Answer:
-142m
Explanation:
To find the initial position of the car, we can add the displacement.
-245 + 103 = -142
Best of Luck!
Mass is scalar physical quantity wich is measured by kg. and only expressed by its magnitude
Answer:
F1 = 80
Explanation:
f1= f2 √ (F1/F2)
Where f1 = 300, f2 = 260 and F2 = 60
Putting in the above formula
300 = 260√(F1/60)
Dividing both sides by 260
=> 1.15 = √(F1/60)
Squaring both sides
=> 1.33 = F1/60
Multiplying both sides by 60
=> F1 = 80
Answer:
5 atoms of Boron
Explanation:
Boron makes up approximately 15.944% of the mass and the rest of the 84.056% is Fluorine. There is 5 Atoms because Boron atomic mass is 10.811 in 1 molecule of BF3 and you wanted 5 Molecules.
The statement ‘The Biot-Savart
force law does not apply if the velocity is parallel to the field direction’ is
true. The answer is letter A. Any electron moving in a conductor will produce a
magnetic fiels around the flow. this is the fundamental of Biot – Savart law.
