Calcium ions have a +2 charge and sulfur ions have a -2 charge, so the formula is CaS
Answer:
Explanation:
From the question we are told that:
Charge 
Velocity 
Angle 
Magnetic field 
Generally the equation for Force is mathematically given by
Therefore
Answer:
66.053m/s
Explanation:
A = 47
B = 347
C = 19
Train moves at
(23 + A)m/s
= 23 + 47 = 60m/s
At (250.0+B) seconds
250.0+347 =
547 seconds
Distance d,
= 70 x 597
= 41790
It also moves at
(45.0 + c)
= 45 + 19
= 64m/s
Time = 800 + B
= 800 + 347
= 1147
Distance,
= 64 x 1147
= 73408m
Total distance,
= 73408 + 41790
= 115,198
Total time,
= 597 + 1147
= 1744
Average speed,
= Total distance / total time
= 115198/1174
= 66.053m/s
Newton's 1st law of motion states that <span>an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia</span>
