We will apply the conservation of linear momentum to answer this question.
Whenever there is an interaction between any number of objects, the total momentum before is the same as the total momentum after. For simplicity's sake we mostly use this equation to keep track of the momenta of two objects before and after a collision:
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
Note that v₁ and v₁' is the velocity of m₁ before and after the collision.
Let's choose m₁ and v₁ to represent the bullet's mass and velocity.
m₂ and v₂ represents the wood block's mass and velocity.
The bullet and wood will stick together after the collision, so their final velocities will be the same. v₁' = v₂'. We can simplify the equation by replacing these terms with a single term v'
m₁v₁ + m₂v₂ = m₁v' + m₂v'
m₁v₁ + m₂v₂ = (m₁+m₂)v'
Let's assume the wood block is initially at rest, so v₂ is 0. We can use this to further simplify the equation.
m₁v₁ = (m₁+m₂)v'
Here are the given values:
m₁ = 0.005kg
v₁ = 500m/s
m₂ = 5kg
Plug in the values and solve for v'
0.005×500 = (0.005+5)v'
v' = 0.4995m/s
v' ≅ 0.5m/s
The statement is an opinion because it expresses a preference of an individual than an actual fact.
PH measures the concentration of hydrogen ions (
) in a solution. Knowing this, you can determine how acidic -or basic- your solution is.
Answer:
ρ = 1.70 Ωm
Explanation:
given data
diameter = 1.8 mm
distance = 4.8 cm
volt = 9 V
potential difference = 280
solution
we know that Resistance that is express as
Resistance = 
..............1
V = I × R
and
V = I × 
..........2
put here value we get
9 = 280 ×
× 
ρ = 1.70 Ωm
Answer:
The Sun is a celestial body. It's a massive, spinning orb of heated gas that's glowing. The Sun is similar to the stars that may be seen in the night sky. The Sun is the centre of our Solar System, containing the majority of its mass. The Sun is the centre of our Solar System, and all of the planets, including Earth, revolve around it.
