Answer:12.206 cm,
Explanation:
Given
Insect walks 15 cm to the right
so its position vector is
Now it moves 10 cm up so its new position vector

Now it moves 8 cm left so its final position vector is

so its displacement is given by

For direction, let \theta is the angle made by its position vector with x axis


Answer:

Explanation:
As we know that the force per unit length of two parallel current carrying wires is given as

here we know that


d = 2.2 cm
now from above equation we have



The acceleration of gravity on Earth is 9.8 m/s² downward.
This means that gravity adds 9.8 m/s downward to the speed
of a freely falling object every second.
So after 25 sec, it's falling (25 x 9.8m/s) = 245 m/s faster than
it was falling at the beginning of the 25 seconds.
If it dropped from rest (no speed), then its velocity
after 25 seconds is 245 m/s downward.
Answer:
a) Impulse(J)=40.04 kg.m/s
b)F=2566.66 N
Explanation:
Given that

We know that impulse(J) impulse is a vector quantity

We know that P=mV
So
Now by putting the values
J=1.3(9.8-(-21))
So impulse(J)=40.04 kg.m/s
Force is given as

or we can say that

So 
F=2566.66 N
