<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
Answer:
The potential difference across a given given wire of an circuit is directly proportional to the current flowing through it provided it's temperature remains the same. This is known as ohm's law
V is proportional to I
V/I = constant
V/I = R
V = IR where R is the constant of proportionality and resistance of the wire
Hope this helps!
Answer:
A scientific model is an activity that is aimed at making a specific part or feature easier to understand and define.
Modeling is an essential scientific discipline and is used in the fields of education. Modeling seems to represent empirical objects, phenomena in a logical and objective way.
The oval-shaped world map showing vegetation in green color is a 2D model of the entire earth and demarcates us the world vegetation distribution and growth.
Hence this is a scientific model as its helps in visualizing the land surface of the earth on paper.
Explanation:
Yes because a scientific models doesn't have to be complex, just like this one
