A wire has a current flowing through it as shown in the figure, What is the direction of the magnetic
field at point "A?
a ( into the page )
b ( left)
c ( out of the page )
d( down )

the results is a decrease in air temperature with an increase of altitude.

explanation:

true is the correct answer

hope i

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

because if the tool that you are using is not balanced it there would be false mass.
