Answer:
B = 5.59x10⁹ T
Explanation:
The magnetic force (F), on a the alpha particle with charge (q) that is moving at velocity (v) as the cross product of the velocity and magnetic field (B) is:
<u>We have:</u>
F = 1.4x10⁻³ N
v = 2.6x10⁶ m/s
θ = 37.0°
q = 2*p = 2*1.6x10⁻¹⁹ C
Hence, the strength of the magnetic field is:

Therefore, the strength of the magnetic field is 5.59x10⁹ T.

From laws of motion:

Where S is the distance/displacement (as you would call it) which is unknown
v = final velocity which is 0m/s (this is because the car stops)
u = initial velocity which is 36m/s (from the data given)
t = time taken for the distance to be covered and it is 6s
Substitute the values, hence:


But this is merely the distance he travelled in the 6 seconds he was trying to stop the car.
Therefore, the distance between the car and the cows = 160-108
Distance = 52m
Newton's First Law Example: Driving a car and hitting something like a tree, the car will stop instantly but you'll keep moving forward. Cars have airbags because of this.
Newton's Second Law Example: It's easier to push a box without anything inside it than a box full of stuff because the box that is full has more mass than the empty one.
Newton's Third Law Example: When air rushes out of a balloon, the opposite reaction is that the balloon will fly around the room.
Pulling open a door, your weight, and a magnet on your refrigerator
Answer:
Explanation:
Given
initial horizontal speed of =6.55 m/s
height of rock=1.4 m
Horizontal distance=8 m
Time to travel 8 m


Time to cover 1.4 m
