Then its acceleration must decrease, by the same factor as you increased the mass.
The PRODUCT of the (mass) times (acceleration) doesn't change.
It's equal to the force acting on the mass. (Newton #2: F = M·A.)
So, since the product has to remain constant, if you multiply the mass
by something, then the acceleration will divide by the same thing.
Taking into account the definition of electron affinity, negative electron affinity means that the anion of the element is more stable than the neutral atom.
Electron affinity is the energy exchanged when a neutral, gaseous atom, and in its ground state, captures an electron to form the anion.
In other words, electronon Affinity is the energy that is given off when a neutral atom in the gaseous state captures an electron to become a negative ion.
The value can be positive or negative. A negative electron affinity means energy must enter in order to bind an electron to the ion, being an endothermic process. If electron affinity is positive, the process is exothermic and occurs spontaneously.
Then, the negative electron affinity (energy is released) occurs when the atoms acquire a more stable configuration when capturing an electron, so the attractive force will predominate. Positive electron affinity (energy is absorbed): occurs when you have to provide energy to the atom to capture the ion.
In summary, negative electron affinity means that the anion of the element is more stable than the neutral atom.

Answer: increase the amount of work that is done?
Explanation:
I’m not entirely sure to be honest but I’ll just use my logic here. Machines are made to increase efficiency and production. Machines are made to save time and energy as a pose to human work. So several machines can mass produce a lot of things and keep business booming. I’m not very good at explaining things but I hope this makes sense eventually.
Answer:
Maximum height reached is given as H = 5.00 m
Explanation:
As we know that if the ball is projected at some angle with the horizontal then the range of the projectile is given by the formula
![R = \frac{v^2 sin2\theta}{g}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7Bv%5E2%20sin2%5Ctheta%7D%7Bg%7D)
here we have
![R = 55 m](https://tex.z-dn.net/?f=R%20%3D%2055%20m)
![\theta = 20^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2020%5Eo)
v = 40 m/s
Now we have
![55 = \frac{40^2 sin40}{g}](https://tex.z-dn.net/?f=55%20%3D%20%5Cfrac%7B40%5E2%20sin40%7D%7Bg%7D)
![g = 18.7 m/s^2](https://tex.z-dn.net/?f=g%20%3D%2018.7%20m%2Fs%5E2)
now for maximum height we have
![H = \frac{v^2sin^2\theta}{2g}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7Bv%5E2sin%5E2%5Ctheta%7D%7B2g%7D)
![H = \frac{40^2 sin^220}{2(18.7)}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B40%5E2%20sin%5E220%7D%7B2%2818.7%29%7D)
![H = 5 m](https://tex.z-dn.net/?f=H%20%3D%205%20m)
