It can travel 2,025 km.

Hope this helps.

In 1920, after returning from Army service, he produced a successful model and in 1923 turned it over to the Northeast Electric Company of Rochester for development.

**light and radiation** is able to experience by an observer watching the explosion from the vacuum.

<u>**Explanation:**</u>

- Basically in the
**nuclear explosion, there will be an enormous of energy released as noise, heat, visible light, radiation and atmospheric wave**.
- Usually
**sound and wave propagate through medium** but in **vacuum, there will be no medium to transfer this type of energy**. so there is no chance of sound and wave transfer. **Light and radiation travel in vacuum** because they **didn't need the medium to transfer** .

We know the equation

weight = mass × gravity

To work out the weight on the moon, we will need its mass, and the gravitational field strength of the moon.

Remember that your weight can change, but mass stays constant.

So using the information given about the earth weight, we can find the mass by substituting 100N for weight, and we know the gravity on earth is 10Nm*2 (Use the gravitational field strength provided by your school, I am assuming yours in 10Nm*2)

Therefore,

100N = mass × 10

mass= 100N/10

mass= 10 kg

Now, all we need are the moon's gravitational field strength and to apply this to the equation

weight = 10kg × (gravity on moon)

There is an easy and convenient technique to solve vectors without drawing them. With you scientific calculator, make sure that you are in mode CMPLX. In this case, the two vectors should sum up to the resultant vector. Since we are given with the resultant vector, let's just use subtraction. Input this into your calculator:

96.3∠75.2° - 56.4∠232°

The answer would be 59.32+137.55i. Convert this to the r∠θ format. The final answer would be 149.8∠66.67°.** Therefore, the second displacement is 149.8 cm and makes an angle of 66.67° with the +x axis.**
