Its mass, I suppose. Unless the balloon explodes.
Answer:
Explanation:
Different measuring instruments have different level of precision . For example , our usual scale can measure upto 1 mm. Callipers can measure upto .1 mm. screw gauge can measure upto .01 mm.etc The deeper it can measure , the more precise it is. Hence screw gauge is most precise among the three.
On this basis we can say that , new caliper is less precise than old one.
Accuracy tells us about our result , how close our result is to the true measurement. It is dependent on the manner in which we take reading , So measuring methods , rather than measuring instruments , decide the accuracy of our result.
Hence we can say that the new caliper is less precise only.
Answer:
the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion is called kinematics.
Answer:
I think it's D!!
cuz protons are in the atoms
Answer:
the total force vector, on test charge is points from origin to point C( 1, 1 )
Explanation:
Given the data in the question, as illustrated in the image below;
from the Image, OA = 1, OB = AC = 1
so using Pythagoras theorem
a² = b² + c²
a = √( b² + c² )
so
OC = √( OB² + AC² )
we substitute
OC = √( OA² + AC² )
OC = √( 1² + 1² )
OC = √( 1 + 1 )
OC = √2
Coordinate of C( 1, 1 )
Hence, the total force vector, on test charge is points from origin to point C( 1, 1 )
