An element becomes a + ion when it...loses electrons
The answer is A,B,C that apply. I believe this is the answer i hope this helps have a good day.
The pressure of a submerged object in a fluid is given by:
where ρ is the density of the fluis, g is the acceleration of gravity, h is the depth of the object and Patm is the pressure of the atmosphere. In this case we know that:
• The density of water is 1000 kg/m^3
,
• The acceleration of gravity is 9.8 m/s^2
,
• The depth of the object is 3 km, that is, 3000 m.
,
• The atmospheric pressure is 101325 pascals.
Plugging these values in the equation given above we have:
Therefore, the pressure at this depth is 2.95x10^7 Pa.
Answer:
Given,
Explanation:
mass(m)=2400kg
velocity(v)=15m/s
kinetic energy(K.E.)=1/2mv2
KE=1/2×2400×15^2
=1/2×540000
=270000Joule
