Answer:
1.962 × 10⁻³ kW
Explanation:
The energy of a wave of a wave, such as an ocean wave, in regions of considerable water depth given its amplitude in a meter of crest and surface unit is given by the relation;
Where:
ρ = Density of water = 1000 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
A = Wave amplitude = 2 cm = 0.02 m
We therefore have;
The energy is power is the energy per second which is gives;
P = E /second = 1.962 J/s = 1.962 W = 1.962 × 10⁻³ kW.
Answer:
Yes is large enough
Explanation:
We need to apply the second Newton's Law to find the solution.
We know that,
And we know as well that
Replacing the aceleration value in the equation force we have,
Substituting our values we have,
The weight of the person is then,
<em>We can conclude that force on the ball is large to lift the ball</em>
Answer:
Fgrav. = GM1×M2/R2
Explanation:
Gravitational force is mostly related
to planetary bodies by Newton's law of gravitation which states that the gravitional force is proportional to the product of the mass of the object and inversely proportional to the square of the distance between them.
Hence in this case the Gravitational force,
Fgrav. = GM1×M2/R2
M1 and M2 are the mass of the two students and R is their distance apart
G is a constant known as gravitational constant.6.67408 × 10-11 m3/kgs2
Moshe Dayan said that the Freedom is the oxygen of the soul.
Oxygen is a plentiful and highly reactive element on the earth. Oxygen comprises about 21% of the earth's atmosphere. In its elemental form oxygen is a gas and diatomic.
The earth's crust contains a large amount of oxygen as well, primarily in the form of silicates. Many metals react with oxygen to form oxides. For example, copper reacts with oxygen to form copper (II) oxide. Iron reacts with oxygen to form iron(III) oxide (rust). Magnesium also reacts with oxygen, forming magnesium oxide.
Metalloids will also react with oxygen. Upon reaction with oxygen silicon forms silicon dioxide, the main component of sand.
Acid-base indicators are compounds that can measure the level of acidity for solutions. For example, phenolphthalein is a compound that is colorless in acidic solutions and pink in basic solutions.
