shot at a target 20 m away. The arrow is shot with a horizontal velocity of 80 m/s.

Verdich [7]

(1) The time of motion of the arrow is 0.25 s.

(2) The vertical height dropped by the arrow as it approaches the target is 0.31 m.

The given parameters:

Horizontal distance of the arrow, X = 20 m
Horizontal speed of the arrow, v = 80 m/s

The time of motion of the arrow is calculated as follows;

$t = \frac{X}{v} \\\\t = \frac{20 }{80} \\\\t = 0.25 \ s$

The vertical height dropped by the arrow as it approaches the target is calculated as follows;

$h = v_0_y t + \frac{1}{2} gt^2\\\\h = 0 \ + \ \frac{1}{2} \times 9.8 \times 0.25^2\\\\h =0.31 \ m$

A 20 newton force moves an object southeast. What two properties of force have been described?

Galina-37 [17]

Answer:

The answer is C

Explanation:

Force is a vector quantity so it has both magnitude and direction. The question shows 20N act as magnitude and Southeast act as direction.
