Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.
Add all the forces to find the net force on the squirrel. -2N+3N=1N
Because the positive direction is to the right, the net force of 1N is directed to the right.
Answer:
Earth Day is observed globally
Explanation:
It will not explode since the mass of the cotton balls is so low but rather will most likely break the lock and hinges and come out.
Answer:
(a) Current will be
(b) Number of ions will be
Explanation:
We have given that resistance of the biological cell
(a) We have given potential difference of 75 mV
So
From ohm's law we know that current is given by
(b) We have given time t = 0.74 sec
We have to find the charge
We know that charge is given by Q = it, here i is current and t is time
So charge will be
So number of ions will be
Answer:
145 degree
Explanation:
We are given that
Magnetic field=B=2 T
Charge on particle,q=
Velocity, v=
Angle,
We have to find the direction of the force exerted on this particle by magnetic field with magnitude 2 T in the z direction.
Component of velocity along x- axis
Along y- axis
Hence, the direction of force =145 degree
