Answer:
Matter is everything that surrounds us. It has mass and occupies a place in space. Matter can be described by measuring the value of its properties; for example: density, color, mass, volume, etc.
al ser homogenea no se puede percibir con la vista pero si se le agrega acido sulfurico la reaccion hara que el hidrogeno y el oxigeno se evaporen dejando unicamente una masa negra de carbono
No, ya que, es una mezcla homogénea, es decir, sus elementos están muy unidos mas no combinados de manera química, es posible separarlos pero con mucha dificultad, por tanto, es imposible diferenciarlos a simple vista. Se sabe que están distribuidos de manera uniforme, su estado es conocido como solución o disolución, tal como es el caso del azúcar.

Answer:
Speed of A = 891 km/h
Speed of B = 804 km/h
Explanation:
Let the speed of aeroplane B is v, the speed of aeroplane is A is 87 km/h faster than B.
So, the speed of aeroplane A is 87 + v.
Distance traveled by A after 7 hours, d1 = (87 + v) x 7
Distance traveled by B after 7 hours, d2 = v x 7
Total distance traveled = 11865 km
So, d1 + d2 = 11865
(87 + v) x 7 + v x 7 = 11865
609 + 14 v = 11865
14 v = 11256
v = 804 km/h
So, the speed of A = 87 + 804 = 891 km/h
Speed of B = 804 km/h
Yes it is consider biology
Answer:
Momentum of bullet
momentum of baseball
Explanation:
As we know that momentum is defined as the product of mass and velocity
here we know that
mass of the bullet = 8 gram
velocity of bullet = 340 m/s
momentum of the bullet is given as
Now we have
mass of baseball = 0.2 kg
velocity of baseball = 40 m/s[/tex]
momentum of baseball is given as
Answer:
B. 2nmv
Explanation:
Pressure is force over area.
P = F / A
Force is mass times acceleration.
F = ma
Acceleration is change in velocity over change in time.
a = Δv / Δt
Therefore:
F = m Δv / Δt
P = m Δv / (A Δt)
The total mass is nm.
The change in velocity is Δv = v − (-v) = 2v.
A = 1 and Δt = 1.
Plugging in:
P = (nm) (2v) / (1 × 1)
P = 2nmv
