Answer:

both experience forces or at least a force

Explanation:

it would go in the direction the other object

(second object, the one that crashed) was going

si if going right then right if left then left

plus or minus

If the direction of the position is north and the direction of the velocity is up, then what is the direction of the angular mom

Kay [80]

Answer:

the direction of angular momentum = EAST

Explanation:

given

Direction of position = r = north

Direction of velocity = v = up

angular momentum = L = m(r x v)

where m is the mass, r is the radius, v is the velocity

utilizing the right hand rule, the right finger heading towards the course of position vector and curl them toward direction of velocity, at that point stretch thumb will show the bearing of the angular momentum.

then L = north x up = East

A brick is resting on the surface of a flat board. as one end of the board is slowly raised, what change, if any, is there in th

vovangra [49]

The normal force decreases, this is the frictional force. It will be counteracted by the force which accelerates the brick to slide downward opposite to the end where the board is raised. As the angle increases the force acting upon the brick opposite to the normal force will decrease.

(a) Find the voltage near a 10.0 cm diameter metal sphere that has 8.00 C of excess positive charge on it. (b) What is unreasona

antoniya [11.8K]

Answer:

Part a)

$V = 7.2 \times 10^{11} Volts$

Part b)

this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.

Part C)

here we can assume the sphere is placed at vacuum so that there is no break down of air.

Explanation:

Part a)

As we know that the potential near the surface of metal sphere is given by the equation

$V = \frac{kQ}{R}$

here we have

Q = 8 C

R = 10.0 cm

now we have

$V = \frac{(9\times 10^9)(8 C)}{0.10}$

$V = 7.2 \times 10^{11} Volts$

Part b)

this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.

Part C)

here we can assume the sphere is placed at vacuum so that there is no break down of air.
