if the electron affinity for an element is a negative number, does it mean that the anion of the element is more stable than the neutral atom?
No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.
We know that,
Kinetic energy is defined as the energy of the object that occurs due to the motion of the object. The total work needed by the body to starts accelerating it by the help of given mass which is supplied from the rest position and its mentioned velocity.
The energy body gets due to the process of acceleration by this the body will able to main the kinetic energy of the body without changing the speed of the body.
The energy which has been stored in the body or any object by the help of the particular position or the proper arrangement of the parts is known as potential energy.
There will be no effect of the outside environment on the potential energy that present inside the body.
The kinetic energy decrease or increase with change into the velocity.
Therefore, No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.

Andy took a bus and then walked from his home to downtown. For the first 1.6 hour, the bus drove at an average speed of (15km)/(h). For the next 0.4 hours, he walked at an average speed of (4.5km)/(h). What was the average speed for the whole journey?
Answer:

Explanation:
A projectile is shot on level ground with a
horizontal velocity of 17 m/s and a vertical
velocity of 34 m/s.
-Find the time the projectile is in the air.
The acceleration due to gravity is 9.8 m/s2.
Answer in units of s.
-Find range R.
Answer in units of m.
Answer:
time rising = 34 / 9.8 = 3.47 sec
total time in air = 2 * 3.47 sec = 6.94 sec
(time rising must equal time falling)
R = 17 m/s * 6.94 s = 118 m
Can also use range formula
R = v^2 sin (2 theta) / g
tan theta = 34 / 17 = 2
theta = 63.4 deg
2 theta = 126.9 deg
sin 126.9 = .8
v^2 = 17^2 + 34^2 = 1445 m^2/s^2
R = 1445 * .8 / 9.8 = 118 m agreeing with answer found above

Please help me to solve this question .
Answer:
P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s
Momentum is conserved
P1 = P2 = V * (M + m) = .16 kg-m/sec
V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec

what makes it difficult to see Mercury
Answer:
Mercury is the planet nearest the Sun and is the most difficult to observe, because it is always quite close to the Sun in the sky. Because of its orbital motion, it appears to swing back and forth around the Sun, reaching a maximum angular distance of about 28°.
Explanation:
I hope that helps you
Answer:
Mercury is very close to the Sun which means its hard to see the planet without the Sun's brightness outshining it. It is also the smallest planet in the solar system.
Hope this helps!

The weight of the stone is 10N.
To find the weight of the stone, we need to know about the gravitational force on any object due to earth.
What is gravitational force?Gravitational force is a attractive force that arises between any two objects. The objects, on the earth surface or near the earth surface, experience the gravitational force of earth. This gravitational force is Known as the weight of the object. How can we calculate the gravitational force or the weight of an object, when it's near the earth surface?When an object is near the earth surface, its weight is mass × gravitational acceleration (g).
So, the weight of the stone= 1kg × 10 m/s²
= 10 N
Thus, we can conclude that the weight of the stone 100 m above a gorge is 10N.

if a person with a mass of 70kg is standing on scale in an elevator when the cable snaps, what will the reading on the scale be during free-fall?
Answer:
The reading will be the same.
Explanation:
Mass does not depend upon anything and it remains the same anywhere. What changes is the weight of the body because it depends upon gravity and is different at different places.
Giving me the brainest will be helpful.
The reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.
What is a weighing scale?A weighing scale known as a balance is a device used to quantify weight or mass. The classic scale is made up of two plates or bowls that are suspended at equal distances from a fulcrum.
A person with a mass of 70kg is standing on a scale in an elevator suddenly the cable snaps, The reading on the scale during free-fall will be the same as the initial elevator condition.
Hence the reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.
