Answer:
Explanation:
I=Q2- Q1
And I = F. (t2-t1)
t = 0,32s
v = 8,5 m/s
Q = m.v
Q=66,5.8,5 = 565,25 kg.m/s
F. (t2-t1) = 565,25
F.0,32 = 565,25
F = 1766,4 N
Answer:
Accuracy refers to how close a measurement is to the true or accepted value. ... Precision is independent of accuracy. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise. The best quality scientific observations are both accurate and precise.

Please give me brainly,
The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter). The more molecules an object has at a given temperature, the more thermal energy it has.
