I would assume that the magnesium would have to come into contact with an ion in order to become a magnesium ion.
Answer:neutron
Explanation:
Because it is similar to the motor neurons
Answer:
Yes it is. So
B. True
Explanation:
Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.
Answer:
Force, F = 44 N
Explanation:
Given that,
Initial speed of the football, u = 0
Final speed, v = 15 m/s
The time of contact of the ball, t = 0.15 s
The mass of football, m = 0.44 kg
We need to find the average force exerted on the ball. It is given by the formula as :
![F=ma\\\\F=\dfrac{mv}{t}\\\\F=\dfrac{0.44\times 15}{0.15}\\\\F=44\ N](https://tex.z-dn.net/?f=F%3Dma%5C%5C%5C%5CF%3D%5Cdfrac%7Bmv%7D%7Bt%7D%5C%5C%5C%5CF%3D%5Cdfrac%7B0.44%5Ctimes%2015%7D%7B0.15%7D%5C%5C%5C%5CF%3D44%5C%20N)
So, the average force exerted on the ball is 44 N. Hence, this is the required solution.
