Answer:

Explanation:
In this case, since the charged particle moves in circular motion, the centripetal force is equivalent to the magnetic force.

D) 3 kg
One year is approximately 3 half lives of W-181. The amount remaining would be 1/23 or 1/8. That is 3 kg of W-181.
The jet fighter's acceleration at the highest point is 17.56 ft/s²
The jet fighter's acceleration at the lowest point is 35.12 ft/s²
The given parameters;
radius of the circular path, r = 1200 ft
constant velocity, v = 140 mi/h = 205.3 ft/s
The formula for centripetal acceleration in a circular path is given as;

The jet fighter's acceleration at the highest point is calculated as;
h = 2r = 2 x 1200 ft = 2,400 ft

The jet fighter's acceleration at the lowest point is calculated as;
h = r = 1,200 ft

Explanation:
It is agreed that the laws of Modern Soccer can be traced back to 1863 when new rules stated that players would no longer use their hands in football (futbol) except the goalie (its another term for the goalkeeper).
These rules were created by The Football Association (FA), the governing body of association football in the areas around England, and was formed in 1863.
Answer:
The speed of James is 0.776 m/s
Explanation:
Step 1: Data given
mass of James = 95.0 kg
mass of Ramon = 67.0 kg
We consider James and Ramon and the rope to a single system. This means that the net external forces on the system = 0
.The momentum = 0, so the sum of the momentum of each part must be 0 in total.
Step 2: Calculate the speed of James
m(james) *v(James) = m(Ramon) * v(Ramon)
with m(James) = the mass of James = 95.0 kg
with v(James) = speed of James = TO BE DETERMINED
with m(Ramon) = mass of Ramon = 67.0 kg
with v(Ramon) = speed of Ramon = 1.10 m/s
v(James) = (m(Ramon) * v(Ramon))/ m(james)
v(James) = (67.0 kg* 1.10 m/s) / 95.0 kg
v(James) = 0.776 m/s
The speed of James is 0.776 m/s
