Answer:
the buoyant force on the chamber is F = 7000460 N
Explanation:
the buoyant force on the chamber is equal to the weight of the displaced volume of sea water due to the presence of the chamber.
Since the chamber is completely covered by water, it displaces a volume equal to its spherical volume
mass of water displaced = density of seawater * volume displaced
m= d * V , V = 4/3π* Rext³
the buoyant force is the weight of this volume of seawater
F = m * g = d * 4/3π* Rext³ * g
replacing values
F = 1025 kg/m³ * 4/3π * (5.5m)³ * 9.8m/s² = 7000460 N
Note:
when occupied the tension force on the cable is
T = F buoyant - F weight of chamber = 7000460 N - 87600 kg*9.8 m/s² = 6141980 N
Vê quantidade de movimento precisa ta em kg.m/s certo?
a questão disse que a gravidade é de 10 int posso dizer q minha massa é de 36kg pois p(360n)= massa . gravidade(10).
ja a velocidade esta km/h int vou dividir por 60 por 3,6 ou 600 por 36, aumentando de 10 vezes pra poder ajudar no calculo.
quantidade de movimento é Q= m(36) . velocidade( 600/36)
Q= 36.600/36 se corta 36 de cima com o 36 de baixo vai ficar 600kg . m/s
Answer:
The ocean liner
Explanation:
Given that,
The mass of the bullet, m = 0.0014 Kg
The velocity of the bullet, v = 396 m/s
The mass of the ocean liner, M = 7.1 x 10⁷ Kg
The velocity of the ocean liner, V = 13 m/s
The kinetic energy is given by the formula,
K.E = 1/2 mv²
1) The kinetic energy of the bullet,
K.E = 1/2 x 0.0014 x 396²
= 109.775 J
2) The kinetic energy of the ocean liner,
K.E = 1/2 x 7.1 x 10⁷ x 13²
= 6 x 10⁹ J
Hence, the ocean liner has more kinetic energy.
An atom is made up of three different particles, which are proton, neutron and electron. The proton and the neutron are located in the nucleus of the atom and they make up mass of the atom. The electron orbit around the nucleus. The proton is positively charged while the electron is negatively charged, thus, for the atom to remain neutral, the number of proton and electron in an atom must be equal. The neutron has no charge.
The atomic mass of an element = number of proton + number of neutron
Atomic mass of magnesium= 24
Number of proton = 12
Therefore, number of neutron = 24 - 12 = 12.
Thus, the number of neutron = 12.
Answer: This means that the objects didn't hold or have any charges before it was charged by something or someone
Explanation:
Like a dead phone it dosn't have any "charge", but after you put the charger in the wall you can plug the phone in and get it charged It's an on going cycle of energy being turned into other energy.
