Answer:
Solid: metal alloy
Liquid: beer
Gas: Air
Explanation:
A solution is a type of mixture where the solvent and solute are homogeneously mixed. Homogeneous mixture means that the solute shouldn't be able to be seen with the naked eye, filtered and stable enough.
Metal alloy will be an example of a solution in solid-state. Beer is a solution made of liquid alcohol and liquid water. Air mostly composed of nitrogen, but it has oxygen, carbon dioxide, and many other substances in gaseous form.
I suppose that you wanted write "uncharged". The particles without electrical charge present in the nucleus are called neutrons.
You just multiply these two numbers. It's 5200J, or 5.2kJ
Answer:
Before: 0 m/s
After: -4 m/s
Explanation:
Before: Since you and your beau started at rest, your beau initial velocity is 0 m/s.
After: Since we have to conserve momentum,
momentum before push = momentum after push.
The momentum before push = 0 (since you and your beau are at rest)
momentum after push = m₁v₁ + m₂v₂ were m₁ = your mass = 60 kg, v₁ = your velocity after push = 3 m/s, m₂ = beau's mass = 45 kg and v₂ = beau's velocity.
So, m₁v₁ + m₂v₂ = 0
m₁v₁ = -m₂v₂
v₂ = -m₁v₁/m₂ = -60 kg × 3 m/s ÷ 45 kg = -4 m/s
So beau moves with a velocity of 4 m/s in the opposite direction
Answer:
(a)7.48331 Km
(b) Directly above the tomb
(c) 12.53 degrees
Explanation:
Given that the distance is 3.5 Km, converted to meters we obtain 3500 m
Using the formula
where s is the distance and t is time, taking acceleration due to gravity as 9.8 then
t = 26.72 sec
We know that speed=distance/time hence to get the distance in part (a)
Distance=Speed*time
280 *26.72 = 7483.31 m converted to Km we obtain 7.48331 Km
(b)directly above the bomb
(c)
