Why does a mountain of uranium not explode as a bomb?

djyliett [7]

Answer:

“A mountain of uranium” is an indefinable amount of uranium. If it means uranium ore as found in nature, then the concentration of uranium is orders of magnitude too low for any type of reaction.

g A projectile of mass 3 kg is launched horizontally from an initial height 3 m with an initial velocity 10 m/s. This velocity i

Ierofanga [76]

Answer:

The kinetic energy at ground will be "238.2 J".

Explanation:

The given values are:

mass,

m = 3 kg

Initial height,

h = 3 m

Initial velocity,

v = 10 m/s

By using the conservation of energy at points A and B,

⇒ $E_A=E_B$

⇒ $mgh+\frac{1}{2}mv^2=k_B$

On substituting the values, we get

⇒ $3\times 9.8\times 3+\frac{1}{2}\times 3\times (10)^2=k_B$

⇒ $88.2+0.5\times 3\times 100=k_B$

⇒ $88.2+150=k_B$

⇒ $238.2 =k_B$

An object is thrown vertically upward with an initial velocity of 10 m/sec from a height of 3 meters. In meters, find the highes

Kaylis [27]

Answer: Highest point from the ground that ball reaches = 5.102

Explanation:

Formula -

v² - u² = 2as

final velocity v = 0

initial velocity u = 10m/s

acceleration a = g (gravity)=9.8

distance s = 3m+x (x is the height after 3m that object reaches)

0-(10)² = 2 (-g)*(3+x)

-100 = -2g*(3=x)

(3+x)=100/2g

3+x = 100/2*9.8 = 100/19.6 = 5.102

x=5.102-3

x=2.102

So, the highest point will be

3+x = 3+2.102

=5.102m
