Answer:
The correct solution is "37.5 km".
Explanation:
Given:
Distance between the trains,
d = 75 km
Speed of each train,
= 15 km/h
The relative speed will be:
= 
= 
The speed of the bird,
V = 15 km/h
Now,
The time taken to meet will be:
hence,
The distance travelled by the bird in 2.5 h will be:
⇒ 
Answer:
.864 M
Explanation:
For first order decomposition,
rate constant k = 1/t x ln a / (a - x )
given , a = 1.33 M , t = 644 s , k = 6.7 x 10⁻⁴ , a - x = ? = b( let )
6.7 x 10 ⁻⁴ = 1/644 x ln 1.33/b
ln 1.33/b = 6.7 x 10⁻⁴ x 644 = .4315
1.33 / b = e⁰ ⁴³¹⁵ = 1.5395
b = 1.33 / 1.5395 = .864 M.
A product line is a group of
products offered by a firm that are closely related to each other, either in
terms of how they work, or the customers they serve. An example is the production
of wine, beer, spirit, whiskey, vodka. These products may be different but they
are related because they are all alcohol liquor.
I think the answer should be that, Kinetic energy is contained in a moving object, while potential energy exists in a stored form.
