Buoyant force is equal to the weight of the total amount of liquid displaced by an object when submerged partially or completely in the fluid. This means that if an object that has a volume of 2m³ has 50% (1m³) of its volume submerged in water, the buoyant force will be equal to the weight of 1 m³ of water, this is about 1000kg.
With this in mind, the buoyant force will be equal to the weight of the amount of fluid that has the same total volume as the object when the object is completely submerged, this is to say, it has its total volume under the fluid.

I'll report you if you don't actually help. I'd like an actual explanation, please.
Hey
So first we need to know what the direction of the force is, using your right hand rule point your right hand in the direction of the velocity. You're saying its the z direction, not telling me whether it's into the page or out? Since its a positive z im assuming its coming out. The magnetic field is pushing it upwards, so the force is going in the negative x direction.
The force of a magnetic field is
F = Qv X B
What's weird is that you don't need mass in this equation. Actually you don't even need the formula, its telling you that they're all going in perpendicar directions. the answer is 90 degrees.
Now if you want to know the F just multiply the charge, velocity and magnetic field .
F = GVB
F = 6.048 E -15
Answer : 90 degrees, sin(90) = 1
To find the magnitude and direction of the magnetic force on a proton moving in a magnetic field, you can use the equation F = qvBsinθ, where F is the force, q is the charge, v is the velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field. The magnitude of the magnetic force can be calculated using the equation, and its direction can be determined using the right-hand rule. In this case, the angle between the proton's velocity and the magnetic field is 90°.
To determine the magnitude of the magnetic force on the proton, we need to use the equation F = qvBsinθ, where F is the force, q is the charge, v is the velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field.
Plugging in the values, we have F = (1.6 × 10-19 C)(1.8 × 105 m/s)(2.1 × 10-1 T)sinθ.
To find the angle θ, we can use the fact that the force is perpendicular to both the velocity and the magnetic field, which means that sinθ = 1.
Therefore, the magnitude of the magnetic force on the proton is F = (1.6 × 10-19 C)(1.8 × 105 m/s)(2.1 × 10-1 T) = 6.048 × 10-14 N. The direction of the magnetic force is given by the right-hand rule, which shows that the force is perpendicular to both the velocity and the magnetic field, pointing in the positive x-direction.
The angle between the proton's velocity and the magnetic field is 90°.

b. large
c. small
d. unbalanced
Before solving this question first we have to understand Newton's first law of motion
As per Newton's first law it is impossible to change the state of rest or uniform motion along a straight line unless and until it is compelled by some external unbalanced forces.
Everybody tends to oppose the change of state of rest due to their inertia.A book present on a table pushes the table with its weight in vertically downward direction while table applies same amount of force on the book in vertically upward direction.The net force acting on each body is zero.So the book will show no motion.
Actually balanced force have no role in changing the state of rest of the body. Only unbalanced force will cause the body to move.
Hence the washer who does not want to change his position will want the force acting on him to be [balanced ].
b. Mars and Jupiter.
c. Jupiter and Neptune.
d. Mars and Earth.
Answer:
b. Mars and Jupiter.
Explanation:
Asteroids are irregular sized and shaped rocky bodies -very small as compared to a planet which revolve around the sun in elliptical orbit. In the solar system, majority of the asteroids can be found in the asteroid belt which lies between the orbits of Mars and Jupiter. It is thought to be the debris of an unformed planet due to large gravity of Jupiter. Examples of asteroids - Ceres, Vesta, Eros etc.
B. Potential energy decreases, then increases to the original level.
C. Potential energy remains the same throughout the ball's trajectory.
D. The answer cannot be determined from the information provided.
Answer:a
Explanation:
Answer:
A heretic because his beliefs disagreed with the church
As 2 objects get closer and closer due to the gravitational attraction, the force between them C. increases.
Two objects move toward each other because of gravitational attraction. To understand the gravitational force, we need to consider Newton's law of universal gravitation, which states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically,
where,
As the objects get closer, the distance between them decreases, and consequently the gravitational force increases.

Answer:
C. increases
Explanation:
Law of Universal Gravitation
This law establishes that bodies, by simply having mass, experience a force of attraction to other bodies with mass, called gravitational force or gravitational force.
The gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them.
Formula (1)
where:
G is the universal gravitation constant, G = 6.67 · 10-11 N · m² / kg²
M and m are the masses of the bodies that interact (kg)
r is the distance that separates them. (m)
Problem development
As objects get closer and closer the distance (r) that separates them decreases and because M, m and G remain constant, in formula (1):
, if r decreases then Fg increases.
