Answer:
Explanation:
The force exerted on a charged particle due to a magnetic field is given by:
where
q is the charge of the particle
v is the velocity of the particle
B is the magnetic field strength
is the angle between the directions of B and v
In this problem we have:
is the charge of one honey bee
is the velocity of the bee
is the average strength of the Earth's magnetic field
, because the bee flies east to west while the Earth's magnetic field is south to north
Substituting into the equation, we find:
To calculate the ideal mechanical advantage of a lever divide the input arm by the output arm.
Mechanical advantage is the amount by which a machine can multiply an input force, calculated by dividing output Force in newtons by input force in newtons, while the ideal mechanical advantage is the mechanical advantage of a machine that has no friction, calculated by dividing the input distance by the output distance.
D make one revolution around the sun hope this helps
Answer:
120 km/h
Explanation:
This is a case of a parabolic motion. For this kind of motion the horizontal component of the velocity does not change in the complete trajectory. That is:
Then, the velocity of the ball at the moment in which the catcher caught the ball is:
the velocity of the ball is 120 km/h.
According to Newton's 3rd law of motion, every action has an equal and opposite reaction.
So Wall must apply a force of 50 Newton but in opposite direction.
Hope you got it :-D
