Answer: The distance that we'll be travelled is d=16.35m
Explanation: The main idea here is to use the equation of motion. We are given the acceleration of 2m/s^2,the initial and final velocies. The formula to use is v^2=u^2+2as. Now we have to substitute the values.
2^2= 8.33^2+2(2)d
d= 16.35m
Stars<span> are </span>classified<span> by their spectra (the elements that they absorb) and their temperature. There are seven main types of </span>stars. In order of decreasing temperature, O, B, A, F, G, K, and M. Type O stars are the stars with the highest temperature and biggest luminosity. So, if there is a <span>new born star cluster : 1. with one O star,
2. with 10 A stars,
3. with 10 G stars,
4. with 1000 M stars
</span><span>the stellar type O will dominate the light output from the cluster.</span>
Answer:
d) 1/4 F
Explanation:
The magnitude of electrostatic force between stationary charges is described by Coulomb's law. This law states that this force is proportional to the magnitudes of the charges:
When each of the spheres has lost half its initial charge, we have:
So, the new electrostatic force is:
The object will sink in any liquid whose density is less than 0.75 g/mL .
A few examples are butane, ether, gasoline, hexane, octane, naphtha, pentane, and propane.
