c is the only fully correct option
Answer: Weight
Explanation:The mass of an object is a measure of the quantity of matter in the object. This quantity remains constant under any circumstance.
However, the same cannot be said about the weight of such object.
The weight of the object is very much dependent on the acceleration due to gravity which is a accelerational pull (by convention-- a pull downwards).
This is why an object tends to fall when it is thrown upwards on the earth for instance.
The statements above consequently infer that since the gravitational field of Jupiter is greater than that of the earth, the acceleration due to gravity on Jupiter is greater than that on earth.
And since the weight of an object(W) is a product of its mass and the acceleration due to gravity at that point.
Consequently, the object's weight on Jupiter would be greater than its weight on earth.
Please note; The Mass of the object remains constant everywhere.
This is another time to look at Newton's 2nd law of motion:
Net Force = (mass) x (acceleration)
If the object is not moving, then its acceleration is certainly zero, and Newton's law looks like this:
Net Force = (mass) x (zero)
or Net Force = (zero) .
"Net Force = zero" means that if there ARE any forces acting on the object, then they add up to zero, and we call them "balanced" forces.
So the answer is '<em>yes</em>', and that's why.
Answer:
4 %
2 ) 3.42 %
Explanation:
Sensitivity requirement of 4 milligram means it is not sensitive below 4 milligram or can not measure below 4 milligram .
Given , 4 milligram is the maximum error possible .
Measured weight = 100 milligram
So percentage maximum potential error
= (4 / 100) x 100
4 %
2 )
As per measurement
weight of 6 milliliters of water
= 48.540 - 42.745 = 5.795 gram
6 milliliters of water should measure 6 grams
Deviation = 6 - 5.795 = - 0.205 gram.
Percentage of error =(.205 / 6 )x 100
= 3.42 %
Answer:
Explanation:
As per thermal radiation we know that rate is heat radiation is given as
here we know that
T = 34 degree C = 307 K
e = 0.557
now we have
