Answer:

FALSE

Explanation:

As we know that the friction force between two sliding surfaces is given by the formula

$F_f = \mu F_n$

here

$\mu$ = coefficient of friction

it depends on the the inter molecular force between the molecules of the two surfaces which slide over each other

now if we will increase the normal force then it will increase the force of friction

but if will not change the value of coefficient of friction between two surface as it is property of the surface only

A transverse wave on a string is described by the wave function y(x, t) = 0.350 sin (1.25x + 99.6t) where x and y are in meters and t is in seconds. Consider the element of the string at x=0. (a) What is the time interval between the first two instants when this element has a position of y= 0.175 m? (b) What distance does the wave travel during the time interval found in part (a)?

A seagull flies at a velocity of 9.00 m/s straight into the wind. (a) if it takes the bird 20.0 min to travel 6.00 km relative t

enot [183]

Here we will the speed of seagull which is v = 9 m/s

this is the speed of seagull when there is no effect of wind on it
