Answer:

Centripetal force is the force on a body moving in a circle that points inward toward the point around which the object moves. The force in the opposite direction, pointing outward from the center of rotation, is called centrifugal force. For a rotating body, the centripetal and centrifugal forces are equal in magnitude, but opposite in direction

The work function for silver is 4.73 eV. (a) Convert the value of the work function from electron volts to joules.

pogonyaev

Answer:

$W=7.56\times 10^{-19}\ J$

Explanation:

Given that,

The work function for silver is 4.73 eV.

We need to find the value of the work function from electron volts to joules.

We know that,

$1\ eV=1.6\times 10^{-19}\ J$

For 4.73 eV,

$4.73\ eV=1.6\times 10^{-19}\times 4.73\\\\=7.56\times 10^{-19}\ J$

So, the work function for silver is $7.56\times 10^{-19}\ J$ .

Explain why does the bowling ball decelerate as it travels along the lane

frutty [35]

The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.

Luke Autbeloe drops an approximately 5.0 kg object (weight = 50.0 N) off the roof of his house into the swimming pool below. Upo

Murljashka [212]

Answer:

Graph B represents correct graph for velocity time

Explanation:

Initially the object is dropped under the influence of constant force due to gravity

So here we can say its acceleration is constant due to gravity

hence here the velocity will increase downwards due to gravity and it is given as

$v = 0 + (-10)t$

now when it enters into the pool an upward force of same magnitude will act on it

so net force on it is

$F = 50 - 50 = 0$

so here we will have no acceleration and it will move with constant speed after that

so here correct graph is

Graph B
