Compare the outermost electrons of an atom with the inner most electrons of an atom in terms of energy

Answers

Answer 1

Answer: The innermost electron of an atom has the lowest level of energy while the outermost electron has the highest level of energy.
There are different energy levels in the atoms of elements, for an atom to go into an higher level it has to obtain more energy and to go to lower level it has to lose energy.

When a baseball player catches a baseball, the glove "gives" or moves backward. How does this movement affect the change in momentum of the baseball? The change in momentum increases because the impact time increases. The change in momentum decreases because the force decreases. The change in momentum stays the same because the ball still comes to a stop. The change in momentum depends on the initial speed of the ball and the time to stop.

If a radio and a bulb each of resistance 3 ohm are connected in series to a 12 volts battery, the potential difference across each will be;a) 3V

b) 6V

c) 12V

d) 9V

Can u please solve and then explain answer

Answers

Answer:

$\rm{Option \:B) \: 6V}$

Explanation:

Given resistance of the radio is 3Ω and the resistance of the bulb is 3Ω. The total resistance in the circuit is

$R_1 + R_2 = 6 Ω</p><p>$

NowapplyOhm'sLaw,

$V \:=\: IR$

The voltage of the battery is V = 12V. And we have the total resistance of the circuit. Substituting the values to find current:

$I = 12 V / 6 Ω = 2A$

The potential difference across the radio or the bulb (using V = IR) is:

$V = 3 * 2 = 6V$

~The answer is option(b) 6 volts.

Explanation:

Cliff divers at Acapulco jump into the sea from a cliff $30.7 m$ high. At the level of the sea, a rock sticks out a horizontal distance of $9.34 m$.The acceleration of gravity is $9.8 m / s ^{2}$.
With what minimum horizontal velocity must the cliff divers leave the top of the cliff if they are to miss the rock?
Answer in units of $m / s$.

Answers

Answer:

To solve this problem, we can use the kinematic equation for horizontal motion, which relates the initial velocity ($v_{0}$), final velocity ($v_{f}$), acceleration ($a$), and displacement ($d$) of an object:

$d = v_{0} t + \frac{1}{2}at^{2}$

In this case, we want to find the minimum initial velocity ($v_{0}$) that the divers must have to clear the rock. To do this, we can assume that the divers just graze the rock at the start of their trajectory, so the displacement in the horizontal direction is equal to the distance from the cliff to the rock ($d = 9.34 m$). We also know that the acceleration in the horizontal direction is zero, so the only force acting on the divers is gravity in the vertical direction, which gives an acceleration of $a = 9.8 m/s^{2}$.

At the instant the divers leave the cliff, they have zero horizontal velocity, so $v_{0} = 0$. We can use the equation above to solve for the time it takes for the divers to fall from the cliff to the level of the rock:

$d = \frac{1}{2}at^{2} \Rightarrow t = \sqrt{\frac{2d}{a}}$

Plugging in the numbers, we get:

$t = \sqrt{\frac{2(9.34 m)}{9.8 m/s^{2}}} \approx 1.44 s$

Since the cliff divers want to clear the rock, they need to travel a horizontal distance of at least $9.34 m$ during this time. We can use the equation for horizontal motion again to solve for the minimum initial velocity:

$d = v_{0}t \Rightarrow v_{0} = \frac{d}{t} = \frac{9.34 m}{1.44 s} \approx 6.49 m/s$

Therefore, the minimum horizontal velocity that the cliff divers must have to clear the rock is approximately $6.49 m/s$.
