Answer:
The weight of water displace is equal to the weight of boat i.e, 200kg.
Explanation:
heat capacity: The capability of a substance to absorb heat energy; the amount of heat required to raise the temperature of one mole or gram of a substance by one degree Celsius without any change of phase.
is this what ur asking?
Answer:
71.56°
Explanation:
I₀ = Intensity of unpolarized light
θ = Angle between the axis of the filter and polarization direction
Intensity of polarzied light
Here, the light that is transmitted is reduced by 10% that means
I=0.1I₀
So,
∴ The angle between the axes of the polarizer and the analyzer is 71.56°
Gravity affects weight, it does not affect mass. Masses always remain the same. Newton's Second Law of Motion: Force = mass x acceleration The acceleration of an object is: a) directly proportional to the net force acting on the object. ... c) inversely proportional to the mass of the object.
Answer:
D.
Explanation:
Mass is conserved that means you can not change it, it is an absolute quantity.
Weight however is depanded on the mass of the planet that it is measured on it is by definition force that an object excerts downwards due to graity.
More gravity means more for.
Planet X has twice the mass of planet y so on planet X spaceship will have more weight.
Option D fits it.
