a direction perpendicular to the direction of propagation of the wave, it is called a transverse wave.
Answer:
the answer is option d
because in oven which works through electricity ,it will bake the cake (heat energy is produced)
Since there is no friction between the ladder and the wall, there can be no vertical force component. That's the tricky part ;)
So to find the weight, divide the 100N <em>normal</em> force by earths gravitational acceleration, 9.8m/s^2

Then;
Draw an arrow at the base of the ladder pointing towards the wall with a value of 30N, to show the frictional force.
Answer:
r = 0.0548 m
Explanation:
Given that,
Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.
We need to find the radius of their circular path. The formula for the radius of path is given by :

m is mass of Singly charged uranium-238 ion, 
q is charge
So,

So, the radius of their circular path is equal to 0.0548 m.
