Answer:
1.991 × 10^(8) N/m²
Explanation:
We are told that its volume increases by 9.05%.
Thus; (ΔV/V_o) = 9.05% = 0.0905
To find the force per unit area which is also pressure, we will use bulk modulus formula;
B = Δp(V_o/ΔV)
Making Δp the subject gives;
Δp = B(ΔV/V_o)
Now, B is bulk modulus of water with a value of 2.2 × 10^(9) N/m²
Thus;
Δp = 2.2 × 10^(9)[0.0905]
Δp = 1.991 × 10^(8) N/m²
Force is equal to mass multiply by acceleration.
force is also equal to mass multiply by gravity
F=ma
F=mg
<u>Answer:</u>
<u>Explanation:</u>
Given data,
- mass of the crate, m = 200 kg
- height of the shipping container, h = 45 m
- gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
P.E = 200 x 9.8 x 45
= 88,200 J
Hence, the <u>gravitational potential energy</u> of the crate <u>is, P.E = 88,200 J</u>
Answer: option d: The nucleus of Atom Q is more stable than the nucleus of Atom P.
Explanation:
Atom P is radioactive and disintegrates, it emits beta particles (high speed electrons or positrons) because it is not stable. On disintegration, it forms a stable Atom Q which is non-radioactive and thus it does not disintegrates further.
Thus, the correct option is only d. The nucleus of Atom Q is more stable than the nucleus of Atom P.
The correct answer of this question is : From high potential to low potential.
EXPLANATION :
Before going to answer this question, first we have to understand the conventional rule for current flow.
As per the conventional rule of electricity, the current direction is opposite to the direction of electronic motion.
The current flows through a conductor is due to the motion of the free electrons. When the conductor or wire is attached to any electric source, the electrons are drifted towards the positive terminal of the source. Hence, electrons are moving from negative terminal to positive terminal.
As per the conventional rule, the current direction will be from positive terminal towards negative terminal i.e from higher potential to lower potential.
Hence, the correct answer of this question is from higher potential to lower potential .
