Answer:
The horizontal distance x between the two balloons is 54.15 m
Explanation:
The diagram described as obtained online is presented in the image attached to this solution.
Let the horizontal distance between the two balloons be x
Difference in height (vertical distance) between the two balloons = 61 - 48.2 = 12.8 m
Using trigonometric relations, it is evident that
Tan 13.3° = 12.8/x
x = 12.8/tan 13.3° = 12.8/0.2364 = 54.15 m

Answer:
The gravitational force is significantly constant.
Explanation:
The gravitational force is expressed as:
F= G*M*m/d^2
G= Gravitational constant
M= in this case it is the mass of the planet
m= mass of the rock
d= distance of the rocks from the ground (suppose both at the same height for better comparison)
At the same time, we know that the force that each rock experiences is equal to the product of the mass due to acceleration:
F=m*a
We can match both expressions for F:
G*M*m/d^2 = m*a
we simplify m, and we obtain that the acceleration is independent of the mass of the attracted bodies:
a= G*M/d^2
Answer:
Explanation:
The magnitude of the magnetic force on the proton is given by:
where:
is the proton charge
is the proton velocity
is the magnetic field
is the angle between the direction of v and B
Substituting into the formula, we find
