Using the same antenna. Now he doesn't know if it was the antenna that caused the change in reception. so he wasn't only measuring the reception in his house he was measuring it based on different antennas
In short, the key value added of CDR data over census or survey approaches is the potential to access current and comprehensive evidence on population size, density, and dynamics, information that is fundamentally necessary for managing any humanitarian emergency or disease-related disaster but which is often
It decomposes into CH3COO- and H+ when dissolved in water. The H+ ions react with the water molecules to generate H3O+, making the solution acidic. When NaOH is added to water, it separates into Na+ and OH-. The sodiums have little effect on the solution, but the hydroxyls make it more basic.
Answer:
The new speed of the ball is 176.43 m/s
Explanation:
Given;
mass of the ball, m = 7 kg
initial speed of the ball, u = 5 m/s
applied force, F = 300 N
time of force action on the ball, t = 4 s
Apply Newton's second law of motion;
![F = ma = \frac{m(v-u)}{t}\\\\m(v-u) = Ft\\\\v-u = \frac{Ft}{m}\\\\v = \frac{Ft}{m} + u](https://tex.z-dn.net/?f=F%20%3D%20ma%20%3D%20%5Cfrac%7Bm%28v-u%29%7D%7Bt%7D%5C%5C%5C%5Cm%28v-u%29%20%3D%20Ft%5C%5C%5C%5Cv-u%20%3D%20%5Cfrac%7BFt%7D%7Bm%7D%5C%5C%5C%5Cv%20%3D%20%20%5Cfrac%7BFt%7D%7Bm%7D%20%2B%20u)
where;
v is new speed of the ball
![v = \frac{Ft}{m} + u\\\\v =\frac{300*4}{7} + 5\\\\v = 176.43 \ m/s](https://tex.z-dn.net/?f=v%20%3D%20%20%5Cfrac%7BFt%7D%7Bm%7D%20%2B%20u%5C%5C%5C%5Cv%20%3D%5Cfrac%7B300%2A4%7D%7B7%7D%20%2B%205%5C%5C%5C%5Cv%20%3D%20176.43%20%5C%20m%2Fs)
Therefore, the new speed of the ball is 176.43 m/s
Answer:
(A) Gravity is you're answer.
Explanation:
When an object or human is falling at an increased rate, The force of gravity is taking place.
