Answer:
the final velocity of the cart is 30 m/s
Explanation:
Given;
initial velocity of the cart, u = 10 m/s
distance moved by the cart, d = 200 m
acceleration of the cart, a = 2.0 m/s²
The final velocity of the cart is calculated as;
v² = u² + 2ad
where;
v is the final velocity
v² = 10² + 2(2)(200)
v² = 900
v = √900
v = 30 m/s
Therefore, the final velocity of the cart is 30 m/s
We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.

The type of stars in the areas give different colors to the galactic disk. The galactic disk appears blue because it has a large proportion of young, hot, main-sequence stars. The galactic bulge appears red because it contains many red giants and supergiants. The reddish hue of the galactic bulge indicates that new stars aren't being formed there.
Explanation:
This problem is pretty straight forward since we are given
the half time and we simply have to find for the rate constant. The equation
relating the two variable is:
t1/2 = ln(2) / k
where k is the rate constant, therefore:
k = ln(2) / t1/2
k = ln(2) / 14.7 h
<span>k = 0.047 / hour</span>
