A.warm waters from the gulf stream
Answer:
Statement 2 is wrong
Explanation:
To check the statements in this exercise, let's describe the main properties of electromagnetic waves. Let's describe the characteristics
* they are transverse waves
* formed by the oscillations of the electric and magnetic fields
* the speed of the wave is the speed of light
with these concepts let's review the final statements
1) True. Formed by the oscillation of the two fields
2) False. They are transverse waves
3) True. Can travel by vacuum as they are supported by oscillations of the electric and magnetic fields
4) True. They all have the same speed of light
Statement 2 is wrong
Answer:
For uniform acceleration
a = (v2 - v1) /t = 2.5 acceleration is constant 2.5
v2 = 2.5 * 4 v1 = 0 at t = 0
v2 = 2.5 m/s^2 * 4 s = 10 m/s
A 1Msun star in a closed binary system with a 2Msun star.
Systems in which the two stars are close to each other are called close binary star system.
The most massive stars have the shortest lifespans. The reason is that they have most fuel, they burn it so enormously that their lifetimes are very short. As a 1Msun star in a closed binary system with a 2Msun star becomes the massive star so it has the shortest life expectancy.
a. No, an isolated 1Msun star has not the shortest life expectancy.
b. No, a 1Msun star in a closed binary system with a 0.8Msun star has not the shortest life expectancy.
c. Yes, A 1Msun star in a closed binary system with a 2Msun star has the shortest life expectancy.

Answer:
Below
Explanation:
To find the velocity of the person you can use this formula
velocity = displacement / time
velocity = 13.09 km / 2.371 hours
velocity = 5.5208 km/h
= 5.521 km/h
