Answer: 248 Newton
Explanation:
force = rate of change of momentum
change of velocity
= 4 + 4 = 8 m/s
rate of change of momentum = mass per second x change of velocity
= 31 kg/s x 8 m/s
= 248 kg m/s^2 or Newtons
The time it will take the airplane to pass the radar station is 10.3 s.
<h3 /><h3>What is time</h3>
Time can be defined as the progression of event, from the past to the future through the present.
To calculate the time it will take the airplane to pass over the radar station, we use the formula below.
Formula:
- v = d/t............ Equation 1
Where:
- v = Velocity
- d = Distance
- t = Time
Make t the subject of the equation
- t = d/v.......... Equation 2
From the question,
Given:
Substitute these values into equation 2
- v = 1/350
- v = 0.00286 h
- t = 0.00286×3600 s
- t = 10.3 s
Hence, the time it will take the airplane to pass the radar station is 10.3 s.

unmmm u can say that it is going mt 15s
Answer:
1. The three main acidic gases responsible for lowering the pH of rainwater are non-metal oxides produced by the burning of fossil fuels like coal, oil and natural gas. Sulfur dioxide is produced when fossil fuels containing sulfur impurities are burned.
2. A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
3. The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4.
Answer- I would think low
